Beware using non-pharmaceutical grade ingredients. Lab grade is not the same as pharmaceutical grade. If things go wrong then the liability is on you. It may also have implications for your health insurance.
I have commented on this before, caveat emptor:

- refurb 6y agoAs a former chemist this. Pharmaceuticals are developed for human consumptions with defined limits for things like heavy metals, residual solvents, etc. Bulk manufactured chemicals are not. You’ll often by see them sold at 98% purity and the remaining 2% can be whatever. Even if they are 99.9% pure, the remaining 0.1% can be metals used in the manufacturing process, carcinogens or toxic solvents. Kind of like the different between ethanol, USP (pharmaceutical grade ethanol) versus ethanol, 99%. If no one is drinking the ethanol they don’t care if it contains traces of benzene, methanol, etc. Beware.
