MK 677 (Ibutamoren) Review – Nutrobal

MK677 or Ibutamoren or Nutrabol is quite like Cardarine which is wrongly assumed to be a SARM while it is more of a growth hormone secretagogue. In this MK677 Review, you will find more about what Ibutamoren or Nutrobal is, what dosage you should take, what its benefits and side effects are, and much more.

Before I go any further, I must reiterate the fact that MK 677 is not something that has been approved for use by humans. However, it is allowed to be bought and used for research purposes.

MK 677 Review

Let’s delve a bit deeper into this SARM and find out what it really is and what it can do to help you achieve your bodybuilding goals, especially when cutting results are concerned.

What is MK 677?

More often than not, people confuse MK 677 to be a SARM when it is essentially a growth hormone secretagogue or a substance that helps your body produce more HGH on its own.

MK 677 Ibutamoren Review

Thus, it should be clear that MK 677 is going to increase both HGH and IGF-1 (Insulin Growth Factor 1) in your body.

Some of the most important benefits of MK 677 could include:

  • Faster fat burning
  • Increased muscle mass
  • Improvement in skin, hair, and nail health and quality
  • Improved sleep, etc.

Before I described the benefits of MK 677 in detail, let me spell out how it actually works in your body…

How Does MK 677 Work?

As mentioned above, MK 677 helps your body secrete more growth hormone in the most natural way possible. It works by increasing IGF-1 production in your body which acts as a mediator for GH in most cells and tissues.

By increasing HGH production in your body, MK 677 can help your body get similar levels of GH as they were when you were in your teens.

However, at this point, I would like to mention that Ibutamoren is quite weak as compared to HGH shots or injections that people are advised when they suffer from HGH deficiency. The only benefit is that it makes your body produce more of its HGH and there is no synthetic hormone in it.

How Well Researched is Ibutamoren MK 677?

This is another factor that differentiates MK 677 from other SARMs such as LGD 4033, MK 2866, or YK 11 since it is quite well researched. Even though it has not been approved by the FDA for human consumption, it’s getting closer to being approved.

Clinical trials and studies have been reporting great and positive news as far as this compound is concerned.

In other words, it is a well-researched compound and we should expect some good news quite soon.

Is MK 677 Legal?

This brings us to the big question – Is MK 677 legal?

Before you begin using MK 677, you must try to know whether it is legal to buy it or not.

To put things straight, I would mention here that MK 677 is legal to buy and use in most countries around the world except for Australia where you require a doctor’s prescription to buy this compound.

Having said that, it is important to know that is it illegal to use MK 677 in professional sports since it is likely to give the user an unfair advantage over the other competitors.

MK 677 Benefits

Here are some of the most important benefits of MK 677:

Reduces Body Fat

One of the most important as well as the appealing benefits of MK 677 is that it can help cut down your body fat significantly over a period of time.

According to a clinical study, subjects were able to reduce their body fat by as much as 3% in a period of 16 weeks with a daily dose of 15 mg of MK 677.

I must mention here that this reduction in body fat is largely a result of an increase in HGH levels in their bodies since growth hormone tends to speed up fat burning in the body.

Increase Muscle Mass

Yet another important benefit of MK 677 is that it can help increase lean muscle mass in your body, again because HGH promotes fat loss and an increase in muscle mass.

According to a similar study, subjects were able to gain 2lbs of muscle over a 16 week period when they were given 12.5 mg of Ibutamoren on a daily basis. Here, it is important to mention that this increase in their muscle mass was despite any change in their diet or without any exercise.

Thus, it is easy to conclude a MK 677 cycle is a great option to keep the muscle gains intact after you are done with a cycle with bulking SARMs.

Speeds Up Recovery

Normally, a particular muscle group in your body needs at least 72 hours to recover from a training session. What it means is that you can train it again only after 72 hours. MK 677 cuts short this time to just 48 hours allowing you to train it multiple times a week.

What it also means is that your muscle when trained more frequently will grow faster in size and strength.

Improves Sleep Quality

Better sleep is the most well-known benefit of MK 677. Most users say feel that it is an important benefit and they feel more energized, and relaxed since they sleep better when on this SARM.

Since MK 677 helps increase HGH production in your body, it helps you sleep a lot better. In other words, it helps you feel more rested. It is not uncommon for you to feel more rested after 6 hours of sleep than you would normally after 8 hours of sleep. What it also means is that you have more energy throughout the day. Better sleep can also help improve your mood.

In order to get the maximum sleep benefit, it is recommended that you have your dose of MK 677 just about an hour before you hit the bed.

Most users begin feeling the improvement in their sleep quality two weeks into the cycle.

Better Skin and Hair Quality

Apart from improving sleep quality, it can also help increase the growth of your hair and nails. Not just this, it can also improve the condition of your hair and skin.

This is a typical benefit of increased HGH levels in your body. Ibutamoren can not only make your hair grow faster but it can also make them thicker. It’s hardly surprising that a lot of people try this MK 677 for hair growth and to prevent baldness.

It can also help you get younger-looking skin by enhancing your skin elasticity.

MK 677 Dosage and Cycle Length

Most users take a daily dose of MK 677 that’s anywhere between 10-25 mg. I must mention here that the effects may take a while to kick in and this is why it is recommended to continue with an Ibutamoren cycle for an extended period of time.

It is not uncommon for people to continue MK 677 for up to 16 weeks, give a break of 5 weeks in between and then repeat the cycle. Not just this, there are some guys who love this product so much that they keep taking it on and on without a break in between. One of the reasons behind this is that there’s no clinical evidence to suggest side effects of this compound.

Having said that, I would suggest that you do not continue for more than 16 weeks with this product and that you must follow it up with a 5-week break before you begin with it again.

One of the main reasons suggesting this is because most of the studies that have been conducted on this compound have been based on this kind of dosage and cycle only.

Half-Life of Ibutamoren

According to the latest research half-life of this compound is around 24-30 hours. What it means is that it is going to stay in your system for as long as 24 hours. What it also means is that you need to take it once every 24 hours in order to get the best results.

Now, you have two options – you can take your daily dose either in the morning or before bedtime.

  • Taking this daily dose in the morning may help you feel hunger and increase your appetite and this is more suitable for those that want to gain weight or muscle mass. Combining it with an exercise routine and increasing your diet (with MK 677) is a sure way to put on muscle mass.
  • Taking it before bedtime may help you avoid hunger, speed up your metabolism to burn fat and more importantly, improve your sleep quality. So, if your aim is to sleep better then you should have it in the late evening or before you hit the bed.
  • Yet another way to get the most out of MK 677 is by splitting the daily dose into two parts so that you take half of the daily dose in the morning and the rest in the evening. This is the best-suggested routine to get optimal results with Ibutamoren.

Stacking MK 677

It is quite common for bodybuilders to stack MK 677 with anabolic steroids or SARMs. More often than not, bodybuilders use it in order to prevent hair loss while on a steroid cycle as well as to improve their sleep quality. You must keep in mind that a lot of anabolic steroids result in sleep issues and insomnia. In such a case, MK 677 can be a great addition to help them sleep better.

More importantly, you can combine MK 677 with other bulking SARMs in order to keep and maintain muscle gains during SARM cycles. Not just this, it can also be stacked with cutting SARMs such as Andarine S4 or SR9009 for faster cutting results.

MK 677 PCT 

One of the most important features of MK 677 is that it is not suppressive. In other words, it does not suppress testosterone production in your body. Thus, there is no need for a PCT after a MK 677 cycle.

As a matter of fact, most bodybuilders and gymgoers use MK 677 as a PCT drug in order to keep or maintain muscle and strength gains made during a steroid or SARM cycle.

If you plan to take MK 677 as a PCT, then what you should do is that you start it with the SARM cycle from the very beginning and continue taking it for 8 weeks after you are done with the cycle.

Side Effects of MK 677

MK 677 Side Effects

Is MK 677 Safe?

Yep! The best thing about MK 677 is that it does not have any major side effects backed by clinical research and trials.

However, it does not mean that it is absolutely safe and free of side effects. Not much is known about the side effects of SARMs since they still need a whole lot of study to establish their true side effects.

One of the most important things to keep in mind is that a lot of companies selling MK 677 may mix certain adulterants into the product which may reduce the effectiveness of the product and also increase the side effects. Unfortunately, there’s no way to control this since this is a product that has not been approved by the FDA for human consumption and thus its production is not controlled by any agency. In such a case, it becomes important to check user reviews before you buy a product.

Some of the possible side effects (according to anecdotal evidence could include the following):

Water Retention

MK 677 water retention is a common side effect and but is not something very serious. It may not always occur and those that experience it either drink very little water or they are on a high sodium diet.

Thus, the only way out is to drink plenty of water and check your diet for sodium content. This way you should be able to handle avoid water retention within a few days into the cycle.

Increased Appetite

This may be a benefit as well as a side effect. While some users experience hunger pangs a few days into the cycle others do not feel it at all.

If you want to gain weight then it is certainly not a side effect but a benefit for you. In such a case, you must take your daily dose in the morning. And if you want to avoid it, it’s better to have your daily dose of MK 677 before you hit the bed.

I must mention here that this effect also lasts for just a few days and it may wane off a few days into the cycle.

Reduced Insulin Sensitivity

Even though this is not a common side effect, some people do report reduced Insulin sensitivity when on Ibutamoren. It is more likely to occur in people who already suffer from type II diabetes.

One of the most positive things that seem to have come out of research and trials conducted on MK 677 is that it does not change blood glucose levels at all. This goes in favor of MK 677 resulting in the conclusion that it does not reduce insulin sensitivity.

Those that experience reduce insulin sensitivity may do so because of adulterated products. This is why it becomes all the more important to buy a good quality product.

Growing Taller with MK 677

Since MK 677 increases growth hormone production in your body, it is but obvious that a lot of people want to try it to gain height.

Now, it could be effective for increasing height to a certain extent but one of the most crucial factors to take into account is that your growth plates must be open. It is worth noting that your growth plates become completely closed or fused after the age of 25 and it is then it becomes almost impossible to increase your height either with MK 677 or any other growth hormone secretagogue.

Where to Buy MK 677?

While there are a couple of MK 677 brands on the market, you can never be sure of their quality and effectiveness. What I would recommend is that you try a legal and safe alternative that is made with all-natural ingredients and is formulated to mimic the effects of MK 677 without any side effects or PCT.

Does MK 677 really work?

MK 677 or Ibutamoren can be quite effective in preventing muscle loss. It not only helps speed up fat burning in your body but also increases lean muscle mass. Yet another known benefit is that it can help boost HGH production in your body which can help improve your overall health in many ways.

Can MK 677 make you taller?

Yes, it can certainly make you taller but this effect is visible only in people whose growth plates have not fused. Generally, growth plates in your body get fused by the time you are 25. Thus, people above this age are not going to get any taller with MK 677.

Does MK 677 make you sleepy?

One of the important benefits of MK 677 is that it can help improve your sleep quality. Thus, it can make you feel more rested after just 6 hours of sleep as compared to how rested you normally feel after 8 hours of sleep.



Ibutamoren MK 677 is one of the HGH precursors that is assumed to be a SARM. However, it can be exceptionally food for increasing muscle and reducing excess body fat. Even though it is supposed to be relatively safer, a lot more study is needed to establish its side effects. In such a case, it is always best to opt for natural alternatives such as Ibulatalean from Brutal Force so that you can get all the benefits while doing away with the negatives.
