MK-677 Peptide (10mg Capsules) for Laboratory Research

MK-677, also called ibutamoren, is a synthetic, orally active growth hormone secretagogue that acts as a ghrelin receptor agonist. It is studied in laboratory settings alongside research peptides in work on the GH–IGF-1 axis, feeding-behavior models, and lean-mass signaling, and it is supplied strictly as a research chemical.

Real Peptides supplies MK-677 as 10mg capsules in a 60-count bottle, manufactured in the USA with microcrystalline cellulose as the only excipient. Identity and purity are verified by an independent laboratory, and the certificate of analysis for the current lot is published on the lab results pages so it can be reviewed before purchase. Orders ship from Florida and California facilities within 24 hours. Research use only; not for human or animal consumption.

AboutSpecificationsQuestions

99% Pure | Multi Dose | Finished in the USA

MK-677 (Ibutamoren) capsules deliver a precise 10 mg dose of this potent, orally active ghrelin-mimetic secretagogue in every capsule—no powder weighing, no guesswork. Ideal for labs studying GH-IGF-1 dynamics, feeding-behavior models, and lean-mass signaling, these 60 capsules are manufactured under GMP, HPLC-verified to ≥ 99% purity, and formulated with only microcrystalline cellulose. The ready-to-use, oral format simplifies dosing protocols and ensures each experiment begins with the exact same peptide dose.

What Is MK-677 (Ibutamoren)?

MK-677—also known as Ibutamoren—is a small-molecule ghrelin-receptor agonist that stimulates endogenous growth-hormone (GH) secretion. In preclinical research, MK-677 capsules are used to explore how sustained GH and IGF-1 elevations affect metabolism, muscle signaling, and appetite regulation under controlled, oral-dosing conditions.

Why Choose MK-677 Capsules?

Researchers select MK-677 capsules for their ease of use and translational relevance. The oral-delivery format mirrors human administration routes, while the pre-measured 10 mg amount ensures every study begins with a consistent peptide amount. Whether mapping GH-axis feedback loops or modeling feeding-behavior changes, MK-677 capsules streamline workflows and boost data reproducibility.

What Sets MK-677 Apart?

Unlike injectable secretagogues, MK-677 capsules offer true oral bioavailability, making them ideal for modeling gastrointestinal absorption and long-term dosing studies. Their high purity and minimal-excipient formulation deliver clean, reliable GH-IGF-1 responses, so you can focus on interpreting metabolic outcomes—without extra handling steps or hormone peaks.

Research observations

GH-Axis Activation

Elicits reproducible rises in GH and IGF-1 levels in rodent plasma assays, modeling endocrine pulses.

Appetite-Regulation Models

Modulates feeding-behavior endpoints in diet-induced obesity (DIO) rodent studies.

Lean-Mass Signaling

Enhances protein-synthesis markers (mTOR, S6K) in myoblast and muscle-cell culture assays.

Metabolic-Health Profiling

Impacts adipocyte glucose uptake and lipolysis markers for a full picture of energy balance.

Oral-Dosing Convenience

Capsules ensure uniform 10 mg doses for gavage or dietary-mix protocols—eliminating weighing errors.

Extended Shelf Life

Ambient-stable formulation retains full activity for up to 18 months, easing inventory management.

MK-677 is listed for sale on this page and ships domestically from Real Peptides' Florida and California facilities. Orders placed on business days are dispatched within 24 hours. Purchasers confirm at checkout that they are 21 or older and are acquiring the material for laboratory research use only, not for human or animal consumption.

The listing supplies MK-677 (ibutamoren) as oral capsules containing 10mg each, packaged 60 capsules per bottle. The capsules are finished in the USA under GMP conditions and formulated with microcrystalline cellulose as the only excipient, so no powder weighing or reconstitution is required for handling in the laboratory.

On arrival, the sealed bottle should be kept in a cool, dry place away from direct light, heat, and moisture, and stored in its labeled container. Material should be logged as a research chemical and kept out of reach of children, pets, and anyone not involved in the laboratory work.

Purchasers must confirm they are 21 or older and are buying the material for laboratory research purposes. No institutional affiliation or professional credential is required to place an order. Real Peptides is a chemical supplier, not a compounding pharmacy, and all items are sold strictly for research use.

Useful comparison points include whether a certificate of analysis is published for the specific lot rather than a generic sample, whether testing is performed by an independent laboratory, where the product ships from, how quickly it dispatches, and whether the listing is clearly labeled for research use only.

No. MK-677 is sold here as a research chemical for laboratory use only. It is not a drug, dietary supplement, or cosmetic, is not approved for human or veterinary use, and is not intended for diagnosis, treatment, cure, or prevention of any condition in people or animals.
