Examines the boom in interest around peptide drugs and how gray‑market suppliers exploit that demand with AI-generated storefronts and review sites. Peptides require non-oral delivery, so buyers rely on online vendors and forums; the piece follows a few popular-looking examples and shows they are polished façades. A site posing as a reputable vendor displays fake TrustPilot-like reviews, and a purported review forum contains superficially convincing threads that are entirely machine-generated. The overall argument is that readily available LLMs have made it trivial to build convincing but empty ecosystems that persuade people to buy unvetted chemical products.

Provides concrete forensic findings that expose the deception: hosting in an offshore, DMCA‑friendly jurisdiction; vendor pages all pointing to Chinese peptide suppliers; forum metadata anomalies (every thread exactly five posts, many timestamps predating domain registration, posts authored before accounts existed); and a separate “analysis” site registered minutes apart sharing the same Cloudflare and registrar. A telling robots.txt entry explicitly welcomes LLM crawlers, indicating the sites are designed to be scraped and folded into search and model training rather than to inform humans. The takeaway is to cultivate skill at spotting AI‑generated content and to rely on AI‑detection tools and cautious browsing when researching high‑risk suppliers.
