What Causes Virilization in Females, Specifically?

Question arose after thread posted a few days ago.


The obvious answer is “steroids” but I’m hoping to get into the weeds.

Hypothetically, if one could remove the “Androgenic” from AAS, would pure anabolic activity still cause virilization?

Given the above information, it would make sense that Anavar is such a popular AAS for women to take, as it has very high Myotropic:Androgenic activity. Nandrolone has similar values at index 12-10. So wouldn’t Nandrolone also be a contender for ‘female friendly’ AAS selection? Why or why not?

Back to the original question: AAS = Androgenic Anabolic Steroids. Does Androgenic Activity cause Virilization, or is it Anabolic Activity that does this as well?

IIRC, these values came from a mouse or rat study in which the rodents were given different AAS. The quadriceps were measured before and after as well as the prostate.

If the change in quadriceps was big, it was given a high anabolic or (myotopic) rating, if the change in the prostate was big, it was given a high androgenic rating.

There are a few issues here:

  1. Not generated with humans
  2. Not generated with female rodents
  3. There are undesirable androgenic effects outside of prostate growth.

We know that Mast and Primo have low androgenic ratings, and also lots of men report losing a lot of hair on them. Worse so than Testosterone which has a much higher androgenic rating. Women should expect the same thing as men in that regard. They can often get away with Primo, and not suffer hair loss, because it is usually dosed a lot lower. Primo may be better than Test for other side effects.

Injectable AAS are considered next level for women. It takes longer to clear out, and that makes bailing when sides are noticed take longer to do.
