Why certification matters
You can’t see purity. Two vials with identical labels can contain very different things, and published lab analyses have found custom peptides containing undeclared ingredients. A Certificate of Analysis (COA) from an independent lab is how you check.
What a good COA tests
Is it the right molecule?
Confirms the molecular weight matches the peptide on the label, so you are not getting a different or incomplete sequence.
How much is the target peptide?
Shows what percentage of the sample is the intended peptide versus impurities, fragments or byproducts of synthesis.
Is the amount right?
Confirms each vial actually holds the stated amount, for example 10 mg, so labeling is accurate.
Is it clean?
Endotoxin (bacterial toxin) and sterility testing matter most for anything injected; not every COA includes them, so check.
Green flags
- Lot-specific: the lot number on the report matches your vial
- Issued by a named, independent third-party lab
- Lab is accredited (look for ISO/IEC 17025)
- Recent test date and a unique report ID
- You can verify the report with the lab (QR code or lookup)
Red flags
- One generic “99% pure” image reused for every product
- No lab name, no date, or no lot number
- Seller can’t tell you which lab tested it
- Report can’t be verified with the lab
- Only purity shown, with no identity test
