What is MK-677 Ibutamoren?

The compound MK-677, also known as Ibutamoren mesylate, stimulates the growth hormone (GH) flow and boosts insulin-like growth factor 1 (IGF-1). Ibutamoren increases growth hormone levels by mirroring the response of ghrelin, the hunger hormone, and attaching it to one of the brain’s growth hormone secretagogue receptors (GHSR).

Ghrelin is primarily found in the digestive system. It sends the message to the brain when you’re hungry, alerting the body when it’s ready to consume food. When Ibutamoren is taken, it imitates ghrelin, activating the feeling of “craving” in several aspects. As the Ibutamoren emits throughout the body, it triggers your appetite, pleasure, mood, memory, and awareness.

MK-677 Ibutamoren is neither an anabolic steroid nor a selective androgen receptor modulator (SARM). As a stimulant, it is commonly used by athletes, bodybuilders, and weightlifters for rapid muscle growth and improved performance.

What Does MK-677 Do?

MK-677 Ibutamoren is an oral peptide that increases muscle mass and speeds muscle growth. When taken daily, ibutamoren has been shown to improve sleep quality, skin elasticity, mental clarity, body composition, and recovery from exercise.

MK-677 Ibutamoren peptide therapy is a safer alternative than testosterone replacement therapy (TRT), also known as growth hormone therapy. When MK-677 Ibutamoren is taken as recommended, it only slightly triggers the body, generating more growth hormone (GH) and insulin-like growth factor 1 (IGF-1) at a safe level.

Growth hormone therapy through injections can be strenuous as well as dangerous. Injectable growth hormones raise GH and IGF-1 far above normal levels, which affects the body’s natural function. Injectable hormone therapy often produces negative results and dangerous side effects. The faults of HGH therapy are another reason why MK-677 Ibutamoren is the safer option to get similar results while treating growth hormone deficiency.

What Are the Benefits of MK-677?

MK-677 has become very attractive to those who live an active lifestyle–specifically in the gym. The benefits, however, do step outside the barriers of someone looking to improve their muscle and body mass. Some of the benefits of MK-677 (Ibutamoren) include the following:

Increased Muscle Growth

MK-677 Ibutamoren is known for stimulating rapid muscle growth and increased muscle mass. While everyone’s body mass and exercise routine differ, some might see more results and changes in their body than others. Bodybuilders and weightlifters are more likely to consume MK-677 to improve their performance and overall physique.

Improved Bone Density

A study showed that growth hormone (GH) increases bone turnover and stimulates osteoblast activity. “The administration of MK-677, an orally active GH secretagogue, together with alendronate, a potent inhibitor of bone resorption, would maintain a higher bone formation rate relative to that seen with alendronate alone, thereby generating greater enhancement of bone mineral density (BMD) in women with postmenopausal osteoporosis.”

Muscle Loss Prevention

Bodybuilders and weightlifters often experience and struggle with muscle loss at some point in time on their fitness journey. When taking MK-677 Ibutamoren, this is not something to worry about. MK-677 increased muscle growth while preventing muscle loss in the process.

Increased Energy and Endurance

MK-677 Ibutamoren has been recorded to have increased physical performance and endurance through exercise. This boost of energy makes for a more efficient and dynamic workout.

Improved Sleep

Research shows that growth hormone (GH) and MK-677 Ibutamoren improve the quality and duration of sleep and rapid eye movement (REM) sleep and alter the relative growth hormone deficiency of senescence.

Improved Collagen

While many anabolic steroids and SARMs provoke skin problems and hair loss, MK-677 does the opposite. Studies have shown that Ibutamoren has improved hair and skin health and healed skin wounds and marks. Growth hormone (GH) boosts cell transformation and production, along with collagen management.

Increased Libido

As MK-677 Ibutamoren boosts the flow of GH and IGF-1, it also has the potential to increase testosterone levels, improving sex drive and erectile dysfunction. Taking MK-677 Ibutamoren daily could potentially enhance it through GH enhancement for someone struggling with low libido levels.

Is MK-677 Safe?

While MK-677 is considered similar to a SARM, according to research, it does not share any dangerous effects that most SARMs have. The side effects of SARMs include nausea, mood swings, testosterone repression, loss of libido, and liver intoxication. MK-677 is a safe alternative to receive the positive results of SARMs—improve muscle mass and bone density and increase strength and endurance.

The perquisites of taking MK-677 supplements daily have overruled its reputation as being a “dangerous” SARM. While it is one of the most well-known products for muscle growth, Ibutamoren is not commonly sold.

MK-677 is legal, although it is still labeled as an “Investigational New Drug” by the Food and Drug Administration (FDA). It is typically sold only for research purposes and cannot be labeled as a supplement. The World Anti-Doping Agency (WADA) has banned MK-677 from most, if not all, significant sports—especially the Olympics.

Side Effects of MK-677 Ibutamoren

The side effects of MK-677 may include:

• Muscle pain
• Joint pain
• Severe migraines and headaches
• Lack of energy
• Increased appetite
• Motivation loss
• Fluid retention
• Depression
• Increased stress and anxiety

The adverse side effects of MK-677 typically occur when the oral peptide is misused. Taking any substance or supplement in excess will more than likely result in an undesirable outcome. MK-677 Ibutamoren is advised to be taken orally once a day for optimal and safe results. If you have any pre-existing medical conditions or health concerns, consult a health professional before taking MK-677 Ibutamoren.
