I had acne problems, well zit problems (doesn’t look like regular acne) on the back, shoulders, arms, in all my last PCTs… except this one. It was the first time I took HCG on cycle so it might give us a clue as to why this happens. The zits used to pop up for me off cycle as well, only stopping when I got back on.
Other thing I did different is add iodine supplements on cycle, to help diminish the supposed side effects of Tren on the thyroid. But I suspect HCG was the main reason I had my best PCT ever, and have no zits to speak of this time.
