What is Finasteride?
Finasteride 1mg is a low-dose formulation of the competitive 5α-reductase Type II inhibitor — the clinically established dose for androgenetic alopecia research models. At 1mg, scalp and serum DHT are reduced ~60–70%, with minimal impact on total testosterone. Enables hair follicle DHT research, dermal papilla AR sensitivity studies, and dose-comparative 5α-reductase inhibition protocols. Research use only.
Research Applications
Hair Follicle DHT Research
Scalp DHT reduction, dermal papilla AR sensitivity, follicle miniaturisation models
