In this article, you would find a summarized information about everything you need to know about Primobolan and first off is important to find out:

What is Primobolan?

There’s a high chance that you have heard about Primobolan taken in consideration that this is a very famous anabolic and androgenic steroid (AAS) for physique and performance enhancement purposes, but you may have heard about it as Methenolone (the active substance) or shorty as many people often call it – Primo.

The steroid has been derived from dihydrotestosterone (DHT) as many other famous steroids and this one is available in both injectable as well as oral form of pills. Some people choose the injections, other choose the oral pills due to a number of reasons. Based on what you need and what is better for you, you can choose either injection or pills of Methenolone (sold as Primobolan).

The compound has been firstly in USA many years ago in 1960s and back then, it had various different medical purposes. However, mainly, the effects of Methenolone were studies in treatment of breast cancer so it was mainly used for this purpose.

However, a few years later, Methenolone got discontinued from being used in medical settings in most countries so you won’t see it being given to people with medical conditions (mainly because of availability of other options).

But instead, Primobolan is very widely used among bodybuilders and athletes in order to help them enhance the physical performance, physical appearance and generally increasing muscle mass and muscle hardening effects.

So well, as mentioned, Primobolan is coming as injection and as tablets, that’s why there are 2 variants of Primo that you can choose from. Before you decide which is better for you, is highly recommended for you to carefully read about them and learn what you can expect from each.

Methenolone Enanthate – Injectable Primobolan

Injectable Primobolan is having the same active substance and orally active one, with the exception of Enanthate attached ester. The injectable version is coming as Methenolone Enanthate and this is considered a long lasting ester – much longer compared to the oral pills version of Primo.

The biggest difference between injection and oral is in the half life. Methenolone Enanthate is having a long half life of about 7-10 days.

Is important for you to remember that regardless of which version you would choose, the main substance remains the same – Methenolone, which is a steroid that got derived from dihydrotestosterone (DHT) and as all other DHT derived steroids – it cannot aromatize. Without aromatization, the compound won’t convert into estrogen and therefore, no estrogen related side effects like Gynecomastia would occur with Methenolone.

Methenolone Acetate – Oral Primobolan Pills

The oral Primobolan pills also contain Methenolone, as mentioned, however is coming as Methenolone Acetate. When referring to Methenolone Acetate, you’re actually referring to oral Primobolan.

As said earlier, the steroid coming in form as oral pills is having a much shorter half life compared to the injectable Primobolan. That’s because the half life of Methenolone Acetate (oral Primo) is only about 4-6 hours.

A very interesting fact that should be mentioned here is: Methenolone Acetate (Primobolan tablets) is the only orally active steroid that is not C17 alpha alkylated.

17 alpha alkylation is what usually allows the steroids to be orally active – to survive through the liver. But that’s toxic to the liver. Methenolone Acetate, however, without being 17 alpha alkylated is still surviving the liver having a high effectiveness.

As a result, Primobolan is considered to be a lot much less toxic for the liver compared to all other orally active steroids like for example Dianabol, Anadrol, Winstrol, Superdrol and others.

The only problem here is that Primobolan is considered to have a pretty weak bioavailability. At least weaker compared to other steroids. Therefore, is quite obvious that Primo is going to be weaker compared to other steroids too.

Primobolan Effects

Primobolan that is very often shortly called by most people Primo – is a steroid that is most often used during the cutting and hardening cycles, or as a steroid for preparation before a contest or show, and that’s regardless in which form you use it. That’s because the steroid is going to be amazing for offering great muscle hardening effect while you are getting shredded.

However, due to its considerably lower anabolic and androgenic activity compared to other steroids, this steroid is not really good for building muscle mass. While it may help you to add some lean muscles, the gains would be far compared to other options available.

That’s the reason why if you’re searching specifically for gaining as much size and muscles as possible, Primobolan won’t be too helpful for you, so bodybuilders are going to use such steroids like for example Anadrol, Deca Durabolin, Dianabol and others for building as much muscles and size as possible. Instead, after bulking, here’s what you may get with Primo:


This is one of the reasons why a lot of people are underestimating the effects of Primobolan and we think that this is a big mistake. Other than the fact that Primo is not very suitable for helping to grow muscles as big as possible, Primo on its own alone is not that powerful either. Many people are comparing Primobolan with Masteron when it comes to their potency and strength.

As a result, a lot of people greatly underestimate the effects of Primobolan but that’s a big mistake because this steroid still can be extremely helpful with unique results. Primobolan tends to show its full potential which is really big when is being stacked (combined) with other steroids. That’s why, we highly recommend you to use Primo in combination with other AAS only, if you want to get full efficiency.

Indeed, Primobolan is a lot much weaker when compared to Trenbolone so you shouldn’t expect it to work in the same way – you just can’t compare the strength of Trenbolone to Primo. Nonetheless, Methenolone is still having its own set of effects and benefits that are super helpful for physique and performance enhancement purposes.

The steroid is mostly known for its muscle hardening effects that are great. With a proper use of Primobolan, you are going to appear much fuller, muscles much defined and overall harder. That’s the main reason what makes Primo so famous and widely used, but except for that – those using Primobolan also report amazing increase in vascularity, increase in strength levels as well as it helps with fat loss processes too.

It was noticed that Primo is going to be amazing at speeding up the muscle recovery processes either – an extremely important and valuable effect by anyone who is looking for physique and performance enhancement.

Primobolan Cycles & Primobolan Dosages

According to most people who are using Primobolan, they seem to love the injectable Primo more compared to orals. That’s one of the very few steroids where the injectable version seem to be more favorable compared to orals.

Nonetheless, there are still a lot of people who love oral pills of Primobolan, that’s why, decide which one you want and start using it properly.

  • Well, most bodybuilders and athletes who prefer Methenolone Enanthate (Primobolan injection) they seem to prefer the dosage of anywhere around 400 mg per week. You could take more or less based on how well you can tolerate it and what are the expected results.

A cycle with Methenolone Enanthate, according to most people with experience on this steroid, suggest that is anywhere between 8 weeks and 10 weeks for staying healthy and still receiving amazing effects.


Is important to keep in mind that Methenolone Enathate, due to Enanthate attached ester, has a very long half life, therefore, administering only twice per week would maintain stable blood levels and offer the desired results.

For example, if you go for 400 mg per week, then you could administer 200 mg on Monday and 200 mg on Thursday, for example.

  • However, if you’re searching for an oral form of Primobolan to simply swallow tablets making the administration easier – you would be required to use a dosage of anywhere around 150 mg per day.

But because of the fact that Methenolone Acetate has a much shorter half life compared to the injectable version, you would need to administer the pills at least 2 times per day. Some people use it 3 times a day. Split the total daily dosage into even doses that you want to take throughout the day.

Cycle length with Methenolone Acetate is also in the range of 8-10 weeks, but most people stop at 8 weeks with oral Methenolone (Primo) and even at 6 weeks.

You could start with a lower dosage and then increase it if you feel that you need more. There are some bodybuilders that are reporting using Primo at doses higher than 150 mg a day, however, that’s not recommended.

  • As it was earlier mentioned – all Primobolan cycles (regardless if you use oral Primo or injectable version) should be stacked with other steroids. Using it alone won’t offer too big results, but it comes in full potency when combined with others.

Very often is being stacked with testosterone base steroids like for example Sustanon, but it could be any esterified testosterone such as Testosterone Propionate, Testosterone Enanthate, Testosterone Cypionate or whatever other.

Taken in consideration that the steroid is very rarely used in bulking cycles but is mostly used in cutting and hardening cycles, is often also stacked with cutting steroids too, it could include Winstrol (Stanozolol), Trenbolone, Anavar (Oxandrolone) and others.

Keep in mind that Primo might be considered a weaker steroid, but is still extremely effective offering huge results. In the same time, it could become dangerous if using it incorrectly. You need to respect Primobolan for offering great benefits and for being capable to offer nasty side effects too.

If there are still people who are in doubt about Primobolan’s efficiency then Arnold Schwarzenegger might change your mind. That’s right – the bodybuilding legend Arnie used to administer Primobolan in order to get in his best shape during his prime.


A proper use of Primobolan stacked with other steroids, with a proper diet and workout regimen, might offer incredible results, results that ol’ Arnie achieved for becoming the most famous bodybuilder on the planet.

Primobolan For Women

Mainly because of the fact that Primobolan is a very famous mild steroid, a lot of women also experiment with it. In fact, Primo is considered to be among the most popular and widely used steroids for female bodybuilders.

Anavar is considered absolutely the most famous steroid for women, nonetheless, Primo does seem to be right after it. The reason why these steroids are so famous for women is because they are much milder compared to almost all other steroids that are having a lot of side effects.

Despite the fact that both Primo and Anavar still carry side effects – the risks and their intensity can’t be compared to those of Trenbolone – a compound so strong that is not recommended for women at all.

Primobolan for women should be taken in lower dosages and in shorter cycles compared to men because it would still be enough to offer great results. Although some women go for injectable version of Primobolan (Methenolone Enanthate), is highly recommended for women to opt for oral version of Primobolan (Methenolone Acetate).

That’s because in case something goes wrong – the steroid is much faster flushed from your system. Women need to watch out for the virilization symptoms. They need to discontinue the use of Primo at the appearance of first virilizing signs in order to avoid getting them worse and permanent.

With oral Primo – the steroid is flushed fast, but with injectable – it would remain much longer, increasing the risks of side effects.

The cycle length is anywhere between 4-6 weeks and the dosage is anywhere between 10 up to 20 mg a day. Higher dosages greatly increase the risks of side effects for women.


Primobolan Side Effects

By reading this article until this moment you most likely realized that despite the fact that Primobolan is not as a powerful steroid as most other steroids are, it does offer some negative side effects, however, they are much less likely to occur compared to other steroids taken in consideration that the steroid is much milder.

Is very important to use Primobolan properly – do not abuse it by not taking too high doses or for way too much time and you’re most likely going to be alright. The steroid is much less likely to offer you negative side effects.

Is important to know that Primo is a DHT derived steroid and as with all other DHT derived steroids – androgenic side effects such as hair loss, acne, oily skin, aggression and others are possible to occur.

In addition to that, as any given steroid out there – using Methenolone would result in testosterone suppression. According to many people, the suppression is so low that using a Post Cycle Therapy (PCT) at the end of the cycle is not required. That’s completely false as a PCT is an absolute need in all steroid cycles endings.

So, you can expect testosterone suppression and androgen related side effects in most cases. They can be very well tolerated in most cases and controlled, but you still need to watch out.

Virilizing side effects for women are other very possible side effects.

At least, with Primobolan, no estrogen related side effects would occur since it cannot aromatize.

Milder means safer, but doesn’t mean absolutely safe and that’s why a PCT plan, cycle supporting supplements and a proper administration are all very recommended. In case you do notice side effects with Primo, we highly recommend to reduce your dosage.

Primobolan In Conclusion

Primobolan is an extremely popular steroid, which can be used either as injection (Methenolone Enanthate) or as oral pills (Methenolone Acetate).

Due to its mildness but high effectiveness, the steroid is widely used by many bodybuilders as well as by women using steroids. Injection Primo being favorite by men and oral Primo pills favorite by women.

The compound is not very helpful during bulking and is not super effective when used alone. Nonetheless, a stack made with Primobolan and other steroids during the cutting and hardening cycles would offer mind blowing results.

It is a big mistake to underestimate Primobolan – it can be dangerous if not used properly and in the same time, a correct use of Primo can offering extremely big results and benefits.

Just make sure to buy Primo from trustworthy and reliable sources because you need real and high quality Methenolone if you want to get actual results. Use and you are ensured to buy Primobolan products of best quality (regardless oral or injectable) for the best prices.
