I took finasteride a long time ago for 1 week and I started experiencing hair loss, but this was without HRT. now i want to order dutasteride and take it cpa and hrt. I think there will be no hair loss.CPA do not block DHT. It has the same effect that e2 has, it lowers LH and FSH so T goes down and the DHT gets lower but not because CPA or e2 are blocking it directly but because T gets lower so the T that was gonna be converted to DHT does not occur. Dutasteride lowers more pathways than the T to DHT conversion that is way even on HRT ppl keep using dutas. Also bica is widely used when you are on HRT and keep getting androgen symptoms, because bica also lowers 3a diol G.
