MK-677, known as Ibutamoren or Nutrobal, is a non-peptide growth hormone secretagogue. It is often classified as a selective agonist of the ghrelin receptor, a hormone receptor involved in regulating appetite, growth hormone secretion, and energy metabolism.

At Loti Labs, we pride ourselves on stocking high-quality research chemicals. Buy MK-677 for sale only for research purposes and not for human consumption. It is available in liquid form at 25 mg per ml.

WHAT IS MK-677 (IBUTAMOREN)

MK-677 is a non-peptide spiro piperidine previously shown to be functionally and mechanically indistinguishable in vitro and in vivo from the potent peptide GHS GHRP-6. MK-677 elevates GH levels, as well as IGF-I and cortisol levels, in dogs after oral administration.

MK-677 is used primarily as a potential treatment for conditions characterized by muscle wasting and impaired growth hormone levels, such as age-related muscle loss or certain hormone deficiencies. 

STRUCTURE OF MK-677 (IBUTAMOREN)

Molecular Formula: C₂₇H₃₆N₄O₅S

Molecular weight: 528.7 g/mol

CAS number: 159634-47-6

IUPAC name: 2-amino-2-methyl-N-[(2R)-1-(1-methylsulfonylspiro[2H-indole-3,4′-piperidine]-1′-yl)-1-oxo-3-phenylmethoxypropan-2-yl]propanamide

MECHANISM OF ACTION

MK-677 (Ibutamoren) stimulates the release of growth hormone and insulin-like growth factor 1 (IGF-1) in the body. These hormones promote muscle growth, enhance recovery, and regulate several metabolic processes.

MK-677 (Ibutamoren) is active after oral administration in animals with a half-life of more than twenty (20) hours (almost 24 hours).

MK-677 (IBUTAMOREN) EFFECTS

Based on available research, the benefits of MK-677 (Ibutamoren) include:

• Increases growth hormone levels
• Strengthening muscle mass, preventing muscle loss
• Fat burning
• It strengthens bones and enhances bone density
• Reverses nitrogen waste
• It enhances sleep

MK-677 (IBUTAMOREN) SIDE EFFECTS

Below are what researchers noticed during clinical trials with MK-677 (Ibutamoren) use in animal test studies.

• water retention and swelling
• reduced insulin sensitivity and increased hunger
• joint and muscle pain
• headaches and migraines
• increased anxiety
• lethargy
