Updated monthly. Every cell verifiable from public sources. Last updated: September 2026.
The peptide market changed dramatically in 2025–2026 — Peptide Sciences shut down (Mar 2026), Amino Asylum was raided (Jun 2025), and 7 other major US vendors closed in 12 months. Below is the current state of the field.

Methodology
Every data point above is verifiable from public sources: vendor websites, Janoshik verification URLs, Trustpilot pages, Reddit r/Peptides threads, and the vendors' own COA pages. Where a data point isn't publicly verifiable, we mark it "—" rather than guess.
What we don't claim: We don't manufacture peptides. We don't pretend to be the oldest vendor. We don't fake review counts. We don't claim every catalog SKU already has a live certificate.
What we do claim: Independent Janoshik re-tests on published shipping lots in our public COA library (lot-traceable certificates on hand — not a claim that every catalog SKU is already covered), and a real Telegram bot ordering experience.
