At what age is it unsafe to take HGH. If 23, 185 lbs. taking 2 iu's a day, with cyto, clen, test prop, and win. Also Arimidex evrydy. Is this too much, bc after extensive research feel pretty confident, just don't want to over do it. Trying to put on size but mainly lean. (100 iu GenSci Jin kit, prob getting a 2nd one, 40 cc win, 20 cc test prop 100mg, 100 clen, 100 cyto). Help is greatly appreciated.
