About pepmg
pepmg is an independent price-transparency project for the research-peptide market. We exist to answer one question honestly: where is this compound cheapest per milligram, right now?
▸ What we do
- Track public vendor prices and normalize them to cost per milligram.
- Publish live comparison tables, price history, and an open data feed.
- Explain how to read a Certificate of Analysis (COA) so buyers can judge quality, not just price.
▸ What we are not
- We are not a vendor. We sell nothing and ship nothing.
- We give no medical, dosing, or human-use advice. All listings are laboratory/research reference data.
- We are not pay-to-rank. Placement is by $/mg only.
▸ Independence & disclosure
pepmg has no affiliate relationships yet, so today we earn nothing from any link — but our ranking will always be by $/mg, never by who pays. As we partner with vendors, any paid link gets disclosed right here and still can't change its rank. Vendors: see /partners to get involved.
When we do form an affiliate relationship, we disclose it inline on every affected listing — clearly, near the link, per FTC guidance. Disclosure never changes our ranking.
▸ Editorial
Price data is machine-collected and refreshed automatically; methodology is public at /methodology. Compound explainers are reviewed for accuracy and carry no usage guidance. Corrections: hello@pepmg.com.
