Peptide email compliance check

What it checks

Each result is sorted into one of three levels, and every one names its source and quotes it word for word.

• Stop. Language regulators and platforms treat as a drug claim: human use, doses and schedules, preparation supplies, “treats, cures or prevents”, named conditions, weight loss, performance and therapeutic wording. The sources are the 2026 FDA warning letters to peptide sellers, 21 CFR 201.128, and the Brevo, Klaviyo and ActiveCampaign policies.
• Caution. Words that usually lead to a claim (“results”, “benefits”, “effective”, “clinically proven”, “FDA approved”), pharmaceutical wording, language about bought or scraped lists, and for emails, a missing unsubscribe link or postal address under CAN-SPAM.
• Note. Notes are our own style advice, not a law or a platform rule. They flag wording that tends to read as filler. We also note when no research-use line is present.

The FDA pattern comes from the letters themselves. We walk through all eleven in FDA warning letters to peptide sellers in 2026. The platform clauses come from our platform policy tracker, which quotes 13 policies with links and dates. The CAN-SPAM rules come from the FTC compliance guide for business.

What it does not do

It does not read meaning. It matches phrases, so it will miss a claim written in words it does not know, and it will sometimes flag a word used innocently, such as “results” in a lab report. It does not look at images, links, landing pages or the products you sell next to each other, all of which the FDA letters cite. It does not check your consent records, sending domain or deliverability.

It also does not teach evasion. Every fix suggestion removes a claim or replaces it with a fact: identity, purity, lot, storage, price, a certificate of analysis. We will never suggest a synonym, a misspelling or an image that keeps a claim while hiding it from a reviewer. A hidden claim is still a claim, and the 2026 letters treated hedged wording as evidence.

How to use the report

Start with every Stop. If a sentence only works with the flagged word in it, the sentence is the problem, so cut it rather than reword it. Then read the Cautions and decide which are true statements of fact. Use “Copy report” to paste the findings into a ticket or send them to whoever signs off your copy.

Run the check on your automated flows too, not only campaigns. A welcome series written two years ago still sends every day. For the sending side, see email marketing for peptide brands: Amino Engine runs flows and campaigns for peptide brands on mail servers we own.
