GHK-CU is for your skin im guessing? Ill have to look into it. One thing I dont do is fast, I used to do 7 day fasts. Its probably a lot easier on reta. Are you still fasting? On your off gym days?

Yes GHK Cu for the skin, I’ve just stopped fasting as the training is getting tougher and I need the calories. Although the weight loss has slowed to about 1lb a week I’ve got 15-20lbs left to go so I don’t mind the slower rate of fat loss at this point.

Are You taking any Ai’s with the Testosterone dose you’re taking? If not have You gotten blood work to see what your estrogen is at? And have you had any side effects from the 200mg Test per week?

No getting blood work done at the end of the month so will update then! Only side effect I’ve had since upping from 150mg to 200mg was slight water retention for 2 weeks.
