MK-677, also known as Ibutamoren or Nutrobal, is a Human Growth Hormone secretagogue; this means that it will engage the pituitary gland to secrete HGH. MK 677 has been shown to increase HGH levels. This gives the benefits of increased lean muscle mass, better sleep, lower LDL cholesterol levels, improved healing of muscle, bone, ligaments, improvements in hair and skin, and a greater overall sense of well-being. MK677 has been shown to not suppress the body’s own HGH production, making it an effective treatment for boosting HGH levels safely. Order MK-677 for sale online at Paradigm Peptides today.

Buy MK 677 ( Ibutamoren )

MK 677, also known as ibutamoren, nutrobal, and ibutamoren mesylate, is a selective androgen receptor modulator. This SARM works as a growth hormone secretagogue. In other words, it helps promote the secretion of natural growth hormone in the body, thus inducing muscle mass increase, fat burn, and more! SARMs are the better compound because, unlike anabolic steroids that have serious side effects, these compounds have very few side effects in general. MK-677 works by attaching itself to ghrelin receptors in the body. By doing so, the person using it may experience things like higher GH and IGF-1 levels. This allows for the creation of lean muscle mass as well as an increased appetite and other benefits.


Sleep Studies with MK-677

In a study done with eight younger subjects between the ages of 18 and 30 and six older subjects between 65 and 71 years of age, MK 677 pills were tested for their effectiveness in improving sleep quality. For both groups, young and old, three treatment phases of 7 days each occurred. During this stretch of the trials, researchers sorted the individuals into either the placebo group or groups meant to take either 5mg or 25mg of MK-677. At the conclusion of the study, MK677 had the ability to improve sleep quality and correct hyposomatotropism related to aging.


Other Studies Done with MK 677

Two other notable studies include one done with males between the ages of 19 and 49 and another done with men and women ages 60 to 81. In the study done with the younger males, MK677 was studied for its effects on GH secretion, body composition, and energy levels. During the duration of the study, which was eight weeks, the subjects were each given a daily dosage of MK-677 at 25mg per day. At the conclusion of the study, MK 677 had been accepted by the subjects’ bodies. They also had energy dissipation, and their body composition took on an anabolic nature. There were sustained increases of fat-free mass as well as a temporary increase in basal metabolic rate. In the second study, a two-year double-blind study, the older men and women (ages 60 to 81) were given a daily dose of 25mg. Like the previous study, this study also was to test fat-free mass and the decrease of abdominal visceral fat. The participants in the test group saw a significant increase in both GH and IGF-1 without any notable adverse side effects. Not only that, it significantly increased fat-free mass and showed the ability to increase bone remodeling in the participants.


The Benefits of Using MK 677

It’s already been alluded to that using IGF increases lean muscle mass and increases your overall appetite. However, there is more to this SARM than just these two key points. Other studies have proven that it can help memory and cognitive function because it induces the production of both GH and IGF-1. IF you’re having problems getting a full night’s rest, MK 677 pills may be for you as well. MK 677 can help you get a restful night’s sleep. Why is this beneficial? Your body needs time to recuperate and rejuvenate, and most of this is done while we sleep. When we don’t get that rest, we don’t get the healing that we need. On the other hand, if you want to stay up later and engage your sex life, MK677 can help in that department by kicking up your libido. It’s a win-win situation!


  • Improved Memory
  • Restful Sleep
  • Better Moods
  • Increased Lean Muscle Mass
  • Improved Metabolism
  • Increased Libido
  • Increased Production of GH and IGF-1


Possible Side Effects of MK 677 Pills

Some side effects can occur when using MK 677; however, they’re typically mild and if you really think about it, the benefits are worth the side effects. Some of the side effects that have been most common include things like water retention, lethargy, and appetite increase. Regarding the water retention, this more commonly occurred when individuals consumed more than the recommended daily dosage. Therefore, if you don’t go over the recommended amount you have the potential to avoid this side effect all together. Regarding lethargy, most recommend taking it in the evening, so you don’t feel off base all day and you’d still be getting a good night’s rest. Finally, when it comes to appetite, this basically means that your body is burning off all the extra fat, so as you can see, even the negatives can be positives.

Side Effects: 

  • Increased Appetite
  • Water Retention
  • Lethargy


Dosage Protocol for MK 677

MK 677 has a straightforward dosing protocol and cycle length. Essentially you want to take MK 677 pills on an empty stomach. This can be done one to two times a day, depending on your preference. If you decide to go the one-dose route, stick with a dosage of 25mg for the day. However, if you choose to do the two-dose route, taking two 12.5mg doses every day, either way, you can achieve the same results. The other thing to consider is cycling length. A typical cycle of MK677 lasts between eight to twelve weeks, anything shorter, and you risk not seeing the full potential of the SARM.
