01Mechanism of Action

Parameter
AOD-9604
GHRP-6
Primary target
β3-adrenergic receptor (proposed)Ng 2008
Ghrelin receptor (GHS-R1a)Bowers 1990
Pathway
β3-AR activation → cAMP → hormone-sensitive lipase activation → triglyceride breakdown to FFA + glycerolNg 2008
GHS-R1a → Gαq → Ca²⁺ → GH release; central appetite driveBowers 2002
Downstream effect
Lipolysis of adipose tissue triglycerides; FFA release for oxidation; minimal IGF-1 / insulin impactHeffernan 2001
GH pulse + strong appetite stimulation; modest IGF-1 elevationBowers 2002
Feedback intact?
No GH-axis or IGF-1 feedback
Origin
Synthetic modified C-terminal hexadecapeptide fragment of human GH (176-191) with N-terminal Tyr substitutionNg 2008
Synthetic hexapeptide; first-generation GHRP from Bowers groupBowers 1990
Antibody development

05Administration Protocol

Parameter
AOD-9604
GHRP-6
1. Reconstitution
Add 1 mL bacteriostatic water to 2 mg vial → 2 mg/mL = 200 mcg per 0.1 mL.
Add 2 mL bacteriostatic water to 5 mg vial → 2.5 mg/mL.
2. Injection site
SQ — abdomen preferred. Rotate sites.
SQ — abdomen. Rotate sites.
3. Timing
Morning, fasted, ideally pre-cardio for amplified fat oxidation.
Pre-meal for appetite support; pre-sleep for GH alignment.
4. Storage
Lyophilised: room temp, light-protected. Reconstituted: refrigerate, ≤30 days.

06Stack Synergy

AOD-9604
+ MOTS-c
Moderate
View MOTS-c

AOD-9604 mobilises FFAs from adipose via β3-AR; MOTS-c upregulates AMPK / PGC-1α / FAO machinery so that mobilised FFAs are efficiently oxidised. The pathways are sequential — supply (AOD) plus demand (MOTS-c) — and produce more durable lipolytic effects than either alone in anecdotal protocols.

AOD-9604
250–300 mcg SQ · morning fasted (daily)
MOTS-c
5 mg SQ · 2–3× per week (pre-workout)
Primary benefit
Fat mobilisation + mitochondrial oxidation, no IGF-1 concern
GHRP-6
— no documented stacks
