It's the easiest way I could figure to get small samples of it for someone to try out. See, I don't know how sensitive one of my clients is to this stuff so I was going to make a concentration of something around 3mg yohimbine/20mg ephedrine per milliliter then just give her a 1/2 dose in a small vial to try out. Also, it's easier (and probably more accurate) than mixing it into capsules which was my original plan.
