What is Ibutamoren MK-677

Ibutamoren, also known as MK-677 and Nutrobal, stimulates the secretion of growth hormone (GH) and increases insulin-like growth factor I (IGF-1). MK-677 is not actually SARM but is classified as part of the Selective Androgen Receptor Modulators (SARMs) group because Ibutamoren acts selectively and does not cause hormonal imbalance.

Ibutamoren MK-677 is one of the most sought after SARMs on the market due to its unique ability to mimic the action of the hormone ghrelin and thus bind to one of the ghrelin receptors in the brain. This causes the body to release solid amounts of growth hormone.

Another unique feature of Ibutamoren MK-677 is that it increases lean muscle mass without causing a change in body fat percentage - something that, as many athletes can attest, is extremely difficult!

What are the benefits of Nutrobal

It is difficult to give a short answer to the question "What are the benefits of Nutrobal?", Because they are really many! MK677 has a number of positive effects and this is one of the reasons why it is used even in the treatment of diseases such as osteoporosis, which lead to loss of muscle mass.

Hundreds of athletes around the world trust Nutrobal and are able to gain muscle mass while strengthening their joints and bones. Mostly due to its ability to increase the release of growth hormone, this SARM leads to many other benefits:

  • Increases PURE muscle mass

Anyone who has set a goal to gain lean muscle mass knows how difficult this is! The process of increasing muscle is not just long, but also associated with many other things other than training - proper nutrition, intake of a certain amount of calories and more.

Can Ibutamoren MK-677 be taken by professional athletes

Ibutamoren MK-677 is one of the best-selling SARMs on the market due to its great applicability in various sports. Professional bodybuilders maintain their shape with this supplement.

However, due to its great action, Ibutamoren MK-677, as well as other supplements in the SARM group, are included in the banned list of WADA substances, which turns them into doping.

This means that Ibutamoren MK677 should not be taken by professional athletes undergoing a doping test. An important clarification is that MK-677 remains in the blood for several months after the end of the cycle!

How Ibutamoren MK-677 works

How Ibutamoren MK677 works

Ibutamoren stimulates the pituitary gland, which leads to the release of large amounts of growth hormone. Although this SARM has a similar effect to that of the peptides GHRP-6 and Ipamorelin, it does not cause side effects and is taken orally.

Ibutamoren works by stimulating the release of growth hormone by binding to ghrelin receptors in the brain. Studies on this SARM show that it increases both muscle mass and bone mineral density.

The way Ibutamoren works makes it a potential treatment for older people who have bone and joint problems. Moreover, as of 2017, Ibutamoren MK-677 is officially in the preclinical stage of development for a drug for the treatment of growth hormone deficiency.

When are the first results of Ibutamoren MK-677 seen

One of the main reasons so many people are more than happy with a cycle with Ibutamoren is the fast results! First of all, after 3-4 days of intake begins to notice a significant improvement in sleep.

In terms of physical results, an increase in the density and volume of muscle fibers can be seen after about a week of intake. Fat burning begins to be felt and seen at a later stage, after about 3-4 weeks.

In addition to everything said so far, Ibutamoren MK-677 speeds up the metabolism and after the first week of intake you will feel increased hunger. This should not bother you, because the way Nutrobal works will prevent you from gaining weight in the form of fat.

Does Ibutamoren MK-677 inhibit testosterone production

Ibutamoren MK-677 causes the body to increase its own production of growth hormone by up to 300%. As a result, the body's cells are mobilized and stimulate the development and growth of bones, joints and muscles.

Hearing this, you probably think that Ibutamoren can't help but have a side effect on its own testosterone production. Well, surprise! MK-677 does not stop its own production of testosterone!

How to cycle with Ibutamoren MK677

Ibutamoren has a long half-life, which makes the cycle with it very easy to follow - taking once a day. In addition, you can choose whether to take the dose in the morning or evening. Generally speaking, we can divide the dose into two variants:

  • 10-20mg for women
  • 20-30mg for men

Of course, the dose also depends on the experience you have. If you are taking SARMs for the first time, it is recommended that you start with the lower dose. Keep in mind that Ibutamoren MK677 may cause a slight feeling of tiredness during the first few days of intake.

This is the reason why many users prefer to take Ibutmoren before bedtime. Given that this SARM speeds up the recovery process and improves the quality of sleep, this is a completely logical choice!

Muscle mass cycle

If your goal is to gain muscle mass, we can not fail to mention the fact that Ibutamoren is one of the most purchased SARMs for this purpose. It has an action similar to that of the GHRP-6 peptide, but is completely safe for your health and does not cause dangerous side effects.

The MK-677 works great on its own, but many people still think it's one of the best ancillary SARMs.

What does this mean?

Ibutamoren almost triples the effectiveness of any SARMs it can be combined with because of the high levels of growth hormone it releases.

How to determine the Quality Level of Ibutamoren MK677

Ibutamoren MK-677 QUALITY TEST

Determining the quality of Nutrobal, and of SARM in general, is not an easy task. Selective androgen receptor modulators are not controlled by law - that is, they are not defined as drugs or prohormones or steroids.

SARMs are a unique group of products, with an action that is very different from anything known. However, due to the fact that supplements are not regulated, many traders and companies allow themselves to dilute the raw materials to double the amount of product.

In order for a SARM to be "quality", it must contain a minimum raw material quantity of 97%. However, this quantity is difficult to determine without a quality test, so our advice to anyone who wants to determine the quality level of Ibutamoren is to check if the brand provides access to such a test.

What does "original" SARM mean?

As we have already understood, a SARM can be advertised as "quality" and "original", but in fact contains various harmful substances that change its effectiveness and safety.

But what does "original" SARM actually mean? It is a well-known fact that certain countries of origin inspire confidence in the customer.

Such countries are, for example, Germany and Great Britain. Is it a coincidence, then, that the vast majority of SARMs are advertised as "manufactured" there?

No, it's just a marketing ploy!

In fact, the raw material for SARMs such as Ibutamoren MK677 is produced in Asia.

Exactly! All the raw material! This means that products that are said to be "original" because they are made in the UK are just as original as any other supplement!

The countries you see on the label do not show the country of origin! They simply show where the product was most likely packaged or encapsulated. The real quality of Nutrobal MK677 and other SARMs depends on the traders and brands themselves, which brings us back to the mandatory quality test!

Where to find a forum with opinions and reviews about Ibutamoren MK-677

Of course, there are other ways to check how good a SARM is like Ibutamoren, for example from the opinions and reviews of other users. Here, however, the situation is not so rosy.

Where can you find real opinions and reviews about the MK - 677? In the unique SARM forum! The SARM forum is a neutral place where everyone can find information related to:

  • Opinions on how MK-677 works

What are the side-effects of Ibutamoren

MK-677 side effects

Ibutamoren MK-677 mimics hunger hormone and increases the release of growth hormone. This means that while taking Ibutamoren MK677 it is completely logical to have an increased appetite as a major side effect.

Ibutamoren mimics the anabolic effects of prohormones and steroids. This SARM targets certain receptors and changes their way of functioning in the body. Ibutamoren MK677 does not cause the side effects caused by peptides and synthetic growth hormone!

It's perfectly normal when looking at a new sports supplement to want to know what its side effects are. The information on the Internet that is given about Ibutamoren MK-677 is quite often misleading and only 10% of the listed side effects are real.

Real side effects of Ibutamoren

Ibutamoren does release a lot of extra growth hormone, without depleting existing reserves. However, high levels of HGH can really lead to some real side effects.

These side effects also occur in people who normally have elevated levels of growth hormone. They are:

  • Swelling of the joints
  • Pain or slight tingling in the limbs, most often the hands

Various studies on the effect of Ibutamoren also show that you may experience a decrease in insulin sensitivity and an increase in blood glucose.

How to do therapy after a cycle for Ibutamoren mk-677 PCT

There is a reason so many people are happy with Ibutamoren's action! Apart from all the positives that its intake leads to, a big plus is that it acts without affecting secondary organs, which in turn means that post-cycle therapy with Ibutamoren is not mandatory.

It is important, of course, to follow the recommended doses to ensure a safe and impressively effective intake:

  • For men: 20-30mg per day

  • Vitamin D3 - 2000 to 5000 iu Daily
  • Zinc 30 to 45 mg daily

Ibutamoren MK-677 is suitable for both women and men. As well as being really effective on its own, Ibutamoren is the ideal SARM for stacking, as it perfectly complements the action of a number of other SARMs.
