Ibutamoren (MK-677): The Shocking Truth

Ibutamoren (MK-677): The Shocking Truth

03 / 12/ 2019

Before we tell you everything you need to know about Ibutamoren, let’s clear up a few misunderstandings about this compound.

MK-677 is also referred to as Ibutamoren, Ibutamoren Mesylate or Biogenetix. Don’t get confused guys, these are all the same compound – just different names.

Even though Ibutamoren is marketed as a SARM, it is not. It’s actually a growth hormone secretagogue. That’s right, MK-677 does not belong to the SARMs family.

The reason why Ibutamoren is so special is that it has the ability to stimulate growth hormone levels (GH) and Insulin-like growth factor (IGF-1). You might be skeptical, I don’t blame you as we all know there aren’t a lot of compounds that have the ability to raise GH.

Ibutamoren has actually been backed up by clinical studies.

Ibutamoren is a growth hormone secretagogue. A Growth hormone secretagogue (GHS) is a compound that acts as a secretagogue which will help promote growth hormone levels.

Growth hormone is needed for the body to perform optimally. It plays a crucial role in the development of muscles and tissue.

It’s a quite complicated process but what you should know is that Ibutamoren does not interfere with other biological processes such as natural hormone production. This means that you will experience a boost in GH levels without side effects such as testosterone suppression.

It’s currently legally available as a research chemical. This is why you will see a lot of vendors market it not for human consumption.

One of the primary benefits you will experience from MK-677 is increased muscle growth. Due to the fact that Biogenetixincreases GH and IGF-1 levels you will be able to put on size much easier. This has been backed up by science, a lot of user experiences show us that Ibutamoren does have a positive effect on building muscle tissue


Another benefit you can expect from MK-677 is an improved sleep pattern. It has been proven that Biogenetiximproves sleep quality. Having personally used MK-677 I can definitely back this up. I slept like a baby whilst researching with this compound. It’s also worth mentioning that the quality of my sleep was much better.

We all know a good night rest plays a crucial role in recovery, with Ibutamoren you will get plenty of sleep. If you are having trouble getting quality rest at night, Ibutamoren might help you fix this.


Growth hormone and IGF-1 have a positive impact on the skin, hair, and nails. GH has been proven to interact with the skin cells.


This benefit is solely based on anecdotal experiences. Some users claim that Ibutamoren helped them accelerate fat loss.


Because MK-677 (Ibutamoren) raises growth hormone levels, you can expect the following side effects:

Swollen joints

Numb and tingling skin

Muscle and joint pain

Increased water retention


These side effects are mainly caused by the elevated growth hormone levels in the body. Another side effect worth mentioning is increased appetite. Some users can get extremely hunger when using MK-677. Keep in mind, not everybody seems to have these side effects.

Having personally used Ibutamoren I can safely say it does. An hour or two after my MK-677 dosage I would get VERY hungry and it was very difficult to control my hunger. Especially once the dosage is higher (20-30mg) you will experience this side effect. If you are having a hard time reaching your daily calorie intake this compound will assist you in reaching your goal.

MK-677 might also be useful in treating catabolic conditions.


Biogenetix (MK-677) has become extremely popular in bodybuilding. The main reason why MK-677 is being used in bodybuilding is for the sole purpose of increasing GH levels. In bodybuilding, it’s all about being the biggest and leanest.

With growth hormone playing a key role in building muscle, you want it to be as high as possible whilst staying safe. The higher your growth hormone levels, the easier you will pack on extra muscle mass.

Because Human Growth Hormone (HGH) is very expensive there aren’t any alternatives for boosting growth hormone, except for Ibutamoren. Ibutamoren (Biogenetix) is much cheaper compared to actual HGH and can significantly boost growth hormone levels, which is just what bodybuilders want.

Besides that, you can easily purchase MK-677 online. It’s legally available as a research chemical. You will see a lot of bodybuilders that use Biogenetix and claim it’s for research purposes only.

It’s also worth mentioning that MK677 is often stacked with SARMs.

A good example is a combination of Ibutamoren, RAD140, and S23.


It’s safe to say that the results you can get from Ibutamoren are very impressive. It is a very effective compound because not only does it positively impact muscle growth, but it also helps with burning fat and improving skin and hair.

MK677 Results

Here’s a great example of MK677 results. This guy was able to change his body composition with the help of Ibutamoren. He was able to gain a significant amount of muscle whilst also losing some body fat.

Why does Ibutamoren give great results? It all comes down to the increased growth hormone levels. Most people overlook the importance of GH in the human body. It’s essential for growth, cell production, and regeneration. If you want to have the best results, it has to be taken for multiple weeks to months.

When MK-677 is stacked along with other SARMs such as LGD-4033 or MK-2866 it has the ability to completely change a physique, giving crazy results. Keep in mind, in order to get the best results with MK-677 you should prioritize diet and working out.


Based on the research I have done, 20 to 30mg seems to be the most optimal dosage. There are reports of people taking more than 30mg of Mk-677 a day, but it did not yield in better results. What’s even more important than the dosage is the length of the cycle.

It’s extremely important that MK-677 should be taken for a longer period of time. The growth hormone levels have to gradually build up in your body, which can take up to several weeks before you start feeling the effects.

If you are new to experimenting with Ibutamoren I would suggest starting with 10mg to see how your body reacts to it.

If you are curious to learn more about megadosing MK-677, have a look at the following video. In this video, they discuss what the impact of 50mg Mk-677 a day can have. In my opinion, this is a too high dosage and I definitely do not suggest trying it out.
