01Mechanism of Action

Parameter

AOD-9604

Dermorphin

Primary target

β3-adrenergic receptor (proposed)Ng 2000

μ-opioid receptors (central and peripheral)Negri 1992 Steel 2014

Pathway

β3-AR activation → cAMP → hormone-sensitive lipase activation → triglyceride breakdown to FFA + glycerolNg 2000

μ-receptor activation → G-protein coupling → adenylyl cyclase inhibition → neuronal hyperpolarization

Downstream effect

Lipolysis of adipose tissue triglycerides; FFA release for oxidation; minimal IGF-1 / insulin impactHeffernan 2001

Potent analgesia, reduced nociceptive signaling, opioid-mediated CNS and peripheral effects

Feedback intact?

No GH-axis or IGF-1 feedback

N/A — exogenous opioid agonist

Origin

05Administration Protocol

Parameter

AOD-9604

Dermorphin

1. Reconstitution

Add 1 mL bacteriostatic water to 2 mg vial → 2 mg/mL = 200 mcg per 0.1 mL.

Dermorphin is a controlled substance in many jurisdictions and is not approved for human use. Possession, synthesis, or distribution may be illegal. Use is restricted to licensed research settings under institutional review.

2. Injection site

SQ — abdomen preferred. Rotate sites.

In rodent models, intracerebroventricular (ICV) or intrathecal injection is used at nanomolar to picomolar concentrations. Subcutaneous administration also documented. All protocols require IACUC approval.

3. Timing

Morning, fasted, ideally pre-cardio for amplified fat oxidation.

High-throughput LC-MS/MS screens developed for anti-doping programs detect dermorphin and 17 related peptides in equine and human urine/plasma at limits as low as 5 pg/mL.Steel 2014

4. Storage

Lyophilised: room temp, light-protected. Reconstituted: refrigerate, ≤30 days.

Application of Phyllomedusa bicolor skin secretions to superficial burns. Not recommended — associated with severe toxicity including violent emesis, hyponatremia, and documented case of brain death.Tran 2025

5. Needle

29–31G, 4–8 mm insulin syringe.

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
