About PeptidePub
PeptidePub is an independent price-comparison and research reference for the whole peptide market. We compare prices across labs, rank vendors on independent third-party testing, and publish plain-English guides — so you can figure out what to buy, from whom, and at what price. We don't sell peptides or provide medical care.
Who We Are
We're a small, independent team that got tired of watching people overpay for peptides — or get burned by vendors selling unverified product. The information you need to buy smart is scattered across forums, spreadsheets, and marketing pages. We built PeptidePub to put it in one place: real prices, real testing data, and honest guides.
What We Cover
The full research-peptide landscape — from GLP-1 and multi-agonist weight compounds like semaglutide (GLP-1), tirzepatide (GIP/GLP-1), and retatrutide (GIP/GLP-1/glucagon triple agonist) to recovery, longevity, growth-hormone, and cognitive peptides such as BPC-157, TB-500, GHK-Cu, and more. For each, we offer a plain-English guide, a per-milligram price comparison across vendors, and vendor trust rankings.
How We Rank Vendors
Vendor rankings are built on evidence you can verify yourself — independent third-party lab results and batch-specific certificates of analysis — not marketing claims. Vendors cannot buy a better grade. You can read the full method on our methodology page.
How we make money
PeptidePub is free to read. We earn a commission when you buy through some of the vendor links and discount codes on this site, and we sell the Peptide Handbook. Vendor relationships never change a vendor's grade, its position in a price table, or whether we cover it at all. Grades come from published third-party test results, and prices come from each vendor's own checkout. If a vendor stops working with us, its listing stays and its grade stays. That is the whole model.
