]Thanks for the response, really, it's very much appreciated.
I've got one more question (probably only one
I perceive the above regiment as fairly light, i.e., 30-50mg Dbol + 50-100mg Tren A ED; would the following work, and does it really need to be run for two weeks considering the light AAS use?
Front-load: Clomid: 100mg + Nolvadex 40mg
6 Days: Clomid: 50mg + Nolvadex 10mg
7 days: Clomid: 25mg + Nolvadex 5mg
Thanks again,
Rey
According to what?Having only antiestrogenic activity perhaps may not give optimum effect, as estrogen can actually result in better responsiveness to LHRH,
Progesterone, acting synergistically with oestrogens, exerts negative feedback on the hypothalamus during the luteal phase, thus limiting GnRH pulsatility and slowing LH pulse frequency. The mechanism of positive oestrogen feedback at the time of the LH surge has been much debated. There is now evidence that enhancement of both hypothalamic GnRH pulse generator activity and pituitary responsiveness to GnRH are involved. All species so far studied have shown an increased 'self-priming' effect of GnRH on the pituitary during the preovulatory period...
In males, the situation is more straightforward. Since LH surges do not occur, only negative feedback effects are relevant. Testosterone (and its active metabolite dihydrotestosterone, DHT) exerts major suppressive effects on both LH and FSH secretion, largely by inhibiting the GnRH pulse frequency generator, but possibly also by direct pituitary actions. Oestrogens in the male reduce pituitary responsiveness to GnRH.
According to what?
You're talking about estrogen priming here: the concept that estrogen makes the pituitary more sensitive to LHRH (also called GnRH) from the hypothalamus, so that more LH is released for a given GnRH stimulus. This is well known to occur in females leading up to ovulation. Unlike females, however, men don't have a preovulatory period or spikes in LH. The research is fairly clear that estrogen priming does not occur in males. First, look an authoritative reference work like Grossman's Clinical Endocrinology, which states (pg. 99):
That states pretty clearly that in males, estrogen produces negative feedback, not priming. The last sentence in bold directly contradicts the notion. If clomid were to produce estrogenic action in the pituitary, it would serve to inhibit LH secretion.
Grossman's statement is corroborated by the most recent research on the specific effects of androgens and estrogen on the pituitary and hypothalamus of healthy men. Here, it was shown that estrogenic action at the pituitary has an inhibitory effect on LH output. In other words, estrogen decreases pituitary sensitivity to GnRH. Estrogen does not produce positive feedback as seen in estrogen priming in females. The paper stated in its conclusion that "These data confirm previous work from our group which ... showed [estrogen] has both hypothalamic and pituitary sites of negative feedback in the male." In fact, "negative feedback at the pituitary requires aromatization," as testosterone itself doesn't produce negative feedback at the pituitary.
Finally, there's this study, which couldn't have been any more relevant. There, the effect of nolva and clomid on the pituitary of human males was directly examined. They infused the men with 100 mcg of GnRH and then measured LH output from the pituitary. The men taking nolvadex at 20mg/day had a significantly increased LH response to GnRH. In contrast, the men taking clomid had reduced LH output, a decreased sensitivity to GnRH. The researchers stated that "a role of the intrinsic estrogenic activity of Clomid which is practically absent in Tamoxifen seems the most probable explanation."
All in all, I don't see what basis Bill has for the claim that estrogenic activity from clomid "can actually result in better responsiveness to LHRH." This assumes estrogen priming in males, yet both direct research and experts in endocrinology seem to squarely contradict the notion. Clomid appears to produce an estrogenic effect at the pituitary, yes, but the evidence shows that in males this serves to inhibit LH output, in contrast to nolva. All else being equal, that would make the use of clomid inferior to nolva for purposes of PCT.
If what we know is that estrogen priming "does not" occur in males, then why would you suggest that it "can" occur in males? It couldn't be more misleading to say that "estrogen can actually result in better responsiveness to LHRH" when we're not talking about females and when the evidence in males shows the opposite effect occurs.When I say "does result" or "must result" or "always results in" the meaning is different than when I say "can" result.
The question of whether nolva or clomid is better for overall recovery is distinct from the question of which is better at the level of the pituitary. I've addressed nothing but your statement on the latter.I don't think that the studies you cite, or any studies, demonstrate that Clomid cannot give a better result, due to this pharmacological difference, than Nolvadex for male bb'ers. I actually rather suspect you'd agree they don't prove any such thing.
No response Bill?OK. So let me get this straight. The effects of clomid and nolva on the pituitary of normal males "doesn't even make the first beginning at addressing the issue" of the effects in recovering males? Not even the first beginning. Yet female physiology does? Please explain, how does normal female physiology begin to address the question any better than normal male physiology? Alternatively, if you want to argue that both are completely and utterly irrelevant, then why would you imply either, or in this case, estrogen priming (i.e. the female physiology)?
I think it's ridiculous to say that both are completely and utterly irrelevant. I also think it's ridiculous to take the position that normal male physiology is less relevant to the question than normal female physiology. Accordingly, why would you imply the female physiology and estrogen priming?
Nandrolone phenypropionate is unproven in this application and I think would be a poor choice as recovery problems are common with nandrolone.
