MK 677, also known as Nutrobal or Ibutamoren, is a powerful growth hormone secretagogue that is used by athletes to increase levels of HGH in the body.
It was originally created by Reverse Pharmacology to treat muscle wasting disorders such as osteoporosis. When clinical trials began, researchers noticed that MK677 drastically increases the amount of IGF-1 and HGH in humans. These increased levels result in added lean body mass along with fat reductions.
Many athletes have been adding Nutrobal into their regimens due to it’s ability to increase performance, help with recovery, and destroy body fat. In this article we will go through everything you need to know about MK 677, including benefits, side effects, dosages, before and after pictures, where to buy, and also an FAQ.
You will notice that there are a lot of clickable links in this article. We are dedicated to citing our sources and making sure we only promote factual material that is backed by science. Occasionally we will add and remove citations depending on the current perspective of the sports medicine and athletic community.
With all that being said, let’s jump right into it!
Benefits of Using MK 677
There are a ton of reasons why athletes use ibutamoren. Here are some of the top benefits of using nutrobal in your supplement regimen:
Decreased Muscle Catabolism
Nutrobal has been shown to decrease the amount of muscle lost during a cut. In this study, participants were given 25mg of MK-677 per day. By the end of one week, those taking the ibutamoren increased that levels of IGF-1 and HGH by a whopping 60%. The researchers also found that those taking the drug had a better level of nitrogen balance than those who didn’t take it. The conclusion of the study shows that MK677 is useful for treating humans who are in a catabolic state to reduce muscle loss.
Elevated levels of insulin like growth factor (IGF-1) and growth hormone lead to higher levels of fat loss. The same study we referenced above shows that at the end of 14 days, those taking MK677 lost a significantly more amount of fat than the control group. Athletes who take this compound will experience a faster rate of fat loss than normal.
It’s no secret that bodybuilders use HGH to gain insane amounts of muscle mass before they do a show. MK 677 is no different in this regard. By taking it, your body’s levels of HGH will be sky high, and you will pack on muscle faster than you could imagine.
Doesn’t Need to be Cycled
One of the best things about MK-677 is that it does not need to be cycled off and on. It does not suppress your body’s natural testosterone production and therefore it is not uncommon for people to never cycle off of this compound. There are a lot of accounts of people on the internet who run it for 6 months to a year at a time and have had no adverse side effects.
Reduced Recovery Time
By drastically elevating the amount of IGF-1 and HGH in your body, you will not need to take nearly as many rest days as you would naturally. In fact, many people who start using ibutamoren start training twice a day to take advantage of this benefit.
Better Sleep Patterns
One of the most important thing for anyone who is trying to gain muscle or lose fat is proper sleep. In fact, this study shows that not getting enough sleep can actually curb your weight loss and prevent you from achieving results. MK 677 helps your body reach a deeper sleep. While it does not make you fall asleep like a sleep aid will, it does make your sleep deeper and more resting.
Hair, Skin, and Nails
Last but not least, many people who take MK-677 report that their skin appears to glow, and their hair and nails seem healthier. This is because MK 677 increases collagen in the body which will help you look more youthful than normal. Many famous people have admitted to doing HGH to remain youthful – this compound allows you to get the same results.
Unlike steroids and other illegal anabolics, there are not very many side effects associated with MK 677 use. There are, however, some changes that can happen to your body due to elevated GH levels. These changes can be easily reversed by stopping usage. Here are some of the side effects of MK677:
When your body has high levels of HGH flowing through it, water retention can be a common reaction. The good news is that a lot of this water is held inside the muscles, similar to what creatine does. This is one of the ways that HGH can increase strength in athletes. With that being said, some water can be stored under the skin and therefore give a bloated appearance. We typically do not see water retention or bloating at doses of 25mg a day, so try to keep your dosage around that level.
You can also reduce bloating by taking a diuretic such as dandelion root extract.
While this is great for those who are on their winter bulk cycle, those who are trying to take advantage of MK 677’s anti catabolic effect might find this side effect annoying. There’s no way to deny it: ibutamoren will make you hungry. Luckily, this effect is temporary and typically curbs by itself in around 2 weeks. Because of this, we suggest starting your cycle 2 weeks before you start dieting in order to get the hunger out of the way first.
Numbness in Hands or Feet
If you start to feel “pins and needles” in your hands and feet, do not panic. This is not a dangerous side effect, and a quick google search will show you this is a common side effect of growth hormone. While nobody knows why this happens, doctors agree that it’s not dangerous and has nothing to do with damaged nerves.
MK 677 vs HGH
Many athletes use MK-677 as an alternative to HGH. If you’re wondering if it can replace HGH therapy completely, there are a few things you should consider. Here is how MK 677 stacks up vs HGH:
Injections vs Oral
HGH needs to be injected under the skin (but not into your vein), while nutrobal is taken orally. For many people, this is a deciding factor when deciding which route to go. Most everyone will prefer the ease of using an oral solution rather than injecting.
MK 677 needs to be taken orally once per day. HGH requires injections, and you need to inject frequently. In fact, many bodybuilders inject HGH up to 5 times per day!
Legitimate HGH is very expensive. With insurance, you can expect to pay $500 a month just in co pays, and without insurance you will be paying thousands of dollars per month for your prescription. MK 677 is a lot cheaper than HGH. The average cost of legitimate MK677 is between $50 to $100 a month.
What Results to Expect
Before you commit to jumping on the ibutamoren train, you should know what to expect. By being aware of the changes that will happen to your body, you’ll know right away that you’re taking the right compound and you’ll have better body awareness. Typically you can expect to:
- Gain muscle, especially in the arms and back.
- Lose fat
- Improve sleep quality
- Have better skin, hair, and nails.
- Feel younger and more rejuvenated.
Let’s go even deeper and tell you what to expect depending on what type of cycle you are running:
Bulking Cycle Results
Those who use MK 677 for bulking can easily expect to gain 10lbs over an eight week cycle. Some of this weight will be water. You can also expect to gain a decent amount of strength while on cycle as well. Most people have zero side effects, but you might notice some increased hunger and water retention.
We encourage you to follow a high protein diet, and do not be afraid of carbs (especially post workout). This will allow your Nutrobal to shine and give you the results that you want.
Cutting Cycle Results
Those who are using ibutamoren for a cut will see a very high level of muscle retention while losing fat. Fat will be lost at an accelerated rate, and a lot of people actually gain a few pounds of muscle along the way. Do not expect to gain a lot of muscle on a cut, but you can be sure that your strength will not decrease as well.
Cutting cycles should be accompanied with a very high protein diet. We suggest cutting simple carbohydrates such as white bread and sugar from your diet to help lean you out.
Before and After Pictures
We searched the internet and found some legitimate before and after pictures from people who used MK 677. As you can see from both photos below, this compound can drastically change how your body looks. Both guys lost a good amount of body fat but more importantly gained a ton of muscle.

Pure MK 677 For Sale
Finding pure MK677 for sale can be difficult if you don’t know where you should be looking. Luckily, we have reviewed over 20 different SARM suppliers to narrow down the best places to buy.
One thing we’ve found is that MK-677 is faked a lot more than some of the other SARMs and research chemicals. We believe that is because it is more expensive to manufacture than other compounds.
Our recommended source is Proven Peptides. We have batch tested their products and each results shows a very high level of purity (between 97% to 99% depending on the product).
Best MK 677 Dosage
Depending on where you look, people will recommend a dose of anywhere from 10mg to 100mg a day. Luckily, we have this study which actually compares HGH levels between doses.
What you see with the data is that there is a huge diminishing return with the higher doses. Once you go past 25mg per day, the amount of HGH and IGF-1 that enter the bloodstream gets lower and lower.
For that reason, the best dosage of MK-677 is 25mg per day. At this dose, you will get all the benefits of using ibutamoren but not put yourself at risk for any of the water retention side effects.
The half life of MK 677 is around 24 hours. You can dose once per day if you like, or you can split doses between morning and night. We prefer dosing twice a day (about 12 hours apart if possible) in order to spread out the concentrations evenly over each day. The less your levels are peaking, the better.
Capsules vs Pills vs Liquids vs Powders
There are a lot of different forms you can purchase nutrobal in, but which one is best? We are big fans of liquids for a lot of reasons. First of all, you get the most flexibility with how you dose. You can easily split your doses between AM and PM with no issues, or even split it into three and take one dose pre workout. You can not do that with capsules, pills, or powders.
Another reason why we like liquids are because they tend to be more accurate. Getting 10mg of powder exactly into a capsule or pill is extremely difficult if you don’t have the right machines (which most labs don’t invest in). Liquids are much more reliable in terms of accuracy.
MK 677 as a PCT
One of the best ways to use this compound is actually as a post cycle therapy after steroid use. Since it is not suppressive in any way, you can use it to help retain strength after a cycle of anabolics. Combined with low dose ostarine, you will be able to retain a lot more muscle mass than someone who didn’t use it.
Increasing your IGF-1 and HGH levels after a cycle is key to keeping gains, so ibutamoren will help you keep your results and prevent gaining of fat off cycle.
