What I meant by 100ml was to ease the equation, so if you want a 5% solution with 5g dht, you would need 100ml dmso, but if you want a 5% solution with 2.5g dht, you need 50ml dmso.
About the moisturizer, good point, but dmso itself is very liquidy so some gel like substance like pure aloe vera could make application easier. Totally not needed though.
So if you dissolved 5grams of dht into 100ml dmso, the concentration would be 5%, and if you applied 1ml of that solution, you would get 50mg dht.
PS: The prior post talks about milligrams instead of grams so mb.
