I am over 50 yrs old and want to try a GH. I am in great shape. Can someone recommend what to take for first timer Have 30+years experience in the gym. I stay in the gym 4-5 days a week. In the 70's and early 80's tried to go pro, so did some cycles under DR's scripts. (test) I have some back issues along with cervical disc problems and think that building muscle around these problem areas will help. I take a drug that has acetaminophen in it and want to try to get off this for my liver.. I am looking at 1-ANDRO Rx but I am not sure if this is good. I did order ANABOLIC-MATRIX Rx and am starting that.
