slendid.com returned a live storefront when we checked in August 2026, still selling online GLP-1 prescriptions with a client portal and a published phone number. We did not review every page on the site.

Four words drew this letter, which is the most useful thing about it. "Clinically proven" is doing a specific job in a price comparison: it invites you to treat a cheaper compounded vial and an approved brand as interchangeable, so that the only remaining difference is the number. FDA's point is that the trials behind that phrase were run on the approved product, not on the compounded one you would be buying. That does not mean the medication does not work or that the company misled anyone deliberately — it means the phrase carries more authority than the product behind it has earned. Read the price for what it is, and read "clinically proven" as marketing copy rather than a regulatory status.

As of August 2026, FDA’s public tracking for this letter does not show a logged company response. Companies are not required to make a response public, and FDA does not always update this field promptly — this is not evidence Slendid failed to respond.
