MK-677, also known as a growth hormone secretagogue, is designed to increase the release of growth hormones in the body. If you’re looking to buy MK-677 in Australia, it’s essential to understand how it works. By mimicking the natural stimulating action of ghrelin, the body’s natural growth hormone receptor, MK-677 effectively promotes the release of these vital hormones.


Product Description

With enhanced secretion, users benefit from improved muscle growth, repair, and performance, helping bodybuilders, gym goers, and athletes to get the most out of each pump session. And thanks to its long-acting properties, it can maintain such effects for an extended period of time. It’s because of this that MK-677 has been suggested to be the most effective oral growth hormone secretagogue available to the performance enhancing world.

Key Benefits:

  • Oral administration
  • Long-acting
  • Increases the release of growth hormones
  • Maximises muscle growth
  • Repairs damaged or injured muscle
  • Supercharges pump performance

What is it?

MK-677 (Ibutamoren) is a long-acting, orally-active, and selective agonist of the ghrelin receptor. It is a growth hormone secretagogue which mimics the growth hormone stimulating action of the natural hormone ghrelin. It has amazing muscle building properties and increases the production of natural growth hormone and has effects on appetite, pleasure, mood, biological rhythms, memory, and cognition.

Mechanism of action?

Essentially this compound is able to enhance natural growth hormone secretion in subjects resulting in all the benefits that come with this important hormone including muscle growth, repair and performance capabilities.

Initially developed for use as a treatment for muscle wasting, obesity and osteoporosis it has been demonstrated to increase the release of several other hormones including insulin-like growth factor 1 without affecting cortisol levels and been shown to sustain activation of the GH-IGF-1 Axis and increase lean body mass with no change in total fat mass or visceral fat. This is important because elevated cortisol can lead to immunosuppression and negative correlations with wound healing, memory, and learning.

MK-677 works by increasing the release of growth hormone, amplifying the signalling in somatotropic cells in the pituitary gland, inhibiting the natural release of somatostatin, and inhibiting somatostain receptor signal pathways. All of these activities result in either a net gain in natural growth hormone or an increase in growth hormone potency.

As such this compound has significant potential as a growth hormone supplement and is currently under development as a therapy for building muscle mass and aiding in recovery after surgery.


Ibutamoren has an array of positive effects. It reduces muscle wasting, increases bone density, and surprisingly helps improve the quality and duration of a subjects sleep.

It increases IGF-1 levels which also has a correlation with longevity and as such may have anti-aging properties. Furthermore this compound has been suggested to have a positive impact on mood and is even said to reduce the severity of hangovers!

Product FAQ

MK-677 (ibutamoren) is an agonist of the ghrelin receptor that stimulates GH and IGF-1 production, mimicking the action of ghrelin. By binding to one of the GHSR receptors in the subject’s brain, ibutamoren can effectively raise growth hormone levels while avoiding potential side effects associated with other methods.

Taking MK-677 activates the GHSR in the brain, resulting in increased growth hormone production. This can lead to a higher appetite, improved sleep quality, and even more muscle mass and less body fat. Additionally, it may influence motivation and pleasure, memory, and cognition. Overall, subjects can expect to experience physical benefits from taking MK-677.

MK-677 binds to ghrelin receptors on the surfaces of cells in the body, which then sparks a sequence of reactions leading to an amplified release of GH and IGF-1 hormones. MK-677 has several targets in the body, though most notably, it increases the production and release of growth hormone, leading to improved physical performance.

A clinical trial involving elderly patients found that taking MK-677 daily can significantly increase hormone markers and lean body mass to levels seen in young, healthy adults. It also lowered LDL cholesterol without impacting HDL, with few adverse reactions.

MK-677 can be paired with RAD-140 for an effective combination to help reach fitness goals. One can also combine it with supplements like caffeine and pre-workout drinks to increase energy levels. Overall, stacking MK-677 and other compounds can offer significant benefits. As with all supplements, it is essential to consult a medical professional before taking MK-677.
