NAD+ vs GHRP-2
Side-by-side comparison of key properties, dosing, and research.
- Summary
- NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme found in all living cells that declines dramatically with age. It is critical for energy metabolism, DNA repair, and sirtuin activation. IV and subcutaneous NAD+ supplementation is used in anti-aging protocols and addiction recovery programs.
- GHRP-2 is a potent synthetic hexapeptide that stimulates growth hormone release by activating ghrelin receptors in the pituitary and hypothalamus. It produces one of the strongest GH pulses among GHRPs, though unlike Ipamorelin it does cause modest increases in cortisol and prolactin.
- Half-Life
- Varies by route; IV provides direct cellular delivery
- 15–60 minutes
- Admin Route
- IV, SubQ, Oral
- SubQ, Intranasal
