   Why these numbers? ▾

   Effect size: In a 12-week RCT on Physta 300 mg, men reported higher libido and sexual well-being alongside more free testosterone (Ismail 2012); in 76 men with late-onset hypogonadism, 200 mg/day moved 90% into the normal T range within a month (Tambi 2012). A real, felt effect — 7.8/10, not higher because the trials are in stressed or hypogonadal men.

   Evidence: A 2022 systematic review and meta-analysis of clinical trials confirms the testosterone rise; the libido endpoint has fewer, smaller trials behind it. 8.4/10.

   Reliability: Works in the men most likely to be reading this — stressed, over 40, low-normal T — and less in young men with nothing to correct. Standardisation (LJ100 / ≥2% eurycomanone) decides whether you get the trial dose. 7.6/10.

   Why these numbers? ▾

   Effect size: Twenty weeks of dietary zinc restriction cut serum T in young men; ~30 mg/day for six months restored it in deficient older men (Prasad 1996). Libido follows testosterone here, so the effect is real — but only up to normal. 5.8/10.

   Evidence: A depletion-repletion experiment plus a cross-section where cellular zinc tracked T; no libido-specific RCT in replete men. 7.8/10.

   Reliability: Only deficient men respond — low-meat diets, heavy sweaters, hard-training athletes. If your zinc is fine, more zinc does nothing for drive: 5.2/10.

   A repair, not a booster.

   Why these numbers? ▾

   Effect size: In the fertility meta-analysis, CoQ10 improved sperm concentration, motility and morphology (Lafuente 2013); that is fertility, not libido or erections. 5.6/10 rewards a measured reproductive effect while admitting it is not the effect most readers are after.

   Evidence: Randomised trials pooled in a 2013 meta-analysis agree on semen parameters; the largest single trials now carry an expression of concern, which holds Evidence at 7.6/10 rather than higher.

   Reliability: Men with poor semen parameters respond; men with normal sperm and low drive have no mechanism to gain from. Ubiquinol matters after 40. 5.4/10.

   For fertility, not for drive.

   Why these numbers? ▾

   Effect size: In deficient, overweight men a year of 3,332 IU/day raised total T by about 25% (Pilz 2011), and treating deficiency improved erectile-function scores in middle-aged men (Canguven 2017). In healthy, replete men a 12-week RCT found nothing (Lerchbaum 2017). Net: 4.4/10.

   Evidence: Two positive trials in deficient men against a clean null in replete men — consistent, but the sexual-function data is thin. 7.4/10.

   Reliability: Deficit-dependent: works in the low-D majority of indoor, northern men, does nothing at a 25(OH)D of 40+ ng/mL. 5.0/10.

   Why these numbers? ▾

   Effect size: The testosterone claim rests on rats (Jiang 2016). The one human RCT tested a Cistanche + Ginkgo combination for chronic fatigue over 60 days — not libido, not hormones (Kan 2021). 4.0/10 = traditional use plus a fatigue signal, nothing sexual measured in people.

   Evidence: Animal steroidogenesis data and a single combination trial where you cannot tell which herb did the work: 4.0/10.

   Reliability: 'Cistanche' on a label spans unstandardised whole-herb powder to 50% echinacoside extracts, and the species matters (C. tubulosa). Response is unpredictable by design — 4.2/10.

   Desert ginseng: promising in rats, unproven in men.

   • Effect size45%Small
   • Evidence40%Preliminary
   • Reliability15%Narrow

   Why these numbers? ▾

   Effect size: Icariin blocks PDE5 in a dish (Ning 2006) — the same enzyme ED drugs target — but at potencies far below sildenafil, and no standalone human trial has shown a libido or erection effect from the herb itself. 3.6/10 is the score for a plausible mechanism with no measured human payoff.

   Evidence: In-vitro enzyme assays and rodent work; the only solid human RCT on Epimedium is about bone density, not sex. No human sexual-function RCT holds Evidence at 3.4/10.

   Reliability: Product icariin content ranges from undisclosed to 50%, so two bottles are two different substances. That spread — plus a mechanism that only matters if PDE5 is your bottleneck — gives 3.8/10.

   A PDE5 inhibitor in a test tube — not in a man.
