Is Deadpool blend legal in the United States?

A three-peptide repair vial, most often 10 mg each of BPC-157, TB-500 and KPV, sold as KLOW without the copper. No study has tested the three together in any species. The name is the real hazard: different vendors sell at least three different formulas under it, including one that is KLOW relabelled and one built on a different peptide entirely, so the word on the label does not identify the contents.

Deadpool is a marketing name, not a formula. Search the vendors and you find the same word on a 30 mg vial holding 10 mg each of BPC-157, TB-500 and KPV, on a 20 mg vial split 10 mg TB-500, 5 mg BPC-157 and 5 mg KPV, on a copper-loaded vial that is KLOW under another name, and on a three-peptide vial built around cartalax rather than KPV.

Mechanism: Assumed additive, and assumed is doing the work. BPC-157 acts through the angiogenic and tissue repair pathways described on its own page, almost entirely in rodents.

Regulatory history: Not approved. No regulator has evaluated the combination. FDA staff evaluated BPC-157 alone for the July 2026 Pharmacy Compounding Advisory Committee and found no adequate human data.

Approves prescription drugs by indication and polices unapproved products, including peptides sold online. Compounding pharmacies may prepare some compounds under a prescription when the FDA places them on a permitted bulk-substances category.

The classification above is the The Longevity Archive reading of U.S. Food and Drug Administration listings for Deadpool blend at the reviewed date, not a legal opinion. Rules change, and importing, prescribing and possessing a compound can each be treated differently. Check the regulator directly before acting on anything here.
