Ibutamoren (MK-677): Unlocking Growth Hormone Secretion
Written by

Ibutamoren (MK-677, MK-0677) is a non-peptide, selective, long-acting agonist of ghrelin receptors.

MK-677 mimics the action of ghrelin, which, in turn, possesses properties of another hormone — growth hormone-releasing hormone (GHRH).


And the main task of the SRG is precisely to initiate the synthesis and secretion of the anterior pituitary growth hormone.

Ibutamoren

Ibutamoren attaches to ghrelin receptors and activates them — this signals the body to start producing growth hormone.

And here's what's remarkable: at the same time, MK-677 significantly slows down somatostatin secretion, which is, hormone that suppresses the secretion of growth hormone. As a result, the surge in somatotropin is prolonged, and the peak is significantly higher than natural.

Finally, another interesting feature: ghrelin simultaneously initiates the secretion of two more hormones — cortisol and prolactin, whereas ibutamoren does not (there is still no consensus about prolactin)

Since MK-677 is considered an extremely important and promising agent — it is planned to use it both for treating growth delays in children and in anti-aging therapy — there have been many studies on it.

Dosages

How to take ibutamoren? A daily dose of 25 mg is usually used. At such a dosage, ibutamoren allows for a noticeable increase in IGF-1 concentration in the blood, indicating a significant increase in growth hormone secretion.

Essentially, 25 mg of MK-677 per day can be compared to injecting approximately 2 IU of recombinant growth hormone. This is regarding the peak value — if you take such a parameter as the area under the curve, it is approximately the same for ibutamoren as for a single injection of 3.5-4.5 IU of recombinant somatotropin per day.

Effects on the Body

As a result of ibutamoren use, a noticeable increase in "dry" muscle mass was observed. On average, about two and a half kilograms over the same 8 weeks, but the drug did not affect fat tissue, although there was an increase in the rate of metabolic processes.

Ibutamoren is also considered as a means to overcome osteoporosis. Additionally, it allows for improving sleep quality and facilitating falling asleep, increasing energy levels, and strength indicators.

    Some people now take it together with growth hormone injections. I don't understand this approach.

      The use of stimulants alongside growth hormone is possible. Peptides from the "GHRP group" and Ibutamoren can enhance the activity of growth hormone in terms of IGF-1 production.

    From practice: Before the pandemic, I took the medication in the Netherlands. I felt the effect of rapid recovery, including for the joints and ligaments. I had somatotropic hormone tests done. Before taking it, it was 0.05, and after it became 0.37. At one point, I took the test in the morning. Then, when the company from Rotterdam disappeared, I tried Indian medication a couple of times. It didn't do anything. It's probably better to stick with 3 units of the normal growth hormone.
