Raw purity

[oginfamous]

Hello everyone, new here. Already did an introduction but this is my first real post. Getting into home brewing and I'm most likely going to have my raws test if the price isn't too heavy(if anyone know a good lab that does testing please msg me) but my question... what is the purity of most of these raws that are coming out of china. I swear they all claim 98%-99% but how many truly are in the 90s upper 90s. I guess what I'm wondering is, Is does everyone assume they are under 98-99% and add extra powder to their brew to make the dose more accurate? Might be a dumb question. But hey I'm new to this

Purity is around 70%-80%
Most are about 20% underdosed. At least that what most people are saying.
As for testing, that shit is expensive when you talk real mass spec testing. And I think simec does maybe raw powders but not sure.
When you mean just testing if some aktive substance then buy a labmax. Not to expensive and reliable. It's not really worth testing purity with mass spec if you just buy for yourself and a couple of frieds.

Does anyone know of a testing or could refer me to someone who does purity testing?

Purity is dependent on batch. You could get a 98-99% testing one time, but get lower on the next batch. Since its homebrew and for personal use save your money and put it towards bloods maybe?

If you mass spec each supplier or even batch it's gonna cost you a fortune.

Yes definitely for personal use just do bloodwork. But if your ordering by the kilo mass spec is worth it

Raws are improving, but 99% nope. 70-80% may be a bit pessimistic. I think you will do better than that.You can test raw if you have a hook up, but for a new guy, good luck.
