What is the research-peptide price index?

The research-peptide index

Every peptide, every vendor — one honest price.

Q: Why does Peptide Watchdogs show vial prices?

Vial price is what you actually pay at checkout, and it is unambiguous — a listed vial size and its price, with no derived math that can be off. We show the vial size next to every price so different sizes are easy to compare. For research use only.

Q: What does the Verified badge mean?

Verified means a vendor's batch-tied COAs (HPLC purity plus mass-spec identity), review authenticity, and pricing data held up under independent checking. It is not a health or safety endorsement, and it cannot be bought.

Real vial prices, third-party lab verification, and screened reviews. Rankings never for sale — set by a published method, not by who pays. We never ask you for passwords or payment details.

Frequently asked

What is the research-peptide index?

An independent comparison of research-peptide vial prices across vendors, alongside third-party lab verification and screened reviews. Figures are current public market ranges until verified vendor listings load. For research use only.

How are vendors ranked?

By trust: verified third-party lab testing and screened reviews — never by who pays. Rankings and the Verified badge are never for sale; sponsored placements are clearly labeled and separate from ratings.

Why vial prices instead of a per-mg figure?

Vial price is what you actually pay, and it's unambiguous — a real listed size and its price, with no derived math that can be off. We show the vial size next to every price so different sizes stay easy to compare.

What does the Verified badge mean?

A vendor's batch-tied COAs (HPLC purity + mass-spec identity), review authenticity, and pricing data held up under independent checking. It's not a health or safety endorsement, and it can't be bought — see the standard.
