What is MK-677?
MK-677 (popular as Ibutamoren) is an orally active growth hormone secretagogue. It works by mimicking the effects of the endogenous hormone ghrelin, stimulating the action of growth hormone (GH) release. This is a powerful, long-lasting, and selective non-peptide agonist of the ghrelin receptor. Thanks to this, MK-677 (Ibutamoren) has been proven to increase the secretion of human growth hormone (HGH) as well as insulin-like growth factor 1 (IGF-1). It manages to sustain an increased plasma level of these hormones. Still, it remains an investigational new drug (a research chemical) without FDA approval for any medical uses. Instead, MK677 (Ibutamoren) already become very popular for physique and performance enhancement purposes in bodybuilding settings. It has been proven to have effects on lean mass, fat, sleep, appetite, and performance. Ibutamoren is often categorized as a SARM due to its selective part. It doesn’t bind to androgen receptors though.
Is MK-677 a SARM?
No, MK-677 (Ibutamoren) is not a SARM (Selective Androgen Receptor Modulator) because it does not bind to androgen receptors. Yet, it is often associated with SARMs because of its popularity in similar circles and because it also works in selective manners as SARMs. However, instead of selectively binding to androgen receptors, it selectively binds to ghrelin receptors, mimicking the action of the hunger hormone ghrelin. This is how MK677 manages to stimulate a higher release of human growth hormone (HGH). Moreover, similar to SARMs, it is also popular in bodybuilding settings for its ability to enhance physique and performance. Due to these reasons, MK-677 (Ibutamoren) is often associated and/or categorized as a SARM, but it is not a SARM itself. It is rather a growth hormone secretagogue.
Is MK-677 a steroid?
No, MK-677 is in no way or form a steroid. In fact, despite it being often associated with SARMs, MK-677 (popular as Ibutamoren) is not even a SARM. This compound is actually a growth hormone secretagogue, a drug that will stimulate the production of growth hormone. So, no, MK-677 is not an anabolic steroid. It is so far a research drug, but bodybuilders and athletes still use it for physique and performance enhancement goals with a high success rate. MK677 manages to increase levels of IGF-1 and HGH, which comes with numerous benefits such as muscle growth, fat loss, sleep quality increase, increase in bone mineral density, boost in performance, especially stamina, energy, and endurance as well as other results.
What are dosages for MK-677?
There is no official guideline about MK-677 (Ibutamoren) dosage because this compound is not yet approved by the FDA for medical purposes. Instead, MK677 went through various clinical tests on humans and it is also popular among athletes and bodybuilders using it for physique and performance enhancement purposes. It seems that dosage varies from 5 mg up to 50 mg a day, with the most common doses being between 10 mg to 25 mg a day. I would recommend starting with a lower dosage of 5-15 mg a day for beginners and increasing the dosage up to 25 mg a day during the first cycle if necessary, no sooner than 4 weeks into the lower dosage. Most people suggest that 25 mg a day of MK-677 is enough.
What does MK-677 do?
MK-677 will selectively bind to ghrelin receptors, mimicking the activity of the hunger hormone ghrelin, which leads to a higher release of human growth hormone (HGH) and insulin-like growth factor 1 (IGF-1). Being a growth hormone secretagogue, it will provide all the benefits associated with higher HGH levels. Some benefits of higher HGH levels are muscle growth enhancement, boost of metabolism, improved bone density, better sexual health, fat loss, better performance, higher energy, stamina, endurance levels, and many others. Benefits for general health improved physical performance, and better body image (physique). Generally, the benefits of higher HGH levels. So, MK-677 (Ibutamoren) mimics the action of ghrelin, which basically means that MK677 helps secrete more HGH levels.
Is MK-677 for bulking or cutting?
MK-677 (Ibutamoren) is an HGH secretagogue, meaning that it will increase growth hormone (and IGF-1) levels. These hormones are actually extremely important for both bulking and cutting cycles. HGH, for example, manages to boost muscle growth for bulking goals, but it also helps burn fat (especially around midsection) for cutting. It also manages to boost energy and stamina, and reduce recovery time which is important for both cycles, especially in cutting cycles because you eat less, meaning that recovery time, energy, and stamina could be a problem. Therefore, you could use MK-677 for both bulking and cutting cycles, depending on your training and diet. Nevertheless, most people still use it for bulking goals. This is mainly because many report an increase in hunger while using Ibutamoren. An appetite boost may be beneficial for bulking and detrimental for cutting.
How to take MK 677?
MK-677 is a potent and orally active non-peptide agonist of the ghrelin receptor. Being orally active means that MK-677 can be taken orally (by mouth, swallowing) as a powder, tablet, or liquid. Peptides usually need to be injected, but Ibutamoren is a non-peptide agonist of the ghrelin receptor which works as a growth hormone secretagogue. While the effects of MK677 are similar to peptides that increase HGH levels, it is not a peptide itself, meaning that you can take it orally. Usually, it is taken once a day, at around the same time of the day, every day throughout the cycle. More commonly than not, Ibutamoren is taken before going to sleep on an empty stomach. The dosage depends on various factors such as goals, personal response to it, experience, and so on.
Is MK-677 safe?
MK677 is not yet FDA-approved as it is still a research compound. Nonetheless, preliminary clinical tests conducted on human subjects suggest that MK-677 is safe. The same thing is proven by anecdotal reports from people who use it for their physique and performance enhancement goals. While it does come with some health risks, especially if abused or misused, most users experience no or tolerable side effects, making it a safe compound. Pretty much the only common side effect of Ibutamoren is increased appetite. That is something to expect as it mimics the effects of the hunger hormone ghrelin. Other side effects could be associated with those of higher HGH levels maintained for long cycle lengths such as an increase in blood glucose levels, reductions in insulin sensitivity, and increases in glycated hemoglobin. These are risks that are usually in those who use MK677 (Ibutamoren) for long periods in larger doses.
When to take MK-677?
MK-677 (Ibutamoren) is taken once a day, at the same time each day, every day during the cycle, preferably on an empty stomach as this will keep stable and higher levels of HGH in your bloodstream. Considering that MK-677 helps boost the secretion of HGH levels and the natural growth hormone pulse secretion mostly occurs at night, MK-677 seems to be best taken at night, before going to sleep. That’s especially true considering that Ibutamoren may increase appetite. You could avoid this issue if you take it before going to bed. Yet, those who do want an increase in appetite may use it in the morning.

How long is MK-677 detectable in urine?
Ibutamoren (MK677) is a drug that remains detectable in blood samples and urine tests. The exact detection time is unknown. However, the detection time may vary depending on the dosage, duration of use, as well as your metabolism. It is believed that MK-677 can be detected in urine for up to several weeks. If you are about to have an anti-doping test, I would recommend staying away from its use for at least one month before the test. A standard drug screen will not look for Ibutamoren (MK677), only anti-doping tests (in professional sports) look for it.
How much MK-677 should I take?
MK-677, popular as Ibutamoren, is a growth hormone secretagogue that manages to boost HGH levels by mimicking the effects of the hormone ghrelin. Using low doses will not release as much HGH while using too large doses can come with side effects (especially associated with water retention, an increase in appetite, and too high HGH levels). Common dosage is 25 mg a day. While larger dosages are not unheard of, they increase the risks of side effects. Lower doses are common for beginners, starting at around 5-15 mg a day. You could start with the lower end of 5-15 mg a day, then slowly and gradually increase to 25 mg a day if necessary. Rarely does someone need larger doses. Usually taken once a day, at the same time of the day (usually at night, but could be used in the morning too), during the entire cycle length.
Can MK-677 make you taller?
Studies suggest that MK-677 increases your HGH levels. At the same time, studies suggest that higher HGH levels can increase your height. Nonetheless, that’s all true only as long as your growth plates have not fused (closed), which happens anywhere between 13 to 17 years for most people (adolescents). Using Ibutamoren (MK677) after your growth plates have closed will not help increase your height. In fact, nothing will make you taller if the growth plates have closed.
How to take liquid MK-677?
MK677 – Ibutamoren usually comes in the form of tablets that you can simply consume with a glass of water as any other pill. However, sometimes, liquid MK-677 is also available. Unlike capsules, tablets, or powders, liquid MK-677 is taken by placing drops under your tongue. You can use an eye dropper or syringe. This will lead to quick absorption into the bloodstream. But you can still swallow the liquid or use it with water.
Does MK-677 increase testosterone?
No, MK-677 Ibutamoren will not affect your testosterone levels as it is not a steroid or a SARM. It is an HGH secretagogue that will increase your natural growth hormone production. It may affect other hormones such as IGF-1 (Insulin-like growth factor 1) and cortisol. Nonetheless, it will not affect (decrease or increase) sex hormones. Such as testosterone, luteinizing hormone (LH), follicle-stimulating hormone (FSH), and sex hormone binding globulin (SHBG). Still, an increase in HGH levels could be beneficial in boosting natural testosterone production. But only for people suffering from hypogonadism (such as in men with low testosterone due to the use of suppressive steroids). Yet, the effects are minimal, so low that HGH is not an effective treatment for low testosterone. Still, some use MK-677 to boost HGH levels during PCT to help increase testosterone production a bit.
Does MK-677 work?
Yes, the use of MK-677 (Ibutamoren) does work very well for most people. According to studies and anecdotal reports, MK677 manages to increase REM sleep. According to studies, an average of 20% more in young subjects, and an average of 50% more in older subjects. It also helps increase deep sleep. Studies prove that MK-677 also manages to boost HGH levels efficiently, meaning that it does work great for most people. This compound will work great for most users as long as it is used correctly. It does work, but it needs an adequate diet and training plan (with a proper dosage) for it to work the best way when it comes to physique and performance enhancement goals.
How long does MK 677 stay in your system?
The elimination half-life of MK-677 is only 4-6 hours. Nonetheless, the IGF-1 levels remain high in humans with a single oral dose for up to 24 hours. This is the reason why it must be taken every day. It will be out of the system in about a maximum of two days. Nonetheless, it is important to understand that it may be detectable in your system for longer if talking about anti-doping tests. The detection window can vary depending on dosage, duration of use, and metabolism. It could remain detectable in your system for several weeks.
