What AOD-9604 Is
AOD-9604 is a fragment of growth hormone that keeps the fat-burning signal without the growth effects. It is taken as a daily subcutaneous injection, 8 to 12 weeks, and most people notice it in 4 to 8 weeks.
What Tesamorelin Is
Tesamorelin is a GHRH analog with specific data on abdominal fat; an FDA-approved version exists for one HIV-related use. It is taken as a nightly subcutaneous injection; needs IGF-1 labs, and most people notice it in 2 to 3 months.

Pick AOD-9604 If
Your main concern is stubborn fat with diet already in place, and no interest in a GLP-1. It is the right call when the goal is fat loss without appetite suppression and you want the simpler, more targeted option.
Pick Tesamorelin If
Your main concern is stubborn abdominal fat specifically. It is the right call when the goal is visceral (belly) fat and recovery.
Can You Combine Them?
Rarely needed. Both target fat; tesamorelin is the stronger choice for belly fat specifically, AOD-9604 the gentler all-over option.
