Growth Hormone
Ipamorelin
Ipamorelin (selective GHS-R1a agonist)
Ipamorelin is a synthetic pentapeptide agonist at the growth hormone secretagogue receptor (GHS-R1a). Its defining research characteristic is selectivity: unlike earlier secretagogues such as GHRP-6 and GHRP-2, it shows minimal effect on ACTH, cortisol, and prolactin at comparable doses in animal models. That clean profile is precisely why it remains a useful tool compound for isolating GH-axis effects.
Research applications
- GHS-R1a receptor selectivity and binding studies
- Pituitary somatotroph response assays
- Comparative secretagogue selectivity profiling
- Pulsatile secretion pattern research
Storage
Store lyophilized powder at -20°C protected from light. Reconstituted solution stable at 2-8°C for up to 30 days.
Reconstitution
Reconstitute with bacteriostatic water directed down the vial wall. Swirl gently.
