HHS published a draft compounding policy on October 30, 2026. It covers only 6 peptides, one per product, made for a patient with a prescription. Neither tesamorelin nor ipamorelin is on that list, and the policy does not cover blends like tesamorelin + ipamorelin. It is a draft and gives no legal rights.3

No study has checked whether tesamorelin + ipamorelin is safe.
Tesamorelin has 43 safety results, including 34 from people. Ipamorelin has 1 safety result, and it comes from people. Each peptide guide lists its own safety results.
Quality also changes from product to product. A 2026 preprint looked at 6,441 lab tests of research peptides sold online. Purity and the amount of peptide in each vial varied widely1.
