Primobolan Side Effects

Primobolan is an anabolic steroid that was derived from dihydrotestosterone (DHT). The compound is also known as the name Methenolone, the active substance. Therefore, you can find Methenolone as other brands, yet Primobolan remains by far the most popular one.

Like most other steroids, it was made for therapeutic purposes. But people searching for physique improvement and performance enhancement discovered it highly effective for their needs. Later it was discontinued for medical purposes due to the availability of other alternatives. But it still remains popular in the sports and bodybuilding scene.


The anabolic steroid is having a much lower anabolic and androgenic activity compared to most other steroids. Therefore, Primo is considered much milder. While it cannot offer huge muscle mass growth as other steroids would, it makes it have a significantly lower risk of adverse side effects.

Therefore, compared to other anabolic agents, Primobolan is a much safer alternative. Generally, we can’t call anabolic steroids safe due to their nature. However, Primo is an exception because of its mildness. Although is still capable to cause side effects, they are mostly reported only in case of abuse. Therefore, Primobolan is seen as a great option among those athletes and bodybuilders who want to reap the benefits of the anabolic agents without harsh side effects.

But then again, please be aware that Primobolan is not entirely safe. It just has a mild nature making it slightly safer compared to others.


What are Primobolan Side Effects?

Despite the fact that is not as aggressive in terms of side effects as Trenbolone or Winstrol, for example (other cutting steroids), Primobolan (Methenolone) has its own set of side effects. They can get serious in case you wouldn’t take caution and use it correctly.


Primobolan Side Effects Androgenic

For example, Methenolone, like any other steroid, possesses androgenic activity. While it is lower and milder, androgen related side effects are likely to occur. Especially to people genetically predisposed to them. For example:

  • Male pattern baldness
  • Oily skin
  • Acne
  • Increased aggression

Cardiovascular and Cholesterol Primobolan Side Effects

Except for that, Primobolan is also capable of negatively affecting your cholesterol values. This may lead to some cardiovascular issues. That’s especially if you’re already suffering from such issues or are at high risk of developing them. We recommend avoiding Primobolan (and any steroid) if you are predisposed or already suffer from cholesterol or cardiovascular problems.

Endogenous Testosteroneprimobolan-side-effects-in-men-bodybuilding

Except for that, one more side effect that is common among all anabolic steroids is the inhibition of endogenous testosterone. Also known as suppression of natural testosterone production. Then again, Primobolan has a mild profile and that’s why the suppression rate is reduced compared to other steroids. It might not be a huge problem if used in low or medium doses.

Nonetheless, your testosterone levels are still going to be affected anyway. Especially because Primobolan is usually stacked with other anabolic steroids. And commonly, those steroids affect it way worse. Therefore, a PCT plan is still very important after each cycle. But if you run Primobolan with milder steroids in lower doses and shorter cycles, you may not need a harsh Post Cycle Therapy (PCT) plan.

Primobolan Estrogenic Side Effects

Methenolone is a DHT derived steroid that doesn’t aromatize. It doesn’t increase estrogen levels. Therefore, side effects such as gynecomastia and fluid retention won’t occur with Methenolone. In fact, it can work as an anti-estrogen in some cases.

Nonetheless, such issues can still occur if highly aromatizing steroids are paired with Primo, especially in high doses.


The mildness of Primobolan is making it a very attractive steroid for female athletes. Since is one of the mildest androgenic steroids, women use Primobolan for their fitness goals too. However, it still has an androgenic activity which means that virilizing effects in women can still occur from the use of Primo. Some examples are:

  • Facial and bodily hair growth
  • Hoarsened voice
  • Clitoral enlargement
  • Menstrual irregularities
  • Shredding hair
  • Reduced breast size

Women are highly advised to use low doses for short periods to avoid them. Doses and cycle lengths are much lower/shorter than those men can run. Plus, women are only recommended oral Primobolan due to its much shorter half-life compared to that of injectable. If the side effects start to occur, they can discontinue the use, and Methenolone is quickly flushed out of the system.
