Research Peptide Vendor Shutdown Tracker (2025–2026)

By the Banger Labs Research Team · Last updated June 2026

Short answer: Three major research-peptide vendors closed in 2025–2026 — Peptide Sciences (Mar 2026), Amino Asylum (FDA-raided, 2025), and Science.bio (Jan 2026) — amid an FDA enforcement wave (50+ warning letters, 2024–2025). The tracker below is dated and updated as the market changes.

2025–2026 shutdown tracker

Vendor	Status	Date	What happened
Peptide Sciences	Closed	Mar 6, 2026	Voluntarily ceased operations without warning; catalog pulled offline, pending orders left unfilled (reportedly ~$7.4M/month in sales).
Amino Asylum	Closed — FDA raid	Jun 2025	FDA raided its Memphis, TN warehouse; site went offline within days. Founders later pled guilty to federal charges (Dec 2025).
Science.bio	Closed	Jan 27, 2026	Ceased operations — one of at least eight significant vendors to exit in roughly nine months.

Why vendors are closing

The 2026 contraction reflects intensifying enforcement: the FDA issued 50+ warning letters to peptide sellers across 2024–2025, and several large operations exited the market — some voluntarily, some after federal action. For buyers, the lesson is to prioritize vendors with verifiable testing transparency and compliant, research-use-only operations.

How to choose a replacement

Insist on independent, batch-specific COAs (≥99% HPLC), US-based fulfillment, card payment, and strict research-use-only labeling — see the best-vendors buyer’s guide and our COA Library.
