Is MK 677 Safe to Take? Look out for These Side Effects

Athletes and gym enthusiasts are often encouraged to regulate their diet and take supplements to aid in building muscle mass and become stronger. The body certainly needs more support when it is being overworked and exercised to such a degree.

This means help to accelerate or supplement the muscle-building process, as well as help to get the right kind of rest so you can go on with your regimen. MK 677 is said to be the supplement you can take to get better results. But what is MK 677 safe to take? The following sections will elaborate further.

What is MK 677 and how does it work?

What is MK 677?

MK 677 is a growth hormone secretagogue (a substance that promotes secretion) that has several benefits for athletes and those working hard at the gym to lose weight and build muscles.

Also known as ibutamoren or Nutrobal, the secretagogue promotes the secretion of HGH (human growth hormone) and IGF-1 (insulin-like growth factor 1) in the human body.

The secretagogue was initially developed to manage the symptoms of disorders that cause muscles to waste, such as osteoporosis, muscular dystrophy and atrophy, to name a few.

But it was soon found that the secretagogue also increases the levels of growth hormones in the body, which can in turn have several beneficial results for athletes and sportspersons, such as fat loss, better sleep quality, and even hair regrowth.

While the following will cover some of the benefits of Ibutamoren, a large chunk of the information will also be dedicated to the possible side effects of the secretagogue. Read on to find out more. 

How does MK 677 help athletes?


As has been mentioned above, MK 677 has several benefits for athletes and those looking to lose fat and build muscles. This is a secretagogue that increases the levels of certain growth hormones in the body, promoting muscle strengthening and growth. The following are some benefits of MK 677:

Fat Loss

Fat loss is one of the most known benefits of MK 677. One of the factors leading to obesity is the stunting in the secretion of the growth hormone. Studies have shown that the use of MK 677 in otherwise healthy obese adults saw an increase in growth hormone levels, fat-free mass and anabolic changes in body composition.

The increase in fat-free mass is also beneficial since you can take MK 677 along with a diet that helps reduce fat, while also building fat-free mass at the same time.

Increased Muscle Mass

Athletes take several supplements to increase their muscle mass, including HGH injections. With MK 677, you can induce the secretion of HGH instead of taking the hormone directly, which may be a safer way of building muscle mass. You do not have to take hormone injections but at the same time, you can increase the levels of the hormone in your body through a steadier process.

Less Recovery Time

MK 677 improves recovery time in athletes and during bodybuilding because it improves the quality of sleep. Studies have shown that prolonged treatment with MK 677 increased REM sleep by 50% in older adults. When you get more REM sleep, the quality of your sleep is automatically improved and your cognitive function is better for more mental and physical activities. Often, people work out twice a day to make use of the reduced recovery time with the MK 677.

What are possible side effects of using Ibutamoren?

Is MK 677 Safe

The following are some of the side effects that you should be aware of before considering taking MK 677. The severity of these side effects may vary in different people, while some people may not experience them at all. Read my MK 677 side effects article if you want a more detailed writeup.


Edema, also known as water retention, is one of the common side effects though it does not necessarily manifest as anything more than a mild symptom. Most of this water, however, is retained in the muscles, which is also one of the ways in which muscle strength gradually increases.

Though, some water may be stored directly under the skin, which may cause visible bloating in some people. Having said that, you can also control the bloating by keeping your dosage level below 25 mg a day.

Increased Appetite 

Increased appetite and hunger is another common side effect, though this tends to appear in the initial stages of your treatment and gradually subsides. This is certainly a potential side effect that could make you lose track of your diet since the secretagogue is likely to make you hungry.

A clever way to manage this side effect without letting it affect your diet is to start taking the MK 677 a few weeks before you begin your diet. This will allow you to cater to your secretagogue-induced hunger pangs without violating your diet. Once your appetite returns to normal, you can begin your diet.

Muscle Pain

In some cases, MK 677 may also cause transient muscle pain. Since the pain is described as transient, it is likely to go away after the initial two weeks from when you start the treatment.

Muscle pain is also expected since the body can take some time to adjust to the new elements it is being introduced to. Your muscles may retain water and gradually build strength, which could initially cause some pain though this is usually a mild side effect that goes away on its own.


A few studies have reported numbness as one of the side effects of MK 677. You may feel numbness in your hands and feet after you take the secretagogue which may feel similar to when you sit on your haunches for too long, or when blood circulation to your hand is reduced.

However, this numbness has no correlation to nerve damage so you should jump to the worst conclusions. This is a common side effect that you may experience even when you inject the growth hormone directly. While it is not certain why this happens, it is a common symptom that also goes away on its own after a few days.

Who benefits the most from taking MK 677

Who Should Take Ibutamoren?

MK 677 promotes the increase of the growth hormone in the body similar to taking HGH, and there is plenty of evidence that it has also been beneficial for older adults. The secretagogue does not alter any other aspect of your body and only impacts it in terms of growth hormones, and the subsequent benefits of increased levels of the hormone.

It is most widely taken by athletes and those looking to lose fat and build muscle mass, but remember that it was developed initially for muscle wasting disorders and continues to be beneficial for the people who suffer from those ailments.
