The human hormonal and chemical system, known as the endocrine system, is still a mystery today. While it is incredibly complex, its function is straightforward - keeping the body healthy and moving forward. Everything from the happiness you feel, the muscles you build, the synapses that move your legs, and even eating, needs to be in tune with these signals. This is why when you may be feeling a certain way when you feel "something isn't right", you may be experiencing a chemical or hormonal imbalance for various reasons. Before hormones and signals can be sent to cells, they need a delivery system - one such substance is MK 677 (Ibutamoren).

In this article, we'll go over what Ibutamoren is and what its creation was intended to do. We'll also explore the benefits and side effects of its limited, but detailed, testing and trials. Finally, we'll show the best site to purchase for approved laboratory and research use.

What is Ibutamoren?

Cells have certain ways they receive messages, called receptors. Ibutamoren works in a way that simulates the activity of these receptors (specifically hormone receptors for this substance) which work to increase the production of human growth hormone in the body. The natural way this is released in the boy is through the hormone "Ghrelin", which is released in the gonads of both males and females, as well as certain digestive systems when hunger is present (stomach, kidney, small intestines). Overall, Ibutamoren was created as a more effective version of this hormone - helping in the reparation of muscles, tissues, and other regenerative properties.

Although often confused as an anabolic steroid or a SARM, Ibutamoren is a different class altogether, called a human growth hormone (HGH) secretagogue. The root word there is "secrete," which directly explains MK677's functions - acting as a messenger between cells to secrete more growth hormone. It is often confused with steroids, but it functions much differently. While steroids mimic testosterone and provide androgenic properties and side effects, Ibutamoren has no direct impact on any such androgen suppression or production. This is why the bodybuilding community has taken notice.

What Are The Benefits And Side Effects Of Ibutamoren?


  • Ibutamoren is not intended for retail use but was created as a remedy to fight certain degenerative diseases. As such, the goal of therapy through Ibutamoren is focused on increasing the production of HGH healthily and sustainably. It is worth mentioning that this is not widely available for trials and most studies have been done on rodents and other animals. Healthy HGH production can:
  • Promote positive muscle growth in patients that are suffering from atrophy or certain weakening conditions, such as cancer, HIV, and AIDS.
  • Increases bone health by helping to halt tissue degeneration, it also increases bone density - great for those with arthritis and osteoporosis.
  • If approved, as a supplement to myriad age or injury related to muscle, tissue, bone, and ligament degradation.
  • Repairs of cells and platelets, which can help those who injure, bruise or lacerate easily - possible research has gone into those who cannot close wounds themselves, such as hemophiliacs.
  • Aids in the breakdown of fatty acids, which lowers LDL (bad cholesterol), improving the metabolic health of both your cardiovascular and somatic systems.
  • To many people's astonishment, Ibutamoren seems to (in some studies) also improve REM sleep quality, especially in those with sleep disorders. 

Side Effects

Because Ibutamoren is neither a SARM nor a steroid, it only functions as a messenger, meaning it cannot cause any side effects directly. Ibutamoren's only function is to increase (or exponentially begin producing) human growth hormone within the body for a temporary period of its half-life. Overdosing on HGH secretagogues can:

  • Increase the glucose energy within the cells as a substitute for fatty acids, which can spike your sugar levels. Those with diabetes, blood pressure issues, or low-insulin levels would be impacted the hardest.
  • Delivers more water to your muscles to stay hydrated and to promote strength and recovery. Taking too much will retain a lot of water - causing stiffness, bloating, and flexibility issues.
  • It contributes to lethargy within the body, making you more prone to laziness and lack of productivity.

Where Can I Buy Ibutamoren?

Pure Rawz is the premium site to purchase all of your supplemental needs. They have natural and proven supplements that include cannabis, protein, and certain nootropics, but also source different products for research purposes as well, including SARMs. Although Ibutamoren does not target the androgenic receptors, it is grouped within the same category for offering many of the same benefits. They provide many disclaimers on the site and include information on how it works, what the half-life is, what studies have been conducted and how it affects body composition and sleep quality.

It is important to note that this has not been approved by the FDA and is not allowed to be prescribed or purchased for personal use. Pure Raws provides an independently issued certificate assuring purity and concentration, for research purposes only.


Is Ibutamoren the same as growth hormone?

Ibutamoren isn't directly considered a growth hormone, it is a delivery vehicle that promotes the endocrine system within the body to create more growth hormones for use within cells. This leads to muscle repair, muscle growth, and healing.

How do you take ibutamoren?

Ibutamoren isn't a directly controlled product and has not been approved for retail consumption. If clinical trials are passed and approved, doctors or suppliers would be allowed to prescribe or sell MK677 or any MK677-related products. It would most likely be administered orally as a pill, beverage, or drops - and possibly topically in certain creams to promote healthy skin care and muscle repair.

Is ibutamoren a SARM or a steroid?

Neither. Although it is often grouped more closely with SARMs as it does not create any androgenic properties, ibutamoren is a secretagogue that stimulates hormone production, unlike SARMs which bind directly to androgen receptors to promote muscle growth.
