MK-677 is also known as Nutrobal or Ibutamoren and is a powerful growth hormone secretagogue that increases levels of HGH (Human Growth Hormone) in the body.
It was originally created to treat muscle wasting disorders such as osteoporosis. When clinical trials began, researchers noticed that it drastically increases the amount of IGF-1 and HGH in humans.
As you may know, increased HGH and IGF-1 levels provide a whole host of benefits in athletic performance. In this article we will go through everything you need to know about MK 677, including benefits, side effects, dosages, before and after pictures and also an FAQ.
You will notice that there are a lot of clickable links in this article. We cite our sources and make 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
Decreased Muscle Catabolism
Ibutamoren 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 their 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 proves it to be useful for treating humans who are in a catabolic state.
Elevated levels of insulin like growth factor (IGF-1) and growth hormone lead to higher levels of fat loss (source). The same study we referenced above shows that at the end of 14 days, those taking MK-677 lost a significantly more amount of fat than the controlled 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.
For those looking for an alternative to HGH replacement therapy Ibutamoren shows promising results. Taking it before growth plates close will allow for increased height growth in males. This is an expected result, since MK-677 allows the body to produce much more HGH than it normally would.
Safe to Take Year Round
MK-677 does not need to be cycled on and off. 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 things 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 restfull.
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 MK-677:
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.
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 is no way to deny it that Ibutamoren will make you hungry. Luckily, this effect is temporary and typically curbs by itself in around 2 weeks.
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.
Whether or not MK-677 causes anxiety is currently up for debate, however the majority of experts agree that pharmacologically it should NOT cause anxiety.
There are not any studies that list anxiety as a side effect, and reports of it on the internet are few and far between. It is much more likely that anxiety experienced on cycle is entirely situational.
Differences Between MK-677 VS HGH
The main differences between MK-677 vs HGH are:
- MK 677 is taken orally, whereas HGH needs to be injected
- MK 677 is available for sale over the county, whereas HGH requires a prescription
- MK 677 can be taken once per day, whereas HGH requires multiple doses a day
Injections vs Oral
HGH needs to be injected under the skin (subcutaneously), while Ibutamoren is taken orally. For many people, this is a deciding factor when deciding which route to go. Mostly 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, and you will be paying thousands of dollars per month for it. MK-677 is a lot cheaper than HGH. The average cost of legitimate MK-677 is between $100 to $180 a month.
What Results Can You 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. You can expect the following results from using MK-677:
- Muscle gain, especially in the arms and back
- Improved sleep quality (REM and deep sleep)
- Clearer skin from an increase in collagen production
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 8 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.
It is best you to follow a high protein diet, and do not be afraid of carbs (especially post workout). This will allow your Ibutamoren 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. It is best to simply cut simple carbohydrates such as white bread and sugar from your diet to help lean you out, but still keeping carbs well under control.
Where to Buy
Finding pure MK-677 for sale can be difficult if you don’t know where you should be looking.
One thing we’ve found is that it 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.
MedLabsAU is one of Australia’s longest running and trusted sources to purchase 99% high quality SARMs from and has many verified customer reviews which you can view here.
What Dosage to Use
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 20mg / 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 20mg per day. At this dose, you will get all the benefits without putting yourself at risk for water retention and bloating side effects.
The half-life of MK-677 is around 24 hours. You can dose once per day at any time.
MK-677 During PCT
One of the best ways to use this compound is to include it with your Post Cycle Therapy protocol. Since it is not suppressive in any way, you can use it to help retain strength after a cycle of SARMs.
Another option is to combine it with low dose Ostarine. This is only recommended if you’re coming off a heavy-duty steroid cycle and are at risk of losing a lot of muscle. By using this combo, you’ll be able to keep a lot more of your gains than you would be able to naturally.
Typical PCT stacks usually contain either Clomid or Nolvadex. These SERMs are great at stimulating natural testosterone levels but will also lower your IGF-1 production. Adding in a growth hormone secretagogue such as this one will counter act some of those negative effects.
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.
Frequently Asked Questions
How long does it take to kick in?
Serum HGH and IGF-1 levels increase rapidly once you begin your cycle. Peak levels are achieved after around 30 days depending on your body composition. Most people notice a better night’s sleep immediately along with increased strength and recovery becoming apparent after the first week.
Is MK-677 safe for women?
Yes, it is. MK-677 lacks any sort of androgenic effect, women can take it without issues. There is no vitalization potential in any way.
Can MK-677 cause gyno?
Absolutely not. Like mentioned above, this compound is not androgenic in any way. It will not affect levels of testosterone, estrogen, or DHT, therefore gynecomastia is not a concern with this compound.
In conclusion, MK-677 proves to be a useful tool for anyone who wants to increase their HGH and IGF-1 levels. This compound is going to have a big impact on people who cannot afford to use prescription grade HGH, especially those with growth hormone deficiencies.
If you’re looking for a relatively safe and easy way to reap the benefits of HGH without injecting, this is your best bet.
