01Mechanism of Action

Parameter
AOD-9604
Selank
Primary target
β3-adrenergic receptor (proposed)Ng 2008
Monoamine system (serotonin / GABA modulation) + immunomodulation via tuftsin domainZaderej 2014
Pathway
β3-AR activation → cAMP → hormone-sensitive lipase activation → triglyceride breakdown to FFA + glycerolNg 2008
Tuftsin-derived immune signaling + CNS monoamine modulation → reduced anxiety + improved mood / cognitionMedvedev 2007
Downstream effect
Lipolysis of adipose tissue triglycerides; FFA release for oxidation; minimal IGF-1 / insulin impactHeffernan 2001
Anxiolytic + cognitive enhancement; immunomodulation via increased IL-6 + IFN-γMedvedev 2007Zaderej 2014
Feedback intact?
No GH-axis or IGF-1 feedback
No GABA-receptor binding; no dependence reportedMedvedev 2007
Origin
Synthetic modified C-terminal hexadecapeptide fragment of human GH (176-191) with N-terminal Tyr substitutionNg 2008
Synthetic 7-AA peptide derived from human tuftsin (immune-system tetrapeptide)Zaderej 2014

04Side Effects & Safety

Parameter
AOD-9604
Selank
Injection site reaction
Mild erythema
GI symptoms
Rare mild nausea
Cardiovascular
Possible mild HR increase via β3-AR (theoretical β1 cross-reactivity)
IGF-1 elevation
None — designed to lack GH-axis activityHeffernan 2001
Insulin sensitivity
Neutral — no glucose impairmentHeffernan 2001
Cancer risk
No GH/IGF-1 axis activity → lower theoretical risk vs HGH
Pregnancy / OB
Avoid
Avoid — insufficient data
Nasal irritation
Mild burning or congestion (transient)
Sedation
None — distinct from benzodiazepinesMedvedev 2007
Dependence / withdrawal
None reported in clinical useZaderej 2014
Cognitive impairment
None — opposite effect (enhancement)
Allergic reaction
Rare hypersensitivity
Long-term safety
Limited Western RCT data

05Administration Protocol

Parameter
AOD-9604
Selank
1. Reconstitution
Add 1 mL bacteriostatic water to 2 mg vial → 2 mg/mL = 200 mcg per 0.1 mL.
Pre-formulated nasal spray (commercial) or research vial reconstituted with bacteriostatic water.
2. Injection site
SQ — abdomen preferred. Rotate sites.
Intranasal — 1–3 sprays per nostril per dose. Tilt head slightly back.
3. Timing
Morning, fasted, ideally pre-cardio for amplified fat oxidation.
Morning + early afternoon for cognitive demand; PRN for acute anxiety.
4. Storage
Lyophilised: room temp, light-protected. Reconstituted: refrigerate, ≤30 days.
Refrigerate after reconstitution; ≤30 days. Light-protected.
5. Needle
29–31G, 4–8 mm insulin syringe.
Avoid co-administration with strong sedatives or other anxiolytics initially.

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
