Gerald I think you're on right track. H2O2 does a good job of dissolving aspirin. I just got a 1 LB. jar of pure aspirin powder from amazon for $12.65 shipping included. Only glitch for me is in Nevada, we only have 150 or so proof Everclear while most other states allow 190 proof. My next batch I'll try the aspirin powder, w/ 35% H2O2, and my lower proof Everclear, and I'll report here how it goes. I like not having fillers/ w/ aspirin.
