I know people say not to stay on too long. Well I am not listening. I have been on for about 8 or nine weeks. I just got some sust 250. I really want to try it. I have not been getting alot out of my 500mg cyp. Should I run cyp another couple weeks/ I plan on going pretty heavy with my sust. I just feel like I am not getting anything lately. I did a light cycle before this cycle. 5 weeks. 250mg. no pct. Could my receptors be full. Lots of questions. ANy advice??
