Tools (4)

• check_legal_status293 tok

  The legal status of one peptide, GLP-1 drug or seller-named blend (KLOW, GLOW, the Wolverine stack) in the United States (FDA), Australia (TGA), the UK (MHRA), the EU (EMA), Canada (Health Canada), Brazil (ANVISA, where covered) and sport (WADA), or in the one place you name. Returns each status with a plain-language note; for the U.S. also the full answer (compounding rules, the latest FDA advisory vote, the next dated event), plus primary sources and the date it was last verified.

• recent_changes203 tok

  Dated regulatory events from the Peptlas changelog, newest first: FDA advisory votes, list changes, comment deadlines, warning letters. Optionally for one compound (or a blend, meaning all its ingredients) or since a date. Use it for "what changed" or "any news on BPC-157".

• status_in_place181 tok

  Every tracked peptide in one place, with its status and a note: use it for "which peptides are legal in Australia" or "what does WADA ban". Optionally only one status.

• list_compounds118 tok

  The 26 compounds and 3 blends Peptlas tracks, with the names people search by (brands, codes, street names), each U.S. status and its page. Use it to see what is covered.
