This is how I attempted to dissolve the powder:
7-Keto-DHEA
300mg powder
1/2 oz. dropper bottle
~15% isopropyl myristate (I don't think this is necessary, but I had some left over from dissolving DHEA powder)
~80% ethanol
(~5% powder)
~300 drops
~1mg per drop
It didn't fully dissolve, but that's because there are excipients in the capsule like silicon dioxide and magnesium stearate. I don't think that there exists a commercially available source of pure 7-Keto-DHEA powder.
When I apply 10mg to my navel I get sleepy as heck, but that could also be because I'm laying down when I do it lol
