AOD-9604 & CJC-1295 & Ipamorelin (Stack) vs P21

A detailed comparison to help you understand the differences and choose the right peptide for your research goals.

AOD-9604 & CJC-1295 & Ipamorelin (Stack)

A targeted fat loss stack combining AOD-9604 (the fat-burning fragment of HGH) with CJC-1295 and Ipamorelin for comprehensive body recomposition. This blend addresses fat loss directly while supporting lean mass through GH optimization.

Side-by-Side Comparison

AspectAOD-9604 & CJC-1295 & Ipamorelin (Stack)P21
MechanismAOD-9604 stimulates lipolysis and inhibits lipogenesis without affecting IGF-1 or blood glucose. CJC-1295 and Ipamorelin provide sustained and pulsatile GH release to support metabolism and lean tissue. The combination targets fat loss through multiple mechanisms while preserving muscle.Inhibits glycogen synthase kinase-3β (GSK-3β) and activates CREB signaling pathway. This promotes BDNF expression, neurogenesis in the hippocampus, and synaptic plasticity.
Typical DosageTypical protocol: AOD-9604 200-400mcg, CJC-1295 100-200mcg, Ipamorelin 100-200mcg daily. Usually administered in the morning fasted or before exercise.Research protocols typically use 1-5mg administered intranasally or subcutaneously. Often used in cycles of 2-4 weeks.
AdministrationSubcutaneous injection. Best administered fasted to maximize fat-burning effects. Can be taken as a pre-mixed blend or separate injections. Cycles typically run 8-16 weeks.Can be administered intranasally for direct CNS access or subcutaneously. Best used cyclically rather than continuously.
Side EffectsMild injection site reactions, headache, nausea. Generally well-tolerated as AOD-9604 lacks many HGH side effects.Limited data. Reported effects include mild headache, temporary brain fog during initial use, and fatigue.
