TL;DR

On August 24, 2026, the FDA Center for Drug Evaluation and Research (CDER) issued Warning Letter 735067 to TXP Innovations LLC dba Tex Peptides (CEO Felicia Romero, Dallas, TX) for offering unapproved new drugs via website texpeptide.com, including Semaglutide, Tirzepatide, Retatrutide, SS-31, Tesamorelin, PT-141, and Bacteriostatic Water with Benzyl Alcohol, in violation of sections 301(d) and 505(a) of the FD&C Act. The FDA documented that website labeling made disease-treatment and metabolic-function claims for these products, establishing drug intent under section 201(g)(1) of the FD&C Act, and flagged injectable products as posing particular public health risk due to direct body delivery bypassing natural defenses.

# FDA Warning Letter Analysis: TXP Innovations LLC dba Tex Peptides

**The Company and Violations**

TXP Innovations LLC, operating as Tex Peptides and based in Dallas, Texas, received a warning letter from the FDA's Center for Drug Evaluation and Research (CDER) on August 24, 2026. The agency reviewed the company's website (texpeptide.com) in July 2026 and identified seven products marketed as unapproved new drugs: Semaglutide (GLP-1 SEM), Tirzepatide (GLP-2 TRZ), Retatrutide (GLP-3 RT), SS-31 (Elamipretide), Tesamorelin, PT-141 (Bremelanotide), and Bacteriostatic Water with benzyl alcohol. The FDA emphasized particular concern regarding injectable products, which bypass the body's natural defenses and carry risks of serious harm including infection and systemic toxicity.

**Regulatory Citations and Meaning**

The violations cite sections 301(d) and 505(a) of the Federal Food, Drug, and Cosmetic Act (21 U.S.C. 331(d) and 355(a)), along with the definition of "new drugs" under section 201(p) (21 U.S.C. 321(p)). These provisions require FDA approval before marketing drugs intended to diagnose, treat, mitigate, or prevent disease, or affect body structure or function. The company's website labeling explicitly described therapeutic uses—glucose regulation for diabetes, weight loss, cardiovascular health, mitochondrial function, and sexual dysfunction—establishing drug intent despite "research use only" disclaimers. The FDA determined these products lack recognized safety and efficacy and possess no approved New Drug Applications.

**Response Timeline and Industry Watchpoints**

Tex Peptides must submit a written response within 15 business days to FDAAdvisory@fda.gov detailing corrective actions and preventive measures. Compliance officers monitoring similar operations should expect continued FDA enforcement against online peptide vendors using disclaimer language to circumvent approval requirements. Regulatory risk intensifies given injectable product delivery and direct health claims. The warning letter signals FDA's focus on unapproved GLP-1 receptor agonists and emerging peptides marketed through digital channels. Non-compliance may trigger seizure or injunction actions.

Severity context

Critical severity. Typically reserved for data integrity, sterile-product CGMP, or repeat violations — matters that historically precede injunctions, consent decrees, or import alerts.

Regulatory background

Unapproved-drug letters cite 21 USC 355 (NDA requirement) or 21 USC 331(d) (introduction into interstate commerce). FDA increasingly applies these provisions to homeopathic products, kratom, and certain compounded preparations.

What peer compliance teams typically do next

Most compliance officers at peer companies use a Warning Letter against a named entity as a checklist for their own CAPA program. Common steps: pull the verbatim FDA letter; map each cited 21 CFR section against the team’s SOP library; confirm CAPA coverage; brief the QMR (Quality Management Review) on whether the cited subject matter is in scope for the next internal audit. The 15-business-day response window applies to the cited entity, not to peers — but a documented internal review against the cited subjects is what regulators expect to see if a peer is later inspected on the same topic.

Failure to adequately address violations may result in regulatory or legal action without further notice including, without limitation, seizure and injunction. These products are especially concerning from a public health perspective because injectable drug products can pose risks of serious harm to users. Injectable products are delivered directly into the body, sometimes directly into the bloodstream, and therefore, bypass some of the body’s key defenses against toxins and microorganisms that can lead to serious and life-threatening conditions.
