PeptidePrices Publishes a Directory of 336 Rated Research-Peptide Vendors and 267 Verified Coupon Codes

Every vendor review is written by the PeptidePrices editorial team and scored on one published rubric, and every coupon code is re-verified weekly.

BOSTON, Nov. 10, 2026 /PRNewswire/ -- PeptidePrices (peptideprices.net), the all-in-one source for the peptide industry, today published a vendor directory of 336 research-peptide vendors at https://peptideprices.net/vendors, each rated from 0 to 10 on one published rubric, and a coupon hub of 267 verified vendor coupon offers at https://peptideprices.net/coupons. The directory has grown rapidly, from 30 vendors in June to 103 in September and 336 today.

Why PeptidePrices built the vendor directory. Checking a peptide vendor's certificate of analysis (COA) used to mean hunting through vendor sites and laboratory portals, with no single place to confirm that a report is genuine, current and tied to the product on sale. A screenshot or PDF can be cropped, reused by another seller or altered, and nothing on its face reveals that. A low price can also arrive with fake or missing certificates, customer complaints, poor service, undelivered orders or weak research-use-only compliance, so price alone says very little. The PeptidePrices price index at https://peptideprices.net/peptides shows each price next to its evidence. Every one of the 336 vendor reviews and profiles is handwritten by the PeptidePrices editorial team, led by co-founder Jack Ryan, and covers the vendor's laboratory evidence, customer-review history, business background, shipping policies and payment options.

What the directory includes. Every vendor carries a 0-10 quality rating; 74 score 9 or higher and 10 score a perfect 10. The COA library at https://peptideprices.net/coa-library holds more than 21,000 checked COAs, and each vendor profile gathers that vendor's certificates, so researchers can open the reports, inspect measured results and check the issuing laboratory's records without leaving PeptidePrices. The coupon hub lists 267 verified offers: 263 codes entered at checkout and 4 discounts applied through the vendor link, from 5% to 50% off. 211 carry exclusive terms for PeptidePrices readers.

How vendors are rated. COA practices carry 40% of each score: a named third-party laboratory, batch linkage, public reports, testing breadth and independent verifiability. Community reputation, transparency and operations carry 20% each. The full methodology is at https://peptideprices.net/trust.

How coupons are verified. Every coupon code is re-verified by the PeptidePrices editorial team every week. Each vendor's coupon page states the code and the discount, and the full list is published as a downloadable coupons.json file.

"Researchers kept asking us two things: which vendors can I trust, and is there a working code. We now answer both on one site, with a published score for every vendor we list and a check date on every code," said Jack Ryan, co-founder of PeptidePrices.
