Which peptide cases went past a warning letter?

By Paul Harris, Standards EditorRecorded September 2026 · Standard v1.1 · How checks are performed

5 federal cases since 2020 against people selling peptides or research-labeled GLP-1 drugs ended in a guilty plea or a prison sentence, and 1 more is charged and undecided. None of them names a seller in this ledger. 28 FDA warning letters name 28 ledger records, and every one of those sellers still has its record open.

A letter and a case are different things

FDA describes a warning letter this way: A Warning Letter is informal and advisory. It communicates the agency's position on a matter, but it does not commit FDA to taking enforcement action. A court action is the step after it. FDA's manual defines an injunction: An injunction is a civil judicial process initiated to stop or prevent violation of the law, such as to halt the flow of violative products in interstate commerce, and to correct the conditions that caused the violation to occur. A criminal case goes further, to a plea or a verdict. The Standard fails S8 only on an action that halted a business, and records a letter without failing anyone.

The cases, as the Department of Justice reports them

Charged, with no plea or verdict reported:

The label on the product ran through almost every case. Research use, laboratory use and not for human consumption are the phrases prosecutors quoted back, because the sellers knew customers were using the products themselves. Two older cases show the pattern is not new: Adam F. Higdon (October 15, 2013) and Ronald J. DeFranco (May 12, 2014).

A pharmacy in the ledger's records

6 ledger records name Tailor Made Compounding of Nicholasville, Kentucky, as a pharmacy that fills its orders: BiltRx, HealthHub, LaSara Medical Group, Marek Health, Nu Image Medical, Try Invigor. The company that pleaded guilty was Tailor Made Compounding LLC. The pharmacy's own about page says The transfer of ownership in March of 2021 marked the beginning of a new era for TMC. The ledger records what each seller prints and does not treat a pharmacy's history as a finding about the sellers that use it; the pharmacy is not a seller under the Standard, and none of these records changes disposition because of it.

What was looked for and not found

No injunction, consent decree or seizure against a peptide or GLP-1 seller appears on FDA's compounding actions page, which lists decrees over sterile practice and insanitary conditions. FDA said in February 2026 that it may go further: Entities engaged in the manufacture, distribution, or marketing of unapproved compounded GLP-1 products should be aware that failure to adequately address any violations may result in legal action without further notice, including, without limitation, seizure and injunction. That is a statement of intent, not an action. Press reports of a 2025 warehouse raid and accounts of why Peptide Sciences closed have no primary document behind them that this site could open, so neither is repeated here.

How S8 records this

A seller named in a case like these, with its business halted by the outcome, would fail S8. No ledger record does today. The 28 letters are printed in full on the warning-letter pages, and each record carries its own. See S8, enforcement status.

Releases were read on justice.gov and fda.gov in September 2026. Counts are computed at build time against Standard v1.1.

Counts are generated from the ledger at build time, so this page cannot drift from the records it summarizes. Method and null semantics: how checks are performed. This page ranks nothing, recommends nothing, and carries no partner link.

Who sells retatrutide, a drug still in phase 3 trials?Research vendors sell it, labeled for laboratory use, several of them under a code rather than its name, while the maker has not filed it for approval and FDA states that it cannot be used in compounding.

Who stopped trading after Peptide Sciences closed?Few closed outright. More moved their catalogs behind an account or a password, and most still sell to a visitor, many behind an attestation screen.

Warning letters across the field, and what happened nextA warning letter alleges and does not halt. The lettered entities in this ledger are counted with their denominator, together with how many still trade and how many letters carry a close-out letter on the FDA index.

Which laboratories sign the research vendors' test reports?A handful of laboratories sign most of the reports, few of them state an accreditation on their own sites, and some vendors credit a laboratory on the homepage that signs none of their documents.
