MastoGen Rapid is what is called a finisher. It allows vascularization and makes it "hard", ideal at the end of the cure to refine the results of your cutting or lean mass gain.
As MastoGen is a dihydrotestosterone (dht) derivative, it provides the user with high levels of male hormones. This results in a virilization effect including dense and lasting musculature with little hydro-sodic retention, but without significant mass gain. This is why this product is used during cutting cycles, often in a stack (mix) with other drying steroids to accentuate this effect. This is how the MastoGen becomes very effective in achieving a skinned look.
On the other hand it is a steroid very appreciated by competitors because it quickly disappears from the body without leaving traces so that it is possible to follow a treatment with Masteron up to 10 or 12 days before a competition without this can be spotted during a doping control.
MastoGen in its Propionate form is also advantageous for short cycles or for use at the end of a full cycle.By providing a rapid transition between high and anabolically effective blood levels towards low levels, this will have the effect of a rapid recovery of the natural production of Testosterone after the cure and thus promote your recovery (PCT).
