There are 2 types of Sarms that have been well studied and work, Ostarine and Andarine.
But you have to understand that the effect is small, it’s not something compared to the anabolic steroid, it does not even come close.
But, on the other hand, it does not inhibit the natural production axis because it is not a steroid. It’s just a molecule that binds to the same receptor.
For those who say do not use steroids, from the moment you use SARMs, you can no longer say that it is natural because you are using something that will generate an effect, so you will no longer be a natural individual.
A pharmacological action already exists to generate an expected hypertrophy reaction. But repeating, it is not an anabolic, because you do not inhibit your own axis.
With that in mind, many people buy SARMs to use it during PCT (post cycle therapy), because during PCT it is recovering its natural production, so it has very low levels of androgenic hormones until it can recover its production.
At that time using Sarms will have an anabolic stimulation of the hypertrophy of the androgenetic receptor, although not as effective as testosterone.
But at least try to minimize the loss of lean mass you’ll always have when you take the exogenous hormone until you recover your own production.
