I've been using 75mg for the last 2-3 weeks. It's good. The pumps are ridiculous. Vascularity and hardness. It's difficult to say because I'm on a test/mast/tren blend but I'm dosing 100mg the last week week and a half. After I take 50mg (even 25mg) about a couple hours later I get that huge wind where it feels like you're breathing in fresh air on top of a mountain. Strength is up a lot. Compared to other var I've had of high quality this is right up there with them.
