I’m looking into purchasing some to try and I’m all about finding the least expensive quality option. I’m specifically looking at Aloha GPC and noticed it’s much cheaper on Ali Express. I tried researching how to find a quality one, but they all seem to be the same. Any downsides to trying it from Ali Express?
Not sure about Ali Express or other, but if it helps: my company purchases a couple of tons of A-glyceryl Phosphoryl Choline each year, generally in 100k lots, and our best price directly from China is $140 per kilo, so use that as about absolute bottom. This is for 99% pure. AGP is extremely hygroscopic, so it usually comes in a 50% solution (with 50% magnesium stearate or some other anticaking), so be sure you check if it’s the 99 or the 50. If you’re only looking for a kilo at a time, I’d suggest getting it from a more local seller (Amazon, etc), depending on where you live.

I bought fish with a made in china label from walmart and it tasted really bad. China has some very very serious air pollution problems.
