V-Ibutamoren (Mk-677) 25mg


Pack: 30 caps (25mg/cap)

MK-677 is taken orally. The most common dosing range is 25mg per day.



ORAL HGH Reverse Pharmacology is the center at which MK-677 was first introduced, with its main focus being to trigger the pituitary gland to secrete, or ‘release,’ growth hormone. Like most substances created from a lab, their initial intentions and goals differed. Originally Ibutamoren was to be a way to produce positive reactions for a myriad of health issues including muscle wasting, osteoporosis, and even obesity. Secretagogues can be responsible for allowing insulin to release as well.

Though early in the testing phase, there is no doubt that the initial feedback has been overwhelmingly positive. Trials of the orally administered substance displayed a direct correlation between its use and a spike in IGF-1. Insulin growth factor is beneficial for a multitude of health related ailments because it has healing properties. MK-677 has been proven to help the cutting phase for ardent muscle builders, and has encouraged healthier sleep patterns. The strengthening of bone density has also been present in numerous cases.

Why Bodybuilders Love Ibutamoren?

MK-677 is a SARM, which is a selective androgen modulator receptor. SARMs are frequently discussed in weightlifting forums because they are a viable alternative to anabolic steroids. While effective in muscle growth, steroid use diminishes yearly because their side effects can cause long term damage. This includes irritating the prostate, shrinking the testes, and in extreme cases, enlarging the heart. SARMs mimic the output of anabolic steroids, while cutting back the dangers dramatically. Selective androgen modulator receptors are able to accomplish this successfully by not affecting every tissue inside us. Instead, as their name states, they only instigate change in certain areas, namely muscles. Lean body mass is greatly coveted by people who workout, and those who have tried MK-677 state that it delivers this goal combined with a diet plan seamlessly.

How Can This SARM Help Me Specifically?

1. Ghrelin receptors (GHSR) are critical to growth hormone escaping from the brain.

Ibutamoren’s duty in this process is to bind to a GHSR receptor and copy its intended effect. The aftermath is your body utilizing an abundance of this hormone without substantially increasing other hormones. It is a game changer in the fitness world because it does not alter cortisol. This is pertinent to those that take MK-677 because it will not block the immune system from quick recovery times

2. MK677 Has no effect on Cortisol Profiles

Nine healthy young men participated in a randomized, double blind, three-period cross-over comparison of orally administered placebo and 5- and 25-mg doses of MK-677…for 7 consecutive days…MK-677 had no effect on cortisol profiles. In particular, 24-h mean levels of plasma total and free cortisol and urinary excretion of free cortisol were similar under all conditions.

3. Ibutamoren bars somatostatin receptors.

These receptors inhibit growth hormone from releasing in larger quantities. When somatostatin receptors are not allowed to disrupt growth hormone, it amplifies the production of GHSR. This is desired for a wealth of positive actions within the body like increasing size gain and the ability to attain lean muscle mass, the healing of tendons and ligaments at a swifter rate, and oxidizing fat more efficiently. The fact that brittle bones can regenerate dramatically proves why it has been linked to treatment of osteoporosis.

What Are The Side Effects Of Ibutamoren?

It is fortunate that MK-677 does not mimic anabolic steroids in what they leave behind, which in most cases are enlarged organs, and even destruction to the liver. Instead, the only drawback seems to be a bigger appetite. This is not a surprising sidebar to taking Ibutamoren, as GHSR is linked to signaling hunger in the brain. Taking Ibutamoren can also spark incessant dreaming, similar to over the counter melatonin.

What Are The Doses Of MK-677 And When Do You See Results?

Various schools of thought have placed the dose range from 25mg a day up to as much as 50mg, but the jury is still out on the ideal region for maximizing its effects. Users have cited an uptick in endurance at lower dosage levels. You can burn fat with relative ease without ingesting too much in a 24 hour period.

The levels of IGF increase dose dependently, so it stands to reason that if your end game is more solid muscle, a higher dose is essential. The logical starting point is beginning low, and working your way up until you find what you are looking for as far as impact. Users typically show positive change in a month, with fat burning starting to occur within a couple of weeks.
