01Mechanism of Action

Parameter
Hexarelin
Pinealon
Primary target
Ghrelin receptor (GHS-R1a) + cardiac CD36Smith 1996Ghigo 1997
Antioxidant defense + neuronal gene expression (proposed)Khavinson 2014
Pathway
GHS-R1a → Gαq → Ca²⁺ → GH release. CD36 engagement → direct cardio-tropic actionGhigo 1997
Modulation of antioxidant enzymes (SOD, catalase) + neurotrophic factor expressionKhavinson 2014
Downstream effect
Strong GH pulse + IGF-1 elevation; cardio-protective effects in animal MI modelsGhigo 1997
Reduced oxidative stress in neurons; improved cognitive function in age-related declineKhavinson 2014

05Administration Protocol

Parameter
Hexarelin
Pinealon
1. Reconstitution
Add 2 mL bacteriostatic water to 5 mg vial → 2.5 mg/mL = 250 mcg per 0.1 mL.
Add 1–2 mL bacteriostatic water to 10 mg vial.
2. Injection site
SQ — abdomen or thigh. Rotate sites.
SQ — abdomen preferred.
3. Timing
Pre-sleep + fasted preferred. Cycle on/off to avoid tachyphylaxis.
Daily during cycle, any time.
4. Storage
Lyophilised: room temp, light-protected. Reconstituted: refrigerate ≤30 days.

06Stack Synergy

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.

Hexarelin
100 mcg SQ · pre-sleep
CJC-1295 (no DAC)
100 mcg SQ · same injection
Primary benefit
Maximum GH pulse amplitude (with side-effect signal)
Pinealon
+ Epitalon
Moderate
View Epitalon

Pinealon (neuroprotection) + Epitalon (telomerase activation) form the canonical Khavinson "longevity stack" — both pineal-derived bioregulators with complementary axes. Pinealon supports neuronal antioxidant defense; Epitalon supports telomere maintenance. Anecdotally cycled together 1–2× per year.

Pinealon
5–10 mg SQ · daily × 10 days
Epitalon
5–10 mg SQ · daily × 10 days (overlap or alternate)
Primary benefit
Neuroprotection + telomere preservation
