Currently in week 8 of a test cyp cycle of 400mg a week pinning 200mg twice per week. Other than some mild aggression and very minimal acne all has been well. This past week however I have noticed that my testes have shrunk. Not a huge difference but definitely noticeable. So the advice needed is should I go ahead and start using my HCG and AI that I have for my PCT or just wait out the 4 weeks left in my cycle? Also is there any natural supplement that may help until I'm ready for my PCT?
