What is Mast prop?

Mast Prop 100mg 10ml

It stands for masteron propionate or drostanolone propionate.

Drostanolone consists of Dihydrotestosterone (DHT) but is far more anabolic and effective than DHT produced naturally in the body, making things much more pleasant and agreeable. Because it is a pure DHT derivative, it cannot aromatize into estrogen in the body. It will also have anti-estrogen properties. It also increases translation and erythropoiesis in the same manner that all steroids do, but only slightly.
