American Peptide Research sits 53% above market the tracked market median on matched peptide/size rows. The catalog in this index is smaller than Tetrava Labs's. On COA coverage, American Peptide Research rates partial and Tetrava Labs rates none found. Based on the certificates our crawler found; vendors may publish more than we index.
The honest comparison unit is price per mg on matched peptide/size rows. COA coverage is presence of a current indexed document, not purity-as-quality. See the Evidence Atlas and how to read a COA.
Evidence boundary: Listed prices, stock signals, and indexed COA documents are observations. They do not establish legitimacy, authenticity, safety, sterility, chain of custody, product quality, fulfillment, or suitability. No vendor is endorsed.

Questions about American Peptide Research
Is American Peptide Research legit?
Pricing data cannot settle that question, and we do not test products or verify fulfillment. Here is the evidence we do hold for American Peptide Research. We found certificates for around some of the in-stock products we track. Those certificates were signed by 1 lab, the newest tested June 25, 2025. Based on the certificates our crawler found; vendors may publish more than we index. We have been recording their prices since July 3, 2026. 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 American Peptide Research publish COAs?
We found certificates for around some of the in-stock products we track. The freshest was tested June 25, 2025. Based on the certificates our crawler found; vendors may publish more than we index. Their own testing page is at https://www.americanpeptideresearch.net/coa. A certificate on file records what a document says; it cannot prove chain of custody or what is in the vial you receive.
Where does American Peptide Research ship from?
American Peptide Research states that orders ship from Englewood, New Jersey, US. This is what the vendor says about itself, not something we have verified.
How much is shipping at American Peptide Research?
We have not recorded a shipping cost for American Peptide Research. Orders over $200 are listed as shipping free. Checkout is the only place these figures are binding.
What payment methods does American Peptide Research accept?
At the time we recorded it, American Peptide Research listed credit or debit card. Peptide storefronts change processors often, so the options at checkout may differ from what we hold.
Does American Peptide Research have a coupon or discount code?
We have none on record for American Peptide Research. When a code we can verify appears, it shows on this page and the prices here are adjusted for it; until then, every figure on this page is the list price.
How do American Peptide Research prices compare to other vendors?
Across 44 graded products, American Peptide Research's median price per mg sits 52.5% above the median for the same peptide at the same vial size. We track 42 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.
