Lower risk of insulin resistance while still achieving threshold IGF-1 levels for follicular stimulation || Standard Hair-Focused Protocol | 25mg | Evening, 2–3 hours post-meal, 60–90 min before sleep | +80–95% above baseline | 6–12 months | Moderate hunger, mild lethargy, possible fasting glucose increase of 5–10 mg/dL | Most commonly used dose in anecdotal hair regrowth protocols. Produces robust IGF-1 elevation without requiring the higher doses used in muscle-wasting studies || Aggressive High-Dose Protocol | 50mg | Evening, fasted state, with glucose m
