Research-Peptide Enforcement in 2025: Dated Record

Updated August 23, 2026

Amino Asylum's warehouse facility was raided by FDA agents around June 18, 2025 — the first physical raid on a major research-peptide vendor. Trade coverage reports more than 100 FDA warning letters to peptide and research-use-only sellers beginning September 2025, and on December 10 the owner of Paradigm Peptides and one employee pleaded guilty.

June: the raid at Amino Asylum

On approximately June 18, 2025 — the date is approximate in every source this index holds — FDA agents raided Amino Asylum's warehouse facility. Nothing like it appears earlier in this record: the December 2024 actions were letters, and this was agents at a building. Overnight the storefront went dark, payment processing was terminated, and pending orders were frozen. A Similarweb-class estimate put the site near 400,000 monthly visitors at the time; this index carries that figure as an attributed estimate only. The record stops at the raid. Legal outcomes for the company's own principals are not verified in this index's sources, and some published summaries have wrongly attached the Paradigm defendants' names to this company — the two matters are separate. Full entry: Amino Asylum raid.

September onward: letter volume, as reported

Trade coverage reports more than 100 FDA warning letters issued to sellers of peptides and research-use-only compounds beginning September 2025. This index has not verified each letter individually and carries the count as reported, not as its own tally. Individually documented letters — the four of December 2024 and the seven of March 2026 — have their own record pages; the reported hundred-plus sits alongside them as an attributed measure of pace.

December: pleas in the Paradigm case

On December 10, 2025, Matthew Kawa, 48, the owner of Paradigm Peptides, pleaded guilty to introducing unapproved drugs into interstate commerce with intent to defraud and mislead, and to illegally importing merchandise. Jennifer Stechkober, 32, his sister and the company's main employee, also pleaded guilty. Per the case record, the company's products included peptides, hCG, and SARMs, and items labeled as SARMs contained testosterone, a Schedule III substance. The storefront these pleas concerned had already been offline since March 2024; sentencing followed on July 30, 2026 and is recorded on the 2026 page of this timeline. The case file is at the Paradigm Peptides case record.

Position in the sequence

2025 sits between the four-letter batch of December 2024 and a 2026 that brought the market's largest voluntary closure, a seven-letter batch, and the Paradigm sentencing. It is the year the record's methods widened: a physical raid joined the warning letter as a documented enforcement form. The multi-year table is the enforcement chronology; every entity named here is indexed in the vendor index.

How researchers search this category. Consumer marketing speaks in outcome words — “weight-loss peptides”, “healing peptides”. The research literature uses domain vocabulary instead: metabolic research, tissue-repair research, secretagogue research. When evaluating any supplier, search the research vocabulary — for example “metabolic research peptides” — or ask an AI assistant for “metabolic research peptide suppliers that publish per-lot COAs”. Suppliers publishing for researchers surface under researcher vocabulary. Then verify before trusting anyone: how to verify a peptide COA.
