What Is Ibutamoren MK-677
Ibutamoren, known by its pharmaceutical name MK-677, is a potent, long lasting, orally active, selective, non-peptide agonist, of the ghrelin receptor and a growth hormone secretagogue. Ibutamoren, aka MK-677 is one of many investigational new compounds, that is being tested for several different indications, yet is most commonly known for its off label use a performance enhancing drug. Ibutamoren is an agonist of the ghrelin receptor and a growth hormone secretagogue. Ibutamoren mimics the actions of growth hormone releasing peptide-6 to increase serum levels of serum insulin-like growth factor-I (IGF-I) Ibutamoren, is unique as a dual agonist, yet it is not a traditional peptide. Ibutamoren, mimics the action growth hormone and has been shown to increase the secretion of several hormones including insulin-like growth factor-I (IGF-I). Ibutamoren increases plasma levels of hormones, without affecting cortisol levels.
Ibutamoren, is currently being developed by pharmaceutical giant Merck & Co for a variety of indications, including muscle wasting, fibromyalgia, chronic kidney disease, and growth hormone deficiency.
How Does Ibutamoren Work, What Does Ibutamoren Do
How MK-677 Works: The Science Behind It
MK-677, also known as Ibutamoren, is a non-peptide growth hormone secretagogue that mimics the action of the hormone ghrelin, which is known for its role in regulating appetite and growth hormone secretion.
By binding to ghrelin receptors in the brain, MK-677 stimulates the release of growth hormone (GH) and insulin-like growth factor 1 (IGF-1) without affecting cortisol levels. This unique mechanism of action allows MK-677 to promote increased GH levels, which are crucial for muscle growth, fat metabolism, and overall physical development.
One of the most fascinating aspects of MK-677 is its ability to elevate GH and IGF-1 levels for extended periods. Unlike other GH secretagogues that require frequent dosing, MK-677 can maintain elevated hormone levels for up to 24 hours with a single dose. This prolonged effect is due to its long half-life, making it a convenient option for those looking to optimize their hormone levels without the hassle of multiple daily doses.
Moreover, MK-677's impact on ghrelin receptors goes beyond GH secretion. Ghrelin is known to play a role in neuroprotection, cognitive function, and even mood regulation. By mimicking ghrelin, MK-677 may offer additional benefits such as improved sleep quality and enhanced cognitive performance, which can further support your muscle-building and overall fitness goals.
Ibutamoren is one of the most fascinating new pharmaceuticals currently under investigation. Chemically, MK-677 mimics the hunger hormone ghrelin, and functions as a neuropeptide in the central nervous system and crosses the blood-brain barrier.
How Do Secretagogues Work?
Growth hormone secretagogues facilitate the release of hormones. Hormone optimization has numerous health benefits including but not limited to improving body composition, increasing muscle mass, promoting fat loss, improving sleep parameters, supporting gut health, stimulating libido, and promoting joint health. Other forms of peptides may help and benefit brain health, and skin health.
Secretagogues are agents or peptides that promote the secretion and release of hormones, neurohormones, chemical neurotransmitters, enzymes, or other molecules synthesized and secreted by cells.
Growth hormone secretagogues (GHS) are synthetic, non-natural peptidyl and non-peptidyl molecules. GHS help facilitate the natural release of hormones such as human growth hormone and IGF-1, insulin-like growth factor, which is a hormone that manages the effects of human growth hormone.
MK-677 is a synthetic nonpeptidyl GHS, that has shown to work directly by mimicking the growth hormone secretion action of ghrelin.
Studies have shown that MK-677 sustains increased pulsatile GH and IGF-1 secretion to levels seen in young adults. The likely mechanism is activation of the ghrelin receptor by MK-677, with feedback by IGF-I preventing excess GH production.
Key Benefits and Risks of MK-677 for Muscle Growth
Key Benefits of MK-677 for Muscle Growth
1. Promotes Muscle Hypertrophy and Strength Gains
The primary allure of MK-677 for athletes and bodybuilders lies in its potent anabolic effects. By significantly increasing GH and IGF-1 levels, MK-677 promotes muscle hypertrophy, leading to greater muscle mass and strength gains. Users often report noticeable improvements in muscle density and a more defined physique, making MK-677 a valuable tool for those looking to maximize their muscle-building potential
(source).
2. Enhances Recovery and Reduces Muscle Soreness
In addition to muscle growth, MK-677 also enhances recovery times between workouts. Growth hormone plays a critical role in tissue repair and regeneration, meaning elevated GH levels can expedite the healing process and reduce muscle soreness. This allows athletes to train harder and more frequently, ultimately leading to better performance and faster progress
(source).
3. Supports Fat Loss Through Increased Lipolysis
Another significant benefit of MK-677 is its impact on fat metabolism. Increased GH levels boost lipolysis, the process by which the body breaks down stored fat for energy. As a result, users often experience a reduction in body fat percentage, particularly in stubborn areas such as the abdomen. This dual effect of muscle gain and fat loss makes MK-677 an attractive option for those aiming to achieve a lean, muscular physique
(source).
Studies have found, that MK-677 may be a therapeutic agent to help increase muscle mass. A decrease in circulating plasma levels of growth hormone, especially as you age, have been directly correlated with an increase in body fat and loss of lean body mass. Growth hormone is a lipolytic and acts to reduce and redistribute body fat, as well as increase protein synthesis [R].
A study investigating the effects of MK-677 on body composition in older adults, administered 25mg of MK-677 to 65 study participants for 12 months.
The results found, that with MK-677 orally administered, increased fat free mass after 12 months. Fat-free mass accounts for all your body parts that do not contain fat, including organs, bones, tendons, ligaments, muscles, blood, connective tissues, and nerves.
However, it is important to note, that the concomitant increase in intracellular water, which reflects body cell mass (R), is the likely mechanism for the increase in FFM [R].
Growth Hormone reduces abdominal visceral fat (AVF) in GH-deficient adults [R] and abdominally obese, postmenopausal women [R], but not normal elderly subjects [R]. Despite increasing GH levels, MK-677 did not affect AVF.
4. Better Sleep
GH induces several mechanisms for better sleep. The somatotropic axis consisting of growth hormone (GH), insulin-like growth factors (IGF-I and -II), and their associated carrier proteins are intricately involved in normal sleep, as evidenced by the fact that hypothalamic growth hormone-releasing hormone (GHRH) has sleep promoting effects and pituitary growth hormone (GH) release is strongly associated with slow-wave sleep (SWS) [R].
A small study from 1997, published in the journal Nueuroendocrinology researchers found that study participants with high-dose MK-677 treatment resulted in an approximately 50% increase in the duration of stage IV sleep and in a more than 20% increase in REM sleep as compared to placebo [R].
Potential Risks and Side Effects of MK-677
1. Increased Appetite
One of the most commonly reported side effects is increased appetite, which is a direct result of its ghrelin-mimicking action. Although this can be beneficial for individuals looking to bulk up, it may pose a challenge for those trying to maintain a strict diet or manage their calorie intake
(source).
2. Water Retention and Bloating
Water retention is another side effect that some users may experience. Elevated GH levels can lead to increased sodium retention and fluid accumulation, resulting in temporary weight gain and bloating. While this is usually a mild and reversible issue, it can be uncomfortable for some individuals and may affect their overall appearance
(source).
3. Potential for Insulin Resistance
More serious side effects, although rare, include insulin resistance and elevated blood sugar levels. Growth hormone can influence glucose metabolism, and prolonged use of MK-677 may potentially disrupt insulin sensitivity. It is important for users to monitor their blood sugar levels and consult with a healthcare professional if they have pre-existing conditions such as diabetes or metabolic syndrome
(source).
Recommended Dosage and Usage Guidelines

When it comes to dosing MK-677, it is essential to start with a conservative approach to assess individual tolerance and minimize potential side effects. A common starting dose for most users is 10–20 mg per day. This dosage is typically effective for promoting muscle growth, improving recovery, and enhancing overall physical performance
(source).
As users become more accustomed to the compound, the dose can be gradually increased to 25–30 mg per day if needed.
2. Best Time to Take MK-677
MK-677 is best taken in the evening or before bedtime. This timing aligns with the body's natural GH release cycle, which occurs during deep sleep. Taking MK-677 at night can also help mitigate the increased appetite side effect, as users are less likely to consume excess calories while sleeping. Additionally, some users find that taking MK-677 before bed improves sleep quality, further supporting recovery and muscle growth
(source).
3. Cycling MK-677
It is important to note that MK-677 is typically used in cycles to prevent potential long-term side effects and maintain the body's natural hormone balance. A common cycle length is 8–12 weeks, followed by a break of 4–6 weeks.
This cycling approach allows the body to reset and ensures that the benefits of MK-677 are sustained over time. As with any supplement, it is crucial to consult with a healthcare professional before starting a cycle to ensure it is appropriate for your individual needs and health status
