- Does Procapil block DHT without affecting hormones? What the evidence shows Procapil's supplier describes it as inhibiting 5-alpha reductase at the scalp without changing hormone levels, but the published support is cell and animal work plus one small human study of a caffeine-plus-Procapil formula. It is a cosmetic ingredient, not an approved hair-loss treatment, and no trial has compared it with finasteride or minoxidil.
- Can I use clascoterone if I'm undergoing gender-affirming hormone therapy? No published clinical trial has tested clascoterone in people on gender-affirming hormone therapy, so its safety in that group is unknown. The FDA label reports low systemic exposure and no described effect on blood testosterone, but it also records HPA-axis suppression and raised potassium in a small minority of subjects.
