SERMs: Nolvadex and Clomid PCT

The question is often asked among the anabolic steroid using community: Clomid or Nolvadex? Which one for PCT?

First of all, the best possible addition to HCG in a PCT protocol is Nolvadex (Tamoxifen Citrate), as studies have demonstrated that HCG and Nolvadex utilized together have exhibited a remarkable synergistic effect in terms of stimulating endogenous Testosterone production, and that Nolvadex will actually work to block the desensitization effect on the Leydig cells of the testes caused by high doses of HCG]. This is very important, because just as too little LH secretion for extended periods can cause desensitization to gonadotropins, too much gonadotropin stimulation (in the form of HCG or otherwise) will likewise cause a desensitization effect.

Secondly, Nolvadex on a mg for mg basis is far more effective than Clomid in stimulating endogenous Testosterone production, as well as being a more cost-effective choice than Clomid itself. Studies have demonstrated that 150mg of Clomid (Clomiphene Citrate) administered daily raised endogenous Testosterone levels of 10 healthy males by approximately 150%, while incidentally, 20mg of Nolvadex (Tamoxifen Citrate) daily raised endogenous Testosterone levels by the same amount. It is very evident here that Clomid is very effective for this purpose, but Nolvadex seems to be a more cost-effective choice seeing as though it is more effective than Clomid when compared mg for mg. The benefits of Nolvadex over Clomid do not end there – Clomid, although it does exhibit Estrogen antagonist effects at the pituitary gland like Nolvadex does, actually exhibits Estrogen agonist effects there too. What this means is that Clomid will actually work in varying degrees as an Estrogen at the pituitary gland, triggering the negative feedback loop and reducing the output of Testosterone stimulating gonadotropins (LH and FSH). This is a very serious problem during post cycle therapy, which is a period in which individuals are trying to recover their HPTA function rather than halt it even further. Ideally, one would want a SERM that exhibits almost 100% Estrogen antagonistic effects on the pituitary gland, and Nolvadex is the perfect choice for this.

When it comes to the dosing aspect of Nolvadex, The standard dose for PCT and for stimulating the release of GnRH (Gonadotropin Releasing Hormone), LH, FSH, and ultimately Testosterone is that of a simple Nolvadex dose of 20 – 40mg daily. In all studies involving Nolvadex doses used to stimulate endogenous Testosterone production, only 20 – 40mg daily of Nolvadex was utilized, and it has in fact been shown that doubling the dose to 40mg or any higher will not produce any significant difference in endogenous Testosterone secretion. The only reason why many elect to utilize 40mg daily of Nolvadex for the first 1-2 weeks of a PCT program is for the purpose of achieving optimal peak blood plasma levels quicker so as to ensure HPTA recovery quicker.
