What is MK-677?

Ibutamoren, most known by the name MK-677, is a powerful performance-enhancing medicine, which can change the bodybuilding dynamics in human beings. Iit is common for many to regard it as a SARM (Selective Androgen Receptor Modulators). Ibutamoren (MK-677) is undoubtedly the most popular and widely used rapid muscle-building product in the market. It offers enormous training benefits. That is primarily why almost all heavyweight athletes, bodybuilders & weightlifters recommend it.


Growth hormones are a necessity throughout our lifetime. A human being’s growth can be of two main types, the first being tallness, in which humans grow from birth to a certain age, and this is maintained by the insulin-like growth factor-1 or IGF-1. The second type of growth happens during the gestation period, which is governed by IGF-2. Therefore, it is crystal clear whatever growth happens in a child before they are born is through IGF-2. 

Ibutamoren is something that mimics the effect of IGF-1 in the body. Specifically, it increases the body’s production of Insulin-like Growth Factor 1 and Growth Hormone. The level of Growth hormone in the body, increases to levels that can be compared to levels that are found in adolescents.

This compound can be taken by teenagers too. However, it may lead to a minute growth spurt if they are still in the developing stage of their life. This drug makes the body manufacture more growth hormones. But in the case of Growth hormone therapy, the hormone gets injected into the body.


There are multiple benefits of MK-677. The following are some of its benefits proven through clinical trials conducted on the drug.

Oral Bioavailability

The most important benefit of Ibutamoren is it has a very high Oral bioavailability. This drug can be taken orally by mixing in water and it does not need to be injected like in the case of growth hormone therapy. The working of it is similar to growth Hormone release peptide but it has a higher bioavailability than it. This drug also has a half-life of 24 hours, which means you can just take it once a day instead of multiple times and enjoy its benefits.

Helps Build Muscles

Helps Builds Muscles

Mk-677 has been used to build lean muscle mass often. As explained earlier, it leads to an increase in Growth hormone and IGF-1 in the body. It stimulates an increase in muscle size and strength in the human body. MK-677 is used by many athletes and bodybuilders for this very reason, as it leads to increased hormone production. When it comes to MK-677, its results of muscle growth will vary from person to person depending on their exercise regime and total health conditions.

Safer and Better Than Growth Hormone Therapy

The third benefit is that it is safer than growth Hormone therapies (GHT) which some people prefer over drugs. It is considered safer as it does not take the level of hormones to a dangerously high level which happens in cases of GHT. This unnatural increase in hormone levels leads to illnesses like cancer.

 What MK-677 does is makes the body itself produce higher levels of Growth hormones and IGF-1 without making it go to unnaturally high levels which is harmful to the body. 

Combats Aging

Growth Hormone naturally begins to deteriorate once a certain age is hit, as seen with other hormones too. Aging individuals can benefit from taking MK 677. Growth Hormone and IGF-1 will be increased in the body with its consumption and that would be helpful for people who are aging. Aging individuals taking MK 677 can improve their hormone profiles overall as it gives their declining Growth Hormone levels a boost.  

There was a study conducted with 65 elderly men and women. They were given MK-677 daily. It was then observed that the IGF-1 and GH levels in their boy increased to those of healthy young adults without any serious adverse effects. There was another study conducted with 24 obese males, where it was observed that it rejuvenated the Growth Hormone profile. 

Benefits With Digestion

The primary reason that athletes, sportsmen, and bodybuilders prefer taking MK-677 compared to other drugs is they offer similar benefits just like some growth hormone therapies that are conducted. There was a study conducted for 2 months, where the test subjects were obese. It was found in the study that MK-677 increases growth hormone secretion in the body. It increased lean muscles and energy expenditure in the subjects too. The subjects that were given MK-677 had got on 3kg more lean muscle than the ones who received a placebo. This particular trial was 14 days long. The subjects who were on a diet kept on the lean muscle mass in their body as available in their body initially.

Better Sleep

It was established that MK-677 improves sleep as well. There was a study conducted where it was noticed that the test subjects who had taken MK-677 slept 20% better than the others. Also, there was a 20% increase in REM i.e., Rapid Eye Movement sleep.


There are no particular dosages instructed for Mk-677. The clinical trials which were conducted prescribed their subjects 25 mg. So, a 25 mg dosage goes for most people. 

because 24 hours is the half-life of the drug, the pill can be taken once daily at any time of the day. It does not need to be taken multiple times for the effects to last. But it is advised that the pill needs to be taken at the same time daily. If you want to be taking it at 8 AM or night at 6 PM, you should do it daily for as long as you plan on taking the drug. The best time should be in the morning post waking up. Taking it regularly can show some positive effects on the body.

MK-677 has many benefits as we have explained in the previous sections. If you want to use Ibutamoren, the suggestion from our end would be to use the 60-capsule-containing bottle by iMuscle.
