Supporting your stack with training and nutrition: Peptides amplify your efforts, they dont replace them
One sign that you lack enough B12 may be a swollen, inflamed tongue
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
