About Peptide Research Review

Peptide Research Review is an independent publication focused on quality verification in the research compound market. We publish annual supplier evaluations using blinded, third-party HPLC analytical testing. Our mission is to bring transparency to a market that has historically operated without it.

We are not a supplier, distributor, or manufacturer. We do not sell research compounds. Our testing costs are funded through a combination of affiliate relationships with some of the suppliers we review and reader support.

How we test

All orders are placed as standard retail purchases. No supplier is notified in advance. Samples are blinded before being sent to an independent analytical laboratory using reversed-phase HPLC with UV detection at 220nm. Each sample is run in triplicate and the results averaged. Full methodology is available in our methodology page.

How we make money

We are an affiliate publisher. Links to ROEHN Research, Prime Lab Peptides, and Peptide Sciences may generate affiliate commissions. These relationships help fund our testing program. Affiliate status has no influence on scoring methodology or rankings — all testing is performed by a third-party lab under blinded conditions where the lab does not know which samples are from affiliate suppliers.

No supplier pays for placement. No supplier sees the report in advance. No supplier selects which batch is tested.

Editorial policy

• No supplier is contacted prior to the testing window.
• Test samples are purchased anonymously and shipped to a standard retail address.
• The testing laboratory operates independently and is blinded to supplier identity.
• Rankings are determined solely by the six-criterion scoring rubric described in our methodology.
• We do not delete or modify findings after publication, even if a supplier disputes them. Corrections are appended as updates with timestamps.
