MastoGen Rapid is what is called a finisher. It allows vascularization and makes it "hard", ideal at the end of the treatment to refine the results of your lean or lean mass gain.
As MastoGen is a derivative of dihydrotestosterone (dht), it provides the user with high levels of male hormones. This results in a virilization effect including a dense and durable musculature with little hydro-sodium retention, but without significant mass gain.
This is the reason why this product is used during drying cycles, often in stack (mix) with other “drying” steroids to accentuate this effect. This is how the MastoGen becomes very effective in achieving a scratched look.
This is a very popular steroid for competitors because it disappears quickly from the body without a trace so that it is possible to do a Masteron cycle up to 10 or 12 days before a competition without being detected during a doping control.
MastoGen in its Propionate form is also advantageous for short cycles or for use at the end of a complete cycle. By providing a rapid transition from high blood levels and anabolically efficient to low levels, this will have the effect of a rapid recovery of the natural production of Testosterone after the treatment and thus promote your recovery (PCT).
