I've been feeling great i'm three shots in with my fourth shot tomorrow. Yesterday I got home from work and did not do a damn thing but lay in bed felt like I used to before testosterone replacement therapy (TRT) . Now I am sick I've had a cold for almost two Weeks now but yesterday was the only day that I've felt this way . If I feel the same today i'm gonna call it a crash i'm on test cyp every 7 days with estro blocker
