01Mechanism of Action

Parameter
Adamax
Hexarelin
Primary target
Melanocortin receptors (MC-Rs) in hippocampus and cortex
Ghrelin receptor (GHS-R1a) + cardiac CD36Smith 1996Ghigo 1997
Pathway
ACTH(4-10) fragment → MC-R binding → BDNF/trkB upregulation → neurotrophic signaling
GHS-R1a → Gαq → Ca²⁺ → GH release. CD36 engagement → direct cardio-tropic actionGhigo 1997
Downstream effect
Increased hippocampal BDNF expression, trkB tyrosine phosphorylation, enhanced conditioned avoidance learning, circadian rhythm normalizationDolotov 2006Arushanian 2008
Strong GH pulse + IGF-1 elevation; cardio-protective effects in animal MI modelsGhigo 1997

04Side Effects & Safety

Parameter
Adamax
Hexarelin
Cardiovascular effects
ACTH(4-10) fragments may have pressor and cardioaccelerator actions at high dosesGruber 1984
Effects attenuated by α/β-receptor antagonists; observed at 30–1000 nmol/kg IV in rats.
Natriuretic effect
ACTH(4-10) exhibited natriuretic activity at lower doses (7 nmol/kg)Gruber 1984
Behavioral suppression
Suppression of aggression, reduced orientation-cognition reactions in rabbitsTeter 2001
May reflect anxiolytic or stress-dampening profile.
Long-term safety
Unknown — chronic human safety data lacking
Cortisol elevation
Modest at high dosesGhigo 1997
Prolactin elevation
Modest at high dosesGhigo 1997
Hunger
Strong appetite increase via ghrelin agonism
Tachyphylaxis
Receptor desensitisation with chronic dosingGhigo 1997
Cardiac effects
Direct cardio-tropic; potential benefit in MI but unstudied in humansGhigo 1997
IGF-1 elevation
Strong; monitor with chronic high-dose use
Cancer risk
Contraindicated in active malignancy (GH/IGF-1 axis)
Pregnancy / OB
Avoid
Absolute Contraindications
Adamax
  • ·Pregnancy and lactation (precautionary; no data)
  • ·Active cardiovascular instability (due to potential pressor effects)
Hexarelin
  • ·Active malignancy
  • ·Pregnancy / breastfeeding
  • ·Disrupted hypothalamic-pituitary axis
Relative Contraindications
Adamax
  • ·Hypertension (monitor BP if using higher doses)
  • ·Renal impairment (natriuretic effects may alter electrolyte balance)
Hexarelin
  • ·Untreated diabetes
  • ·Severe hyperprolactinemia

05Administration Protocol

Parameter
Adamax
Hexarelin
1. Reconstitution (if lyophilised)
Add sterile water or bacteriostatic water to lyophilised vial per manufacturer guidance. Roll gently — do not shake. Ensure clarity before use.
Add 2 mL bacteriostatic water to 5 mg vial → 2.5 mg/mL = 250 mcg per 0.1 mL.
2. Route
Intranasal administration is the primary route in animal and exploratory human studies. Delivered via nasal spray or dropper to ensure mucosal absorption.Dolotov 2006Smolnik 2000
SQ — abdomen or thigh. Rotate sites.
3. Timing
Variable. Single-dose protocols for acute cognitive tasks; chronic daily dosing for circadian rhythm normalization and sustained neuroprotection.
Pre-sleep + fasted preferred. Cycle on/off to avoid tachyphylaxis.
4. Storage
Lyophilised: room temperature, light-protected. Reconstituted: refrigerate 2–8 °C, use within manufacturer-specified timeframe.
Lyophilised: room temp, light-protected. Reconstituted: refrigerate ≤30 days.
5. Needle
29–31G, 4–8 mm insulin syringe.

06Stack Synergy

Adamax
+ Semax
Moderate
View Semax

Both Adamax and Semax are ACTH(4-10)-derived nootropics acting via melanocortin receptors and BDNF upregulation. Adamax has distinct amino acid modifications at positions 8-10, potentially offering complementary receptor binding profiles or metabolic stability. Stacking may amplify neurotrophic signaling and cognitive enhancement, though direct synergy studies are absent. Theoretical multi-pathway benefit.

300–600 mcg intranasal
Frequency
Once daily, morning or pre-cognitive task
Primary benefit

Hexarelin
+ CJC-1295 (no DAC)
Strong
View CJC-1295 (no DAC)

Hexarelin (GHRP) + CJC-1295-no-DAC (GHRH analogue) is the higher-amplitude variant of the standard GHRH+GHRP stack. Hexarelin produces a stronger pulse than ipamorelin but with cortisol + prolactin signal — choose this stack for maximum GH amplitude when side-effect tolerance is acceptable. Cycle aggressively.
