Well, this one's not great. Specimen PI-LAB-2025-114 just went up for Cascade Research Group's GHK-Cu and it failed.
Purity came in at 69.1%. From what I understand they buy a second one from a different lot and send it to a different lab before they'll publish a failure, so this isn't a one-off reading.
Has anyone else bought from this lot? Trying to work out if it's just this batch or something broader.
