May 1, 2018 Hey. was wondering if someone could help me out. I wanted to order something this week but have been stuck between a few things. Has anyone heard or used anything from flexx labs? if so how were the results? I was thinking of getting the extreme stack from flexx labs and adding in Dianagen XX with it. Then I got stuck between cardarine wondering if it would work any better. My plan is to gain as much muscle mass as possible and basically get as big as I can without adding on a bunch of fat, I'd like to have my abs show and be a bit shredded. I'm 18 about 160lb been working out for about 2 years naturally but have really seen no results but some strength. Please help me out, it'd be greatly appreciated. Thanks!
