Is thymalin legal in the US?

This site's US legal-status field for thymalin is not approved, research use only. It is not an FDA approved drug and was not among the seven peptides the FDA Pharmacy Compounding Advisory Committee reviewed in July 2026. UK: not licensed. Australia: not approved, prohibited in sport (WADA). Canada: not approved. Sub-national detail is not in this dataset.

Educational use only. This database summarizes published research and is not medical advice. Where a dose appears it is a record of what a trial or clinic ran, or what people describe doing, with its source attached. Nothing here is a recommendation for personal use.

Part of more absences and national fields. Further harvested questions after the first names-and-absences set: more side effects the citations did not count, compounding formulas this catalogue does not hold, national legal-status fields for compounds that only have those four countries, trial windows rather than an onset clock, and named prescription combinations with no interaction table.
