Hey haha, I know this is waaaaaay overdue. But do not use it if you are looking to build muscle. It will absolutely kill your numbers. It will drain every bit of fat off of you. Especially if you take 2 pills in the morning. If you do, eat like a horse. If you are getting products from complete nutrition, use natren hgx, ngh-t, and 3-test oxo, and sawzavar. My reasoning for these, is that they have all of the same main products (terrestris and such) in them, but they do not contain any cutters. Hense, you can make the largest muscle gains, reduce estrogen, and balance the fat out with your diet.
