It's composed of three amino acids: cysteine, glutamic acid, and glycine
FOXO4-DRI is a D-retro-inverso peptide, meaning its amino acid sequence is reversed and uses mirror-image D-amino acids, making it resistant to enzymatic degradation while maintaining binding activity

Composition Typically formulated as a combined 10 mg vial, commonly: 5 mg CJC-1295 (No DAC) 5 mg Ipamorelin Total = 10 mg blended peptide content Physical form Lyophilised (freeze-dried) sterile powder Stored in sealed laboratory-grade vial Designed for reconstitution in controlled research environments only Research classification This blend is studied in experimental endocrinology and peptide signalling research , focusing on: Growth hormone pulse regulation GHRH and ghrelin receptor pathway interaction Endocrine signalling dynamics Receptor co-activation and feedback mechanisms Hormonal rhythm and secretion pattern modelling Mechanism overview (research context) This combination pairs two different biological pathways: CJC-1295 (No DAC): a modified growth hormone-releasing hormone (GHRH) analog that stimulates pituitary GH release in a short, pulsatile manner Ipamorelin: a selective growth hormone secretagogue that activates the ghrelin receptor (GHS-R1a) to amplify GH pulses Together, they are used in research to model synergistic, dual-pathway GH secretion and study how multiple receptor systems interact Key laboratory interest Researchers commonly use this blend to investigate: Natural-like pulsatile GH signalling patterns Interaction between GHRH and ghrelin systems Endocrine feedback loop behaviour Tissue growth signalling cascades (in vitro / preclinical models) Peptide receptor cross-talk dynamics Stability & handling Lyophilised form improves shelf stability Typically stored frozen before reconstitution (research protocol dependent) After reconstitution, refrigerated conditions are commonly used in lab settings Regulatory status Not approved for human or veterinary use Not a licensed medicinal product Supplied strictly as research chemical / laboratory reagent Intended for qualified research environments only
