I like to use HCG, HMG, SERM (low dose, not that 200mg per day frontload bs floated on the internet), then natty supps in that order. I have a test booster from iron mag labs
that PCT combo works for me everytime. you cannot run high doses of SERM's or you will deal with crappy sides. keep your clomid at 12.5-25mg per day max
if you run tren or deca (heck even test is extremely suppressive and will shut you down severely) or you run a long cycle you need an aggressive PCT. cannot half ass your pct, i work hard for my gains and I damn well don't want to piss it away.
people like me who still cycle know this. too many guys fail with their PCT and then jump on HRT too early in life when its not necessary. I recommend guys who are in their early 20's and have raging libido and test levels abstain from AAS use for this reason till later on. no reason to risk killing your already great libido just for some extra gains, you should enjoy your 20's and have fun with women without worrying about being able to get it up. but hey I am old school
