Core Peptides is a US research-peptide vendor that lists 65 injectable peptides and 2 blends, including Epitalon, PT-141 and KPV. Across 65 products with a market median, its prices sit 7% above the median for the same peptide and vial size; it is the cheapest vendor we track on GHRP-2 and GHRP-6, and pricier on MOTS-c and TB-500. We found certificates for most of the in-stock products we track. Based on the certificates our crawler found; vendors may publish more than we index. Shipping is free over $200; it accepts card.

Median price per mg across Core Peptides’s 65-67 priced listings, from Aug 3 ($6.75/mg) to Oct 12 ($6.53/mg) over 11 observed days. The mix of products behind the median changes as listings come and go, so this tracks the catalog as well as the prices.
1 of Core Peptides’s tracked listings changed price in the last 30 days: 0 down, 1 up.
Listed prices at Core Peptides against the median price per mg for the same peptide at the same vial size, across every vendor we track. Vendors change prices without notice, so check the current listing before you order.

Core Peptides sits 7% above market the tracked market median on matched peptide/size rows. The catalog in this index is larger than Disguised Alpha's. On COA coverage, Core Peptides rates broad and Disguised Alpha rates broad. 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 cannot answer that from pricing data alone, and we do not test products. What we track is their listed prices, how those compare to the market, their stock signals, and the certificates of analysis we hold — we do not verify product quality, purity, or fulfillment. For quality assurance, check each product's certificate and any independent third-party testing.
We found certificates for most of the in-stock products we track. The freshest was tested July 22, 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.
Core Peptides states that orders ship from US. 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 Core Peptides. Orders over $200 are listed as shipping free. Their shipping page is at https://www.corepeptides.com/shipping/. Checkout is the only place these figures are binding.
At the time we recorded it, Core 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 Core 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 65 graded products, Core Peptides's median price per mg sits 6.5% above the median for the same peptide at the same vial size. We track 61 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 Core Peptides, COA coverage rates broad. The public index contains 157 documents. Reported test dates in this set run from May 11, 2024 through Jul 22, 2026. That rating covers the full tracked catalogue for Core Peptides, 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
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.
