MK-677 (Ibutamoren) | Dosage, Before and After, Side Effects and Results

By  //  November 10, 2021

A brief introduction of Mk 677

A quite popular product, known as Ibutamoren or MK-677, comes for discussion in today’s article/review. 

A member of the SARM family has become very popular in sports (and especially in the field of Bodybuilding, Weightlifting, and in general in all sports requiring muscle rebuilding and strengthening the body [Mass Gaining]).

Ibutamoren (MK 677) is a non-peptide of spiropiperidine acting in the body as a “catalyst” for the production of more growth hormone HGH (Human Growth Hormone).

This increase in growth hormone then leads to an increase in the levels of IGF-1/insulin-like Growth Factor-1.

However, the action of (MK-677) is shown below in more detail, as well as the benefits offered and its potential effects on the organism.

First, we explore the preparation, where you find it and whether (or not) its use is legal. 

SARM MK677 – is it Legal?

Ibutamoren (MK-677) is a SARM, a chemical product that – to a large extent – imitates the anabolic steroids known.

SARMs have become very popular in recent years, promoted as “the new generation of anabolic substitutes, with a lower risk”.

We’ll see what this means further below.

At this point, we should clarify if the use of SARMs (including Ibutamoren) is legal.

SARMs are selective androgen receptor modulators, products of extremely strong chemical composition, delivering results of intense muscle growth/targeted fat loss/massive athletic stimulation.

It is not a coincidence that is preferred by athletes, and people interested in their look (models or celebrities).

There is a rumor that SARMs are completely harmless, not causing any side effects.

Nevertheless, this is not the case in reality.

The strong chemical composition of SARMs is similar to that of anabolic steroids and – although significantly less risky than steroids – remains quite dangerous and with a risk of provoking side effects.

Their lower “destructive” effect on the organism compared to that caused by steroids is due to their selective action.

Thus, SARMs, according to scientific research to date, appear to cause less hormonal and prostate damage.

They also do not seem to cause acne or liver toxicity.

In any case, is their use legal?

No. From a medical point of view, SARMs have not yet received the necessary marketing approval from the FDA (and this is why most of them do not have regular names but alphanumeric names).

Although SARMs started existing much earlier than we think (since World War II), they are still under investigation and not legally available for medical use.

MK 677 – What it is – Before and after Results

MK 677 is the alphanumeric name for a chemical of the SARM family, also known as Ibutamoren, which – according to experts imitates the performance of a specific hormone (Ghrelin/Ghrelin hormone).

Ghrelin – also known as the “hunger hormone” – is a peptide synthesized by ghrelinergic cells in the gastrointestinal tract.

Its action is located in the CNS (Central Nervous System) as a neuropeptide, acting as an energy “regulator” in the organism (its distribution in different parts of the organism, consumption rate, production).

This hormone – extremely important for the organism – consists of 28 amino acids and has been modified by a molecule of caprylic acid in serine (position 3), while its title as “hunger hormone” is by no means accidental.

Ghrelin contributes in a unique way to the management of appetite levels, as well as to the control of body weight.

In addition, according to clinical studies, it plays a very positive role in situations of depression/psychosis/neurosis.

Thus, SARM MK 677, imitating the performance of the naturally produced hormone of hunger, ghrelin, promotes the production of a very beneficial (especially for those exercising) growth hormone.

According to the scientists, the data obtained from the research to date, do not find differences between the strong chemical ghrelin receptor chemical agonist MK 677 and the natural ghrelin hormone of the organism (giving them exactly the same properties).

However, what are these properties of ghrelin imitating the MK 677 ?

As already mentioned, ghrelin is produced in the gastrointestinal tract, and then diffuses into the bloodstream.

Therefore, as it enters the bloodstream, it also passes via the hypothalamus of the brain where it functions as an appetite “regulator”.

Essentially ghrelin is the main responsible hormone leading to those amazing consumptions of more calories, eventually stored in the body as fat.

MK-677 (Ibutamoren) – controlling ghrelin – enhances the organism’s ability to rebuild muscle, promoting the burning of body fat for producing beneficial energy, and preventing the waste of muscle mass.

Another important benefit of using this SARM is the increase in growth hormone produced.

Increased growth hormone or somatropin, also means increased bone density, muscle growth, improved cell regeneration and psychology/mood, enhanced fat metabolism, boosted immunity and – certainly = higher athletic performance.

Equally important is the fact that the Ibutamoren product helps to reduce the feeling of uncontrollable hunger and body fat (total body weight as well), however, without increasing the concentration of “bad” hormones, such as the “stress hormone” (cortisol).

SARM (MK 677) – How it works

The chemical product SARM MK-677 Ibutamoren acts as an enhancer of the organism’s hormonal state for increasing the production of a specific hormone (growth hormone / HGH).

MK-677 may be a less dangerous substance than an androgenic/anabolic steroid, but it is still a very strong chemical (potentially harmful to the organism).

The legalization of this substance, not yet approved, is still under extensive scientific research on its potential effects (short and long-term) on the user’s health.

Due to its chemical structure, the MK-677 works by stimulating the brain (specific areas of it); resulting in an increase in the organism’s natural production of growth hormone, while also leading to a higher production of IGF- (an insulin-like growth factor).

SARM MK-677 Ibutamoren – according to studies – seems to affect the entire body and not just specific muscle tissues, with nearly every muscle tissue in the body experiencing the “push” from SARM.

Among the tissues positively affected by the use of MK-677 Ibutamoren are surely all the muscles, as well as the bones (increasing their density due to the growth hormone).

Referring to “universal” strengthening of the body, we do not exaggerate, as Ibutamoren helps in various areas of body function, such as:

the enhancement of bone density

improved muscle rebuilding

increased physical strength and endurance

improved REM sleep and the avoiding various sleep disorders

increased IGF-1 production (within less than two (2) weeks)

increased body fat burning (subcutaneous and visceral fat)

improvement of nitrogen concentration

reduced nitrogen waste and improved waste recovery

skin health

SARM Ibutamoren (MK-677) – Benefits of use

SARM MK-677 Ibutamoren may not have received official marketing approval yet, but that does not mean that it is not already (illegally) used by many bodybuilding athletes and not only.

Finally, does the MK-677 really have any benefits?

Certainly it has, almost equivalent to those of the known steroids.

In general, athletes (professionals or non-athletes) seem to select this particular SARM due to the amazing boost provided to the user’s athletic performance, while at the same time promoting the reduction of body fat and the increase of lean muscle mass.

In addition, it promotes good brain function (concentration, memory, complex thinking, problem-solving ability), assisting the athlete’s competitiveness.

Nevertheless, better not talk in general terms and examine the “tangible” benefits of using MK-677/Ibutamoren.

Muscle Protection / Strengthening / Reconstruction

Although not reaching the performance of steroids in “building” muscles, MK 677, brings very important results in muscle reconstruction and in the protection against waste of lean muscle mass, as well as in their rapid healing (after hard training).

The cause is the increased production of growth hormone, as well as the production of the insulin-like growth factor IGF-1.

The more “hard” and painful the workouts, the greater the need for faster recovery times, improved repair & of course increased protection.

Physical Strength and Athletic Endurance

As MK-677 delivers benefits similar (almost equivalent) to those of an anabolic steroid, as expected, it also has a positive effect on physical strength and endurance.

We are referring specifically to athletic endurance mainly because exclusively athletes use it (even illegally).

In addition to massive muscle gains, the increase in growth hormone (HGH) produced, leads to enhanced physical strength & endurance and therefore to improved athletic performance.

The MK-677 / Ibutamoren can help you “make the most” of your training time, and make your workouts offer double benefits.

Reduced Muscle Waste

A very big risk for all athletes is muscle waste.

In any case, what do we mean by this term and how this waste comes about?

By “muscle waste”, we mean the burning of muscle tissue to produce the required energy.

When the body has nowhere to pump the required amounts of energy, this inevitably leads to the burning of muscle tissue.

This risk becomes even greater when the training requirements increase (therefore the energy required for performing the training) or when the person follows a low calorie diet for weight loss.

You will often hear athletes “complaining” about such muscle loss/waste.

What is wrong?

In these cases, it is the training program, the nutrition program, or even their combination, which could be wrong, requiring reorganization (ideally by a specialist).

The SARM supplement MK-677 / Ibutamoren prevents muscle waste by providing the organism with large amounts of energy, preventing the catabolism of proteins, a fact certified through relevant scientific studies and clinical trials.

Targeted and mass fat burning

A big issue for any athlete – a basic condition for achieving a flawless muscular body – is the burning of excess (accumulated in various places) body fat.

Ibutamoren is a favorite choice of men trying to build a slim and muscular/strong body.

According to the reviews of its users so far, this SARM, supports a massive loss of body fat (subcutaneous and visceral) to produce beneficial energy (extremely useful especially in intensive/hard training).

However, the most important point – a point worth paying special attention to – is the protection of lean muscle mass from “collateral” losses.

The SARM MK-677/Ibutamoren is extremely “muscle friendly”, even in super-intensive workouts.

Supports fat loss without putting your muscles at risk.

Enhanced Bone Density

Another very important benefit of using the SARM MK-677 / Ibutamoren is the increase in bone density to avoid injuries (more or less serious) that could keep you out of training, achieved by improving bone quality.

We generally talk about people in the field of sports or championships, but a supplement such as SARM MK-677 / Ibutamoren, is especially useful in women during the menopause (where the bones decrease in density), in individuals (men & women) older in general or even obese/overweight people straining their skeleton due to their increased body weight.

However, strengthening the bones has to do not only with potential injuries, but also with the general health of the individual.

Any side effects caused from Mk-677? Could it be dangerous for my health?

In general, we would say that SARM MK-677/Ibutamoren is a product of moderate risk, clearly less dangerous than an anabolic steroid, but remaining potentially dangerous (possibly harmful as well) to the organism, its proper functioning and to the long-term state of the user’s health.

As a SARM, it does not cause the serious side effects of a steroid anabolic, this being the main reason that (even without an official approval for release and use) has already become such a popular and highly preferred product in sports.

However, this does not mean that MK-677 is unlikely to cause side effects or that it is completely harmless in terms of long-term damage to the organism.

This chemical is still in the research phase to clarify both the benefits provided and the potential harm possibly caused to the organism.

Some first data (according to the reviews of its users so far and to clinical studies carried out in a laboratory environment) confirm some side effects following its use.

The most basic (and confirmed) are:

increased fluid retention

anxiety and increased anxiety

severe headaches/migraines

a feeling of lethargy

bloating and feeling of indigestion

increase in blood sugar levels

decreased insulin sensitivity

increased feeling of hunger

Could these Side Effects of MK677 be avoided and How?

Unlike anabolic steroids, SARM MK-677 (also known as Ibutamoren) does not cause as many “catastrophic” side effects directly to the user’s life.

In fact, with the data to date, the occurrence of side effects seems to be more the result of overuse, long-term use or misuse of the drug.

Side effects from the combined use of SARM MK677 / Ibutamoren with other chemicals (i.e. not of its pure chemical form) also reported.

However, although its use does not seem to be so harmful to the organism (especially if done in the right way and the right dosage), we strongly discourage its use.

SARM MK-677 / Ibutamoren – Is it legal?

SARM MK-677/Ibutamoren is much safer than anabolic steroids, however, not completely “innocent”.

It is still under investigation and the impact it may have on the user’s health is not yet clarified (especially after long-term use, as is the case with athletes).

Therefore, while it does not because of the side effects of an anabolic steroid, it is still a product not yet been approved by the FDA for a good reason.

Both anabolic steroids and SARMs remain banned and illegal.

In fact, their use (in official sports events) is detected by special bodies (WADA) and prosecuted.

In the market, however, you can find a variety of legal (OTC) over-the-counter supplements to get the athletic boost needed and without any risk to your health or life.
