Introduction to Ibutamoren (MK-677)
Contrary to popular beliefs, Ibutamoren is actually a selective ghrelin agonist and not a selective androgen receptor modulator. So many online platforms categorize this substance as a SARM which is very misleading. This perfectly summarizes the entire supplements and steroid industry where there are so many substances sold under either misleading or inaccurate information.
If you are going to put your health at risk by consuming some powerful substance whose formula you can’t even comprehend, it’s only fair that you get to learn as much about it as possible, don’t you think?
The truth is that Ibutamoren is indeed an effective performance enhancement substance with numerous benefits but it can also be very dangerous for your health. With that in mind, here is everything you need to know about MK677.
Ibutamoren is also commonly known as MK677 or Ibutamoren Mesylate. It targets ghrelin receptors and that’s why it is referred to as a ghrelin agonist. Interaction with these receptors leads to the release of Growth Hormone through hypothalamic receptors and pituitary gland. In case you don’t know, the Growth Hormone, as its name suggests, promotes the development of different tissues inside the body. This is achieved through the production of Insulin-like Growth Factor 1 (IGF-1) which enhances the production of cells to make the tissues.
How is any of this helpful for bodybuilders? Well, when a compound such as MK677 is introduced into the system, it stimulates your body to promote tissue production beyond its normal limitations. Theoretically, this means that your body will be in a position to produce more muscle mass than it can do under normal conditions. In addition to that, the muscle gains can be achieved a lot faster thanks to the perceived potency of Ibutamoren.
Since MK677 is a ghrelin agonist, you can also expect an increase in appetite because this hormone is responsible for appetite stimulation in the body. Therefore, when taking Ibutamoren, you can expect to have higher cravings and this means that weight gain is also a big possibility.
- Increases muscle mass
- Increases muscle strength
- Improves bone density
- Increases longevity
- Enhances cognitive function
- No negative side effects
Effects of Mk677
One major drawback about MK677 is the limited clinical research on it. We know that it helps to stimulate the production of growth hormone but there isn’t enough data to show just how beneficial this will be for performance enhancement.
Therefore, most of the benefits of this substance are based on controversial information. There is some anecdotal evidence showing that MK677 is very effective for muscle growth but we also have quite a number of bodybuilders who reported zero positive outcomes after using it.
Anyway, the following are some of the possible benefits that you can expect from Ibutamoren:
- Increase Muscle Growth
Growth Hormone and IGF-1 are very crucial for the maintenance of lean body mass. This is the basis upon which the muscle growth effects of Ibutamoren are based on since the substance is known to stimulate the production of both hormones.
Again, there isn’t enough data to show how an increase in either of the two hormones directly leads to more muscle growth. For instance, one published report shows that Ibutamoren increased growth hormone but there wasn’t any impact on muscle growth. The only noticeable effect is that there was improved maintenance of lean body mass.
Most of the studies that showed an increase in muscle mass after taking Ibutamoren involved either older men (60 years or older) or other individuals with growth hormone deficiency.
- Promotes the health of tendons, bones, and ligaments
This is one of the less controversial benefits of taking Ibutamoren. Almost all bodybuilders have a story about how a certain injury delayed their progress by putting them out of the gym for weeks or even months. When you consistently spend a lot of your time in the gym, injuries are bound to happen. Additionally, the increase in muscle mass from your rigorous training regimen can also put too much pressure on your bones and other tissues leading to injuries.
The Growth Hormone is essential for the repair of damaged ligaments, bones and tendons. By increasing the levels of this hormone, Ibutamoren makes sure that your connective tissues are not just repaired from damages but they are also kept healthy. Your bone density will be improved significantly and this will benefit you in two ways. One, you will no longer be prone to injuries. Two, your bones will become strong enough to hold even more muscle mass.
- Boosts skin health
Your skin will also benefit hugely from the increase in growth hormone. You will see all the crow lines and wrinkles disappear resulting in a more radiating skin.
After a successful weight loss program, most people are usually left with a lot of loose skin. This not only affects how you look but it can also take a toll on your self-confidence. Ibutamoren is very useful on such occasions. It completes the perfect weight loss program by tightening up all the loose muscles thus giving you the sharp look that you deserve.
- Might improve oxidation of fat
Since it is widely known that Ibutamoren stimulates appetite, many people tend to stay away from this substance to avoid weight gain.
One purported benefit of MK677 is that it helps in the oxidation of fat thus preventing weight gain. Some reports even suggest that this ghrelin agonist will burn down stored fat to fuel your body. Again, there isn’t enough clinical information showing how exactly it achieves that.
Side Effects of Using Ibutamoren
There is always a risk that comes with using substances such as Ibutamoren. Some of the most common side effects here are decreased insulin sensitivity, lethargy, and muscle pain. People at a predisposed risk of cardiovascular conditions are also at risk of heart failure if they use this substance.
The good news is that the risk of these side effects is very low if you use MK677 as directed.
Individuals with a history of cancer or under treatment of the condition should not take Ibutamoren. This substance increases the production of growth hormone and IGF-1 and this can promote the growth and spread of cancer. Pregnant and breastfeeding women are also discouraged from using this substance. You should also consult your physician before using MK677 in case you are under any other medication.
Ibutamoren is available in capsules and hence you don’t have to worry about injections as is the trend with most other performance enhancement substances. The recommended dose is 25mg per day which can either be taken at once or split into two; half in the morning and the other half in at night. Any dose above increases the risk of adverse reactions.
A typical cycle of Ibutamoren usually goes for around 8 weeks.
The information on the benefits of Ibutamoren is limited but some people have reported incredible muscle growth from using it. Therefore, it’s not guaranteed that the substance will work for you but you can still give it a shot and see how it goes. If you don’t have the time to experiment, you can go for a more proven substance.
