just wondering what everybodys thought. opinions and experiences with primo are. i finally got my hands on some(shit is so expensive for some reason though) and am gonna be starting it soon with sust250. im gonna run sust250 at 500mg and a week and im still trying to decide how much primo to run. ive got 20ml right now of the 100. i can get more if anyone thinks i need it . looking at a 10 week cycle
