CJC-1295/Ipamorelin

Origin & Classification

The CJC-1295/Ipamorelin kit contains two synthetic peptides. CJC-1295 is a 30-amino-acid analog of growth hormone-releasing hormone (GHRH) modified with a reactive linker (maleimide group) to allow covalent binding to albumin, thereby extending its half-life in circulation. Ipamorelin is a pentapeptide ghrelin receptor agonist engineered to selectively stimulate growth hormone release without significantly affecting ACTH or cortisol. Both peptides are produced by solid-phase synthesis and purified independently before being combined for research.

Mechanism & Research Context

CJC-1295 binds to the GHRH receptor on pituitary somatotrophs, engaging intracellular signaling pathways such as adenylate cyclase activation, cAMP accumulation, and downstream phosphorylation events that culminate in growth hormone secretion. The albumin-binding motif prolongs its presence in systemic circulation, allowing sustained receptor engagement. Ipamorelin interacts with the growth hormone secretagogue receptor (GHSR), a G protein-coupled receptor that stimulates phospholipase C and increases intracellular calcium, leading to additional growth hormone release. When used together, researchers can investigate potential synergistic or additive effects on growth hormone secretion, exploring endocrine feedback loops, receptor desensitization, and cross-talk with metabolic hormones. Studies may assess downstream impacts on insulin-like growth factor signaling, metabolic gene expression, and anabolic pathways while maintaining a strict focus on mechanistic understanding.

Composition & Quality

The kit includes separate lyophilized vials of CJC-1295 and Ipamorelin with purity levels typically above 95 % as established by HPLC and mass spectrometry. Both peptides are synthesized under GMP-aligned conditions, sterilized by filtration, and formulated without preservatives. Quality control involves analysis of molecular mass, peptide content, residual solvents, and endotoxin levels. Storage recommendations include refrigeration of lyophilized material and avoidance of repeated freeze-thaw cycles. Certificates of analysis detail the identity and purity of each peptide and outline recommended reconstitution and handling procedures.
