How this letter sits against the other 159
Our reading, from the 160 letters on this register — not part of the FDA’s document.
No other letter on this register carries the date October 30, 2026. The agency acted against this company on its own that day, which is uncommon here — most of the letters we hold arrived in sweeps.
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.
For how this charge fits the wider run of GLP-1 letters: What the FDA's GLP-1 warning letters say about this market.
FDA’s letter of September 9, 2025 to All American Wellness also cites its recipient for false or misleading claims about the drugs it sells.

This letter notifies you of our concerns and provides you an opportunity to address them. If you have information that you believe demonstrates that your products are not in violation of the FD&C Act and FDA regulations, include that information for our consideration. If you cannot completely address this matter within fifteen (15) working days, state the reason for the delay and the time within which you will do so.
If you are not located in the U.S., please note that drug products that appear to be misbranded may be detained or refused admission. We may advise the appropriate regulatory officials in the country from which you operate that your drug products referenced above appear to be misbranded drug products that cannot be legally sold to consumers in the U.S.
1 The semaglutide and tirzepatide products offered on your website and associated social media platforms are drugs within the meaning of section 201(g) of the FD&C Act [21 U.S.C. § 321(g)] because they are intended for use in the diagnosis, cure, mitigation, treatment, or prevention of diseases and/or because they are intended to affect the structure or any function of the body. Further, they are “new drugs” within the meaning of section 201(p) of the FD&C Act [21 U.S.C. § 321(p)] because they are not generally recognized as safe and effective for their labeled uses.
2 You are advised to reassess your advertisements and promotional materials across all platforms, including television and social media.

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.
