Primo 100 (10ml)

Primo 100 also known as primobolan is one of those anabolic steroids which has a cult following not unlike the old original version of Masteron. Actually, as you can easily see from its anabolic:androgenic ratio below in the profile, its a pretty weak steroid but actually stronger(!) than Masteron in both regards. I dont know anyone who has run both compounds at the same dose. We are probably justified in speculating that youd probably get similar results from either of them, when you consider the fact that you are getting quite a bit less actual drug and more ester when you choose injectable Primobolan (which has the very long Enanthate ester attached to it) over Masteron (which has the very short propionate ester attached to it).
