Ipamorelin is a highly selective growth hormone secretagogue that stimulates GH release without significantly affecting other hormones such as cortisol or prolactin. Its favourable selectivity profile makes it one of the most studied peptides in GH research.
Ipamorelin is a synthetic pentapeptide (5 amino acids) that acts as a selective growth hormone secretagogue. It stimulates the pituitary gland to release GH by activating the ghrelin/GHS receptor. ORYN Ipamorelin is formulated at >99% purity with 6 mg in a precision pen system.
Ipamorelin binds to the GHS-R on pituitary cells, triggering calcium-dependent GH release. Unlike other GH secretagogues, it is highly selective — it does not significantly stimulate ACTH, cortisol, or prolactin.
Researched for GH stimulation, body composition, bone density, sleep architecture, post-operative recovery, and age-related GH decline. Its selectivity is particularly valuable in studies requiring isolated GH elevation.
Via a pre-mixed pen containing 6 mg in 3 mL. Designed for subcutaneous injection, typically timed for the evening or pre-sleep to complement natural GH secretion patterns.
Produced to >99% purity in GMP-certified facilities with ISO 7 cleanroom standards. Third-party HPLC and mass spectrometry validate every batch. Certificates of Analysis available on request.
Store at 2-8°C, protected from light. Do not freeze. Shelf life is 24 months when stored correctly.
Most commonly studied alongside CJC-1295. This combination targets two different GH-stimulating pathways for synergistic GH release. For research purposes only.
Each ORYN Ipamorelin pen is calibrated for a 30-day dosing period. The 6 mg / 3 mL formulation delivers precise daily doses throughout the full monthly research cycle.
Ipamorelin's defining characteristic is its selectivity — it produces a cleaner GH release without elevating cortisol, prolactin, or significantly stimulating appetite, unlike GHRP-6.
