Updates & investigations
Peptide news, investigations and regulatory updates
Dated research and regulatory records, each tied to its sources. Follow FDA decisions, enforcement cases, MHRA advertising guidance and the annual WADA Prohibited List without treating an allegation, recommendation or guidance note as more than it is.
The update desk records the source, event date, practical change and unresolved next step for each item.
Each log separates an advisory recommendation from an agency decision, guidance from legislation, and a named example from the wider class wording that may govern a substance.

How the logs are maintained
Every entry names the issuing body or court, source date and date checked. We update a record when an official source changes, then identify the pages whose wording or status may need review.
A source can change without changing a conclusion. When it does, the log says so. Substantive corrections also appear in the public corrections record.
What an update record can establish

|---|---|---|
| FDA advisory review | Agenda, staff analysis, committee questions and reported recommendation | FDA approval, a final rule or a binding compounding decision |
| MHRA guidance log | Current official interpretation and advertising guidance | A court ruling or a product-specific legal determination |
| WADA annual list | Current prohibited classes, examples and effective date | Permission for an unnamed or differently labelled substance |
| Enforcement case | Offences, court orders and source-attributed case facts | The conduct of every seller or the composition of an untested product |
