The cornerstone of the formula. Multiple randomised trials in men aged 40–65 show Tongkat Ali at this dose lowers cortisol and SHBG, increases free testosterone, and improves muscle force output over a 4–12 week course. Sourced from Malaysian growers.
Job Raise free testosterone, lower stress hormones.

The libido and drive lever. Multiple double-blind trials in healthy aging men report meaningful improvements in sexual function, morning energy, and mood at this dose over 8–12 weeks. Effects on serum testosterone are inconsistent — but the felt outcomes are robust.
Job Support libido, drive, mood.

Required by the Leydig cells in the testes to actually synthesise testosterone. Roughly one in three men over 50 in U.S. intake studies falls short of the recommended daily amount. We use the bisglycinate form for tolerability and absorption.
Job Close a near-universal deficiency.
Studies Prasad 1996, Netter 1981.
More hormone than vitamin. Receptors for D3 sit on testosterone-producing cells. Northern-latitude wintertime deficiency runs above 60% in middle-aged men. Restoring D3 to clinically adequate levels has, in deficient populations, produced measurable testosterone increases.
Job Close a second near-universal deficiency.

Compounds commonly observed in commercial men's-vitality units that were assessed and excluded from the protocol. Rationale per compound below.
Largely failed in well-controlled human trials. Persistent in marketing, absent in our formula.
Initial trials showed promise; follow-up trials in trained men showed no effect or, in some, a decrease.
A perfectly fine adaptogen — but it doesn't move testosterone. We don't put filler on the label.
