This estimate is derived from comparative pharmacology and peptide absorption literature rather than from direct human studies: What This Means If you take 10 mg orally, approximately 3.8 mg reaches systemic circulation The remaining 6.2 mg is metabolized by stomach acid, proteases, and first-pass liver metabolism before reaching the bloodstream However, this systemic bioavailability may not directly reflect brain bioavailability (the amount reaching the central nervous system) Brain Penetration A critical distinction: systemic bioavailability (what enters the blood) differs from brain bioavailability (what crosses the blood-brain barrier and reaches neural tissue)
