Available from Direct Anti Peptide at ≥98% purity, these capsules represent a convenient, non-invasive research format that eliminates the requirement for injectable administration. Researchers investigating growth hormone axis modulation, metabolic regulation, and related endocrinological pathways frequently select MK-677 capsules as a reliable, precisely dosed laboratory tool. Order now from Direct Anti Peptide and benefit from competitive pricing, rigorous quality control, and dependable fulfillment.

Peptide Structure & Amino Acid Sequence

MK-677 is not a classical peptide but rather a non-peptide small molecule ghrelin mimetic. It belongs to the spiropiperidine class of compounds and functions by selectively binding to the growth hormone secretagogue receptor (GHS-R1a), the same receptor targeted by the endogenous hormone ghrelin. Its molecular formula is C₂₇H₃₆N₄O₅S·CH₄O₃S, with a molecular weight of approximately 624.77 g/mol (mesylate salt form). The CAS number for Ibutamoren Mesylate is 159752-10-0. Unlike peptide-based GH secretagogues, MK-677 demonstrates oral stability and resistance to enzymatic degradation, making it particularly suitable for capsule-format research applications.

Chemical & Physical Characteristics

• Common Name: MK-677 / Ibutamoren Mesylate
• CAS Number: 159752-10-0
• Molecular Formula: C₂₇H₃₆N₄O₅S·CH₄O₃S
• Molecular Weight: ~624.77 g/mol
• Appearance: White to off-white crystalline powder (encapsulated)
• Solubility: Soluble in DMSO and aqueous buffers at physiological pH
• Format: Oral capsules, 10mg active compound per capsule
• Mechanism: Selective GHS-R1a agonist; ghrelin mimetic

In laboratory research, MK-677 is studied for its capacity to elevate both growth hormone (GH) and insulin-like growth factor 1 (IGF-1) without significantly impacting cortisol levels, a characteristic that distinguishes it from many other GH-axis modulators.

Purity & Analytical Verification (HPLC & MS)

Every batch of MK-677 Capsules supplied by Direct Anti Peptide undergoes rigorous analytical testing to confirm identity, purity, and potency. Our active compound is verified at ≥98% purity by High-Performance Liquid Chromatography (HPLC), with mass spectrometric (MS) confirmation of molecular identity. These dual-verification methods ensure that researchers receive a compound of consistent quality suitable for reproducible experimental outcomes. Certificates of Analysis (CoA) reflecting these results are available upon request, providing full transparency for laboratory documentation and regulatory compliance purposes.

Quality Control & Lyophilization Integrity

The active MK-677 raw material used in Direct Anti Peptide capsules is produced under stringent quality control protocols. Prior to encapsulation, the compound is assessed for moisture content, particle size uniformity, and chemical stability. Each capsule delivers a precisely measured 10mg dose of Ibutamoren Mesylate, ensuring consistency across every unit within a batch. Capsule shells are selected for chemical inertness to prevent any interaction with the active compound during storage. Finished capsule batches are subject to uniformity and dissolution testing before release, guaranteeing research-grade reliability from the first capsule to the last.

Safety, Handling & Laboratory Precautions

MK-677 Capsules from Direct Anti Peptide are intended exclusively for use by trained laboratory professionals in controlled research environments. Standard laboratory safety protocols must be observed at all times when handling this compound. Researchers should wear appropriate personal protective equipment (PPE), including gloves and eye protection, and avoid inhalation of any powder residue if capsules are opened for analytical purposes. This compound must be kept out of reach of unauthorized individuals. This product is not approved for human or animal consumption and must not be administered to any living organism.

Reconstitution, Packaging & Storage

MK-677 Capsules are supplied ready for use in research settings without the need for reconstitution. Each unit is individually encapsulated and packaged in a sealed container to protect against moisture, light, and physical damage during transit and storage. Recommended storage conditions are below 25°C in a cool, dry environment, away from direct sunlight and humidity. For extended storage, refrigeration at 2–8°C is advisable. Do not freeze encapsulated product. When stored correctly, MK-677 Capsules maintain stability and potency throughout the stated shelf life indicated on the product label.
