Buy MK-677 10MG Pellets Research Chemical Online – USA, Europe & Worldwide

Welcome to RChems EU, a globally trusted supplier of high-purity research chemicals serving academic, pharmaceutical, and biomedical laboratories across five continents. Our MK-677 10MG Pellets offer researchers a standardized, analytically verified tool for exploring growth hormone secretagogue pharmacology and metabolic research.

MK-677, also known as Ibutamoren, is a non-peptide, orally active growth hormone secretagogue (GHS) that functions as a selective agonist of the ghrelin receptor (GHSR-1a). First developed by Amgen in the 1990s and subsequently researched by Merck & Co., MK-677 was originally investigated for the treatment of conditions associated with muscle atrophy, osteoporosis, growth hormone deficiency, and age-related sarcopenia. Unlike peptide-based growth hormone-releasing hormones (GHRH) or growth hormone-releasing peptides (GHRPs), MK-677 acts directly on the ghrelin receptor in the pituitary and hypothalamus to stimulate endogenous growth hormone (GH) pulsatile secretion, leading to elevated serum levels of GH and insulin-like growth factor 1 (IGF-1).

When you buy MK-677 10MG pellets from RChems EU, you receive a rigorously synthesized, analytically verified research compound at ≥99% purity. Each pellet delivers a precise 10mg dose, eliminating weighing variability and minimizing researcher exposure during handling.

Purity & Testing

At RChems EU, we understand that research reproducibility begins with compound integrity. Every batch of 99% pure MK-677 10MG pellets undergoes a comprehensive analytical workflow before release:

1. High-Performance Liquid Chromatography (HPLC-DAD): Quantifies purity against a certified reference standard. Acceptance criterion: ≥99.0% main peak area. All impurities ≥0.05% are reported.
2. Liquid Chromatography-Mass Spectrometry (LC-MS/MS): Confirms molecular ion [M+H]⁺ at m/z 529.3 and characteristic fragmentation pattern. Rules out isobaric contaminants and synthetic byproducts.
3. Nuclear Magnetic Resonance (¹H and ¹³C NMR): Unambiguously confirms structural identity, including the sulfonyl and trifluoroethyl moieties.
4. Karl Fischer Coulometry: Ensures moisture content below 0.5%, critical for long-term pellet stability and preventing hydrolytic degradation.
5. Content Uniformity Testing: Random sampling of pellets from each batch ensures each pellet contains 10mg ± 10% of active ingredient, with relative standard deviation (RSD) <6%.
6. Residual Solvent Analysis (GC-FID): Quantifies residual organic solvents from synthesis per ICH Q3C guidelines.

Only batches that pass all six checkpoints are released for distribution. This rigorous approach means when you buy MK-677 for research from RChems EU, you eliminate batch-to-batch variability—a primary cause of non-reproducible results in growth hormone secretagogue research.

Q3: How discreet is your shipping packaging?
A: Extremely discreet. The outer package is a plain, unmarked box with no branding, no chemical names, and no hazard warnings. The return address is a generic “Fulfillment Department.” Customs declarations list generic terms like “laboratory consumables” or “inert solid reference material.” Inside, pellets are sealed in an opaque, vacuum-sealed mylar pouch with no external labeling. We maintain a 99.7% successful delivery rate to research institutions globally.

Q4: What is the exact purity level, and how is it tested?
A: Minimum 99% pure MK-677 as determined by HPLC-DAD. Each batch’s Certificate of Analysis includes the exact purity percentage (typically 99.2–99.6%), representative chromatograms, LC-MS confirmation, and residual solvent analysis. We use orthogonal analytical methods (HPLC + LC-MS + NMR) to confirm identity and purity. No batch with any single unspecified impurity exceeding 0.2% is ever released.

Q5: How should I store MK-677 10MG pellets after opening?
A: Store in the original sealed mylar pouch or transfer to a tight, amber glass vial with a desiccant packet. Keep at controlled room temperature (15–25°C / 59–77°F), away from direct sunlight, heat, and humidity exceeding 60%. Do not refrigerate or freeze. Under proper storage, chemical stability remains ≥98% for 24 months. Always allow the sealed container to reach room temperature before opening.

Q6: What quantity options are available?
A: MK-677 10MG Pellets are available in four quantities: 50 pellets, 100 pellets, 250 pellets, or 500 pellets. This flexibility allows researchers to order appropriate amounts for pilot studies, full-scale experiments, or long-term research programs. Volume discounts apply to larger quantities.

Q7: Can I receive a Certificate of Analysis before ordering?
A: Absolutely. Contact our scientific support team with the product name (MK-677 10MG Pellets), your institutional affiliation, and intended research application. We will provide a representative CoA from the current production batch, including HPLC purity percentage, impurity profile, and chromatograms. Full, lot-specific CoAs are included inside every shipment.

Q8: What is the mechanism of action of MK-677?
A: MK-677 is a selective, non-peptide agonist of the ghrelin receptor (growth hormone secretagogue receptor, GHSR-1a). It mimics the action of the endogenous hormone ghrelin, binding to GHSR-1a in the pituitary gland and hypothalamus. This binding stimulates the pulsatile release of growth hormone (GH), which in turn increases hepatic production of insulin-like growth factor 1 (IGF-1). Unlike peptide GHSs, MK-677 is orally bioavailable and has a longer half-life.

Q9: What solvents are recommended for dissolving MK-677 pellets?
A: MK-677 is soluble in DMSO (>40 mg/mL) and ethanol (>30 mg/mL). For receptor binding assays, prepare a stock solution in DMSO (e.g., 10–20 mM), then dilute in assay buffer (final DMSO concentration <0.1%). For analytical standards, use methanol or acetonitrile. Aqueous solubility is limited. Avoid prolonged exposure to light and heat after dissolution.

Q10: Are the pellets scored or designed for division?
A: No. The pellets are manufactured as homogeneous, whole-unit analytical standards. They are not scored and are not designed for splitting. Crushing or cutting pellets will compromise dose uniformity. For studies requiring multiple concentration points, dissolve entire pellets in solvent and perform serial volumetric dilutions.

Q11: Can I request a custom dosage or larger quantity?
A: Yes. For research institutions requiring custom dosing formats (e.g., 5mg, 20mg, 50mg pellets) or larger batch quantities (1000+ pellets), contact our institutional sales team. We offer custom synthesis and custom pellet compression with the same ≥99% purity guarantee. Minimum order quantities vary.
