- Before diving deeper into refrigeration requirements, understanding the structural and functional differences between these two peptides clarifies why both require identical storage protocols despite different mechanisms.
- CJC-1295 no DAC (Mod GRF 1-29)
- 29 amino acids
- GHRH receptor agonist; stimulates pulsatile growth hormone release from pituitary somatotrophs
- ~30 minutes (biological); peptide bond stability ~7-14 days at 4°C
- Oxidation of methionine residues; hydrolysis of peptide bonds at pH extremes
- Longer sequence means more sites for degradation—temperature control critical
- Ipamorelin
- 5 amino acids
- Ghrelin receptor agonist; selective GH release without cortisol or prolactin elevation
- ~2 hours (biological); peptide bond stability ~14-21 days at 4°C
- Peptide bond hydrolysis; less vulnerable than CJC due to shorter sequence
- Shorter sequence tolerates storage slightly better, but refrigeration still mandatory
- Combination (CJC + Ipa)
- Both compounds in one vial
- Synergistic GH release—CJC amplifies pulsatility, Ipamorelin triggers secretion
- Variable; use shortest half-life for protocol timing
- Degradation of either component compromises research outcomes
- Store combined solutions identically to individual peptides—2-8°C, 28-day max
- Both peptides contain amide bonds linking amino acids. These bonds are susceptible to hydrolysis (cleavage by water molecules) at non-neutral pH and elevated temperatures. Refrigeration slows hydrolysis rates by reducing kinetic energy. The combination products available through suppliers like Real Peptides contain both peptides in a single vial, which simplifies reconstitution but doesn't change storage requirements—both components need identical refrigeration.
