Three Categories Reviewed:

  • Sermorelin
  • Tesamorelin
  • Tirzepatide

——-

  • GHK-Cu (skin benefits – approved for Topical only)
  • NAD+ – mitochondria / energy / inflammation

2. Legal to Purchase / Not allowed for Compounding

These are legal to purchase for research purposes but have not been approved for compounding in a pharmacy. This often means they don’t have enough information or that no application has been made.

The reason you may see a few of them available at compounding pharmacies is likely because they are operating under State-level interpretations, but they are not Federally approved for compounding.
