Safety results from studies

Short answer, MK 677 is considered a safe compound by studies and other research. It’s even going into clinical trials and has had numerous human trials in the past, obviously, this means that it’s safe for people.

Let’s break that down a bit more in-depth.

There have been a lot of studies done on MK 677 (Ibutamoren). In fact, it’s considered safe enough that it’s going through clinical trials to soon become FDA (Food and Drug Administration) approved. But for now, it’s not FDA approved yet.

A lot of studies are even doing human trials (testing the compound on people). Here are four studies, some of them as recent as 1 year ago, that confirm the safety of the compound by doing human trials.

You should keep in mind, however, that MK 677 is only safe at normal dosages (up to 30-40mg a day maximum). Cycle length doesn’t matter because the compound is safe even for very long periods of time. In fact, some people even take it for a year or two, without stopping. For example, those who want to grow taller (of course only young people with open growth plates) take it for a year or two. You can read our article about MK 677 height growth for more information. If you take it for a long time, you have to be careful about water retention. We will talk more about this later in the article.

To summarize, MK 677 ( Ibutamoren) is considered safe by every study. In fact, it’s considered so safe that it’s currently in clinical trials and has successfully passed numerous human trials. An important thing, however, is that you don’t go over the recommended dosages (up to 30mg a day, maximum 40mg a day) to avoid bad side effects. Cycle length doesn’t matter with this compound, you can safely take it even for years without stopping.

Now let’s go over the side effects of MK 677 and explain if they pose a safety threat or not.

Water retention

When it comes to “dangerous MK 677 side effects” this is actually the only thing you have to worry about. But it’s not that bad. Water retention can raise our blood pressure but this only happens if the water retention is persistent for a long period of time (up to a year).

MK 677 is known to cause water retention in some people. This isn’t necessarily dangerous because it will go away on its own in a couple of week after the cycle. It can be potentially bad if you intend to cycle for a very long period of time, but even then, you can easily avoid that by drinking more water.

So if you experience this, drink more water and you’ll be fine. You can read more about this topic in our article about MK 677 water retention.


Some people claim that they experience headaches on their Ibutamoren cycle. This can be because of water retention (what we talked about previously in this article), but that’s very rare and can only occur if you have water retention for a long period of time.

The more probably thing is that they have a bunk product. This is why it’s so important to buy pure, high-quality compounds – to avoid unnecessary side effects like this.

You can read more about this topic in our article about MK 677 headache.

Increased hunger

This isn’t really a side effect for many people. For a lot of skinny people, this is a benefit because it makes it easier for them to eat more food. If it’s a bad thing for you, make sure to take your MK 677 dosage before going to bed, this will avoid the increased hunger effect.

But when it comes to safety, this isn’t dangerous at all. It’s actually a very normal thing to experience in the first few weeks of your MK 677 cycle. Basically, you don’t have to worry about this.

How to make sure your MK 677 cycle is safe

Now that we have covered the safety of MK 677, let’s go over two important tips. Follow these two tips and your Ibutamoren cycle will definitely be safe.

Follow these two points to make sure that your MK 677 cycle will be completely safe.

  • Normal dosages
  • Buy high-quality, pure MK 677

The first point is obvious, too big dosages of anything can be dangerous to our health. You should keep your daily dosage of MK 677 at normal ranges (up to 30-40mg a day). You don’t have to worry about cycle length because this compound can be cycled for long periods of time, some people cycle it for more than a year. But if you do that, you have to keep an eye on water retention, if you see it, drink more water.

The last point on the list, buying a high-quality, pure MK 677 is also very important and is the part where a lot of people go wrong. Some companies sell bunk products with other substances mixed in them that reduce the effectiveness and raise the side effects of the compound. Buying high-quality products will make sure that you will have great results and won’t experience any unnecessary side effects.

Now let’s go over some MK 677 cycle examples that are completely safe.

Let’s go over the example cycles:

Remember, the cycle length in the example cycles is 16-weeks. You can cycle Ibutamoren for much longer if you wish but 16-20 weeks will be enough for a decent cycle.

Cycle #1 MK 677

Cycle #2 MK 677 + Ostarine

This is an example of a MK 677 + Ostarine cycle. This is a great cycle, Ostarine is really well researched and will allow you to build muscle and lose fat. It has great synergy with a compound like Ibutamoren. Another great thing about this is that you won’t need a PCT (Post Cycle Therapy) for a cycle like this. Ostarine isn’t that suppressive, especially not at normal dosages like in this example, so you won’t need to do a PCT
