Not enough matched products to compute a price position for Simple Peptide. The catalog in this index is smaller than Fusion Peptide's. On COA coverage, Simple Peptide rates not assessed and Fusion Peptide rates partial. 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 Simple Peptide. We track 51 listings from this vendor and have not assessed certificate coverage for them yet. We have been recording their prices since March 6, 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.
Their own testing page is at https://simplepeptide.com/certificate-of-analysis/. A certificate on file records what a document says; it cannot prove chain of custody or what is in the vial you receive.
Simple Peptide states that orders ship from Delray Beach, FL. They state that they do not ship internationally. This is what the vendor says about itself, not something we have verified.
We have not recorded a shipping cost for Simple Peptide. Their shipping page is at https://simplepeptide.com/shipping-returns/. Checkout is the only place these figures are binding.
At the time we recorded it, Simple Peptide listed credit or debit card. Peptide storefronts change processors often, so the options at checkout may differ from what we hold.
We have none on record for Simple Peptide. 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.
Product documentation
Across the tracked peptide products we hold for Simple Peptide, COA coverage rates limited. The public index contains 4 documents. Reported test dates in this set run from Aug 6, 2026 through Aug 6, 2026. That rating covers the full tracked catalogue for Simple Peptide, 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
4 evaluated certificates
4 graded · 0 not graded · 4 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.
