  1. Good product, no negative sides 4 Star Review

    Posted by on 21st Feb 2017

    First time I've done a prohormone cycle, body weight up 11 lbs, max weights up 20%+. Gained 4" on chest 2" on biceps. I'm taking organ shield and have my PCT ready for when I finish. Overall very happy.

  2. Very unique androgen 5 Star Review

    Usually stuff with a high anabolic rating that is 5a-reduced is only good for cutting but this is basically good for anything. stacks well with other PROs or can be used alone.
