MK 677 is a newer muscle-building supplement on the market that has rising popularity for its potential to promote significant muscle mass gains without the use of steroids.

You know, MK 677 or Ibutamoren is commonly called a SARM even though it is actually a Growth Hormone Secretagogue. This means that it does not act like any other SARM because it isn’t one.

In recent years, MK 677 has become popular as a potential muscle builder. Some people believe that it causes permanent muscle gains, while others think the gains are only temporary.

SARMs will bind to androgen receptors in the body, whereas MK-677 will not. MK-677 will stimulate the pituitary gland to produce more natural Growth Hormone simply.

You will not be building any real muscle mass with MK-677.

Growth Hormone’s action for hypertrophy is somewhat disappointing.

While MK 677 can increase IGF-1 (Insulin-like growth factor 1) levels in the body, it will not increase muscle mass. If you’ve always trained or followed a high protein diet, there is a high chance it can lead to muscle gain.

So, why do people even use MK-677 then?

Does it have other properties that make it worth it?

Is it better than a normal Growth Hormone?

In this article, we’ll take a close look at the evidence to determine whether MK 677 really does build muscle mass with permanent gains. Read on to find out what we found!

Does MK 677 increase and build muscle mass?

Mk-677 is used in the medical sense as a treatment for growth hormone deficiency. Growth hormone is a vital hormone to the human body and will begin to lower past age 30.

A growth hormone deficiency can lead to side effects like fat gain, muscle loss, depression, and anxiety.

Bodybuilders have noticed that when normal Growth Hormone is used past a medical dose, you can get both hypertrophy and fat loss. Some say that Growth Hormone is the secrete behind sarcoplasmic growth. However, that has never been proven.

The reality is that you will probably not be building quality lean mass with MK-677.

Growth hormone, in general, is not incredibly powerful when accruing contractile tissue. Some studies support the idea that Growth Hormone could build muscle. However, these studies were mostly done on untrained and ill people.

Growth will have a far greater effect on fat loss and longevity.

How to use MK 677 for Muscle Growth

As I mentioned previously, MK-677 is known as a Growth Hormone Secretagogue.

This means that once it is administered, it will then cause an increased release of Growth Hormone and IGF-1 levels in the body, leading to muscle gain.

This is how the process works:

  • The Pituitary Gland produces HGH. This starts circulating through the body and reaches the pancreas
  • In response to the presence of HGH, the Pancrease dumps both Glucagon and Lipase into the blood. Glucagon is a hormone that helps regulate blood sugar, while Lipase is a protein that releases fat from fat cells
  • Lipase proceeds to release fat from adipocytes into free fatty cells in the bloodstream
  • Glucagon circulates in the bloodstream and reaches the liver
  • In response to the presence of Glucagon, the liver dumps sugar into the bloodstream. This proceeds to raise blood sugar levels
  • In response to higher blood sugar levels, the pancreas releases insulin. Simultaneously, the liver releases IGF-1 (Insulin growth-like factor 1)

When considering the process, you have more fuel in the body once you secrete a good amount of growth hormone. The best time to take MK-677 for muscle gain would be before bed. Your body can then use the fuel available in the blood to grow.

How much muscle can you gain on MK 677?

Honestly, not much.

When studies have been done using a massive amount of Growth Hormone (more than MK-677 would result), they found that muscle gain isn’t that much. Growth hormone is not nearly as anabolic as steroids and will not cause a fraction of the same growth.

You could gain 5 pounds after using MK-677 over 12 weeks, and 1 pound of that will surely be water.

Are MK 677 gains permanent?

Well, yes, with an effective exercise program and diet. When combined with a healthy diet and regular exercise, MK 677 results in significant body composition changes, including increases in muscle mass, decreases in fat mass, and increases in bone mineral density.

Most users will not experience any loss of muscle mass or strength once they stop using MK 677.

In fact, many users report that they are able to continue making gains long after discontinuing use. However, everyone is different and some may lose a small amount of muscle mass if they stop using MK 677 without continuing to eat right and train hard.

But as long as you keep up your good habits, the muscle you built while using MK 677 should be fairly permanent.

How fast does MK-677 start working for muscle mass?

MK-677 is known as a Growth Hormone secretagogue and is often grouped with SARMs. In reality, it is not a SARM and does not nearly have the same effects as SARM. This also means it probably is not as great at building muscle as SARMs are. Another thing to consider is that even pure HGH is not great at causing an increase in muscle mass.

Technically, you will see elevated levels of HGH and IGF-1 within a week of using MK-677.

So, you could see a small increase in muscle mass within ten days. That said, it is not likely to be much.

MK-677 is incredibly mild regarding anabolism and is more likely to be used for fat loss. It could be used to gain muscle, but it is less likely to be as effective as Anabolic Steroids.

Usually, bodybuilders would use a combination of Steroids with Growth Hormone to get the best results.

What should I stack with MK-677 to build muscle?

Stacking various compounds with one another is a common method used by athletes and bodybuilders to get the best results.

It is important to remember a few things when choosing a stack:

  • Do not stack compounds that have the same side effects
  • Do stack compounds that’ll create a synergy

In regards to Mk-677, there are various compounds to stack it with. The prime goal here is to increase the anabolic properties you encounter. MK-677 is not very anabolic itself.

Thus, the compounds you decide to stack it with, need to be pretty strong. Let’s take a look at some potential stacking options with Ibutamoren:

Stacking MK-677 with Steroids

This one is pretty self-explanatory. Steroids are quite anabolic, so combining them with increased HGH levels can result in some quality gains.

You could stack it with Testosterone and Deca if you are doing a bulk, or Testosterone and Primoolan if you are doing a lean bulk.

Stacking MK-677 with Insulin

We know that insulin can be extremely anabolic if used correctly. Using the right combination of insulin and HGH can result in serious gains and side effects if you use it incorrectly.

Stacking MK-677 with SARMs

If you are not keen on running the risks with Steroids or Insulin, then SARMs could be an option worth considering.

They certainly won’t be as strong, but they will be somewhat effective. You could theoretically stack MK 677 with any SARM on the market, seeing as there will not be overlapping side effects.

Does MK-677 help muscle recovery?

We know that one of the most important things about training is the recovery from training. If you fail to recover, you will never really grow. MK-677 could help a tiny bit with recovery, but overall, recovery will be determined by sleep and diet.

Any Side Effects of MK 677?

As with almost every other drug, there are side effects.

The side effects of MK-677 are broadly the same as HGH’s:

  • Insulin Resistance

Due to MK-677 causing insulin release into the bloodstream when blood glucose levels are increased, continuous use of MK-677 (especially in a hypercaloric state) can result in serious insulin resistance.

Doing this for too long can even lead to diabetes in extreme cases.

  • Edema

Both Growth Hormone and MK-677 can result in water retention via salt retention. This will lead to water retention around smaller body areas (like the wrists) and edema.

  • Carpal Tunnel Syndrome

Due to the water retention, it is not uncommon to suffer from Carpal Tunnel when using HGH or MK-677.

  • High blood pressure

Due to the water retention (and a hypercaloric and hyper-saline state), you could suffer from high blood pressure, which can damage your kidneys.

Legal Alternative to MK 677

MK-677 is sold under the term “research chemical,” While this is legal, some would want to use compounds with fewer side effects. For this, we would recommend the legal SARMS products over at CrazyBulk.

They have a collection of products that are equivalent to SARMs but will not be causing you any of the side effects.

They have a Growth Hormone booster called Ibuta 677 (discount link) with natural ingredients that can boost your natural HGH production slightly, leading to better fat loss and muscle gain.


MK 677 is known as a SARM, but it is actually a Growth Hormone Secretagogue.

This means that it stimulates the body to produce more growth hormones. As we have seen, MK 677 can be an effective tool for building muscle mass, but ONLY with a consistent workout and healthy diet. It has also been shown to improve sleep quality and increase bone density.

If you are looking for a safe and natural way to improve your health and fitness, our safer and legal IBUTA 677 may be the right choice for you.
