Questions about Peptagon
Is Peptagon legit?
Pricing data cannot settle that question, and we do not test products or verify fulfillment. Here is the evidence we do hold for Peptagon. We found no certificates for the in-stock products we track. Based on the certificates our crawler found; vendors may publish more than we index. Read each certificate yourself, check that its lot and compound match what you are buying, and treat anything we have not recorded as unknown rather than as an answer.
Does Peptagon publish COAs?
We found no certificates for the in-stock products we track. Based on the certificates our crawler found; vendors may publish more than we index. We have not recorded a testing or COA page on their site. A certificate on file records what a document says; it cannot prove chain of custody or what is in the vial you receive.
How do Peptagon prices compare to other vendors?
Across 46 graded products, Peptagon's median price per mg sits 21.8% below the median for the same peptide at the same vial size. We track 38 products from them in total. Price per mg is the comparison unit: a cheaper vial holding less is not a cheaper product.

A record appears on file after our pipeline identifies the document as a certificate of analysis and matches its printed compound to a catalog peptide. The record cannot prove authenticity, chain of custody, sterility, product safety, or suitability for use.
These are counts of documents in our index, and a coverage rating of what our crawler found. They do not grade vendor quality, legitimacy, or safety. Printed fields can contain transcription errors. “Older record” means the reported test date is more than 18 months old.
