MK-677 also known as Ilbutamoren or Nutrobal is one of the most popular compounds on the market right now. MK-677 is a widely discussed supplement which is popular for its abilities to build healthy muscle mass and increase the growth-hormone levels in the body.

How does MK-677 Work?

After you have introduced MK-677 to your body, MK-677 works by imitating the activity of 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. It functions as a neuropeptide in the central nervous system. Mostly, this hormone is known for its ability to stimulate a ravenous appetite! This is in addition to the regulation of energy distribution in the body. It also affects the way our bodies metabolize fat. It can also influence our ability to recover from conditions such as Type 2 diabetes and obesity. 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.

Benefits of MK-677

1 Promote muscle growth

One of the primary benefits you will experience from MK-677 is increased muscle growth. Due to the fact that Nutrobal boosts IGF-1 levels and increases growth hormone production you will be able to put on size much easier.

2 Help in recovery for bones, tendons and ligaments

By increasing the secretion of the growth hormone in your body, MK-677 works to help the tissues in your body, including your bones, tendons and ligaments, 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.

3 Increase oxidation of fat

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 Tighten the skin

Growth hormone and IGF-1 have a positive impact on the skin, hair, and nails. GH has been proven to interact with the skin cells. MK-677 can help you to improve the quality of your skin and nails and tighten your loose skin after weight loss.

5 Enhance sleep quality

We all know that sleep is an important part of the bodybuilding. It allows us to recover quickly and gain strength for the next training session. It has been proven that Nutrobal improves sleep quality.


MK-677 Dosages

MK-677 is mostly available in capsule or liquid form. 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. It's important that you start slow and slowly increase your dosage. So, for example, you can start with a mild dose of 5 mg of Nutrobal and then proceed towards increasing the amount to 8-10 mg in the second week.

Method of Stacking

MK-677 doesn't cause any major-side effects and also possesses unique properties. Therefore, it is stacked with a number of other health supplements to bulk-up and cuttin, in the overall process of gaining health. Nutrobal is therefore stacked with the following compounds:



Based on most researches and what most users have reported, Cardarine is the most stackable compound with Ibutamoren.


Potential Side-effects

The most frequent side effects associated with MK677 include muscle pain, lethargy, and decreased insulin sensitivity. Some studies showed that participants had reduced insulin sensitivity and higher fasting blood glucose. These are the same results shown in people that have higher growth hormone levels.

If you are currently pregnant or breastfeeding, please consult your doctor before you proceed towards using MK-677.

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. Of course, MK-677 is not recommended for cancer patients because it's an anabolic substance that promotes GH and IGF-1 production.


Hopefully, now you know more about MK-677 to use it wisely. MK-677 though marketed as a SARM in reality is a GH secretagogue. While it is a great health benefiting compound, it was originally not meant for such purposes. The timing matters only when you follow the cycle (it has a hal-life of 24 hours). To get the best of this supplement, it is imperative to follow all the dosage and cyclic instructions to amplify long-term bodybuilding goals.
