Masteron is what is called a finisher. It allows the vascularisation and makes it “hard”, ideal for the end of a treatment to refine the results of your lean mass gain or slimming.
As Masteron is a derivative of dihydrotestosterone (DHT), it provides the user with a high level of male hormones. This results in an effect virilization including a dense and durable musculature with little fluid retention, but without significant mass gain. This is why this product is used during slimming cycles, often in stack (mix) with other “slimmer” steroids to enhance this effect. Thus Masteron is very effective to get an écorché look.
