How It Works
Tongkat ali (Eurycoma longifolia) appears to increase free testosterone by reducing SHBG binding and lowering cortisol, rather than directly stimulating testosterone production. The 200:1 extract concentrates eurycomanone and related quassinoids. Blood monitoring is essential — this is not a TRT substitute.
Free Testosterone
RCTs show ~15% increase in free testosterone in men with low-normal levels after 4 weeks.
Cortisol Reduction
Reduces cortisol by ~16%, improving the testosterone:cortisol ratio.

SupplementsCreatine Dose: 5g Daily for Muscle, Bone, and Brain
Take 5 g of creatine monohydrate every day for muscle, bone, and brain. You do not need a separate higher daily dose for bone — the bone research is still early and is studied with lifting, at ordinary doses. Some short brain studies use about 10–20 g a day, split up. That is a research protocol, not the daily dose this guide uses. Saturation from 5 g a day is the default.
