MK-677 ibutamoren 10 mg, 60 caps

MK-677 (Ibutamoren) – 10 mg, 60 Capsules

Chemical Name: Ibutamoren Mesylate (MK-677)
Molecular Formula: C₂₇H₃₆N₄O₅S
Compound Class: Growth Hormone Secretagogue / Ghrelin Receptor Agonist

Product Overview

MK-677, also known as Ibutamoren, is a potent oral growth hormone secretagogue that stimulates the body’s natural release of growth hormone (GH) and insulin-like growth factor 1 (IGF-1) by mimicking the action of ghrelin, a hunger-related peptide hormone. Unlike growth hormone injections, MK-677 stimulates endogenous GH release without suppressing other hormonal axes, making it a widely studied non-peptide secretagogue.

Each capsule contains 10 mg of MK-677, with 60 capsules per bottle, offering consistent and controlled dosing for long-term metabolic, recovery, and cognitive function research.

Mechanism of Action

MK-677 acts as a ghrelin receptor (GHS-R1a) agonist, triggering the hypothalamus and pituitary gland to increase natural GH secretion. This results in a sustained rise in GH and IGF-1 levels, which are key drivers of muscle growth, tissue repair, fat metabolism, and cognitive health.

Importantly, MK-677 does not suppress natural testosterone or other hormonal pathways, making it a non-suppressive alternative in research involving anabolic and regenerative outcomes.

Research & Clinical Potential

MK-677 has been involved in multiple clinical trials assessing its effects on:

• Muscle wasting and sarcopenia

• Bone mineral density and osteoporosis

• Sleep quality and REM cycles

• Fat oxidation and metabolic function

• Recovery from injury or surgery

• Cognitive enhancement in aging populations

Research indicates that long-term use increases lean body mass, improves recovery, supports deeper sleep, and may enhance skin, hair, and overall tissue regeneration via GH/IGF-1 pathways.
