Ibutamoren(MK677): Medical Benefits & Risks

Ibutamoren, also known as Nutrobal or MK 677, is a potent HGH (Human Growth Hormone) secretagogue that boosts HGH levels in the body.

It was first developed to treat muscle wasting diseases like osteoporosis. When clinical trials began, researchers discovered that it significantly increases IGF-1 and HGH levels in humans.

Increased HGH and IGF-1 levels, as you may know, provide a slew of advantages in athletic performance.

We’ll go over everything you need to know about MK 677 in this article, including its benefits, side effects, and dosages.

What are the Benefits of Ibutamoren?

MK 677 is used by athletes and bodybuilders for a variety of reasons.

Some of the most notable advantages of including Ibutamoren in your performance-enhancing stack are as follows:

Reduced Muscle Catabolism

Nutrobal has been shown to reduce muscle loss during a cutting cycle. Participants in this study were given 25mg of MK-677 per day. Those taking ibutamoren saw a 60 percent increase in IGF-1 and HGH levels after just one week. The researchers also discovered that people who took the medicine had a better nitrogen balance than those who didn’t. The study’s findings show that it can be used to treat humans who are in a catabolic state.

Enhanced Fat Loss

Increased insulin-like growth factor (IGF-1) and growth hormone levels cause fat loss to increase (source).

According to the same study mentioned above, those taking MK677 shed much more fat than those in the control group after 14 days. Therefore, athletes that take this supplement will lose fat at a faster rate than usual.

Increased Muscle Growth

Bodybuilders are well-known for using HGH to acquire massive quantities of muscle mass prior to competitions. In this way, MK 677 is no exception. Your body’s HGH levels will skyrocket as a result of taking it, and you’ll gain muscle faster than you ever imagined.

Become Taller

Ibutamoren appears to be a promising alternative to HGH replacement therapy for those seeking an alternative to HGH replacement therapy. Taking it before the growth plates close will allow males to grow taller. This is to be expected, as MK 677 permits the body to produce far more HGH than it would naturally.

Suitable for All Year Use

One of my favorite things about MK 677 is that it doesn’t have to be turned on and off. Because it does not interfere with your body’s natural testosterone production, it is typical for people to never come off of it. There are several testimonies on the internet of people who have used it for six months to a year with no adverse side effects.

Recovery Time is Cut in Half

You will not need to take nearly as many rest days as you would normally if you dramatically increase the quantity of IGF-1 and HGH in your body. To take advantage of this benefit, many people who begin using ibutamoren begin training twice a day.

Better Sleeping Habits

Proper sleep is one of the most crucial things for anyone wanting to grow muscle or lose fat. In fact, according to this study, not getting enough sleep can stifle weight reduction and prevent you from seeing improvements. MK 677 aids your body in reaching a deeper state of sleep. While it won’t make you fall asleep like a sleep aid, it will make your sleep more restful and deeper.

You Become Better Looking

Finally, many people who take MK-677 say that their skin glows and that their hair and nails appear to be healthier. This is because MK 677 boosts collagen production in the body, making you look younger than usual.

What are the Potential Risks of Using Ibutamoren?

Unlike steroids and other illegal anabolics, MK 677 does not have a lot of negative side effects. Elevated GH levels, on the other hand, can cause some changes in your body. However, stopping consumption can readily reverse these changes.

Here are some of Ibutamoren’s negative effects:

Increased Water Retention

Water retention is a common reaction when your body has high quantities of HGH flowing through it. The good news is that, like creatine, a large portion of this water is kept within the muscles. This is one of the ways that HGH can help athletes gain strength.

As a result, some water might be stored beneath the skin, resulting in a bloated appearance. However, at doses of 25mg per day, we rarely experience water retention or bloating, so aim to stay around that dosage.

Taking a diuretic, such as dandelion root extract can also help you feel less bloated.

Hunger Pangs

While this is beneficial for people on their winter bulking cycle, those attempting to benefit from MK 677’s anti-catabolic action may find this side effect irritating. It’s impossible to deny that ibutamoren makes you hungry.

Fortunately, this effect is only transitory and usually passes in about two weeks. As a result, we recommend starting your cycle two weeks before you begin dieting to get your appetite under control first.

Hands or Feet Numbness

Do not be alarmed if you begin to get “pins and needles” in your hands and feet. This is not a dangerous adverse effect, and a short Google search will reveal that it is a common growth hormone side effect.

While no one understands why this occurs, physicians agree that it is not harmful and has nothing to do with nerve injury.

Potential Anxiety

Although it is still debatable whether MK 677 produces anxiety, the majority of experts agree that it should not cause anxiety pharmacologically. There are no studies that indicate anxiousness as a side effect, and reports of it on the internet are few and far between. Anxiety experienced during a cycle is considerably more likely to be situational.

HGH versus MK 677

What are the most significant distinctions between MK 677 and HGH?

  • Typical HGH must be injected, whereas MK 677 can be taken orally.
  • MK 677 can be purchased anywhere in the country, whereas HGH requires a prescription.
  • MK 677 just needs to be taken once a day, whereas HGH takes many dosages throughout the day.

Oral vs. Injections

HGH must be injected beneath the skin (not into a vein), whereas nutrobal must be taken orally. This is a deciding factor for many people when deciding which path to choose. Using an oral solution rather than injections is more convenient for most people.

Frequency of Dosing

MK 677 should be taken once a day orally. HGH is administered through injections, which must be repeated on a regular basis. Many bodybuilders even inject HGH up to five times a day!


Genuine HGH is too pricey. You should expect to pay $500 per month in copays with insurance and thousands of dollars per month without insurance for your medication. MK 677 is far less expensive than HGH. The approximate monthly cost of a genuine MK677 is between $50 and $100.

What kind of outcomes can be expected when utilizing Ibutamoren?

You should know what to expect before going on the ibutamoren bandwagon. You’ll know straight immediately if you’re taking the proper compound, if you’re conscious of the changes that occur in your body, and you’ll have improved body awareness. When you use MK 677, you can expect the following outcomes:

  • Gaining muscle mass, particularly in the arms and back
  • Sleep quality has improved (REM and deep sleep)
  • It increased collagen production resulting in clearer skin.

Let’s take it a step further and tell you what to expect based on the type of cycle you’re on:

Results of the Bulking Cycle

For an eight-week cycle, those who use MK 677 for bulking can easily acquire 10 pounds. Water will account for some of its weight.

On top of that, you should anticipate some strength boost while on cycle. The majority of people experience no adverse effects, although you may experience increased hunger and water retention.

We recommend that you eat a high-protein diet and not be afraid of carbs (especially post-workout). This will allow your Nutrobal to shine and provide you with the desired effects.

Results of the Cutting Cycle

Those who use ibutamoren for a trim will notice that they retain a lot of muscle while shedding fat. Fat will be eliminated faster, and many people will acquire a few pounds of muscle in the process. You won’t acquire a lot of muscle on a cut, but you may rest assured that your strength won’t suffer.

Cutting cycles should be accompanied by a diet that is extremely high in protein. To help you lose weight, we recommend eliminating simple carbohydrates like white bread and sugar from your diet.

What is the Appropriate Dosage for Ibutamoren?

People will advocate a daily dose ranging from 10mg to 100mg, depending on where you look. Fortunately, there is a study that compares HGH levels between doses.

The research shows that with higher doses, there is a significant declining return. The amount of HGH and IGF-1 that enters the bloodstream decreases when you go above 25mg per day.

As a result, the optimal MK 677 dosage is 25mg per day. This dose will provide you with all of the benefits without putting you in danger for water retention and bloating.


MK 677 is sometimes misidentified as a SARM, but it’s actually a highly potent growth hormone secretagogue. Because of its propensity to enhance GH and IGF-1 levels, it has attracted a lot of attention in recent years.

Athletes that wish to enhance their recuperation time, muscle growth, and general performance may benefit from this.

For the effects of ibutamoren to be fully apparent, it must be taken for longer periods of time. Although it may have side effects, it does not interfere with your body’s hormones.

This substance is available from various sellers; however, we recommend purchasing it from a trustworthy source like Science bio.
