You have to sign up for a Reddit account. Super simple. Once you do that you will find the r/sfn section if you type in that wording on the search icon. Someone just posted the link on Google that has the ingredients on the topical gel that you mix with pirenzepine. It has the milligrams and you would need a milligram scale which Amazon has. DMSO, propylene glycol, polyethylene glycol, polyoxyethylene glycol, citric acid, sodium hydroxide, methylcellulose, glycerine, NAOH, ethanol, benzyl alcohol, water, sodium citrate are the ingredients for the topical. This is for the straight up pirenzepine dihydrochloride raw powder not the freebase monohydrate pirenzepine. All freebase does is increase the drying time. It doesn’t affect the efficacy. It was used in the clinical trials for that reason.
