Skye Peptides sits 8% above market the tracked market median on matched peptide/size rows. The catalog in this index is smaller than Peptide Warehouse's. On COA coverage, Skye Peptides rates limited and Peptide Warehouse 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.
We have indexed 6 public posts naming Skye Peptides in the last 180 days (6 on Reddit across everything we hold), the most recent on Jun 15, 2026. These are links, not findings: we have not verified anything claimed in them.
Pricing data cannot settle that question, and we do not test products or verify fulfillment. Here is the evidence we do hold for Skye Peptides. We found certificates for a few of the in-stock products we track. Those certificates were signed by 2 labs, the newest tested June 15, 2026. Based on the certificates our crawler found; vendors may publish more than we index. Skye Peptides states its products are made in the USA; we have not verified that. 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 a few of the in-stock products we track. The freshest was tested June 15, 2026. Based on the certificates our crawler found; vendors may publish more than we index. Their own testing page is at https://skyepeptides.com/test-reports/. A certificate on file records what a document says; it cannot prove chain of custody or what is in the vial you receive.
Skye Peptides states that orders ship from Los Angeles, California, US. This is what the vendor says about itself, not something we have verified.
We have not recorded a shipping cost for Skye Peptides. Their shipping page is at https://skyepeptides.com/shipping-and-payments/. Checkout is the only place these figures are binding.
At the time we recorded it, Skye Peptides 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 Skye Peptides. 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, Skye Peptides's median price per mg sits 8.0% 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.

Certificate assessment
9 evaluated certificates
9 graded · 0 not graded · 0 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.
