FTC — Endorsement & Testimonial Substantiation (§255 Guides)
16 CFR §255
The FTC Endorsement & Testimonial Guides (16 CFR §255) require that advertising claims based on customer testimonials be substantiated. Quantified results ("lost 20 lbs"), time-bound results ("in 30 days"), and before/after framing all need a typical-results disclosure unless the advertiser can show the result is what consumers generally achieve. What it means for you: when copy uses a testimonial-style result, pair it with a "results may vary" / "individual results may differ" disclosure adjacent to the claim. This is a reference summary, not legal advice — confirm with counsel.
