Dmso has a strong smell if used orally. Like rotten eggs or garlic. Use peg with dmso or use ethanolCayman chems had the solubility of dmso at 20mg/ml and xkawn is a very knowledgeable well know member here. Plus dmso is an organic super solvent, it holds almost every substance at a higher concentration than PG/PEG400/H2O.
I’m confident It’ll dissolve at 19mg/ml but I will report back.
