Functional medicine will usually prioritize: Identifying food triggers and patterns Supporting digestion and motility Looking for nutrient deficiencies Considering stool testing when appropriate Addressing stress physiology, since gut symptoms are strongly connected to it BPC-157 might come up, but it should not replace foundational gut work
Others use continuous daily dosing

Avoid the injection if you're allergic to any component of its formulation

Decision Framework: Which to Choose The choice between AOD-9604 and tesamorelin depends entirely on whether the research wants to engage the GH axis or isolate specific GH effects: Choose AOD-9604 if: Research focuses specifically on lipolytic activity without GH receptor engagement Studies want to avoid IGF-1 elevation and broader GH effects The receptor-independent mechanism is part of the research question Fat metabolism research without confounding GH signaling effects is the goal Choose tesamorelin if: Research focuses on GHRH receptor pharmacology or pituitary GH axis Studies want full GH axis activation including IGF-1 elevation The natural pulsatile GH release pattern is biologically relevant DPP-4-resistant GHRH analog mechanism is the research focus Choose neither (or both) if: Research focuses on different aspects of GH biology Comparative research between upstream and downstream GH peptides is the goal Other GH-related compounds (sermorelin, CJC-1295, ipamorelin) are more relevant see Sermorelin, CJC-1295, and Ipamorelin Research Overview Quality Considerations Both peptides share the same quality framework: Manufactured via Solid-Phase Peptide Synthesis with synthetic amino acids Specific N-terminal modifications incorporated as synthesis steps No animal-derived materials Independent third-party testing by Janoshik Analytical 99% HPLC purity per peptide Mass spectrometry identity confirmation (particularly important for confirming the modifications) For complete quality framework coverage, see How to Verify Peptide Quality and How to Read a Janoshik COA

(2001) investigated AOD9604 in obese Zucker rats and observed that chronic administration was associated with reduced body weight gain without changes in IGF-1 levels or glucose tolerance, distinguishing its activity profile from that of full-length growth hormone [1]
