Vendor scores grounded in lab results
Every vendor is rated on certificate-of-analysis freshness, third-party lab testing, and how much of their catalog you can actually verify. You are reading 96 independent lab tests, not marketing copy.
Independent peptide research portal
Compare peptide vendors with the lab data to back it up.
Trusting a research peptide vendor usually means digging through forums, lab reports, and scattered studies. Peptide Portal puts scored vendors, third-party lab results, live pricing, and the research in one place.

The problem
Buying research peptides is really a trust problem.
Purity claims are hard to verify. Certificates of analysis go stale or never existed. Prices swing wildly between storefronts, and the actual science sits behind a dozen different journals.
Peptide Portal does that legwork once, in the open. Vendors are scored on lab testing and transparency, prices are tracked across the market, and every compound links to the research.
What you get
Backed by the research
232 indexed papers across 67 compounds, each guide noting mechanism, evidence, and regulatory status by region.
Real pricing, side by side
Price per milligram tracked across 989 price points, so you see the whole market instead of one storefront.
A look inside
Compare any peptide at a glance.

Research grade
Grounded in the research, not the hype.
We index the literature so you can check claims at the source. 105 of the 232 papers on file were published in 2020 or later, and 96 third-party lab tests keep vendor quality honest.
Questions
Good to know.
Is Peptide Portal medical advice?
No. Everything here is for research and educational purposes only. Peptides listed are not intended for human consumption, and nothing on the site is medical advice.
What does a vendor score actually mean?
Each vendor is rated on certificate-of-analysis freshness, third-party lab testing from labs like Janoshik and Finnrick, and how much of their catalog can be independently verified. The score reflects transparency, not a paid placement.
Is it free to use?
Yes. Create a free account to unlock the full marketplace, vendor comparisons, pricing, and the research library. There is no paywall.
Where does the data come from?
Vendor catalogs, independent testing labs, and published scientific literature. Pricing and lab results are refreshed continuously so comparisons stay current.
