Evidence-based supplements similar to HCG (Human Chorionic Gonadotropin), ranked by shared goals and clinical evidence. Compare any of them head-to-head below.
A racemic selective estrogen receptor modulator (SERM) that has been FDA-approved for decades for female ovulation induction, and is used off-label in men with secondary (low-LH) hypogonadism to raise endogenous testosterone while preserving fertility. By blocking estrogen feedback at the hypothalamus it increases LH and FSH, driving the testes to make more testosterone — unlike testosterone gels/injections, which suppress both. Honest appraisal: clomiphene is the RACEMIC mixture of enclomiphene (trans, the active estrogen-antagonist isomer) and zuclomiphene (cis, a long-lived weakly estrogenic isomer that accumulates) — the zuclomiphene downside is the entire reason the single-isomer enclomiphene was developed. Male use is off-label, the evidence is mostly observational and surrogate-based (testosterone/LH/FSH), and there are NO long-term hard-outcome trials. It is NOT a longevity drug.
The trans-isomer of clomiphene — a selective estrogen receptor modulator (SERM) used off-label/investigationally as a 'fertility-sparing' testosterone therapy. By blocking estrogen feedback at the hypothalamus it raises LH, FSH, and endogenous testosterone while preserving sperm production, unlike exogenous testosterone, which suppresses both. Honest appraisal: Phase-2/3 RCTs show it raises testosterone and keeps sperm counts in the normal range vs topical testosterone — but it is NOT FDA-approved (Androxal failed to gain approval) and is compounded/off-label, and there are NO long-term hard-outcome trials (cardiovascular, bone, mortality).
