I'm currently running their mast e at 750mg ew. Love the stuff. I've had other sources mast and sometimes it can be a little thick. AMA's mast is the same consistency as their test. You can expect you libido to shoot through the roof, hard dry muscle, and extreme vascularity. I'm naturally vascular but mast makes it fucking crazy. No issues with hair thinning or anything like that. This is my first run with AMA's mast e and its definitely dosed accurately. Mast e is one of my favorite compounds to add to a cycle. I've had quite a few different sources mast and I'm being completely honest when I say that AMA's is superior in every way.
