What it alleges
Claims on skinnyrx.com that compounded products give the same active ingredient as name-brand GLP-1 medications are false or misleading.
The letter quotes 2 claims from the website it reviewed, reproduced here exactly as the letter prints them, including the agency's own elisions.
“Get access to the same active ingredient as name-brand GLP-1 medications”
“from the same family as GLP-1 treatments like Mounjaro® and Zepbound®”
A quoted claim is evidence of what a page said when the agency read it. It is not evidence of what the page says today, and this site records the seller's current pages separately, on the seller record, with their own date.
The sections cited are 502(a), 502(bb), 301(a), 301(c), 503(b)(1), 503(b)(2). Section 502(a) makes a drug misbranded where its labeling is false or misleading, and section 502(bb) extends that to the advertising or promotion of a compounded drug. Both are labeling and advertising provisions.
How it was attributed
The letter reviews skinnyrx.com, prints support@skinnyrx.com, and gives the Sacramento street address the seller prints in its own terms and privacy policy. A letter is filed under an operating entity, and a company may trade under names that appear nowhere in it, so the screen is run against the entity and the address rather than against the brand on the storefront. A name resemblance is never the test, because attaching one company's enforcement record to another is a worse error than missing a disclosure.
What the ledger records since
SkinnyRx is recorded against criterion S8, enforcement status as PASS. The basis reads: FDA warning letter 717989, February 2026, names Lean Rx, Inc. doing business as SkinnyRx at the Sacramento address this site prints, and cites claims of the same active ingredient as an approved drug. No FDA action has halted the business, and the seller still trades. The storefront was reachable and trading when the record was last read.
The index carries no close-out letter for it. When the index was read in September 2026 it held 3,677 letters and 417 of them carried a close-out letter, so the column is populated and an empty cell is a reading rather than a gap. A letter that has been neither closed out nor followed by an action is the ordinary state of a warning letter.
Why this is not a disqualification
A warning letter identifies a concern, requests a response, and states that failure to address the violations may result in legal action, including seizure and injunction. Those actions are what criterion S8 fails on. The letter is the notice that precedes them and it is not one of them, so this ledger records it in full, dates it, links it, and leaves the seller listed and linked exactly as a seller with no letter.
