I'm looking for some more information on this. I know my SO has used testosterone injections in the past. Can anyone tell me the after effects of the cycle. I know he has done them a couple times throughout the years. When he was younger he was much easier to be around honestly. Better mood, higher sex drive. Now that he is middle aged I feel like his attitude is kinda snappish. Sex drive is meh. He doesnt know that I know. He thinks I only know about the one time when he was younger. Yeah I flipped my **** when I found out. Like obviously very concerned for his health but I'm not really looking into the why I'm not upset part. Just want to chat with someone that can give me details on what might be going through his mind. Trying to better understand. He absolutely will not be forthcoming, and I honestly dont want to argue and fight. Can anybody out here help me out??? Also sex drive always high during a cycle like if he's not ****ing me do I need to consider that he's ****ing somebody else.
