Maybe with Test Undecanoate or somesuch, but otherwise I start it sooner. If I started 6 weeks after my last dose, I'd feel like sheit and lose some muscle unnecessarily.
That site is good for comparing blood levels of AAS on different dosing protocols though. E4D, E3D, etctera. So, that's cool.
And yes, the site is selling OTC PCT products. It's fine as they have a cool calculator thingy. But also strange, because anyone using AAS has access to and is (hopefully) smart enough to use medical grade PCT products.
I can't see running Test, Tren, and Oral winny and doing PCT with some new
"3-hydrox-ecdysterol-grapeseed-muscle-wasting" Asian plant sterol.
The only OTC AI that's worth a shit when nothing else is available IMO is AIFM.
