MK-677, also known as Ibutamoren, or Nutrobal, is a growth hormone secretagogue. Although it’s commonly referred to as a SARM, most of its action centers on stimulating the pituitary hormone to express Human Growth Hormone (HGH).

MK-677 Nutrobal acts by increasing human growth hormone levels and IGF-1 (insulin-like growth factor 1). Nutrabal also mimics the action of ghrelin, a normally occurring hormone responsible for stimulating your appetite.

Research studies and human trials

MK-677 was tested on healthy males over 60 y/o. The result was an increase in muscle mass in strength. Proof of lean body mass strength and increase showed in 40k counting, urinary creatinine excretion, and isokinetic dynamometry.

Nutrobal also shows promise in bone health as it helped improve recovery from a hip fracture. Elderly patients who participated in the study showed improved gait speed, lesser fall incidents, and mean stair climbing.

Research of MK-677 on obese men aged 18-50 manifested increased GH and IGF-1 levels. There was also an increase in energy expenditure, fat-free mass, as well as basal metabolic rate.

MK-677 studies also resulted in improved sleep quality in both young and older adults. Regulated doses administered in two 14-day cycles separated in 14 days showed a 20% increase in REM sleep.

MK-677 Side Effects

There’s a need for further research to determine the safety and efficacy of MK-677, especially when it comes to prolonged use.

If there’s a common side effect associated with MK-677, that would be muscle pain and an almost uncontrollable appetite due to increased levels of ghrelin. Others showed higher fasting blood glucose, indicating lowered insulin sensitivity.

Studies regarding recovery from hip fracture were also cut short because participants were showing unstable blood glucose, increased blood pressure, and risk of congestive heart failure. This indicates that MK-677 is not advised for elderly patients.

MK-677 is also contraindicated for research with cancer patients or patients with a family history of cancer, as well as TH 1 dominants due to its anabolic nature.
