Some interesting ideas in this article
and given the fact that as you age it's more difficult to recover from cycling prohormnones/AAS in general it seems might be best to not exceed 4 weeks on(especially if you don't have access to HCG) or add a 1 week stack of pct recovery items for every 4 weeks on.
I wonder if anybody out there has tried the 4/2 theory ?
The idea to use nobotropics to increase sex drive was new to me as well.(CNW sells a product called enlighten that has some of the stuff talked about, in it)
