Buy MK677 | Ibutamoren

We are leading UK suppliers of the research chemical MK-677 (Ibutamoren), offering a wide range of the best MK-677 brands and stacks available in the UK. MK-677 is a potent growth hormone secretagogue that stimulates the release of human growth hormone (HGH) and Insulin-like Growth Factor 1 (IGF-1). Although often grouped with SARMs, MK-677 is not a selective androgen receptor modulator but works by mimicking the hormone ghrelin and binding to the ghrelin receptor (GHSR) in the brain to boost GH and IGF-1 production.

Research on MK-677 shows promising effects such as accelerated lean muscle growth, increased strength, reduced body fat, enhanced recovery rates, improved tissue repair and healing, better sleep quality, increased appetite, and overall well-being. MK-677 is non-hormonal and does not suppress natural testosterone levels, meaning no post-cycle therapy (PCT) is required after research use.

Our products are not intended for human consumption, veterinary, or household use.

FREQUENTLY ASKED QUESTIONS

What is MK-677?

MK-677, also known as Ibutamoren, is a research chemical that acts as a growth hormone secretagogue. It stimulates the release of growth hormone (GH) and insulin-like growth factor 1 (IGF-1) by mimicking the hormone ghrelin and binding to its receptors in the brain.

What is MK-677 used for?

MK-677 is studied for its potential to promote increased growth hormone levels, supporting research into muscle growth, fat metabolism, recovery, sleep quality, and metabolic function.

Does MK-677 affect testosterone?

Research shows MK-677 is non-hormonal and does not directly impact testosterone production, unlike steroids or SARMs.

Is PCT needed after MK-677?

Since MK-677 does not suppress natural hormone production in laboratory contexts, post-cycle therapy is generally not required in research protocols.
