The Paradigm Peptides Sentencing: July 30, 2026

Updated August 21, 2026

Paradigm Peptides owner Matthew Kawa was sentenced on July 30, 2026, to 70 months in prison, one year of supervised release, and a $5 million forfeiture; Jennifer Stechkober received 16 months. Both pleaded guilty on December 10, 2025. Sentencing took place at the federal courthouse in South Bend, in Indiana's northern district.

The offenses behind the sentences

Kawa's guilty plea covered introducing unapproved drugs into interstate commerce with intent to defraud and mislead, and illegally importing merchandise — the two offenses named in the public record, reproduced here without paraphrase. Stechkober entered her own plea the same day; the material this index has captured does not itemize her counts, so this page does not guess at them. Every legal characterization on this page belongs to the court record and to the announcement from federal prosecutors, not to this index.

What each element of the sentence documents

Custody. The prison terms — 70 months for Kawa, 16 for Stechkober — are the part of the judgment secondary coverage repeats, and often the only part. A custody figure is checkable in a way a rumor never is: a named court imposed it on a named person on a named date.

Supervised release. Kawa's sentence includes one year of supervised release, a period of court-ordered supervision that begins when custody ends. Its presence means the judgment reaches past the prison term.

Forfeiture. The $5 million forfeiture is the monetary component of Kawa's sentence — value surrendered to the government under the judgment. It is the element that puts a dollar figure on the offense conduct. How the sum was calculated, and what it consists of, is not captured in this record.

From plea to sentence

The pleas came December 10, 2025. The sentences followed on July 30, 2026. The storefront itself had been offline since March 2024 — the business was already gone before either defendant appeared in a courtroom. That ordering matters when reading secondary coverage, which tends to compress shutdown, plea, and sentence into one event. The dated sequence, alongside the warning-letter batches of December 2024 and March 2026, is kept on the enforcement timeline.

Where this record sits

These sentences closed the one research-peptide vendor case to end in prison terms. The full case history — chronology, the products at issue, the lookalike domain — is at the Paradigm Peptides case record, and the company's entry alongside every other documented closure is 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.
