1.What is MK 677?

Ibutamoren (INN) (developmental code names MK-677, MK-0677, L-163,191; former tentative brand name Oratrope) is a potent, long-acting, orally-active, selective, and non-peptide agonist of the ghrelin receptor and a growth hormone secretagogue, mimicking the growth hormone (GH)-stimulating action of the endogenous hormone ghrelin.It has been shown to increase the secretion of several hormones including GH and insulin-like growth factor 1 (IGF-1) and produces sustained increases in the plasma levels of these hormones without affecting cortisol levels.

Ibutamoren has been shown to sustain activation of the GH-IGF-1 axis and to increase lean body mass with no change in total fat mass or visceral fat. It is under investigation as a potential treatment for reduced levels of these hormones, such as in children or elderly adults with growth hormone deficiency, and human studies have shown it to increase both muscle mass and bone mineral density, making it a promising potential therapy for the treatment of frailty in the elderly.As of June 2017, ibutamoren is in the preclinical stage of development for growth hormone deficiency.

Since MK-677 is still an Investigational New Drug, it has not yet been approved to be marketed for consumption by humans in the United States. However, it has been used experimentally by some in the bodybuilding community. Since it chemically mimics the hormone ghrelin, it functions as a neuropeptide in the central nervous system and crosses the blood-brain-barrier. According to some recent research and discussion, there is a concern that its particularly longer half-life might over-stimulate the ghrelin receptors in the brain.

2.What is MK 677 used for ?

MK-677 is a non-peptide oral growth hormone that stimulates the release of GH through receptors in the pituitary gland and hypothalamus, which are different from growth hormone releasing hormone receptors. mk-677 is an effective oral growth hormone secretion, which mimics the effect of GH in stimulating endogenous hormones. It has been shown to increase release and produce a continuous increase in plasma hormones, including growth hormone and IGF-1, but does not affect cortisol levels.

MK 677 is a very effective product, especially for expansion cycles. This is why after taking MK 677, I am still wondering whether this product needs a post-cycle treatment or PCT. However, since the product does not inhibit the production of natural testosterone, nor does it affect the production of natural growth hormone, this means that there is no need for post-cycle treatment.

MK677 belongs to one of SARMS series products. Like most other SARMS, MK677 changes their function in the body by locating specific androgen receptors. As a result, this type of stimulation can mimic the anabolic effects of steroids and prohormones. MK 677 is very similar to peptides like Ipamorelin and GHRP-6, but you will not experience any typical side effects.

In addition, the positive effects of MK 677 in increasing the pulse intensity of growth hormone are as follows:

 Inhibit the signal of somatostatin receptor.

 Slow down the activity of somastostatin in the system.

 Improve the growth hormone signal amplification of growth hormone releasing hormone (GHRH) and increase the overall production and release of GHRH.

3.What is the side effects of MK 677?

Increased appetite.

Some users have increased hunger when running MK 677. However, for me personally, it is manageable. Just make sure you are eating the right foods, and these foods will fill you well.

Briefly drowsy.

When you take 677, you can experience a feeling of sleep throughout the day. This usually only lasts for a short period of time, and a good cup of coffee will help you get through it.

Numb hands.

This is because the level of growth hormone in the body is elevated. This may seem scary at first, but you will get used to it later.

The side effects of MK 677 are nothing to be afraid of. I mean, the side effects of MK 677 are no different from those of hormones. I would definitely recommend MK 677 to everyone who is interested in trying it.

Some people claim that it can lower GHIH levels, but this has yet to be determined.

Any compound that can increase your growth hormone and insulin-like growth factor-1 levels will naturally cause some unpleasant reactions in your body. However, MK 677 is a mild compound and therefore safer than its counterparts. The only annoying side effect, you can expect its use to be extreme laziness. However, don't worry, this side effect is not uncontrollable. You can reduce your dose for a period of time to reduce the intensity of this side effect.

4.You should know more about other sarms like MK 677?

  1. What is SARMS? Is SARMS a drug?

SARMS is a selective targeting androgen receptor modulator.

Corresponding to steroids by regulating the acceptance and utilization of androgens by one's own muscle cells. Steroids are exogenous androgens, while SARMS regulates muscle absorption and use of androgens, both exogenous and endogenous. So the results of steroids + SARMS can be imagined!

SARMS is not a medicine in the strict sense, it is a substance between supplements and medicines.

  1. What are the characteristics and advantages of SARMS?

SARMS, a selective androgen receptor modulator, is considered a bridging compound in bodybuilding. It produces results similar to steroids, but does not produce the same side effects. All SARMS does not suppress internal organs, has no hepatotoxicity, and does not transfer to females .

  1. What is the introduction of SARMS common supplies?

SARMS series of high-quality products: S4, YK-11, GW-501516, LGD-4033, MK2866, MK-677, RAD-140, LGD-3303, SR9009 The specific features can be found in previous tweets.

MK-2866: MK2866-selectively perform anabolic activities on certain ARs, which is helpful for maintaining and increasing lean meat mass and resilience.

LGD-4033-a powerful non-steroidal bodybuilding supplement used to increase muscle mass and reduce body fat

Ostarine (MK-2866)-selective anabolic activity, very suitable for maintaining and increasing lean body mass and training

S4 (Andarine)-Select bone tissue (mainly low-grade virilization), aimed at treating osteoporosis, and will not produce the development of the prostate and other secondary sexual organs

GW 501516 (Cardarine)-burns fat, maintains muscle loss, and helps you receive the next level of training. Known as the "king of endurance supplements", it is used by top athletes and bodybuilders.

RAD140 (testostelone)-a powerful non-steroidal bodybuilding testosterone booster. Helps increase endogenous testosterone naturally without the risk of side effects.

  1. What is the use of SARMS?

All SARMS series are oral, and MK2866 requires PCT. SARMS can tailor the program according to the specific own situation, which can be superimposed, used alone, or mixed with steroids.

  1. Can women use SARMS?

Women can use some of these products at reasonable dosages.

MK677,MK2866,GW501516,SR9009,LDG-3303 are suitable for women use

5.Where to buy sarms like MK 677?
