Wooo! this is one of my favorite subjects!
So, just to rephrase this:
Nolva does NOT stimulate the HPTA directly (it can't right?). It simply blocks the receptor at the pituitary and the breast tissue receptors (amoung others possibly).
The LH and FSH production is due to the secondary effect of Pitutary not detecting the estrogen as it slowly builds up because the receptors are blocked.
Is that correct?
That has been my understanding of Nolva's action, which conflicts with many expert opinions.
If the above is correct, then i don't understand why PCT cannot be done well with an AI like Arimidex to prevent estrogen from building up (as natural Test comes back online) rather than binding to the Pitutary receptors.
Seems like just another way to skin a cat to me. Both prevent the detection of Estrogen, one by preventing Estrogen being created(Arimidex) and the other by hiding the estrogen that is there from the Pituitary..
Perhaps the use of Nolva is some of the reason that some people say they get depressed during PCT - its not that they have no Test, its that they have TOO much Estrogen!
I'm a beliver in prevention is better than cure. Therefore and AI should be better than a SERM for some respects of PCT.
A common argument against Arimidex for PCT is that Estrogen will be low due low Testosterone at the end of cycle so an AI will be ineffective (as there is nothing to arimatize).
But this is the same even if your using Nolva, it can't block what is not there, right?!
As natural Test comes back online the AI will be there to prevent aromatization just as Nolva would be there to block the receptor.
And, if Nolva is NOT stimulating the HPTA directly (it cannot, that's not how SERM or a negative feedback loop works - my understanding) then what's it doing when there is no Test to aromatize? Sweet-fuck-all i imagine..
It seems to me that an AI would work equally well as Nolva, as both achieve the same end result but via different mechanisms.
I concede that AI has less than positive effects on lipid profile(I have read this but haven't looked into it at any length) and from what i have read Nolva has positive effects? Or is this just more internet dogma?
Thoughts? Comments? Abuse?
I just want to learn!
