Red flags
If you take peptides and still don’t know what a “research record” is — good. That phrase is junk. This page is the actual list.
A screenshot instead of a PDF
Phone crop, Instagram story, Telegram JPEG. No letterhead you can click, no report number, no way to see if the footer was cut off. A real COA is a document from a lab. Here’s what that looks like.
No lot, or a lot that doesn’t match
The vial says one code. The PDF says another. Or the PDF has no lot at all. Then you cannot tell if the report is for the bottle in your hand.
“99%” with no milligrams
Purity is how clean the peak is. Net content is how much is in the vial. A 10 mg label that tests at 10.42 mg is normal. A 10 mg label with no milligram line is incomplete.
A blend sold as one number
KLOW is four peptides. A real report lists each one. The Peak KLOW COA on the COA page shows 69.59 mg found vs 80 on the label — that’s the useful part. A single 99.93% stamp is not.
No lab name
Anonymous “third-party tested” with the header cropped off. If you cannot name the lab, you cannot check the lab.
Human-use copy
Weight-loss claims, “stack this for fat loss,” dosing in the product description. Research vendors that talk like a clinic are either sloppy or lying about what they’re selling.
Telegram-only, no product page
You cannot match a lot to a listing if there is no listing. Chat screenshots are not documentation.
Price that only works if the bottle is empty
A low number is not a red flag by itself. A low number plus no COA is. Do the price per mg after shipping, not before.
What is not a red flag
- A lab using a different name than the storefront (GLP-3 vs retatrutide) if identity is confirmed.
- Slight overfill (10.42 mg on a 10 mg vial).
- A vendor being sponsored — as long as you still open the PDF. Peak is sponsored here. Code PEAK20. You still read the report.
