I need help! I've been on cypionate since January. After about 8 weeks, I started feeling the effects. Slept better, woke up rested, sex drive increased dramatically as well as erections. My wife and I were having sex every other day. Two weeks ago I had to switch pharmacies. The bottle is different as well as the test. It has stopped working completely. Can't keep erection, starting to feel tired again. Has anyone dealt with this? I am at a loss, I need help!!!
