Listen son.
You gotta do your research, you aint wonna end up with some side-effect you cant handle!
All those OTC supplements that are made towards PCT or Cycle support are supplements you would use while still haveing everything on hand!
AI = Aromatise inhbitor, inhibts the aromatise enzyme that converts testosteron to estrogene. But since winstrol cant aromatise you dont need to worry about that
SERM = Selective estrogene receptor modulator, block the receptors so that estrogene cant bind to it and release a signal as Build breast tissue or Bind water "bloat"
its like taking ure own car key and inserting it into another car, it fits but you cant open the car..
PCT:
Nolva is used to boost LH - FSH, also it does help as a SERM because HCG can aromatise alittle. But since aromatiasion happens and once you stop using a SERM estrogene can now bind and give you syndroms or even develop gyno ect. "aka Rebound"
HCG is used to boost the HTPA, but as said HCG can aromatise...
Well we do live in the 2012, and some use drugs that are turning into stone <--- old ****ty drugs for bodybuilding
some OTC products are gold now adays, build towards working and haveing same effects as NOLVA / HCG but not have the unwanted side-effects!
HCG is still gold and a must have
