Ibutamoren MK 677 - Benefits, Results, Side Effects and Dosage 

What Is MK-677 & Is It The Safest SARM?

MK-677, Ibutamoren or Nutrabol is a growth hormone secretagogue that is commonly referred to as a selective androgen receptor modulator also known as a SARM. MK-677 is a muscle-building compound that attaches to receptors in the muscle and bone region. Originally named ‘nutrobal’, MK-677 was created as a hormone booster that was used to help people with insulin and growth hormone deficiencies. This compound provides many benefits with little side effects that I will go into in-depth in this review. Due to the many studies being done on the compound's benefits and side effects it is often considered to be the safest SARM on the market, which makes it one of the best SARMs For Bulking 

How Does MK-677 Work?

MK-677 is a growth hormone secretagogue which works by imitating a hormone called ‘ghrelin’, it functions as a neuropeptide in the central nervous system. The reason why the compound is unique is because it has the ability to stimulate growth hormone levels (GH) and insulin-like growth factor (IGF-1) without suppressing the body’s existing levels of growth hormones and testosterone, which is amazing for bodybuilders as it means you can run a long cycle without the chance of suppression. Also, the compound affects the way you metabolize fat giving the compound fat loss benefits.

MK-677 Benefits

  • Increases Lean Muscle Mass
MK-677 has a fairly high anabolic ratio, which promotes an increase in lean muscle mass. A double-blind trial was conducted on 24 obese men over 8 weeks and they were given MK-677 as a treatment. Within the 8 weeks, the men showed an increase in metabolic rate and had increased in lean muscle mass.
  • Improved Sleep

The compound has been shown to improve the quality of REM (Rapid eye movement) sleep, this is backed by a 1997 study which was tested on eight individuals all of the different ages (men) and the findings suggested that “MK-677 may simultaneously improve sleep quality and correct the relative hyposomatotropism of senescence”. As well as scientific evidence, many users have reported better quality sleep from taking the compound, this is an amazing benefit as high-quality sleep will help athletes recover better from workouts and feel better in general.

  •   Increased Bone Strength 
Studies have shown that MK-677 has a positive effect on bone density, a double-trail was conducted on 24 males, and MK-677 was seen to increase bone density. The compound increases mineral storage through an increased uptake of calcium and iron leading to stronger healthier bones.
  • Prevents Muscle Wasting 
Again studies have shown that MK-677 reverses muscle loss and wasting. This is an amazing benefit of the compound as it can come in very handy for people who are having a break from the gym or recovering from an injury etc. as atrophy is less likely to occur, it is also useful during a cutting phase as even on low calories you won’t experience as much muscle loss.
Other benefits of the compound worth mentioning include increased cognitive performance and prevention of growth hormone deficiency. On top of this, it can be easily stacked with other SARMs such as Ostarine and RAD-140 because of its versatility and is considered to be the safest SARM, due to the many studies being conducted on the compound. 


  • Increased Appetite

MK-677 is notorious for increasing your appetite and is a very common side effect reported by users. This can be good or bad depending on your goal, for example, someone on a bulk who has a small appetite may find it useful for consuming more calories, however, someone in a cutting phase eating in a caloric deficit may see it as a negative effect. To reduce this hunger effect users can run the compound for 5 days then cycle off for two days as the increased appetite comes over time so having a small break will reduce this.

MK 677 Dosage

MK-677 is available in capsule and liquid form and should be taken orally. In terms of dosages, I would recommend 10-25mg MAX from 4-8 weeks, anything over 25mg could give adverse and unwanted side effects. You should slowly increase your dosage especially if you’re new to SARMs and MK-677, for example, start your cycle by taking 10mg a day then finish the cycle taking 20mg. 

MK 677 Half-Life

MK677 has a half-life of 24 hours meaning that it only needs to be taken once a day for optimal results.
