MK-677 Review: Boost Your Natural Growth Hormone

How Does MK-677 Work?

MK-677, also known as Ibutamoren, Ibutamoren Mesylate, or Nutrobal, is not really a SARM but is a growth hormone secretagogue. This means that instead of binding to the elective androgens like Selective Androgen Receptor Modulators do in order to bind to selective tissues, this molecule actually binds to ghrelin receptors.

Ghrelin receptors are your body’s natural growth hormone secretagogue, so by binding to this molecule, MK-677 causes the body to produce natural growth hormone. The additional production of extra growth hormone in the body leads to improved memory, biological rhythms, mood, appetite, and cognitive function.

As you can see, this is much more than just a replacement for a steroid. The rest of this Mk-677 review will show the benefits, dosage, cycling, results, and more.

Benefits of Using MK-677

Using SARMs gives bodybuilders the chance to design molecules that are taken in a liquid or pill form that target specific androgen receptors and tissues differently. The goal of this is to get a customized response where only the targeted muscles will respond to treatment rather than all the tissues in the body.

This is in comparison to steroids which affect every part of the body. This comparison has been likened to a shotgun (steroids) versus a very precise sniper bullet (SARMs). This means there are fewer side effects when using something other than steroids which is very beneficial for bodybuilders.

As previously noted in this MK-677 review, Ibutamoren is not technically a SARMs because it works on the ghrelin receptors, but it is marketed as one usually so we will treat it as such. MK-677 has the benefits of SARMs in that it doesn’t have the nasty side effects of steroids. In fact, there are no chances of danger or damage to the liver, kidneys, or prostate when taking MK-677 like there could be when taking other steroids.

MK-677 actually has some natural benefits to it that many people enjoy while taking it. In addition to helping increase fat-free mass, or pure muscle, MK-677 also can improve the user’s quality of sleep, lower their bad LDL cholesterol, improve muscle, bone, and ligament healing, improve the appearance of hair and skin, and improve an overall sense of well-being.

In addition, MK-677 does not cause pituitary sensitization or suppress the user’s body’s natural production of Growth hormone.

MK-677 can also be used by people who experience muscle wasting not related to the bodybuilding field. It could be beneficial for those who are food-deprived, people with illnesses that cause muscle wasting like cancer, and the elderly.

What are the Dosage and MK-677 Cycle Options?

MK-677 has a half-life of 24 hours. In addition, as soon as the user takes it, it instantly raises levels of growth hormone in the body. This is both good and bad.

The good part is that it does what it is meant to do, which is to raise growth hormone, in an effective manner. The bad part is that this can lead to a severe energy crash later. For this reason, it is recommended that the dose either be taken at night right before bed or split into two and take half the dose in the morning and half the dose in the evening.

Now you may be wondering what the proper MK-677 cycle is to determine your dose. This depends on what your goals are with taking MK-677 and what MK-677 results you are trying to get. There are six different MK-677 cycle options that can determine your dosage.

  1. The first cycle option for optimal results, the user should start with 10 mg per day for the first few weeks, and then increase to 20-25 mg per day later. This is a 12-week MK-677 cycle.
  2. The second cycle option is if the user is trying to have a cycle that is longer than 12 weeks. This user can start with 15 mg per day and maintain that dosage in order to have a cycle longer than 12 weeks.
  3. The third cycle option is for bodybuilders that are coming off a cycle of something else, they can take a dose of 50 mg per day for an 8-week cycle.
  4. The fourth cycle option is if the user is looking to build muscle. This user should take 30 mg per day.
  5. The fifth cycle option is if the user is looking to lose fat. This user should take 20 mg per day.
  6. The final cycle option is if the user is trying to heal from injuries. This user should take 10-20 mg per day.

Are There Any Side Effects to be Concerned About?

For a perfectly healthy individual, there have not been many side effects observed in regular users. Those that have been observed include a slight increase in appetite, a possibility for that afternoon slump or lethargic feelings, and numb hands. In addition, it could lead to muscle cramps or edema but this is only seen in users who have taken too much of it.

If you take MK-677 and are not a completely healthy person, it is possible that it could raise insulin levels, fasting blood sugar, and blood pressure levels. In addition, it could also cause swollen joints, numb or tingling skin, joint pain, water retention, and tired feelings.

Ibutamoren MK-677 Results You Can Expect

When users are choosing which SARMs to use, they want to know what results they are going to get from each one, and how fast they can expect to see these results. Bodybuilding is a very scheduled sport, and it matters how quickly you can see results.

When using MK-677 it is important for users to know that they are not going to see huge results when just taking MK-677 by itself. This is why many bodybuilders stack their different SARMs in order to get optimal results from Ibutamoren. MK-677 stacking will be discussed in the next section of this MK-677 review.

Most people that use just MK-677 by itself will see gains of about 6-8 pounds of lean muscle in 8 weeks. Now to an average person this might be incredible gains, and could be enough for the average gym rat just trying to add on a little muscle.

These gains would also be significant for the elderly, or sick patients like those with cancer who experience severe muscle and lean tissue wasting that can be detrimental to their health. These are important MK-677 results that are seen in the greater health community. However, for bodybuilders who are looking for maximum gains that are more than 6-8 pounds for an 8 week cycle, stacking your SARMs will come in handy.

Stacking Mk-677 with Other SARMs

As it was mentioned in the previous section, MK-677 is not known for getting very extreme results. You won’t put on upwards of maybe 8 pounds maximum when using MK-677 for 8 weeks on its own.

If this is enough for you, then you can just stop there and enjoy the benefits of MK-677 by itself. However, if you are looking for bigger gains, then it might be time to look into some stacking with MK-677.

Since MK-677 is not a true SARM, it can be stacked with other SARMs to maximize benefits. Two common possibilities to stack with MK-677 are Rad140 and S23. Rad140 is also known as Testolone. This SARM is used to boost testosterone levels in the body without the negative effects of anabolic steroid use.

Rad 140 is used to increase lean tissue, or muscle, as well as enhance the speed, endurance, and stamina of the individual. When it is stacked with MK-677 it forms a perfect combination for better body composition, muscle gains, anti-aging possibilities, and fat loss results.

S23 is another SARM that can be stacked with MK-677. S23 is known to work in the body to build muscle, reduce fat, increase bone strength, and can even work as male birth control in small doses.

In addition, it can be used to boost female libido when women experience a lack of sexual motivation after menopause. When S23 is stacked with MK-677 is optimizes muscle gains by supporting not only stronger, denser, grainier muscle, but also building muscle without putting on fat. This is important when trying to cut without losing mass.
