As its name suggests, Ibutamoren is a non-peptide drug that boosts growth hormone production by stimulating the pituitary gland. 

Ibutamoren does not work like anabolic steroids, which affect the body's androgen receptors. Instead, it targets different receptors that control growth hormone secretion and metabolic processes.

Since MK-677 does not affect testosterone secretion, your body is not subject to hormonal disruptions and other unpleasant consequences, as with steroid hormones. Therefore, there's no need for post-cycle therapy.

What Exactly Is Ibutamoren / Nutrobal (Mk-677)?

Ibutamoren, also known as Nutrobal and MK-677, is a selective agonist of the ghrelin receptor and growth hormone secretagogue. As a result, it effectively increases insulin-like growth factor 1 (IGF-1) and growth hormone secretion.

Nutrobal was initially developed to treat health conditions such as osteoporosis, muscle wasting, and obesity. This orally administered growth hormone secretagogue is also indicated for treating elderly patients with hip fractures. 

Action Mechanism Of Ibutamoren

Nutrobal works by improving the release of GHRH (growth hormone-releasing hormone). As its name suggests, this is not a growth hormone (GH) but another hormone that releases it.

Ibutamoren also inhibits the signaling of the somatostatin receptor. In addition, it amplifies the signalling of GHRH in somatotrophs of the anterior pituitary gland. Nutrobal is instrumental in minimising the release of somatostatin, a substance that turns off the release of growth hormones in the body. 

Research shows that Nutrobal, or Ibutamoren, can improve the level of growth hormones in the body. It does this by mimicking the action of ghrelin, a hormone that promotes hunger and stimulates metabolism. 

MK-677 binds to GHSR, one of the androgen receptors in the brain. It is worth noting that activated GHSR stimulates growth hormone release from the brain. 

By doing this, Nutrobal also improves several factors, including:

  • Appetite;
  • Biological rhythms;
  • Memory;
  • Cognition;
  • Mood;
  • Pleasure and sense of well-being.

One of the bonuses of Nutrobal is that it improves the levels of growth hormones with little to no increase in the levels of other hormones like cortisol. 

Other possible advantages can include: improved complexion, increased energy levels and strength, increased endurance, protein synthesis, and nitrogen retention. 

Nitrogen is a fundamental component of amino acids responsible for forming proteins. Therefore, when the body is in a positive nitrogen balance, it has the material to repair injuries and produce the required levels of hormones. 

Several studies have also suggested that MK-677 stimulates an increased immune system response. 

One more noteworthy characteristic of MK-677 is that it does not at all compete with the levels of growth hormone that are usually associated with the administration of exogenously administered human growth hormone. As a result, you can use Nutrobal for HGH cycles, offering an increase in natural GH pulses. It also means you don't have to deal with painful or annoying daily human growth hormone injections. 

All these advantages suggest that athletes, bodybuilders, and others can use Nutrobal for various purposes. There are many benefits, from growing muscle mass to getting shredded. 

Mk-677 Benefits

The main benefits of MK-677 are an increase in growth hormone and IGF-1 levels. Growth hormone helps with tissue repair, muscle growth, and fat loss. IGF-1 is essential for cell growth and regeneration.

Improves Muscle Building

Ibutamoren is highly effective in stimulating a dramatic increase in levels of lean body mass. It also shows similar efficacy for increasing muscle mass, muscle strength, and muscle definition while reducing body fat.

Minimises Muscle Wasting

Ibutamoren is an excellent drug for reversing diet-induced weight loss that can happen with muscle wasting. Furthermore, Nutrobal can considerably improve gait speed and muscle strength. It can also minimise the number of falls in elderly patients with hip fractures. 

Enhances Sleep Quality

Scientific studies have demonstrated that Ibutamoren can positively influence REM sleep duration and overall sleep quality. In the same way as ghrelin, it keeps the circadian rhythm in check and promotes consistent and uninterrupted sleep. As a result, those taking Ibutamoren often might find that they can sleep more soundly and feel refreshed after waking up.

Improves Longevity 

Ibutamoren can improve the levels of IGF-1 and growth hormone in the body, which has several benefits. A lack of IGF-1 is present in those with growth hormone disorders and can lead to brittle bones, low muscle mass, and altered lipid levels. It's suitable for people experiencing a decline in muscle mass and GH secretion. Even those with average levels can profit from some of Ibutamoren's benefits. 

Improves Bone Density 

Healthy bones are essential, regardless of age, weight, or athletic capabilities. Brittle, weak, or porous bones can lead to injuries from seemingly minor accidents and, as well as being painful and slowing down your sports progress, can be a precursor to issues like osteoporosis. Growth hormone is highly effective in increasing bone turnover and eventually density of the bones. 

In a study of older women with existing osteoporosis, Emily Krantz, MD, reported that: “Years after treatment stopped, women who were treated with growth hormone still experienced improved bone density and reduced fracture risk.” 

Nootropic Effects 

Nutrobal acts in the ghrelin receptor that is well known to have nootropic effects. They positively impact brain function in motivation, memory, and creativity. The fact that Nutrobal also improves sleep quality and duration also helps; this is because both of them are critical for enhanced cognitive functioning. 

Treating Growth Hormone Deficiency 

MK-677 improves IGF-1 and growth hormone levels in children with GH deficiency. It also treats Insulin-like Growth Factor binding protein 3 (IGFBP-3) in these children. These benefits happen without adverse effects on thyrotropin, prolactin, and glucose.

Accelerates Skin Healing 

Another MK-677 benefit you might experience is more rapid healing after surgery or a wound. Nutrobal shows excellent promise to heal old and nagging injuries. It also helps tighten loose skin besides healing tendons, bones, and ligaments and is equally effective for healing wounds and regenerating tissue. 

The increase in collagen is responsible for this, and MK-677 might be worth considering if you find your recovery time slowing down as you age. Buy SARMs for sale now and feel the difference for yourself!

Improves Shredding 

A lot of potential MK-677 users are worried about how a product that increases ghrelin (the “hunger hormone”) can help when they want to stay in a calorie deficit. 

An underrated powerhouse, ghrelin, boosts hunger and helps you consume more calories. At the same time, it plays a critical role in the regulation of energy use (stored fat). 

When chosen safely and in line with your doctor’s advice, there is nothing wrong with adding other compounds to combat these effects and help you limit hunger cravings. Read our post on stacking to learn more about safely combining supplements for multiple effects. 

However, Nutrobal’s muscle-building properties do help you retain your hard-earned gains, even on a calorie deficit. 

Reduces Effects Of Nitrogen Wasting 

The final Ibuatmoren benefit is that it can contribute towards reversing nitrogen wasting in the body. 

Nitrogen wasting occurs when a person's nitrogen excretion exceeds the amount they take in and causes a catabolic state in the body. This will lead to fat and muscle loss over time and is not ideal for those looking to bulk! Ibutamoren restores the nitrogen balance in those with low levels and keeps it in equilibrium. 

Mk-677 Side Effects

Prolactin Effects

Ibutamoren may increase prolactin levels. Prolactin is a hormone involved in milk production and regulating the immune system. In a study on rats, Ibutamoren increased prolactin levels after 14 days of treatment. 

Gastrointestinal Effects

Ibutamoren may cause gastrointestinal side effects such as diarrhoea, nausea, and vomiting. In a study on rats, Ibutamoren caused gastrointestinal side effects after 14 days of treatment. However, it is unclear if Ibutamoren has the same product in humans.

Hormone Regulation

Ibutamoren may alter hormone levels. In a study on rats, Ibutamoren increased growth hormone, IGF-1, and prolactin levels after 14 days of treatment. It is still being determined if Ibutamoren has the same effect in humans. Ibutamoren is generally well-tolerated, but long-term safety data are lacking. There are no known severe side effects associated with Ibutamoren use.

Hypo-Pituitary Desensitisation

Ibutamoren may cause hypo-pituitary desensitisation. This is when the pituitary gland becomes less sensitive to growth hormones. In a study on rats, Ibutamoren caused hypo-pituitary desensitisation after 14 days of treatment. However, it is still being determined if Ibutamoren has the same effect in humans.

Nutrobal Half-Life

The half-life of Nutrobal is about 4 to 6 hours. Therefore, experts recommend a twice-daily dosage of Nutrobal. Male users can take two equal split doses of 12.5mg once in the morning and again in the evening. Female users can take between 2.5 and 7.5mg, once in the morning and once in the evening.

Nutrobal is best stacked with SARMs like Ostarine (MK-2866), Andarine (S-4), LGD-4033, and Cardarine (GW-501516). It is best in a cutting stack cycle with Ostarine, S-4, and Cardarine. It may also be stacked with Ligandrol for muscle mass gains. For the cutting cycle, Nutrobal can be stacked at two split doses of 12.5mg every day. Men should use 20mg Cardarine every day with it for 10-14 weeks. Always check and follow the guidelines in your area as laws on these supplements differ. 

It is always recommended to go safe with post cycle therapy. For this, consider the use of Bodybuilt Labs SARMs Cycle Support 90 Capsules for cycle support. The use of Bodybuilt Labs SARMs PCT 90 Capsules for Post Cycle Therapy is also suggested. Buy SARMs for sale now.

How To Use Ibutamoren

Nutrobal is clinically proven to be effective and harmless. It gives the best results with little to no side effects. The best time to take MK-677 is before bedtime.

You do not need to limit admission to cycles, but if you have concerns, the recommended course duration is 12 weeks in 6-week intervals at most. The drug is suitable for both mass gain and fat burning.

Mk-677 Dosage

According to experts, the optimal dosage is 20 to 30 mg. Exceeding the dosage over 30 mg does not give a pronounced additional effect.

When taking Ibutamoren, the course's duration is more important than the daily dosage. Therefore, the use of MK-677 must be long-term. Growth hormone levels rise gradually over at least several weeks. 

Professional bodybuilders recommend taking Ibutamoren in the following daily dosages, depending on the task at hand:

  • Increased muscle growth - 30 mg.
  • Fat burning - 20 mg.
  • Healing injuries and recovery - from 10 to 20 mg.
  • For beginners without experience with SARMs or other drugs, starting with a minimum dosage of 10 mg is recommended, regardless of goals.

Precautions To Take

It is important to note here that Nutrobal is not advised for use amongst pregnant or breastfeeding women, and should not be used by children and/or those below the age of 21 years. Those who have an allergy to the substance’s active or inactive ingredients should also avoid using Nutrobal. The use of this GH secretagogue should always be made only after a medical recommendation. 

Remember that dosages of this potent performance-enhancing drug should never be altered without prior medical recommendation. Under no circumstance should you increase your dosage without medical recommendation as that may lead to overdosing or abuse.

Mk-677 Vs. Hgh

MK-677 is a long-acting growth hormone secretagogue that you should take orally. It imitates the growth seen in GH. Consuming MK-677 daily has the potential to raise GH and IGF1 levels significantly in healthy young adults without causing significant adverse side effects. 

Human Growth Hormone, also known as Somatropin in its full form, is a hormone that encourages growth among all human body tissues. This includes bone regeneration and cell reproduction. HGH is essential for keeping the tissues in our brain and other organs healthy.
