Masteron. Unless you are prone to hair loss (I’m not), there’s no downside. Upsides include higher free test due to SHBG binding, increased libido, and it just plain makes you feel “good” (that general sense of well being people attribute to certain things like dbol). Think of it as a potentiator, something that makes your test work even better than it would on its own, and you don’t need to run as much either.
As far as 19-nors like deca are concerned, I’d be hesitant to run them year round, but if it works for you (littleslice and others), your bloodwork looks good, and you feel good, then why not, right? I can find a study for anything (water, air, food, sleep, sex, money, women, etc) that says they are good for you, and studies that say the exact opposite. Please no stupid responses about the water, food, air thing, you already know exactly what I’m talking about, and if you bring it up you’re just looking for attention (go find that elsewhere in a “drama thread” lol). I don’t think my body would be happy running deca year round, but then again I can run Tren and get no bad sides at all, no increased aggression, I sleep like a baby, no night sweats, etc, so if I can handle Tren like that, maybe littleslice can run deca year round and feel great.
