Product Overview

MK-677 (scientifically known as Ibutamoren or Ibutamoren Mesylate) is a potent, non-peptide, orally active ghrelin receptor agonist and growth hormone secretagogue (GHS).

In endocrine and metabolic research models, MK-677 mimics the action of the endogenous hormone ghrelin by targeting and binding to the growth hormone secretagogue receptor (GHSR) located in the brain. This binding action triggers a highly specific chemical cascade: it prompts the pulsatile release of Growth Hormone (GH) from the anterior pituitary gland, which subsequently drives a sustained elevation in circulating Insulin-like Growth Factor 1 (IGF-1) levels in animal test subjects.

Unlike traditional exogenous growth hormones, MK-677 does not cause a sudden, uncoordinated spike in hormone levels. Instead, it amplifies the natural amplitude of physiological GH pulses. Crucially, it achieves this sustained hormone elevation without increasing baseline cortisol (stress hormone) or prolactin levels, making it a key compound for isolating metabolic and tissue-growth pathways.

Key Research Applications

• Anabolic & Body Composition Studies: Investigating the cellular mechanisms behind nitrogen retention, skeletal muscle cell proliferation, and increased fat oxidation (lipolysis).

• Bone Density & Tissue Homeostasis: Evaluating the impact of elevated GH and IGF-1 levels on bone turnover markers, osteoblast activity, and connective tissue synthesis in aging animal profiles.

• Somatopause & Frailty Modeling: Analyzing how oral secretagogues can reverse age-related declines in endogenous growth hormone production without introducing the risks of exogenous GH administration.

Uncompromising Quality Control

Every batch of MK-677 distributed by Onyx Research undergoes independent, third-party analytical testing to guarantee reproducible experimental results.

• High-Performance Liquid Chromatography (HPLC): Confirms an exact purity profile of the Active Pharmaceutical Ingredient (API) exceeding 99%.

• Mass Spectrometry (MS): Verifies precise chemical identity and ensures zero structural contamination.

• Accurate Dosing: Formulated in uniformly measured research capsules for exact, highly reproducible administration in oral-delivery protocols.

Handling & Storage Guidelines

• Form: Solid oral research capsules.

• Storage (Long-Term): Store in a cool, dry place (15∘C to 25∘C) inside the original container. Keep tightly sealed and shielded from direct UV light, moisture, and excessive heat.

• Stability: Chemically stable at room temperature for up to 24 months when stored under optimal laboratory conditions.
