As far as I’m going to say, you can still be 20, and go on a mild cycle to boost your testosterone levels , and come off of it as healthy (if not healthier) than you were before your cycle. With a proper PCT, taking the precautions of blood tests (cholesterol, ldl, lipids, free test, thyroid, etc), one can still cycle correctly and in a healthy mannor.
I don’t see anything wrong with or feel "immoral" for giving advice on safe cycling. If someone if after advice: give it to them (within reason), and as far as i’m aware: this is within reason.
Hope i have’t broken any rules here, but a nolvadex pct would work fine for this cause. Will also be worthwhile investing in an anti estrogen for safety.
