    testosterone theory


    ive been trying to think of a way to hit all major biological pathways to increase natural test production.

    my theory is that taking nolvadex which would act on the body's negative feedback loop convincing the body that t levels are low, also would counteract estrogen sides if this theory were to actually be effective. Next would be using something along the lines of fadogia agrestis or something similar to further more boost LH and FSH levels. To top it off possibly a nettle root extract to increase free testosterone.

    i figure a stack like this would be nice inbetween cycles to keep gains coming at a quicker pace.

    if anyone has any input on this subject it would be appreciated

    Im not sure why you think it would make the body sense low test levels? Nolvadex competes with estrogen at the receptor site. That means if you arent taking any chemicals except nolvadex, the nolva is going to bind to those receptors....your estrogen will drop, creating a higer test/estrogen ratio, but it wont raise your actual test levels....

    6-oxo instead of nolva would be better, nolva will bring more sides, use it only for pct

    well im not saying that you are wrong, but last time i checked nolva acts as a fake estrogen, and for the body to attempt to maintain homeostasis if it sensed high estro (nolva in this case) it would thus raise test levels to compensate. Isnt that why nolva aids in the recovery of natural t levels when used in pct?

    OK...you are in the ballpark, but nowhere near homeplate....I guess you could say that nolva acts as a fake estrogen ONLY in the sense that it is competing for estrogen receptors...the receptors dont know the difference. Nolva does not aid the body in restoring natural test levels...it is used in PCT because it does exactly what I have stated in this post and the one prior...it competes with estrogen. After a cycle, your natural production is severely suppressed, so if you take nolva, it lessens the sides of estrogen because it basically lowers your estrogen levels...it doesnt raise your test levels. If you didnt take nolva post cycle, your test levels would be in the basement, and your estrogen levels would be sky high...

    nolva can raise T levels but it lowers the IGF-1 hormone among other sides , so as a test booster (out of pct ) an AI will be much better:
    From W. Llewellyn

    Clomid and Nolvadex

    I am not sure how Clomid and Nolvadex became so separated in the minds of bodybuilders. They certainly should not be. Clomid and Nolvadex are both anti-estrogens belonging to the same group of triphenylethylene compounds. They are structurally related and specifically classified as selective estrogen receptor modulators (SERMs) with mixed agonistic and antagonistic properties. This means that in certain tissues they can block the effects of estrogen, by altering the binding capacity of the receptor, while in others they can act as actual estrogens, activating the receptor.

    In men, both of these drugs act as anti-estrogens in their capacity to oppose the negative feedback of estrogens on the hypothalamus and stimulate the heightened release of GnRH (Gonadotropin Releasing Hormone). LH output by the pituitary will be increased as a result, which in turn can increase the level of testosterone by the testes. Both drugs do this, but for some reason bodybuilders persist in thinking that Clomid is the only drug good at stimulating testosterone. What you will find with a little investigation however is that not only is Nolvadex useful for the same purpose, it should actually be the preferred agent of the two.

    Studies conducted in the late 1970's at the University of Ghent in Belgium make clear the advantages of using Nolvadex instead of Clomid for increasing testosterone levels (1). Here, researchers looked the effects of Nolvadex and Clomid on the endocrine profiles of normal men, as well as those suffering from low sperm counts (oligospermia). For our purposes, the results of these drugs on hormonally normal men are obviously the most relevant.

    What was found, just in the early parts of the study, was quite enlightening. Nolvadex, used for 10 days at a dosage of 20mg daily, increased serum testosterone levels to 142% of baseline, which was on par with the effect of 150mg of Clomid daily for the same duration (the testosterone increase was slightly, but not significantly, better for Clomid). We must remember though that this is the effect of three 50mg tablets of Clomid. With the price of both a 50mg Clomid and 20mg Nolvadex typically very similar, we are already seeing a cost vs. results discrepancy forming that strongly favors the Nolvadex side.

    Pituitary Sensitivity to GnRH

    But something more interesting is happening. Researchers were also conducting GnRH stimulation tests before and after various points of treatment with Nolvadex and Clomid, and the two drugs had markedly different results. These tests involved infusing patients with 100mcg of GnRH and measuring the output of pituitary LH in response.

    The focus of this test is to see how sensitive the pituitary is to Gonadotropin Releasing Hormone. The more sensitive the pituitary, the more LH will be released. The tests showed that after ten days of treatment with Nolvadex, pituitary sensitivity to GnRH increased slightly compared to pre-treated values. This is contrast to 10 days of treatment with 150mg Clomid, which was shown to consistently DECREASE pituitary sensitivity to GnRH (more LH was released before treatment).

    As the study with Nolvadex progresses to 6 weeks, pituitary sensitivity to GnRH was significantly higher than pre-treated or 10-day levels. At this point the same 20mg dosage was also raising testosterone and LH levels to an average of 183% and 172% of base values, respectively, which again is measurably higher than what was noted 10 days into therapy. Within 10 days of treatment Clomid is already exerting an effect that is causing the pituitary to become slightly desensitized to GnRH, while prolonged use of Nolvadex serves only to increase pituitary sensitivity to this hormone. That is not to say Clomid won't increase testosterone if taken for the same 6 week time period. Quite the opposite is true. But we are, however, noticing an advantage in Nolvadex.

    The Estrogen Clomid

    The above discrepancies are likely explained by differences in the estrogenic nature of the two compounds. The researchers' clearly support this theory when commenting in their paper, "The difference in response might be attributable to the weak intrinsic estrogenic effect of Clomid, which in this study manifested itself by an increase in transcortin and testosterone/estradiol-binding globulin [SHBG] levels; this increase was not observed after tamoxifen treatment". In reviewing other theories later in the paper, such as interference by increased androgen or estrogen levels, they persist in noting that increases in these hormones were similar with both drug treatments, and state that," €a role of the intrinsic estrogenic activity of Clomid which is practically absent in Tamoxifen seems the most probable explanation".

    Although these two are related anti-estrogens, they appear to act very differently at different sites of action. Nolvadex seems to be strongly anti-estrogenic at both the hypothalamus and pituitary, which is in contrast to Clomid, which although a strong anti-estrogen at the hypothalamus, seems to exhibit weak estrogenic activity at the pituitary. To find further support for this we can look at an in-vitro animal study published in the American Journal of Physiology in February 1981 (2).

    This paper looks at the effects of Clomid and Nolvadex on the GnRH stimulated release of LH from cultured rat pituitary cells. In this paper, it was noted that incubating cells with Clomid had a direct estrogenic effect on cultured pituitary cell sensitivity, exerting a weaker but still significant effect compared to estradiol. Nolvadex on the other hand did not have any significant effect on LH response. Furthermore it mildly blocked the effects of estrogen when both were incubated in the same culture.

    Conclusion

    To summarize the above research succinctly, Nolvadex is the more purely anti-estrogenic of the two drugs, at least where the HPTA (Hypothalamic-Pituitary-Testicular Axis) is concerned. This fact enables Nolvadex to offer the male bodybuilder certain advantages over Clomid.

    This is especially true at times when we are looking to restore a balanced HPTA, and would not want to desensitize the pituitary to GnRH. This could perhaps slow recovery to some extent, as the pituitary would require higher amounts of hypothalamic GnRH in the presence of Clomid in order to get the same level of LH stimulation.

    Nolvadex also seems preferred from long-term use, for those who find anti-estrogens effective enough at raising testosterone levels to warrant using as anabolics. Here Nolvadex would seem to provide a better and more stable increase in testosterone levels, and likely will offer a similar or greater effect than Clomid for considerably less money. The potential rise in SHBG levels with Clomid, supported by other research (3), is also cause for concern, as this might work to allow for comparably less free active testosterone compared to Nolvadex as well.

    Ultimately both drugs are effective anti-estrogens for the prevention of gyno and elevation of endogenous testosterone, however the above research provides enough evidence for me to choose Nolvadex every time.

    In next month's follow-up article I will be discussing the role anti-estrogens play in post-cycle testosterone recovery. Most specifically, I will be detailing what a proper post-cycle ancillary drug program looks like, and explain why anti-estrogens alone are not effective during this window of time

    nunes very informative. this was all stuff that i had previously read about nolva thus me thinking that in the setup i made that would be a serious increase in test although the apparent drop in igf-1 may not be worth it. also i found that using 20 mg per day of my p-plex mdrol and trenx cycle kept my boys in tact for the most part and running through the duration of the 9 week cycle and it seemed completely necessary due to the estrogen sides.
