Peptides · Compliance library

The peptide category, sourced.

Ten sourced articles on the business and regulatory side of peptides: platform policy, FDA compounding, research-use framing, FTC substantiation, certification, the GLP-1 timeline, AI crawler policy, the supplement question, and the production method behind all of it.

Every article cites the primary record, with dates: FDA pages and warning letters, platform policy documents, and Google's own documentation. No biology, no product claims, and no legal advice. This library exists because in a vertical where paid advertising is closed by written policy, being the most accurate source in the category is the growth strategy.

Platform policy
