Primobolan (Methenolone) is a unique steroid in several ways including that it’s one of the few you can get in both oral and injectable forms. It is one of the best suited steroids for females, and despite its low anabolic rating it is still a sought after steroid by people who know exactly what they want to use it for, and how to use it for maximum effect.
Methenolone was originally developed to treat medical conditions that caused muscle wasting. This highlights how effective this compound is at preventing loss of muscle, which is a highly desirable trait for any bodybuilder or athlete.
While not a powerful bulking steroid and one that won’t contribute much to size gain in most men, it is an excellent cutting compound due to the way Primobolan is able to help retain lean muscle tissue mainly through the process of increasing nitrogen retention.
Author’s Note: The following guide is based on my personal experience and does NOT promote the illegal use of steroids (PEDs). I am currently using this supplement stack.
In this guide, you'll learn:
What is Primobolan?
Primobolan is a steroid that comes both in oral and injectable forms, with the injection tending to be more popular with performance athletes. It’s been said that Primobolan was a favored steroid used by Arnold Schwarzenegger in his prime and this is likely one of the reasons it remains popular with bodybuilders today.
Finding high quality and genuine Primobolan can be a challenge with counterfeits being common, particularly with the oral form. So before you even consider using Primobolan, make sure you can source it from a reliable supplier.

Methenolone Enanthate (Primobolan Depot)
Depot is the name of the injectable form of Primobolan. It is considered to be a more effective and slightly more powerful form of Primobolan, but the effects are still similar to the oral form and it remains a relatively mild steroid compared with most others out there.
Just like oral Primobolan, Depot isn’t a mass gaining steroid but provides the most benefit during cutting cycles where you need to retain maximum muscle while burning fat and eating a lower calorie diet.
Females are more likely not to choose Primobolan Depot as the oral form is generally better tolerated and controlled with a lower risk of side effects.
Methenolone Acetate (Oral Primobolan)
The oral form of Primobolan is Methenolone Acetate in chemical form, with the acetate being a small ester attached to the Methenolone hormone so it can be consumed in oral form. Unlike many other oral steroids, Primobolan doesn’t come with the high risk of liver toxicity; in fact there are virtually no known causes of liver stress or damage caused by this steroid.
The mild anabolic effects of oral Primobolan make it an ideal choice for women who can see excellent results at low doses with relatively low risk of virilization side effects compared with other steroids. While oral Primobolan can also be effective for male users, many men will prefer the injectable Depot version which is considered to be more effective.
Due to the difficulty in obtaining high quality Primobolan, not everyone will have the option to choose between oral or depot, with the choice often resting simply on what you are able to obtain. Cost will also be a factor in your decision between the two formats, as this can be a very expensive steroid to run.
It’s not unusual for a 50mg tablet to cost $3.50 each from a quality underground lab or $25 per 100mg ml of Primobolan depot. These costs must be considered before planning which format you wish to use and whether you can afford an entire cycle in combination with any other steroids you plan to stack Primobolan with.
Primobolan is derived from DHT so you can expect it to have a lot of the same properties and effects as that hormone including the benefit of it not being an aromatizing hormone. This makes it a powerful compound for cutting because you can achieve a very cut and lean look without the bloating caused by fluid retention.
Here are the main benefits and effects of Primobolan:
- Promotes nitrogen retention: this is what makes Primobolan so useful for retaining muscle tissue during a cutting cycle and what makes it the main reason people use this steroid.
- Enhances immune system: this is an important side benefit because we as steroid users need the immune system to be as strong as possible for maximum strength, energy, mental focus and all round health. During a cutting cycle in particular where you are eating less, the immune system can take a hit and this is where Primobolan brings some extra benefit during a cutting cycle.
- Gain a lead and hard physique: with its ability to promote the preservation of lean muscle without the side effects we must dread when losing fat – water retention and gyno – Primobolan is an excellent compound to use when achieving the ultimate hard, toned and defined physique is the main goal.
Here are the areas where Primobolan is not going to be your ideal steroid to use:
- For bulking and mass gains: Primobolan has mild anabolic properties so is not primarily used for gaining muscle and size in a bulking cycle.
- Strength: Again due to its lower anabolic rating compared with many other steroids, only mild gains in strength can be expected so if you’re looking for massive strength gains there are other steroids that will suit you instead of Primobolan.
Because of its relatively low anabolic rating, using Primobolan with any benefits normally means dosing it at a higher level than we might for most other steroids. These higher doses still only make Primobolan most effective for cutting cycles, as the dosing required for bulking would be too high to be practical or healthy.
Whatever your goals are, Primobolan is almost always stacked with other steroid compounds as it tends to have little beneficial effect when used alone for most men, but can be effective for women.
Injectable Primobolan (Primobolan Depot) Dosage
Injecting Primobolan gives you the best effects of this steroid and is the option most serious users will want to consider. It stacks well particularly with other non-aromatizing steroids that can often be conveniently administered in the same injection.
Beginner, Intermediate, and Advanced Dosage
Using injectable Primobolan during a cutting cycle will have the same goals no matter what your experience level is: namely to preserve your lean muscle while you’re on a calorie restricted diet to lose fat. The gaining of new muscle isn’t desirable at this stage and Primobolan is not a muscle gainer, even at higher doses.
Beginners can see good results with injectable Primobolan at 400mg weekly and this is considered to be the lowest effective dose – any lower and Primobolan is unlikely to have a noticeable benefit.
Intermediate users can increase the weekly dosage to 700mg, with advanced Primobolan users able to inject up to 1000mg while still retaining minimal side effect risks.
Splitting the dosage into a twice weekly injection is the standard procedure and this will ensure your blood levels of Primobolan remain at the optimal level.
Proper Administration and Timing
Injectable Primobolan has a much longer half life than the oral form at up to ten days, so daily administration is not needed to retain levels of the steroid.
Twice weekly injections work well for most people and ensure that Primobolan is maintained at an optimal level for the duration of your cycle. This means splitting your dose in half each week and making sure that there is a consistent gap between each injection, usually of three days.
The mild anabolic effects of Primobolan can suit female users well as this steroid is nowhere near as powerful as many others. Women using Primobolan can expect quality performance and physique enhancement results using low doses which are unlikely to produce the masculinization that are such a high risk with most other steroids.
A daily dose of between 50mg and 100mg is more than enough for female users to get excellent benefits with low risks of side effects. More advanced females can increase the injectable dose up to 200mg but need to be aware of the higher risk of virilization.
Oral Primobolan (Methenolone Acetate) Dosage
The oral form of Primobolan is clearly preferable for anyone who is hesitant about injecting themselves with steroids, but it’s well known that despite the compound being the same besides the attached ester, oral Primobolan is not quite as effective as the injection and this can just be to do with how its taken up by the body.
In any case, if the oral form is the only one you can get your hands on or you simply don’t want to deal with injections then it’s still well worth using as long as you get your doses right optimized for best results.
Beginner, Intermediate, and Advanced Dosage
Its mild nature means that we need to use Primobolan at a higher dosage level than might be the case with most other steroids, and this will include beginner users as well. The good news is that even at these higher performance enhancement doses, Primobolan does not present huge side effect risks and should be well tolerated by beginners.
Both beginners and intermediate users can safely use Primobolan up to 150mg daily, although beginners wanting to start off extra slow can lower this down to 50mg and potentially see some beneficial effects still.
Advanced users often increase the oral dose up to 200mg daily, keeping in mind that these doses are unlikely present the risks of liver toxicity that is the case with almost all other oral steroids where doses need to be limited for that reason.
Advanced users choosing to increase Primobolan oral doses beyond 200mg daily should be aware of an increased risk to the liver at higher dosages.
The high cost of oral Primobolan is often a limiting factor in what you’d like your daily dosage to be regardless of experience level.
Whatever your chosen dose of oral Primobolan is, it can be taken in one administration and there is no need to split the dose as is the case with the injectable form.
Proper Administration and Timing
Taking Primobolan oral is as simple as a once daily administration. While some other steroids with very short half lives might need a dose to be broken down into twice or more daily to sustain levels of the hormone, this is not an issue with the longer half life of Primobolan of several days.
Women only require mild anabolic effects from a steroid to experience gains in muscle, and Primobolan fits the bill and comes with much less risk of virilization effects than almost any other steroid.
Oral Primobolan is preferred by females as both the effects and side effects are easier to control compared to the injection. Females can get by with excellent benefits at very low doses of oral Primobolan of just 50mg, or 75mg maximum.
So you’ve decided on what form of Primobolan you want to use and what dosage you’re comfortable with to achieve your results. How can you fit this steroid into a cycle? Below are some typical examples of how Primobolan is used in a cycle and as you will see, it is virtually always used with other steroid compounds.
Beginner Primobolan Cycle
By making use of injectable Primobolan combined with a testosterone ester of a similar acting nature, your administration of each compound can be done at the same time, making this a very simple to implement cycle for a beginner introducing themselves to Primobolan.
Testosterone enanthate is the ideal form to use in this case, as it contains the same ester as is attached to injectable Primobolan. Beginners undertaking this cycle can safely use 400mg per week of Primobolan and up to 500mg weekly of Testosterone enanthate, although it will still be very effective as low as 300mg weekly.
These compounds can even be taken in the same injection by combining them together, making it one simple injection per dose. A 10 week cycle will provide excellent results and help you evaluate how these steroids affect you both positive and negatively as a beginner.
Intermediate Primobolan Cycle
Intermediate users wanting to take the option of oral Primobolan will often make use of a testosterone compound simply to provide a base level of testosterone support during the cycle but not as a primarily anabolic compound.
This just ensures that your normal testosterone function is retained during the cycle, while leaving the other compounds to deliver the results you’re after. For a cutting cycle the best compound to combine with Primobolan is Winstrol as both are derived from DHT and neither of these steroids aromatize.
This intermediate cutting cycle, when used with a calorie controlled diet and proper workout program, will deliver a hard, toned and defined physique with no water retention. Although Primobolan contributes little to muscle gain, Winstrol does provide some scope for mass gain during this cycle.
This intermediate Primobolan cycle is easy to implement at the following doses: 100mg daily of oral Primobolan, 400mg per week of injectable Winstrol and Testosterone Enanthate as a support compound at just 100mg weekly. This cycle can safely be run for 10 weeks.
Advanced Primobolan Cycle
The most advanced and experienced users of Primobolan will also have extensive experience in using other anabolic steroids and feel confident in combining them in a cycle for maximum outcomes and this will usually be for serious cutting purposes including competition preparation where you want maximum definition and hardness by the end of the cycle.
Including testosterone as a support compound similar to the intermediate cycle is the ideal option for advanced users as well, but the big difference in this advanced cycle will be the addition of the extremely powerful anabolic steroid Trenbolone. Testosterone therefore is not used as a bulking or strength gainer in this cycle, leaving that role to Trenbolone.
Just like Primobolan, Trenbolone is not an aromatizing steroid so your results come without the bloated look caused by water retention, and this is critical for a cutting cycle particularly when it’s for a competition. All three steroids in this cycle are in an injectable form. But even more so, they both come with the same ester attached so can conveniently be combined and taken all within the one single injection.
A 10 week cycle will produce exceptional results, with the following doses: 1000mg per week of Primobolan Depot, 500mg per week of Trenbolone and 100mg weekly of testosterone enanthate as a testosterone support compound.
Primobolan is almost always stacked with other steroids, with the exception being for female users who find that the mild anabolic rating is a perfect fit for gaining some size without the serious virilization side effects. Males however will utilize other compounds depending on the goal of the cycle and these are seen above in the beginner, intermediate and advanced cycle examples.
Taking care to stack compounds that are similar in their structure concerning the attached esters will make it very easy to make use of Primobolan in combination with other steroids, including being able to administer them in the one injection.
Additionally by selecting steroids to stack with Primobolan that also come with the same benefit of not being aromatizing compounds and thus not coming with estrogenic side effects, you can run some very powerful cycles, as seen above, without having to deal with side effects like gyno and water retention.
Being a much milder steroid on the anabolic side compared with the famous mass building and bulking steroids out there, your results with Primobolan won’t be including big muscle gains but that’s not what this steroid should be used for and attempting to take higher doses to improve muscle growth is a futile exercise – you are much better off going with more powerful anabolic steroids if bulking is your main aim.
In a cutting phase is where Primobolan will contribute to impressive results. Expect a hard and defined physique because there is no water retention caused by Primobolan (if you are stacking it with other steroids that cause water retention that side effect will need to be controlled).
Primobolan will play a critical role in retention of muscle tissue while you’re cutting by keeping the body anabolic and avoiding catabolism. Primobolan encourages the body to use fat for energy and not resort to using muscle for energy; it also helps to burn fat more efficiently. With no water retention it’s possible to attain a hard, dry and chiselled physique once your fat levels are at a low level.
Primobolan Side Effects
Compared with many other steroids, Primobolan is considered to be well tolerated by most people and relatively mild in its side effects.
The good news is that there are no estrogenic side effects to worry about when you use Primobolan. This is because Methenolone is a non-aromatizing hormone and it also doesn’t have any effects on progestin which can also cause estrogen type side effects so you get to avoid some of the worst side effects experienced with most other steroids.
But we can’t expect to get away with no side effect risks when it comes to anabolic steroids and Primobolan makes up for it on the androgenic side, but again these are relatively weak effects compared with other steroids because of its lower androgenic rating of about half that of testosterone.
This still means some people will experience androgenic side effects and the risk mostly depends on your individual genetics and predisposition to these effects.
Females are obviously at much greater risk of the androgenic effects taking hold and producing issues like body hair growth, but Primobolan at lower doses in women is considered one of the safest steroids to use and these side effects are often completely avoided.
Most androgenic effects on men using Primobolan are generally very mild to non-existent in most people, but can include acne or the triggering of hair loss on the head if your genes predispose you to these.
Oral steroids often come with severe risks to the liver, but Primobolan has a slightly different chemical structure to most oral steroids and so is a much lower risk of hepatotoxicity. This doesn’t mean there is zero risk of the liver being affected though, but lower doses of oral Primobolan are safer than most other oral steroids. Higher doses or long term usage of Primobolan does increase the risk of negative impacts on the liver. There are no liver toxicity risks with the injectable form of Primobolan.
Without water retention, risk of high blood pressure developing when using Primobolan is considered low unless you have an existing condition. Effects on cholesterol are much more of a concern with Primobolan when it comes to cardiovascular health.
It is possible for this steroid to cause a reduction in levels of good cholesterol (HDL) and a raising of bad cholesterol (LDL) levels. Since Primobolan is likely to be used in a cutting cycle that includes cardiovascular exercise and a low fat diet, most people should be able to retain good cholesterol health but this is one area that should be closely monitored throughout your cycle.
Suppression of testosterone is a side effect that can’t be ignored and although Primobolan is once again milder in this regard compared with other steroids, it can still cause enough testosterone suppression at performance enhancing doses that you will want to be using a testosterone compound during your cycle to prevent you falling into a low testosterone state. This is only an issue for men; female users won’t be affected by testosterone suppression when using Primobolan.
Potential liver toxicity is always a concern particularly when using oral steroids, but Primobolan comes with the benefit of not posing a risk to the liver as there are no known cases of liver hepatotoxicity reported for this steroid. However since most people will stack Primobolan with other steroids that may themselves cause hepatotoxicity, it’s vital to be aware of the risks to the liver of each and every compound you’re taking.
Primobolan Post Cycle Therapy
With its milder suppression of testosterone compared to other steroids, recovering from a Primobolan cycle is also easier; but the other compounds you’re using in your cycle are going to heavily determine your hormone recovery and post cycle therapy plan.
When it comes to Primobolan alone, a good PCT plan will speed up recovery and get your natural testosterone production back where it needs to be so you’re maintaining muscle, not putting on fat, and staying in good physical and mental health as a male. Although testosterone will start to rise on its own once you stop taking Primobolan and other steroids, this process is too slow which is why it’s critical to implement PCT.
Clomid or Nolvadex are considered sufficient for Primobolan PCT, with this steroid not requiring the addition of hCG which is often needed for more powerful steroids. However, if your cycle does include more potent anabolic steroids with greater testosterone suppressive effects, then this may warrant the need for a more intensive PCT cycle that does include hCG.
Is Primobolan a testosterone?
Not exactly – Primobolan is based on the dihydrotestosterone hormone, also known simply as DHT. This is an androgen hormone which occurs naturally in the male body through the conversion of testosterone. So while it is similar to testosterone, Primobolan is not derived from or based on the testosterone hormone like many other steroids are.
Is Primobolan legal?
Primobolan is not legal to buy or use without a prescription. As a steroid, it is banned by all sporting bodies as a performance enhancing drug. It is also one of the more difficult and expensive steroids to purchase on the black market or from underground labs.
What are the side effects of Primobolan?
On the plus side Primobolan doesn’t come with the estrogenic side effects so common with many other steroids, like water retention and gyno. But there are other side effects to consider including androgenic ones like acne and hair loss, as well as possible negative changes to cholesterol levels.
What is Primobolan good for?
Primobolan is best used in cutting cycles because of its excellent ability to help you retain your existing muscle. By conserving lean muscle while you’re burning fat, Primobolan acts as an anabolic agent while you’re cutting. It encourages the body to only burn fat while protecting muscle from being burned as energy. As long as your diet is planned and implemented correctly for a cutting phase, Primobolan works as an addition compound in any cutting cycle with minimal side effect risks compared with other steroids.
Can beginners use Primobolan?
Yes, this is one of the best steroids for beginners to start with because of its more mild effects compared with other steroids, and due to the fact the side effects are much less severe and easier to control.
What’s the best Primobolan stack for lean muscle mass and strength?
I’d go with Primo/Deca/Test E/Anavar cycle. This cycle is not cheap, but it’s effective and you’ll keep a lot from it.
- Week 1-12: 200mg/once per week Testosterone Enanthate, 200mg/once per week Deca (load the Test and Deca in the same syringe)
- Week 1-4: 400mg/week Primobolan (twice a week at 200mg per shot, i.e. Monday/Thursday schedule)
- Week 5-12: 600mg/week Primobolan (twice a week at 300mg per shot, if you can’t handle the pain do it 3x week at 200mg), 40-60mg/day Anavar
For recovery wait 2 full weeks after your last test/deca shot and use Clomid at 100mg/day for days 1-10, then 50mg/day for days 11-20.
You can also use HCG. Start right after your cycle at 2500iu/week (2x1250iu shots spread evenly during the week). No need to take AI but if you are prone to gyno, you can use 0.5md/day Arimidex for 3 weeks after your cycle.
Is Primobolan a tablet or injection?
This is one of the few steroids you can use in either oral or injection form. Primobolan Depot is the injection and this only needs to be administered twice weekly, while the tablet is a simple once daily administration.
Where can I buy Primobolan?
Even though this is a popular steroid, it is one of the more difficult ones to locate for purchase. It’s even harder to find high quality, pharmaceutical grade versions of Primobolan and many low quality counterfeits exist.
Because of the difficulty in sourcing quality Primobolan, costs are high compared to most other steroids. It’s not unusual to pay more than $20 for a single dose of Primobolan, making this an expensive addition to a steroid cycle.
My Conclusion and Recommendation
By helping you avoid falling into a catabolic state and losing muscle while cutting, Primobolan really shines as a steroid to use when you’re trying:
- to achieve maximum fat loss without muscle loss
- to achieve a seriously ripped body with the huge bonus of coming with no risk of bloating or other estrogenic side effects
This makes Primobolan sought after by physique competitors and serious bodybuilders.
