05Administration Protocol

Parameter
AOD-9604
Ipamorelin
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. Roll gently. Solution should be clear.
2. Injection site
SQ — abdomen preferred. Rotate sites.
Subcutaneous, abdomen or thigh. Rotate sites. Pinch fat for shallow SQ delivery.
3. Timing
Morning, fasted, ideally pre-cardio for amplified fat oxidation.
Pre-sleep optimal — aligns with natural GH pulse. Some protocols add a morning fasted dose.
4. Storage
Lyophilised: room temp, light-protected. Reconstituted: refrigerate, ≤30 days.
Lyophilised: room temp, protected from light. Reconstituted: refrigerate 2–8 °C, use within 30 days.
5. Needle
29–31G, 4–8 mm insulin syringe.
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
Ipamorelin
+ Tesamorelin
Strong
View Tesamorelin

Ipamorelin (GHRP) + tesamorelin (GHRH analogue) is the textbook dual-axis GH stack. They activate two distinct pituitary receptors — the ghrelin receptor and the GHRH receptor — producing a synergistic GH pulse larger than either alone. Ipamorelin's selectivity (no cortisol/prolactin spike) makes it the ideal GHRP partner for long-term protocols.

Ipamorelin
200–300 mcg SQ · pre-sleep
Tesamorelin
2 mg SQ · same injection · pre-sleep
Primary benefit
Maximal GH pulsatility, fat loss, recovery, sleep depth
+ CJC-1295 (no DAC)
Strong
View CJC-1295 (no DAC)

CJC-1295 (no DAC) is a short-acting GHRH analogue. Combined with ipamorelin (GHRP), the pulse is amplified across both receptor systems with timing similar to native physiology. Without the DAC modification, the stack maintains sharp peaks rather than the sustained elevation seen with CJC-1295-DAC + ipamorelin.

Ipamorelin
200–300 mcg SQ · pre-sleep
CJC-1295 (no DAC)
100 mcg SQ · same injection
Primary benefit
Pulsatile GH stimulation matching physiological pattern
