In real-world practice, the stacking conversation often blurs three very different categories: FDA-approved peptide drugs (e.g., tesamorelin for HIV-associated lipodystrophymore on this below) (FDA Access Data) Non-approved peptides sometimes discussed in compounding/wellness circles (e.g., AOD-9604, BPC-157, CJC-1295, ipamorelin) Unregulated research use only products sold online (which often have the worst quality and highest risk) That distinction matters because safety isnt just about pharmacologyits also about purity, stability, sterility, and labeling accuracy
