Buy MK-677 Powder (Istobal/Nutrobal)

Product Overview

MK-677 Powder, alternatively designated Ibutamoren, Istobal, or Nutrobal, comprises a superior brandless research chemical at ≥98% purity, crafted exclusively for rigorous laboratory pursuits in analytical chemistry and receptor pharmacology. This high-purity formulation acts as a steadfast reference standard, enabling trained researchers to scrutinize molecular architectures, dissolution kinetics, and binding specificities under meticulously governed in vitro conditions. Its fine particulate nature and lot-specific documentation render it indispensable for consistent, non-clinical investigative workflows across institutional platforms.

Chemical Identity & Classification

MK-677 registers under CAS number 159752-10-0 (mesylate salt), anchoring its profile within authoritative chemical compendia for unequivocal traceability. The molecular formula C28H40N4O8S2 yields a molecular weight of 624.77 g/mol, arming investigators with exact coordinates for spectrometric targeting and quantitative calibrations. Designated synonyms—Ibutamoren mesylate, MK-0677, Crescendo—place it as a non-peptidic synthetic analytical reagent and reference entity within growth hormone secretagogue receptor (GHSR) study domains. Such taxonomy confines it to in vitro analytical deployment by certified laboratory cohorts.

Chemical & Physical Characteristics

MK-677 Powder manifests as a white to beige crystalline solid, exhibiting favorable flow dynamics for sub-milligram precision in laboratory apportionment. Solubility attains ≥50 mg/mL in aqueous media and DMSO, with supplementary compatibility in ethanol and PEG formulations, delineating solvent hierarchies for reconstitution and partitioning experiments. Metrics encompass melting point 164-170°C, boiling point ~869°C (predicted), density ~1.4 g/cm³, LogP 4.97 signaling lipophilicity, and hygroscopic propensity necessitating desiccated regimes, complemented by chiral stereocenter at C17. These observables underpin reproducible HPLC resolutions, LC-MS adduct formations (m/z 625 [M+H]+), and NMR delineations (complexity index 1010), furnishing empirical benchmarks sans applicative inferences.

Purity & Analytical Verification

MK-677 Powder lots uniformly exceed ≥98% purity, ratified by HPLC peak purities, LC-MS isotopic distributions, 1H/13C-NMR conformance, and CHNS elemental assays mirroring C28H40N4O8S2 stoichiometry. Rigorous limits circumscribe heavy metals (<5 ppm), residuals per ICH Q3C, microbial sterility, and endotoxin quanta (<0.5 EU/mg), consummating reference archetype. Per-lot Certificates of Analysis (COAs) articulate assay quantitations (>99% archetypes), spectral tracings, optical rotations, and moisture profiles (<1.0% KF), tendered for QA assimilation. This panoply validates steadfastness for potency ladders and adulterant trajectories.

Quality Control & Batch Integrity

Batch orchestration imprints singular lot codexes traversing from API crystallization to cryogenic lyophilization, enshrining custodial continuity. Iterative surveillances adjudicate polymorphicity (XRPD), particle sizing (D50 ~5-15 μm), and enantiomeric fidelity (>99.5% S-configuration), buttressed by GLP externals for oxidative/RH stressors. Photostability and thermal excursions (ICH Q1B/Q1A) certify 36-month dispatch at 2-8°C, archiving retainers for forensic re-interrogation. Archival GMP annals—campaign yields (85-92%), bioreactor parameters, and aberration root-causes—underpin inspectorate scrutiny, while SPC confines CVs <0.5% for inter-lot superimposability in longitudinal arrays. This bastion obviates stochasticity.

Safety, Handling & Laboratory Precautions

Commissioned technicians interface MK-677 Powder amid isolator-grade enclosures, clad in halcyon PPE taxonomies: Viton gauntlets, P100 cartridges, encapsulating hoods, and grounded footwear forestalling static ignition. Antisolvent funnels and gloveport isolators preempt particulates; excursions trigger nano-filtrate sorption and alkaline quenching congruent SDS canons. GHS07 imputations (H315/H319/H335, aquatic acute H402) prescribe deluge fixtures, 20-minute ablations, and fugitive cabinets. Effluvia cascade through plasma torches with RFID pedigrees, embargoing lay ingress via biometrics. Demarcations territorialize peril.

Packaging, Labeling & Storage

MK-677 Powder vends in photoperiodic Schott vials or fluoropolymer drums with septum crimp-seals and zeolite sentinels repulsing hydrolytic forays. Effigies intone CAS 159752-10-0, C28H40N4O8S2, ≥98% fiat, RFID-lots, IMDG 9 labels, and tessellated pictograms per UN RTG. Inter at 2-8°C (short-term) or -20°C (protracted) amid argon, fractionating to avert sublimation, hygroscopy <40% RH paramount. Partitioned cryostats forefend admixtures.

Intended Research Use & Market Positioning

MK-677 Powder girds analytical crucibles, GHSR pharmacophores in discovery suites, endocrinologic forensics, and academe ghrelin mimetic deconstructions via granulometric exactitude. It catalyzes pulsatile GH/IGF-1 secretagogue assays (EC50 ~1.4 nM GHSR), catabolic buffers, and orexigenic titrations in U2OS transfectants—vitro circumscribed. Emulating “Next LVL Muscle” echelon sans provenance premiums, ≥98% matrix economizes terascale sieves. Keystone for mimetic hierarchies, pulsatility emulations, and secretagogue consortia in sanctioned ambits.

Ordering, Availability & Fulfillment

MK-677 Powder accrues in bulwarked depots traversing WooCommerce bastilles with post-quantum ciphers enfranchising tender spectra. Thermoacoustic shrouds expedite via stratocruisers, blockchain ledgers etching 24-72h domestics/5-10 globals. Graduated tariffs, OAuth COAs, and MRP orbits attune lab metabolisms; polyglot sentinels dissect lex loci. Conduits catalyze epiphanies.
