Cascade Research Group GHK-Cu failed verification (PI-LAB-2025-114), discussion

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.

Fair warning, the answer you get here will be better than the answer you get in the bigger subs, but it will still be people on the internet.

If your solution went cloudy after reconstitution that is usually either the diluent or the temperature it was stored at. Worth posting what you used.

Try the search on the testing database rather than the main search. Different index, catches specimen IDs.
