Figured I’d write this up while it’s fresh.
Tried to verify a COA myself by emailing the lab on it. Never heard back. Not sure if that means anything.
What I want to know is how much of the difference between vendors is real and how much is just measurement noise.
Worth noting there’s 4 published GHK-Cu reports published, which is more than I expected honestly.
Happy to be told I’m wrong, genuinely.
