How MK-677 Works

Ibutamoren mk-677 is a selective silent modulator of growth hormone receptors (SmoR). It is thought to increase growth hormone secretion by increasing the number of Growth hormone receptors on the surface of the cells that produce the hormone.


MK-677 may also increase the half-life of growth hormone, allowing it to stay active in the body longer. Reducing the time between each pulse of the hormone reduces the amount of growth hormone required to reach the desired effect. This drug may be useful for muscle growth, fat loss, and the treatment of certain types of dwarfism.

How RAD-140 Works

RAD-140 also called Testolone is a selective androgen receptor modulator. That means that RAD-140 has an androgenic effect on muscle tissue while having almost no effect on other tissues in the body. SARMs are of particular interest to researchers because they are selective about where they work. They mostly target muscle and bone tissues and appear to have minimal effects on the prostate and other organs. The chemical structure of RAD-140 is very different from the structure of steroid hormones like testosterone. Thus, the pathways that convert testosterone into other hormones (like estrogen) cannot act on Testolone[1].


Based on a study on rats, some researchers have suggested that RAD-140 could activate receptors in injured regions of the brain. In the brains of rats given RAD140, MAPK activity increased, thus protecting neurons from damage [5].



What to expect?

Recover faster from workouts

Increasing growth hormones means that muscle cells can recover a lot faster. So, your muscle needs less time to go back to the gym or on the field for a hardcore session. Muscles also feel sore for a much shorter period.


Build Muscle

Since MK-677 helps your muscle recover faster, you will build a lot more muscle mass in a shorter period! Muscles are not built in the gym but during recovery. Better recovery better gains.


Help Recovers From Injuries

An increase in HGH production means that all cells are recovering faster. Not only the muscle but also the joints, tendons, and ligaments. Ibutamoren also creates a little bit of water retention, especially in joints which is awesome for joint health!

Can increase lean muscle mass by more than 10% in just 28 days [2]

Increases nitrogen retention in less than 14 days [2]

Feel Younger, Slow Aging

One of the key factors of aging is the fact that past 30 years old the level of growth hormone decline pretty fast. That’s why many athletes and celebrities take HGH to stay younger and healthier longer. With MK-677 it’s now easier than ever to get the same results!


Boost Metabolism, Burn Fat

Cells need energy to recover and regenerate, in the human body, energy is calories. Having higher levels of HGH and recovering faster mean that you burn a lot more calories on a daily basis. This leads to burning fat! Ibutamoren also acts directly on fat cells to lose fat faster!

Other Benefits

Ibutamoren improves sleep quality providing you with a longer REM sleep cycle and shorter sleep latency. MK-677 also decreases LDL, which helps cardiovascular health.2

Boost Metabolism, Burn Fat

Being more anabolic also means that you are more likely to retain muscle mass as you are consuming more calories than your body needs to maintain its current weight. High-protein foods are anabolic because they take longer to digest, and thus you are less likely to overeat because of their satiating effect.

Brain Effect

Androgens play an important role in protecting the brain. Moreover, they can reduce the risk of developing Parkinson’s disease. Androgens also have an anti-inflammatory effect on the brain. They can decrease the activity of microglia, which are macrophage cells that cause inflammation in the brain.

By reducing the activity of these cells, androgens can improve sleep quality and decrease stress. Furthermore, by increasing the level of serotonin and dopamine, androgens can improve the mood.[5].
