- | Factor | Finasteride (Propecia) | Copper Peptides (GHK-Cu) | TB-500 / BPC-157 | Professional Assessment ||—|—|—|—|| Mechanism of Action | 5-alpha reductase inhibition. Reduces DHT systemically by 60–70% | Collagen synthesis upregulation, MMP downregulation, copper-ion-mediated tissue repair | Anti-inflammatory cytokine modulation, angiogenesis promotion at follicle bulb | Finasteride directly addresses the androgenic driver of miniaturization; peptides support tissue health without hormone suppression || Clinical Efficacy (Regrowth) | 65% experience visible regrowth at 12 months (Phase III data) | 40–50% experience measurable density increase at 6–9 months (limited trial data) | Insufficient published data. Mostly anecdotal or case reports | Finasteride has stronger evidence base; peptides require longer observation periods || Administration Route | Oral. 1mg daily | Topical. Twice daily application to scalp | Subcutaneous injection or topical (absorption variable) | Oral finasteride
