Retrograde menstruation is when menstrual blood flows back through the fallopian tubes and into the pelvic cavity instead of outside
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)
Many people notice better energy or mental clarity within a few days, while others see a steadier change over 12 weeks
