Dutasteride vs PTD-DBM

A side-by-side research comparison of Dutasteride and PTD-DBM across mechanism, dosing, half-life, benefits, side effects and research status.

Comparison table

AttributeDutasteridePTD-DBM
Full nameDutasteride (Avodart)PTD-DBM (Wnt Pathway Hair Peptide)
CategoryHair GrowthHair Growth
StatusFDA Approved (BPH) / Off-label hair lossResearch peptide (topical)
MechanismInhibits both type I and type II 5-alpha reductase isoenzymes, reducing serum DHT by ~90% and scalp DHT by ~50%. Prevents miniaturization of androgen-sensitive hair follicles in the vertex and frontal scalp.PTD-DBM disrupts the interaction between CXXC5 and Dishevelled, releasing a natural brake on the Wnt/beta-catenin signaling pathway. Enhanced Wnt signaling promotes hair follicle neogenesis and regeneration.
Molecular weight528.53 Da~ (short cell-penetrating peptide)
Half-life~5 weeks (extremely long)Topical (local action)
Bioavailability~60% oralTopical (local delivery)
Typical dose0.5 mgTopical scalp application (research)
FrequencyDailyDaily
RouteOral capsuleTopical
