01Mechanism of Action

Parameter
AOD-9604
BPC-157
Primary target
β3-adrenergic receptor (proposed)Ng 2008
VEGFR2 / nitric oxide / FAK-paxillin axes (proposed)Chang 2014Sikiric 2018
Pathway
β3-AR activation → cAMP → hormone-sensitive lipase activation → triglyceride breakdown to FFA + glycerolNg 2008
Upregulates VEGFR2 → angiogenesis; modulates NO synthase; promotes fibroblast outgrowth via FAK-paxillinChang 2014
Downstream effect
Lipolysis of adipose tissue triglycerides; FFA release for oxidation; minimal IGF-1 / insulin impactHeffernan 2001
Accelerated tissue repair, reduced inflammation, improved gut barrier integritySikiric 2018
Feedback intact?
No GH-axis or IGF-1 feedback
No known endogenous receptor; mechanism still under investigation
Origin
Synthetic modified C-terminal hexadecapeptide fragment of human GH (176-191) with N-terminal Tyr substitutionNg 2008
Synthetic pentadecapeptide derived from a sequence in human gastric juice; first characterised by Sikiric et al.Sikiric 2018

Bacteriostatic water, 1–2 mL
Timing
Morning fasted preferred (pre-cardio)
Aligns with circadian lipolysis.
Local SQ to injury site preferred (anecdotal)
Systemic SQ also used; oral bioavailability shown in animal studies.

05Administration Protocol

Parameter
AOD-9604
BPC-157
1. Reconstitution
Add 1 mL bacteriostatic water to 2 mg vial → 2 mg/mL = 200 mcg per 0.1 mL.
Add 1–2 mL bacteriostatic water to a 5 mg vial. Roll gently; do not shake. Solution should be clear and colourless.
2. Injection site
SQ — abdomen preferred. Rotate sites.
Subcutaneous near the injury site is the most common anecdotal route. Systemic SQ (abdomen) also used. Rotate sites.
3. Timing
Morning, fasted, ideally pre-cardio for amplified fat oxidation.
No strict timing requirement. Most users dose once or twice daily, often morning + evening.
4. Storage
Lyophilised: room temp, light-protected. Reconstituted: refrigerate, ≤30 days.
Lyophilised: room temp, light-protected. Reconstituted: refrigerate 2–8 °C, use within 30 days.
5. Needle
29–31G, 4–8 mm insulin syringe.
27–31G insulin syringe, 4–8 mm. Local injection allows finer 31G.

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
BPC-157
+ TB-500
Strong
View TB-500

BPC-157 and TB-500 (Thymosin β-4) target distinct healing axes: BPC-157 upregulates VEGF-driven angiogenesis and fibroblast migration; TB-500 increases actin remodelling and cell migration via the actin-sequestering β-thymosin domain. Stacked, they cover both vascular (BPC) and structural (TB-500) regeneration pathways. Anecdotally favoured for tendon and ligament repair where both pathways contribute.

BPC-157
250–500 mcg SQ · daily
TB-500
2 mg SQ · 2× per week
Primary benefit
Tendon/ligament/muscle repair via complementary angiogenesis + migration
