Unlawful Sale of Unapproved and Misbranded Drugs to United States Consumers Over the Internet

What FDA cited

FDA's letter of September 9, 2025 cites SemaBio for false or misleading claims about the drugs it sells, under the subject line "Unlawful Sale of Unapproved and Misbranded Drugs to United States Consumers Over the Internet". The GLP-1 drugs it names: semaglutide.

In FDA’s words:
As described below, your claim concerning compounded semaglutide products is false or misleading under sections 502(a) and 502(bb) of the Federal Food, Drug, and Cosmetic Act (FDCA) [21 U.S.C. §§ 352(a) and 352(bb)], resulting in products being introduced or delivered for introduction into interstate commerce in violation of section 301(a) of the FDCA [21 U.S.C. § 331(a)]. … Your claim implies that your products are the same as an FDA-approved product when they are not.

How this letter sits against the other 159

Our reading, from the 160 letters on this register — not part of the FDA’s document.

The FDA issued 59 of the 160 letters on this register on the same day, September 9, 2025, the largest single action in our records. This company was part of a sweep rather than singled out. That does not make the letter less serious, but it does mean the agency was acting against a practice across the market, not against one seller's conduct alone.

A warning letter is the agency putting a company on notice, not a court finding and not a ban. What it is worth to you is in what it alleges, so read the original on fda.gov rather than the fact that one exists.

The FDA objected to how this firm described compounded semaglutide. For what actually differs from the brand drug: Compounded semaglutide vs Ozempic and Wegovy: what is actually different.

FDA’s letter of September 9, 2025 to SimpleRx also cites its recipient for false or misleading claims about the drugs it sells.

What FDA warning letters mean

It is the agency writing to a company to say it believes something that company is doing breaks the Federal Food, Drug, and Cosmetic Act — usually a claim on a website, a labeling choice, or how a drug is being made. The company has about fifteen working days to write back.

Read carefully what it is not. It is not a recall, not a criminal charge, and not a court deciding anyone broke the law. It is the regulator opening a file. Companies frequently answer a letter, fix what was cited, and carry on trading, and when FDA accepts that it can issue a close-out letter. We do not track close-outs, so the presence of a letter on this page tells you what FDA said on one date — not where the matter stands today. Ask the company; they will usually tell you, and how they answer is informative in itself.

Across this market the same three citations recur: claiming a compounded product is equivalent to an approved one, labeling that misleads, and compounding from bulk substances FDA has not cleared under sections 503A and 503B. If you are reading a letter here, it is probably one of those.

Editorial Disclaimer

This is a public communication from a regulator, and by itself it settles nothing about whether the company broke any law. Corrective action is a common response, and a fair number of letters end in a close-out. Read the whole thing on fda.gov through the link above rather than taking our excerpt as the full picture.
