Pycnogenol (standardized extract)
Prescription-only and clinician-directed — this is a controlled substance, NOT a self-administered supplement, and we do not provide a non-medical dosing protocol. For context only: TRT for diagnosed hypogonadism is titrated to a mid-normal testosterone level. Intramuscular testosterone esters (cypionate/enanthate) are commonly dosed around 50–100 mg weekly (or ~100–200 mg every 2 weeks); long-acting testosterone undecanoate is dosed less frequently. Transdermal gels (~50–100 mg/day applied) and subcutaneous injection are alternative routes. Supraphysiologic anabolic-steroid doses are far higher and dangerous — not a regimen this library endorses.
