retaone sits 47% below market the tracked market median on matched peptide/size rows. The catalog in this index is smaller than Core Peptides Direct's. On COA coverage, retaone rates partial and Core Peptides Direct 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.
Pricing data cannot settle that question, and we do not test products or verify fulfillment. Here is the evidence we do hold for retaone. We found certificates for around some of the in-stock products we track. Those certificates were signed by 1 lab, the newest tested October 6, 2026. 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.
We found certificates for around some of the in-stock products we track. The freshest was tested October 6, 2026. 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.
retaone states that orders ship from Cypress, TX. This is what the vendor says about itself, not something we have verified.
We have not recorded a shipping cost for retaone. Orders over $400 are listed as shipping free. Stated delivery is 2–5 days. Checkout is the only place these figures are binding.
At the time we recorded it, retaone listed credit or debit card, Zelle, wire transfer and cryptocurrency. Peptide storefronts change processors often, so the options at checkout may differ from what we hold.
We have none on record for retaone. 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.
Across 35 graded products, retaone's median price per mg sits 47.2% below the median for the same peptide at the same vial size. We track 19 products from them in total. Price per mg is the comparison unit: a cheaper vial holding less is not a cheaper product.
Product documentation
Across the tracked peptide products we hold for retaone, COA coverage rates partial. The public index contains 17 documents. Reported test dates in this set run from May 7, 2026 through Oct 6, 2026. That rating covers the full tracked catalogue for retaone, including products that are currently out of stock, so it can differ from the in-stock rating above. Based on the certificates our crawler found; vendors may publish more than we index.

Certificate assessment
10 evaluated certificates
10 graded · 0 not graded · 10 in the A range.
The sample prioritizes up to ten popular peptides from this vendor. Grades assess the document and its reported tests, not the vendor’s whole catalog or the safety of a product.
Automated checks can make mistakes. Open “Why this result?” for the reason and any review notice, and check the linked COA’s lot against your product. How grading works

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.
