01Mechanism of Action

Parameter
AOD-9604
Semax
Primary target
β3-adrenergic receptor (proposed)Ng 2008
BDNF / NGF expression + monoamine modulationKaplan 2017
Pathway
β3-AR activation → cAMP → hormone-sensitive lipase activation → triglyceride breakdown to FFA + glycerolNg 2008
↑ BDNF + NGF synthesis + 5-HT modulation → neuroplasticity + anxiolysis + cognitive enhancementKaplan 2017
Downstream effect
Lipolysis of adipose tissue triglycerides; FFA release for oxidation; minimal IGF-1 / insulin impactHeffernan 2001
Improved memory + attention; reduced anxiety; neuroprotection in ischemiaKaplan 2017
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 7-AA peptide derived from ACTH(4-7) with C-terminal Pro-Gly-Pro stabilising tailKaplan 2017

04Side Effects & Safety

Parameter
AOD-9604
Semax
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

05Administration Protocol

Parameter
AOD-9604
Semax
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 — 2–3 sprays per nostril per dose. Tilt head slightly back.
3. Timing
Morning, fasted, ideally pre-cardio for amplified fat oxidation.
Morning + early afternoon. Avoid evening (sleep disruption).
4. Storage
Lyophilised: room temp, light-protected. Reconstituted: refrigerate, ≤30 days.
Refrigerate after reconstitution; light-protected.
5. Needle
29–31G, 4–8 mm insulin syringe.
Cycle on/off to avoid neurochemical adaptation.

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
Semax
+ Selank
Moderate
View Selank

Semax (cognitive enhancer, BDNF/NGF) and Selank (anxiolytic + immune) form the canonical Russian "neuro stack" — both intranasal peptide bioregulators with complementary axes. Semax for cognitive demand; Selank for stress mitigation.

Semax
200–600 mcg intranasal · morning + afternoon
Selank
150–300 mcg intranasal · midday + early evening
Primary benefit
Cognitive enhancement + stress mitigation
