Mechanism of Action
Ipamorelin binds to ghrelin/GHS receptors on pituitary somatotroph cells, triggering selective growth hormone release. Unlike broader GH secretagogues, it does not stimulate cortisol or prolactin secretion, resulting in a cleaner GH response profile in research models.
Storage & Handling
Store lyophilized at -20°C or 2-8°C. Reconstituted: 2-8°C, use within 30 days.

FAQ
Frequently Asked Questions
What makes ipamorelin different from other GH secretagogues?
Ipamorelin is highly selective for growth hormone release. Unlike GHRP-6 or GHRP-2, it does not significantly increase cortisol, prolactin, or appetite-stimulating hormones, making it ideal for isolated GH research.
Can ipamorelin be combined with CJC-1295?
Yes. Ipamorelin (ghrelin receptor) and CJC-1295 (GHRH receptor) target complementary pathways and are frequently studied together for synergistic GH release effects.
How should ipamorelin be stored?
Store lyophilized ipamorelin at -20°C for long-term or 2-8°C for short-term storage. Reconstituted peptide should be refrigerated at 2-8°C and used within 30 days.
