MK677 Peptide: 2026 Research Data, Industry Growth, and Product Comparison Guide

Core Molecular Specs & Technical Index

Abstract MK677 (Ibutamoren) is a growth hormone secretagogue peptide, not a traditional peptide, that stimulates ghrelin receptors to boost IGF-1 and GH levels. This compound is classified as a non-peptide mimetic, meaning it functions through the ghrelin receptor pathway without being a linear amino acid chain. For B2B buyers, understanding the molecular specifications is critical for procurement accuracy. The molecular formula is C27H36N4O5S·HCl, with a molecular weight of approximately 565.13 g/mol. Purity standards for research-grade material typically exceed 98%, with premium suppliers offering 99%+ purity verified by HPLC. Solubility is optimal in DMSO or ethanol, with limited aqueous solubility requiring specific formulation techniques. Storage conditions demand a cool, dry environment at -20°C for long-term stability, with desiccated storage to prevent hydrolysis. The compound exhibits a half-life of approximately 24 hours in biological systems, enabling once-daily dosing in research protocols. Key technical indices include a ghrelin receptor binding affinity (IC50) of 0.3 nM, indicating high potency. The industry standard for endotoxin levels is less than 1 EU/mg, ensuring suitability for in vivo studies. Batch-to-batch consistency is monitored through mass spectrometry and NMR spectroscopy. The compound's stability profile shows minimal degradation over 24 months when stored properly. For bulk procurement, certificates of analysis (COAs) must include these parameters to guarantee quality.

• Purity Standard: Minimum 98% verified by HPLC, with premium grades at 99%+ for research applications.
• Solubility Profile: Soluble in DMSO (50 mg/mL) and ethanol (10 mg/mL), with limited water solubility requiring co-solvents.
• Storage Requirements: Store at -20°C in airtight, light-resistant containers to maintain stability for up to 24 months.
• Endotoxin Levels: Less than 1 EU/mg, meeting rigorous standards for in vivo research protocols.
