no one introduces exogenous cortisol (or any other hormone) as part of their PCT (as far as i know). The common practice is to "block" it during PCT actually.QUOTE]
If only it was that straight forward... cortisol was just an example of a hormone that isn't anabolic... anyway what do you think nolvadex is exactly ?? I'm not some really smart dude and i'm not meaning to talk down to you or anything but i like to think i have some common sense and a certain amount of undersanding which can be can applied it in any given situation so i still stand by my initial comments and this is what i've come up with to back it up....
Tamoxifen (nolvadex) acts as both an antaganist and AGONIST. If you don't know what an agonist is it means it actually mimics estrogen therefore it kinda is synthetic exogenous estrogen ... oh and the next bit i ripped from wikipedia....
Tamoxifen itself is a prodrug, having relatively little affinity for its target protein, the estrogen receptor. It is metabolized in the liver by the cytochrome P450 isoform CYP2D6 and CYP3A4 into active metabolites such as 4-hydroxytamoxifen and N-desmethyl-4-hydroxytamoxifen (endoxifen)[20] which have 30-100 times more affinity with the estrogen receptor than tamoxifen itself. :thumbsup:
So technically speaking tamoxifen already is a pro hormone since it acts as an estrogen in certain parts of the body. Not only does it bind to estrogen receptors and act like estrgen in certian tissue it also has to convert in the liver to different substances with higher affinity to the estrogen receptor for it to be effective...
meh. i dunno. just never seen nolva/clomid/torem ever referred to as a "PH." good job on the research tho.
all i know is my opinion on the subject of this thread is that if you want something like nolva, it's probably better just to get nolva.
