Premium MK-677 Ibutamoren Capsules – Laboratory Grade GH Secretagogue
biosynlab delivers pharmaceutical-grade MK-677 Capsules (Ibutamoren) for sophisticated scientific research and analytical applications. As a premier supplier of growth hormone secretagogues to laboratories across the USA, United Kingdom, and European Union, we provide researchers with precisely dosed, high-purity compounds essential for reproducible experimental protocols and cutting-edge endocrine research.
Chemical Composition & Structure
MK-677 (systematic name: (R)-1-(2-methylalanyl-O-(4-hydroxybutyl)-D-seryl)-1-(methylsulfonyl)-1,2-dihydrospiro[indole-3,4′-piperidine] mesylate), commonly known as Ibutamoren or Nutrobal, is a potent, orally active growth hormone secretagogue developed by Merck & Co. Unlike traditional SARMs that target androgen receptors, MK-677 functions as a ghrelin receptor agonist, stimulating the release of growth hormone from the pituitary gland. The molecular formula C₂₇H₃₆N₄O₅S · CH₄O₃S yields a molecular weight of 528.67 g/mol for the mesylate salt.
The compound features a unique spiroindoline core with a piperidine ring, linked to a modified peptide moiety that mimics the action of ghrelin, the “hunger hormone.” This structural design enables oral bioavailability and extended half-life compared to peptide-based growth hormone-releasing hormones (GHRH).
Capsule Advantages for Research
Our 10mg capsules offer distinct advantages for laboratory workflows:
- Precise Dosing: Each capsule contains exactly 10mg of active compound (±2% variance)
- Oral Bioavailability: Capsule form optimized for gastrointestinal absorption studies
- Stability: Encapsulation protects from moisture and oxidation
- Documentation: Batch-coded for complete traceability and chain of custody
- Ease of Use: Simplified administration in research protocols
Research Applications
biosynlab MK-677 Ibutamoren Capsules serve as standardized reference materials for:
- Growth hormone secretion and pulsatility studies
- Ghrelin receptor (GHS-R1a) pharmacology
- IGF-1 axis research and somatomedin studies
- Metabolic research and energy homeostasis
- Appetite regulation and feeding behavior studies
- Bone density and osteoporosis research
- Muscle preservation and protein synthesis studies
- Sleep quality and REM sleep research
- Analytical method development (HPLC, LC-MS/MS)
- Forensic toxicology reference standards
Researchers utilize MK-677 alongside other growth hormone secretagogues including ipamorelin, sermorelin, and GHRP-6, as well as comparative studies with exogenous growth hormone and IGF-1.
