Tout savoir sur MK 677
MK 677 is a molecule that promotes the secretion of growth hormones.

How it works

MK 677 is a chemical substance whose main function is to promote the secretion of growth hormones and IGF-1 in the body. It acts in the same way as receptors for ghrelin, a hormone produced by endocrine cells in the intestine. Studies have also shown that Ibutamoren does not affect cortisol levels in the body.

This experimental formula was originally developed to treat growth hormone deficiencies. It is also attractive to bodybuilders because it promotes muscle mass gain. In addition, it has many other effects of interest to the body.

What are the effects of MK 677 on muscles?

Research has shown that the effects of MK 677 go far beyond the low muscle mass gain.

Increased appetite

This first advantage can also be a disadvantage, but remains inseparable from the consumption of MK 677. This substance indeed increases appetite since it promotes the secretion of ghrelin. It should be noted that the main role of this hormone is to stimulate the desire for food. Its quantity decreases gradually as the consumer approaches satiety.

Increase in the rate of growth hormones in the body

Studies have shown that Ibutamoren may be effective in treating growth hormone deficiency in children. This drug promotes the production of IGFBP-3, IGF-1 and growth hormones. In addition, it has no influence on cortisol, glucose, insulin prolactin or thyroxine levels. It produces the same effect in adults compared to HGH, but leads to an increase in insulin and glucose levels.

Increase in muscle mass

Its ability to stimulate the level of growth hormone and IGF-1 in the body makes MK 677 a powerful ally in optimizing muscle growth. In other words, this substance promotes an increase in muscle mass and volume. Positive results have been observed in patients suffering from HGH deficiency, particularly those over 60.

Accelerated recovery

Ibutamoren has been reported to promote the formation of muscle tissue. This experimental formula could therefore reduce the recovery time after a weight training session. It also actively participates in the repair of tendons and ligaments during periods of intense training. Finally, this substance strengthens bones by increasing their density.

Gaining lean muscle and losing fat

MK 677 would be effective for rapid loss of fat mass according to the many users included in the experimental study. In addition, it promotes the gain of lean, therefore fat-free mass.

Other interesting effects of MK 677

Ibutamoren also optimizes the quality of sleep, especially in the fourth phase, known as the paradoxical phase. As one effect leads to another, this drug also increases cognitive and concentration capacity. Finally, it is said to have important beauty benefits by revitalizing and rejuvenating the skin, nails and hair.

Does MK 677 have any side effects?

Like all chemical substances and medications, MK 677 has side effects. Here are those that have been reported since the studies began:

  • Increased appetite;
  • Water retention;
  • Muscle cramps;
  • Sleep up to 12 hours;
  • Increased blood pressure;
  • Heart failure ;
  • Increase in blood sugar.

MK 677 has several side effects.

How do I take MK 677?

The dose of MK 677 depends on the results recertified. Take approximately 30 mg per day to promote fat loss and around 20 mg per day for muscle strengthening. However, I recommend that you do not take more than 30 mg. An overdose will not increase the capacity of the drug and could on the contrary cause adverse effects. In addition, the treatment should be continued for a longer or shorter period of time, as the effects are only observed after a few weeks.

Is MK 677 an anabolic steroid?

Ibutamoren is not an anabolic steroid, but its effects are similar. Ibutamoren helps increase muscle mass, but does not act on androgen receptors. It is therefore less dangerous for human health and does not produce hormonal disorders such as testosterone deficiency after the treatment. Effects on appearance such as virilization or gynecomastia are also avoided. Finally, MK 677 does not attack the liver or the heart.

Where can MK 677 be purchased and at what price?

MK 677 is an experimental substance. It is therefore difficult to find it on the market, especially in pharmacies and stores. However, it is possible to buy the drug online at various prices. For my part, given that the product has not yet been officially validated, I recommend caution and avoid using it. It is better to get products that have already proven themselves.

My opinion on MK 677

Most bodybuilders who have tested MK 677 in experimental studies have stated that the product is indeed effective in building muscle mass. In addition, the side effects would be less compared to other products of the same type. Many researchers even claim that this innovative formula could revolutionize the world of bodybuilding.

For my part, I agree with my opinion: it is better to wait for the final results of research before starting to use this substance. Its effects as well as the risks on the short and long term will then be well known.

Crazy Bulk food supplements


The consumption of MK remains questionable. To boost your sports performance and take muscle serenely, I recommend that you adopt healthy and less risky food supplements such as those of the Crazy Bulk brand.

In addition, your endurance is improved and you resist fatigue while recovering better.
