Searched first, found bits of this scattered across old threads, so figured I’d start a proper one.
The thing nobody tells you is that the certificate is about one batch. Not the product. One batch.
Tried to verify a COA myself by emailing the lab on it. Never heard back. Not sure if that means anything.
The Institute testing page has 4 published GHK-Cu reports if you want actual numbers rather than vibes.
Thanks in advance, this community is usually pretty good about this stuff.
No replies yet. Be the first to add one.
oh that makes way more sense, cheers
Genuinely asking, not being difficult: what is the actual source for that? Everyone repeats it and nobody links anything.
If you want to check this yourself, ask the vendor which laboratory issued the certificate, then email that laboratory with the report number. Most will confirm or deny. The ones that go quiet tell you something.
The people who get burned are almost never the ones who asked questions first.
Batch-to-batch variation is the thing people underestimate. A passing result certifies one lot, not a product line, and vendors know most buyers do not make that distinction.
This exact discussion happens every six months and lands in the same place. Not complaining, just noting it.
Correct, and the same applies to the quantity assay.
