we dont know even IF type I 5alphaR is even present in the follicle....no revivogen as far as i know is just a receptor blocker...in other words to binds at the receptor site so test and dht cannot.
Actually, the fatty acids in Revivogen are most well-known for their ability to inhibit 5a-reductase. There are at least half a dozen studies on that very issue, both in vitro and in vivo.
On the other hand, there are also at least a couple of other studies which suggest that those fatty acids also seem to have some ability to interfere with androgen receptors, although I don't think that effect is as potent as the other one.
