MK-677 Review – Benefits, Mechanism of Action, & Side Effects

Ibutamoren Mesylate, also known under the term MK-677, is a rather controversial supplement that has been developed in recent years. If you research Ibutamoren online, you will quickly discover that we are talking about a supplement that is not so much supported by scientific researchers as you would want it to be. On the other hand, there has been so much talk about Ibutamoren on many forums online, where previous users are sharing their experiences with this supplement, some more positive than others. In today’s post, we will share the details about the mechanism of the act, beneficial effects and potential side-effects, including the suggested dosages for an ultimate effect.

Overview of MK-677

MK-677 is a widely discussed supplement, popular for its abilities to build healthy muscle mass and increase the growth-hormone levels in the body. MK-677 is available over-the-counter, which means that you do not require any doctor's prescription to get a hold of your own bottle of MK-677. However, we do recommend to consult your doctor before you proceed towards using MK-677 just to make sure that no risks are being taken with its use according to your health condition. One negative side of MK-677 is the fact that there are very little scientific researchers that prove the beneficial effects of MK-677. But there are also many user reviews written by men and women all around the world that have spent their lives testing different supplements that will help them achieve ultimate results in their workouts, and there have been far too many positive reviews to lean on to!

How Does it Work?

What MK-677 basically does is increasing the levels of the growth hormone in the body, which helps with the process of muscle mass building. But how does it do that? After you have introduced MK-677 to your body, what it does is start to mimic the action of a hormone called ghrelin in order to bind to one of the ghrelin receptors in the body (GHSR). By doing so, it activates these receptors which increase the secretion of the growth hormone. But that is not all. GHSR also affects different regions that control your appetite, mood, cognitive functions, and your memory, so you can expect all of these regions to be affected by your use of MK-677 as well. One quite positive thing about MK-677 is its ability to increase the levels of the growth-hormone, while at the same time having no effect whatsoever on the levels of cortisol in the brain, which is a hormone guilty for suppressing the immune system and impairing the cognitive functions and memory of the brain – a hormone whose levels have to stay within the normal ranges in order to function well. This is not an ability that many muscle-building supplements have to offer.

The Benefits of MK-677


  • 1. Helps Heal Ligaments, Tendons, Bones
  • By increasing the secretion of the growth hormone in your body, MK-677 works to help the tissues in your body, including your ligaments, tendons and bones, as well as, any present wounds to heal better and in a shorter amount of time. The growth hormone is also able to improve the bone turnover and the bone density so that your bones are healthy and strong.


  • 2. Builds Lean Muscle Mass

  • By being able to increase the levels of the growth hormone and the levels of the insulin-like growth factor 1 (IGF-1), MK-677 is able to build lean muscle mass in no time. But that is not all – you also gain muscle strength and lose more weight than ever, even though, as we will learn in a little while – MK-677 increases your appetite!

  • 3. Increases Oxidation of Fat

  • MK-677 is one of the few supplements that allows you to build great looking, strong muscles while you are actually getting rid of those annoying fats all around your body. By increasing the oxidation of fats in the body, the MK-677 creates a unique opportunity to eliminate the fats and be left with nothing more than lean, vascular looking muscles!



  • 4. Helps To loosen Tight Skin After Weight Loss

  • Obese people suffer the consequences of their poor lifestyle even when they have gotten rid of all those extra body pounds. They have to look at their loosen skin day after day, which continues to cause self-confidence problems even when they have effectively lost lots of weight. MK-677 can help you with that, improving the quality of your skin and nails and tightening your loose skin after weight loss.

  • 5. Increases Appetite

  • One of the great things about MK-677 is its ability to increase your appetite. This means that you are able to intake more calories than ever to allow your muscles to grow and get stronger all of that while you are actually losing weight due to your regular exercise and the oxidation of fat!


    Potential Side-effects

    Unfortunately, there are some mild side-effects that you can expect to come with the use of MK-677. Muscle pain, lethargy, and decreased insulin sensitivity are the most common side-effects, although they do occur only on rare occasions.

    If you are currently pregnant or breastfeeding, please consult your doctor before you proceed towards using MK-677. Currently, there are no scientific reports on the effects of MK-677 on pregnant and breastfeeding women.

    If you are currently taking any medications, please consult your doctor before you proceed towards using MK-677. It is unknown if MK-677 can interfere with other medications and if so, what effects could be expected.

    If you have a history of cancer or you are currently on your treatment for cancer, MK-677 is not recommended for you. It is considered that the increased secretion of the growth hormone and IGF-1 can promote cancer growth.

    Suggested Dosages

    MK-677 comes in the form of capsules for oral use. The safe, recommended dose of MK-677 is 25mg/day. You can take the whole dose at once, or you can also divide the dose to take it once in the morning (12,5mg) and once at night (12,5mg). Sure you will find many users sharing their stories of using much higher doses to achieve quicker results, but we do not recommend you do so.
