Revivogen as a DHT blocker

[itsmyhairs]

So my current regime is minox for growth/thickness/some retention and a keto shampoo (revita) twice a week as what I believe is a mild androgen blocker for the scalp.

But I really want to add another topical that deals directly with the DHT, so far the only one I've come across that it's some weird experimental thing with a name that consists mostly of random numbers is Revivogen.

Has anyone used it Revivogen?
Is it any good?
Did you get results from it?
Is it snake oil?
