Better than nothing...
Took it after my very first test cycle. Did 12 weeks of test E, followed by 2 weeks of HCG then 4 or 6 weeks of nolva and clomid. Still had zero libido after the PCT lol, hormones were definitly out of whack especially estrogen judging by the acne i got.
Took Arimistane supplement from Blackstone Labs, my libido increased and was able to have sex. When i ran out my libido dropped again and i got painfull nipples. So definitly worked to some degree.
PCT to me is about controlling estrogen while you wait for your hormones to bounce back. If i had to do it again i would run HCG while the gear tapers off then nolva, aromasin and OTC test booster.
