What is MK-677 (Ibutamoren)?
Orally active ghrelin receptor agonist that stimulates natural GH release and improves deep sleep.
Listed vial contents: 25mg. These are supplied quantities, not administration doses. Current pricing and availability are shown in the strength selector.
What mechanisms are being studied?
MK-677 is a non-peptide, orally active ghrelin receptor (GHS-R1a) agonist that stimulates natural pulsatile growth hormone release from the pituitary. Unlike injected GH, it maintains the body's natural feedback mechanisms. It increases GH amplitude without altering pulse frequency, elevates IGF-1 by 40-97%, and maintains these effects without tachyphylaxis over extended periods. It also significantly enhances deep (Stage IV) sleep quality.
What are the research questions?
- GH deficiency / age-related GH decline: 2-year study in elderly showed sustained IGF-1 increases to youthful levels without significant adverse effects.
- Muscle wasting / sarcopenia: Reversed diet-induced protein catabolism. Increased lean body mass in elderly subjects.
- Sleep quality: 50% increase in Stage IV (deep) sleep and 20% increase in REM sleep.
- Bone density: Increased markers of bone turnover and osteoblast activity in elderly and postmenopausal women over 12+ months.
What does the published work describe?
Nass R et al. (2008) — Sustained 50-70% IGF-1 increases over 2 years in elderly subjects with no significant safety concerns. Copinschi G et al. (1997) — 50% increase in Stage IV deep sleep, 20% increase in REM. Chapman IM et al. (2009) — 2.7 kg lean mass increase over 12 months in healthy elderly.
What are the limits of this evidence?
The research described concerns the cited experimental materials and models, not proof that this supplied vial is a treatment. Cell or animal findings do not establish human benefits. Clinical findings, where cited, apply to the tested formulation and population; they do not validate this research product for human use.

How should I check lot documentation?
Match the product, strength and lot to an original analysis document. Literature describes experimental findings; it does not verify the contents of this inventory. A report is evidence only for the product, strength and lot it names.
How is MK-677 (Ibutamoren) handled in the lab?
For MK-677 (Ibutamoren), record the product code MK677, selected strength and lot before opening. Follow the material-specific safety data sheet and laboratory SOP, with appropriate gloves, eye protection and containment. For a documented dry preparation, let the sealed vial equilibrate before opening to reduce condensation; minimize time open and use clean, compatible vessels.
MK-677 (Ibutamoren) is not a peptide. Select solvent, pH and working conditions from documentation for the specific chemical form and the assay, not a generic peptide reconstitution recipe. Test a small portion, check for precipitation after dilution into assay medium and include vehicle controls.
For MK-677 (Ibutamoren), calculate mass concentration as measured material mass divided by final solution volume. Calculate molarity only with a documented molecular weight for the supplied chemical form; the catalog lists 528.67 g/mol as a reference, not lot confirmation. Where available, use matched-lot net content rather than treating chromatographic purity as a mass correction. Record both stock concentration and subsequent dilution factors.
Use the documented storage conditions for the supplied MK-677 (Ibutamoren) form and lot. For a documented lyophilized preparation, keep the vial sealed and protected from moisture; for solutions, validate temperature, light exposure and holding time in the assay. Use compatible single-use aliquots when appropriate to reduce repeated freeze-thaw. No universal temperature or 28-day solution shelf life is established by the catalog name.
A MK-677 (Ibutamoren) laboratory protocol should record identity, product code MK677, strength, lot, applicable analysis results, solvent and pH, stock concentration, dilution sequence, vessel type, storage history and assay endpoints. Include vehicle and reference controls, independent replicates and predefined acceptance criteria. Separate handling validation from biological interpretation; these notes do not provide administration or dosing instructions.
Research Use Only. Not for human consumption, therapeutic, veterinary or any in-vivo use.

Quality & Verification
MK-677 (Ibutamoren) has a catalog purity specification of ≥99%; this is not a measured result for every vial. Match the product, exact strength, batch and lot to its analysis record and read only the reported fields. HPLC peak-area purity, measured content and endotoxin are separate measurements. A blank field means no result is reported, not zero or passed. A purity percentage alone does not establish identity, sterility or suitability for human use.
