I have read a lot about Mag10, but still skeptical, since I have tried several other prohormones w/ little success. I am using 300mg test cyp/week, prescribed for HRT, arimidex, and 75 mg tren ED. I am 54 years old, approx 9% body fat. Will Mag 10 help much? I would like to put on 10lbs (currently 175). Also, should I use Tribex??
