Mastolab-200 – 10ml from 7Lab Pharma, with the main active substance Drostanolone Enanthate, is a special anabolic steroid based on the method of obtaining this drug from dihydrotestosterone (DHT). It has a high androgenic activity, but a small anabolic effect.

This drug is very common in bodybuilding, it is used to give muscles rigidity and shape and is also used as an aromatase inhibitor. Athletes often use this drug at the end of a steroid cycle. Mastolab-200 should always be combined with other steroids so that it can fully perform its work and demonstrate the best results. It is especially effective to combine it with steroids prone to aromatization, such as Dianobol-lab 20 and Testosterone Esters (Testolab-C 250, Testolab-E 250, Sustalab-250). It will not allow water to be retained in your body, and will also be an aromatase inhibitor. Unlike Mastolab-100, this steroid is suitable for longer steroid cycles.

Our customers choose to buy Mastolab-200 for being one of the strongest anti-estrogenic anabolic steroids. This drug not only does not have estrogenic properties, but also acts as an antiestrogen in the body.
