AOD-9604: Fat-metabolizing fragment of human growth hormone without growth-promoting effects. Typical dose 250-500 mcg. HGH Fragment 176-191: The unmodified C-terminal fragment of growth hormone — the original lipolytic peptide. Typical dose 250-500 mcg. Both fall under the Weight Management category.
Stacking AOD-9604 with HGH Fragment 176-191 is a protocol-design question best raised with a clinician — it depends on your goal, current bloodwork, and whether both peptides target overlapping mechanisms. Both peptides should be tracked independently with separate injection sites and timing. PinnyPeptide supports multi-peptide stacks with automatic injection site rotation.
AOD-9604 is typically dosed: Once daily (SubQ) for Fat loss and body composition. HGH Fragment 176-191 is typically dosed: Once daily, morning, on an empty stomach (SubQ) for Fat loss / body recomposition; Twice daily (morning + pre-cardio), fasted for Split-dose protocol for stubborn fat.
AOD-9604: Not FDA approved as a drug. Granted GRAS status as a food additive in 2014. HGH Fragment 176-191: Not FDA approved. Distinct from AOD-9604, which holds GRAS status as a food additive.
