What this protocol does

Natural approaches to optimizing testosterone through targeted supplements, resistance training, and lifestyle interventions.

What to expect

Synthesized from research on this protocol's components. Individual response varies.

Weeks 4–8

Look for: Strength gains from creatine paired with compound lifts begin to register — creatine plus resistance training increases chest press one-rep max and fat-free mass more than training alone after more than six weeks.

Not yet expected: Reliable testosterone elevation from vitamin D in this window — research suggests vitamin D treatment might increase testosterone in men, but the evidence is preliminary and effects vary by baseline status.

Backed by 2 studies

Creatine supplementation during resistance training in older adults-a meta-analysis.
Vitamin D and fertility: a systematic review.

Weeks 8–12

Look for: Continued lean-mass and strength accumulation from creatine plus training. With consistent dosing, vitamin D status (25-hydroxyvitamin D) reaches a stable elevated range that supports bone health and may modestly support testosterone in deficient men.

Mortality or cardiovascular benefits from vitamin D — those endpoints emerge in long-term studies (3-6 years), not within 12 weeks.

Low vitamin D correlates with low testosterone — foundational

Cutaneous vitamin D synthesis is minimal above 35° latitude from October through April (northern hemisphere) or May through October (southern hemisphere). Outside this window, prioritize 15-30 min of midday sun exposure; supplementation is optional.

Reduces SHBG — increases free testosterone bioavailability

Boron at this dose is included to nudge free testosterone in men. Women have different SHBG/E2 dynamics; if you want the bone-density benefits of boron, that's a separate (lower-dose) conversation.
