So here's what I'm planning on, a topical Yohimburn-type product with a fair amount of caffeine in order to act as a localized diuretic. Since the sticky thread burned out a while back, I wanted to get an idea of what people think. Here it is...

500ml (~16oz)

55% Aloe Gel
13% d-limonene
10% Prop Glycol
5% BA
25g caffeine
12g Yohimbine HCL

This would make a solution that's 25mg/ml yhcl and 50mg/ml caffeine...think the above recipe will hold 75mg/ml? Any suggestions?
