MK-677 (also known as ibutamoren), promotes the secretion of the growth hormone (GH) and increases insulin-like growth factor 1 (IGF-1). Ibutamoren increases growth hormone levels by mimicking the action of the hormone ghrelin and binding to one of the ghrelin receptors (GHSR) in the brain.

A common misconception is that MK-677 is a SARM, MK-677 isn't actually a SARM but is rather a Growth Hormone Secretagogue.

MK-677 is not an anabolic steroid and is not a SARM either. MK-677 isn’t listed in any category of scheduled substances in the UK, this means it is completely legal to buy and sell in the UK. However, this also means that it cannot explicitly be sold as a food or nutritional supplement so is therefore only to be sold for research purposes

The benefits of MK-677 can include muscle-building, a reduction in muscle wasting, better bone density, improved sleep, and anti-aging properties. It may also have nootropic effects and it can be beneficial in treating growth hormone deficiencies.

MK-677 WILL NOT suppress your natural testosterone so therefore no PCT is required.

You can stay on MK-677 all year around if you wish as it will not suppress your testosterone. Many of us here at MK677 Direct use MK-677 year round with no problems. However, many users also opt to cycle the product for 12-16 weeks. Although this isn't neccesary, it all comes down to personal preference.
