explain to me what serum dht means
topical finasteride will go systemic easily because of the low molucular weight, you may aswell take it orally.
DHT signals mainly in an intracrine and paracrine manner in the tissues in which it is produced, playing only a minor role, if any, as a circulating endocrine hormone.[3][4][5] Circulating levels of DHT are 1/10th and 1/20th those of testosterone in terms of total and free concentrations, respectively,[6] whereas local DHT levels may be up to 10 times those of testosterone in tissues with high 5α-reductase expression such as the prostate gland.[7]
Quoted from wikipedia
I read an article from Harvard some years ago, where they theorised, if i remember correctly, that serum dht is a small amount of the dht that doesnt manage to bind locally and joins the bloodstream, but doesnt seem to play a role. Could be wrong though
