MK-677 (Ibutamoren) – 10mg (60 caps)

MK-677 (Ibutamoren) 10 mg is an oral compound typically supplied in tablet or capsule form, containing 10 mg of ibutamoren per unit. Ibutamoren is classified as a growth hormone secretagogue rather than a SARM. It was developed for investigational research and is not widely approved for general medical use.

Active Ingredient

Ibutamoren (MK-677) is a non-steroidal compound that mimics the action of ghrelin, a hormone involved in growth hormone release. It is designed to stimulate the secretion of growth hormone (GH) and insulin-like growth factor 1 (IGF-1).

Composition

Each tablet or capsule generally contains:

• MK-677 (Ibutamoren) – 10 mg

• Inactive ingredients such as fillers, binders, or capsule materials

Exact excipients vary depending on the manufacturer.

Mechanism of Action

Ibutamoren binds to ghrelin receptors (GHSR-1a), stimulating the pituitary gland to increase growth hormone secretion. Elevated GH levels can subsequently increase circulating IGF-1. Unlike anabolic steroids, it does not directly bind to androgen receptors.

Research and Development Context

MK-677 has been studied in clinical research for potential applications including growth hormone deficiency, muscle wasting conditions, and age-related decline in GH levels. However, it has not received broad regulatory approval for routine therapeutic use.
