Every flag here is something a storefront publishes about itself, and each one takes away a check a buyer could otherwise run. A buyer facing all six has nothing left to check with.

The index

Copy on what a compound does in a person

The disclaimer in the footer does not answer the product page above it. Under 21 CFR 201.128, read 2026-09-13, intended use is shown by "labeling claims, advertising matter, or oral or written statements." In a warning letter dated August 24, 2026, MARCS-CMS 735127, FDA found the products to be drugs and wrote, in a footnote to that finding, that "Despite statements on your product labeling marketing your products for 'research use only'" the "evidence obtained from your website establishes that your products are intended to be drugs for human use." The label did no work. A seller writing outcome claims has put its catalog inside the definition of an unapproved new drug.

No batch-specific certificate

A certificate is a claim about one batch. ICH Q7, Step 4 of 10 November 2000, read 2026-09-13, is written for pharmaceutical ingredients in human drug products, not research-use sellers, but it is the reference for what a batch certificate carries: issue per batch on request (11.40); the batch number and release date (11.41); each test with its limits and figures (11.42); a date, a signature and the manufacturer's name, address and telephone number (11.43); and, on a certificate a broker or agent issues, the name, address and telephone number of the laboratory that ran the analysis (11.44). One document for a whole catalog carries none of that. The missing batch number removes the cross-check: a lot code on the vial matching a lot code on a dated report from a named laboratory is the only thread from powder to figure, and a purity figure by HPLC with no lot beside it describes some run on some day.

Cryptocurrency or payment-app only

Regulation Z, 12 CFR 1026.13(a)(3), read 2026-09-13, counts as a billing error on open-end credit, a credit card at these checkouts, a charge for property "not delivered to the consumer or the consumer's designee as agreed." A debit card runs under Regulation E, whose error list at 12 CFR 1005.11(a)(1) has no entry for goods not delivered; under 12 CFR 1005.2(m) an unauthorized transfer is one "initiated by a person other than the consumer," so a payment the buyer sent is not one. The FTC's consumer advice, read the same day, says cryptocurrency payments "typically are not reversible," and its July 22, 2026 alert puts 2025 losses to scams paid by bank transfer and cryptocurrency above $4 billion. A discount on the irreversible option is a price put on the dispute right.

Sales only in a messaging app

The FTC's Mail, Internet, or Telephone Order Merchandise Rule, 16 CFR Part 435, read 2026-09-13, requires shipment within the advertised time or 30 days and, failing that, the buyer's consent to a delay or a refund. A buyer can hold a seller to that only if there is a seller to hold: a legal name, a postal address, published terms. A handle holds none of those. Of the 126 supplier records in this publication's ledger, read 2026-09-13, 12 mention Telegram, WhatsApp or Discord in their notes for any reason: one names Telegram only to refuse bank-detail changes over it, one describes a lookalike domain taking orders by WhatsApp, and one describes a product page offering its certificate by pre-filled WhatsApp message in place of a document. A contact link beside a working storefront is not this flag; the storefront that is only the handle is.

A price far under every peer

A price pays for synthesis, purification, per-lot testing and standing behind delivery, and one far under every peer is a reason to ask which was dropped. The FTC's online shopping advice, read 2026-09-13, says brand-name goods at bargain prices "could be counterfeit or stolen"; the cheapest way to undercut peers who publish lot certificates is to stop paying for them. In this publication's ledger, read 2026-09-13, 46 records carry a single-vial price for retatrutide at 10 mg, read August 17 to 26, 2026: $30 to $200. A lot report whose number comes back from the laboratory makes a low price a low price: some laboratories run a lookup on their own site that returns a report from the number or key printed on it, and a report with no such route rests on the seller's word.

Reviews gated by satisfaction

Gating is asking for public reviews only from buyers the seller expects to be positive. The FTC's Endorsement Guides, 16 CFR 255.2(d), read 2026-09-13, say an advertiser procuring, suppressing or organizing reviews should not distort what consumers think, and Example 11 describes inviting only purchasers who gave very positive feedback to post, which "may be an unfair or deceptive practice" if the posted reviews come out substantially more positive. Gating is Example 11 territory; 16 CFR 465.7, in force since October 21, 2024, reaches a seller that also suppresses negative reviews while presenting the rest as most or all submitted. The sign is a review section a buyer cannot post to uninvited, or a satisfaction prompt placed before the link to a public review site; a third-party review page open to any buyer clears it. A score filtered by the party it rates says nothing about the share of orders that went wrong.

What the index cannot tell you

Every flag here is about what a seller publishes, not what is in a vial. A storefront can carry none of the six and ship the wrong material, and can carry one through circumstance: a seller that lost card processing has the same checkout as one that never wanted it. No supplier was examined and none is named. A flag is a missing check, never a finding of fraud.

Each flag is cheap for a buyer to check. The ones that stay are the finding.
