Primobolan – Guide A-Z

What is primobolan? What are the benefits of this steroid? Does it have any side effects? What results can you expect from this product? Where to buy primobolan? These and other questions are answered in the following article.

What is primobolan depot?

Primobolan depot is an injectable form of Methenolone. It is one of the gentlest anabolic steroid for the body. It is a derivative of DHT, but has no strong androgenic effects. Despite its price and the fact that it does not give huge muscle gains, it is relatively popular. This is due to the fact that Primobolan has practically no side effects. It is ideal for beginners, women and people who are afraid of hair loss or gynecomastia.


primobolan enanthate

Half-life: 4.5 days

Content of the substance in a chemical compound: 70%

The most popular form of methenolone. It usually comes in a concentration of 100mg/ml. Due to the long half-life the injections should be done 2x a week. PCT should start about 2 weeks after the end of the cycle.

primobolan acetate

Half life: 1 day


Content of the substance in a chemical compound: 83.4%

Not very popular form of methanolon, mainly due to its low concentration – 50mg/ml. Due to the short half-life, the injections must be made daily. PCT should start 3-4 days after the end of the cycle.

Primobolan tablets

Methenolone is also available in tablet form. It does not have a 17CAA group, so it is not as hepatotoxic as other steroids. However, it does put some strain on the liver, so it should not be used in this form for more than 10 weeks.

Methenolone in tablets is in the form of Acetate, which makes it necessary to take it several times a day to maintain a stable concentration in the blood.

When choosing a dose, remember that oral steroids pass through the liver twice. This results in greater elimination of the agents by the liver. As a result, the form in tablets has about 60-70% of the strength of the same injectable steroid (counting 1mg : 1mg).


Increased strength – Primobolan, like other DHT derivatives, significantly increases strength. This allows for heavier workouts and thus easier muscle mass gain.

Muscle mass gain – With methenolone you will not see a drastic increase in mass as with testosterone, dianabol or other “wet steroids”. Primo increases weight gradually, but gained weight is of much better quality and remains practically 100% after the cycle.

Fat loss – In fact, Primobolan itself does not accelerate fat loss, but it is very helpful during weight reduction. It preserves most of the gained muscles and increases strength. Due to the fact that it is a derivative of DHT, it also allows to achieve a dry, aesthetic silhouette observed in models.

Libido growth – Although a very small percentage of primo binds to androgenic receptors, the binding force is very strong. This results, among other things, in an increase in libido. However, this effect is not as strong as in the case of strongly androgenic steroids such as trenbolone.
In a few cases methenolone can lower the libido – this is due to the fact that it has a slight anti-estrogenic effect. For this reason it should be used in combination with steroids that convert to estrogen.

Better mood – Methenolone is known to improve your mood. It is not as strong as Dianabol, but definitely noticeable. It increases self-confidence and decision-making skills, as well as the amount of energy during the days and during training.

Side effects

Methenolone is one of the safest steroids. It is very mild to the body and causes practically no side effects, so many people decide to use it even for several months.

Also taken orally in tablet form, it does not burden the liver as much as other oral steroids (but it is to some extent hepatotoxic, so you should not take large doses for a long period of time without liver protective drugs).

Like all steroids, it blocks the HPTA axis, so PCT is necessary after the cycle is completed.

Is Primobolan hair loss safe?

Although Primobolan is a derivative of the 1-test, it is safe for hair and can be used by people with hair loss problems. Of course, as with every steroid, there is a risk of accelerated hair loss, but it is minimal.

Unfortunately, a big problem is that primobolan, due to its very high production price, is one of the most frequently counterfeited steroids. Very often masteron is actually sold instead of primo, which strongly accelerates hair loss. For this reason, Primo should only be purchased from trusted sources.

Primobolan for women

primobolan women

Methenolone can be used by women even for several weeks without any side effects. Even though it is a weakly adrogenic agent, it should not be used in excessive doses. The optimal dose for the first cycle for women is 50mg/day.

The maximum dose that women can use for a longer period without fear of side effects is 100mg/day.

Primobolan solo

Using only primobolan is not a good idea. Methenolone does not aromatize and is even weak AI, which means that after a few weeks you will have problems with too low estradiol levels. It is also quite a weak androgen, so although it often increases libido in combination with other substances, a strong decline can be expected in this case.

Primo should always be used (except for very low doses in women) in combination with another steroid that produces estradiol such as testosterone, dbol or nandrolone.


Primobolan is a relatively weak anabolic, so using it at doses of less than 300mg/week for less than 10 weeks in my opinion makes no sense.

I think a good dose for the first cycle is ~400 mg/week in combination with >500 mg/week of testosterone.

It is very mild to the body and at standard doses there are practically no side effects. For this reason, it can be used even at doses of >1g/week if your budget allows it.


primobolan results

Primobolan is one of my favorite steroids. You can add it to virtually any stack and it’ll do great. It gives extra growth and reduces water retention without increasing possible side effects.

The results of Primo (1mg : 1mg) are very similar to NPP (Nandrolone). And the effects themselves are practically identical to masteron. Unlike masteron, it has practically no side effects. It also does not block the HPTA axis so strongly, so PCT is usually not a problem.

Cycle example

1-10 week:Primobolane200mg every 3.5 day
Testosterone cypionate250mg every 3.5 day
11-12 week:NOTHING
13-16 week:Clomid50mg daily
Nolvadex20mg daily

This is the optimal first cycle in my opinion involving methenolone. It provides noticeably larger gains than a cycle using only testosterone. An additional advantage is the fact that methenolone lowers estradiol levels, so in most cases, in such doses you will not need to use Aromatase Inhibitors.

Since primobolan is free of side effects, its dosage can be increased without fear, which will certainly translate into higher muscle mass gains. However, from an economic perspective, given the high price of methenolone, I believe that the doses proposed above are optimal.

When using anabolic steroids, the body detects super physiological doses of androgens in the body and stops their endogenous production. When the cycle is complete, the body needs several weeks to restore their production to normal levels. During this time, typical symptoms of testosterone deficiency are observed: loss of muscle mass, weak libido, depression. To prevent them, PCT (clomid and nolvadex) drugs should be used to increase LH and FSH production and thus increase testosterone production.

PCT should start about 2 weeks after the last injection. Clomid and nolvadex should be used at a combined dose of 50mg/day and 20mg/day respectively for about 4 weeks.

Where to buy primobolan online?

Unfortunately, most of the shops selling steroids online turn out to be scammers and after you transfer the money you will never get your goods. They take advantage of the fact that such scams cannot be reported to the police for obvious reasons.
An equally common problem is lowering product concentrations or selling completely different substances than those declared on the label. This is a particularly serious problem with Primobolan, which is very expensive to produce. I estimate that about 80% of the products sold as Primo contain other substances – masteron or prop test. This is a very dangerous situation, because when side effects occur it is often difficult to locate their cause.

For this reason, steroids should only be purchased from trusted sources, preferably from people you know and trust.

For people who don’t have this type of contacts, below are the stores that I have used and can recommend:


Prestige pharma

One of the first online steroid stores I’ve ever used. It used to exist on the .com domain, however, after the trouble with the law it suspended its activity for a few years. A huge advantage of this store is the fact that a large part of the offered drugs (AI, PCT, cabaser) are original medicines from pharmacies, and the steroids available in the offer come from the biggest European manufacturers. I personally tested Omega primobolan and I can strongly recommend it.

EDIT: After contacting the shop owner I managed to get a discount for blog readers: RICHARDJ10

One of the most popular stores selling steroids in the world. I used them many times, mainly because of the competitive price and I was usually satisfied. Recently they have changed the layout and product names, which makes shopping less intuitive (I’m not sure if only the names of the agents or their manufacturers have changed). I have never bought primobolon from them, so I cannot comment on its quality.

I must praise the store’s service, which is very helpful and willing to give discounts. It is also worth mentioning that when ordering several identical products, additional discounts are automatically calculated.
