Topical Dutasteride Experiences

After years of blasting/cruising I started noticing some hair loss. I already use minoxidil, ketozolin shampoo and have been microneedling.

Did my research (also at this forum) what to do about it / how to slow the process down. The result is I want to add topical dutasteride to my anti-hair loss stack, but can’t find a reliably looking online source to buy from.

Interested to hear about your experiences of using topical dutasteride while blasting/cruising. Also would love to hear if anyone has a reliable online sources (if possible in Europe).
