Is MK 677 (Ibutamoren) a Steroid?


Is MK 677 a steroid

MK 677 is a compound that is being touted as a potential replacement for steroids.

Steroids have been used in the fitness world for a long time, but they find their origin in the medical world.

While bodybuilders may abuse these substances, they were originally developed to treat individuals suffering from muscle wastage diseases. Steroids are sexual hormones. However, they are synthetic versions of them.

They include synthetic testosterone, estrogens, and progesterone.

The steroids most often are synthetic testosterone, which binds to androgen receptors and causes muscle growth.

MK 677 is not a Steroid, seeing as it is not a sex hormone, nor does it bind to the Androgen receptors as Steroids do. Thus, not only does MK 677 not look like Steroids, but it does not interact with the body as steroids do.

MK 677 is known as a Growth Hormone Secretagogue, meaning it will cause increased release of Growth Hormone by the pituitary gland.

It is not pure exogenous growth hormone, and because it is not replacing an exogenous hormone, it will also not cause downregulation of endogenous growth hormone production.

Steroids do this, as all steroid use will cause downregulation of testosterone production.

Let me explain further.

MK 677 vs Steroids – How do they work?

Steroids originated in the 1900s when doctors began experimenting with what would happen to depressed men if injected with testosterone. They soon found that these administrations helped and wondered if they could alter these compounds to make them accessible to others.

Steroids were developed one after the other, each being better and with fewer side effects than the last.

Boldenone was created from testosterone by creating a double bond at the 1 and 2 carbon, lowering this compound’s androgenic and estrogenic side effects.

On the other end of the spectrum, millions of people have suffered from growth hormone deficiency over the past 200 years.

Doctors began experimenting with growth hormone “boosters” called growth hormone secretagogues.

These compounds would interact with the pituitary gland and cause it to produce more growth hormones.

Such secretagogues include CJC-1295, GHRP-2/6, and MK-677 as well.

How do Steroids work?

Steroids can be classified as steroidal hormones, including Androgens, estrogens, and cortisol. Anabolic steroids are mostly androgens, but one or two are derived from Estrogen.

The human body has androgen receptors, and hormones in the body will activate that.

The hormones in question would be androgens; depending on the critical point and androgen in question, you will see different reactions.

Bone tissue androgen receptors will logically cause an increase in bone density and strength.

In contrast, androgen receptors in muscle tissue will cause a biological change resulting in increased muscle protein synthesis and tissue. Steroids will bind to all the androgen receptors in the human body.

How does MK 677 work?

The human body has a gland that will release growth hormone into the body to do everything it needs to. Growth hormone is important for growth in children. It is vital in adults as it regulates cell health and function.

Some individuals suffer from a growth hormone deficiency, either as children or as they age past 40.

Doctors have developed growth hormone secretagogues, like MK 677, that will interact with the pituitary gland and cause it to produce more growth hormone.

This is not replacing your growth hormone levels and will not cause downregulation of your production.

MK 677 is a growth hormone secretagogue, meaning it stimulates the release of growth hormone from the pituitary gland.

It does this by mimicking the effects of ghrelin, the “hunger hormone”. Ghrelin is released from the stomach in response to hunger and signals the pituitary gland to release growth hormone. MK 677 tricks the body into thinking it’s hungry, resulting in a surge of growth hormone.

MK 677 has been shown to increase muscle mass, decrease fat mass, and improve sleep quality. It also has some anti-aging effects, such as increased lifespan and improved cognitive function.

What does MK-677 do to the body?

MK 677 is a rather popular compound to increase natural growth hormone production. When you spend some time online, you will find MK 677 is often referred to as a SARM – selective androgen receptor modulator.

This could not be further from the truth.

MK 677 does not interact with the androgen receptors at all, and since it is a growth hormone secretagogue, it will only interact with the pituitary gland.

MK 677 can lead to:

  • Fat Loss: Due to the increased growth hormone levels, the body can break down fat from fat cells at a much higher rate. This free fatty acid can be used as energy, leading to fat loss and lean muscle mass
  • Increased Muscle: Growth Hormone will cause increased levels of IGF-1 levels in the body. This compound is quite anabolic and can cause muscle growth when combined with a good and high-calorie diet
  • Improved Recovery: Growth hormone levels have been directly correlated to recovery rates, so having more growth will mean better recovery

What happens to you when you take MK-677?

When you take MK 677, the body will naturally begin to produce more growth hormones. This is beneficial for several reasons, such as fat loss and muscle gain.

The way growth hormone would do this is by the following process:

  • The Pituitary Gland produces HGH. This starts circulating through the body and reaches the pancreas
  • In response to the presence of HGH, the Pancrease dumps both Glucagon and Lipase into the blood. Glucagon is a hormone that helps regulate blood sugar, while Lipase is a protein that releases fat from fat cells
  • Lipase proceeds to release fat from adipocytes into free fatty cells in the bloodstream
  • Glucagon circulates in the bloodstream and reaches the liver
  • In response to the presence of Glucagon, the liver dumps sugar into the bloodstream. This proceeds to raise blood sugar levels
  • In response to higher blood sugar levels, the pancreas releases insulin. Simultaneously, the liver releases IGF-1 (Insulin growth-like factor 1)

Does MK-677 have testosterone?

Mk 677 is known as a growth hormone secretagogue and has the molecular formula of C27H36N4O5S.

Mk 677 Ibutamoren formula

MK 677 has been developed to treat those who suffer from a deficiency in growth hormone.

MK 677 will interact with the pituitary gland to produce more growth hormone, meaning MK 677 cannot interact with androgen receptors. Testosterone is a sex hormone and has the molecular formula of C19H28O2.

Testosterone will interact with the androgen receptors in the body and cause a biological change reflected as increased muscle gain through increased protein synthesis.

MK 677 does not have testosterone as the two are massively different compounds. Testosterone is not orally active, meaning you cannot drink pure testosterone unless it has been altered.

MK 677 will not interact with Testosterone levels at all. They do not have the same side effects either, so even if you take them, you would know one from the other.

Is MK-677 a growth hormone?

Growth hormone has been used in the medical field for several years and has even been used as a treatment for obesity.

Growth Hormone will directly increase fat oxidation levels and is even called an “anti-aging” compound. Various growth hormones, such as Somatropin, Zomacton, and Humat, are available on the market.

The biggest thing differentiating actual human growth hormone from MK 677 is that real human growth hormone is a sequence of amino acids bound by peptide bonds.

This is why growth hormone is often referred to as a polypeptide.

growth hormone

MK 677 is not classified as a growth hormone but is rather classified as a growth hormone secretagogue.

MK 677 will not act as growth hormone but rather cause increased growth hormone production by your pituitary gland.

Mk 677 is also not classified as a peptide, as it is not comprised of a chain of amino acids.

Side Effects of MK 677

Most drugs will have some side effects; even Aspirin has side effects.

Doctors and chemical engineers will try to remove as many side effects as possible before releasing the compound to the public.

MK 677 is no different and can cause the following side effects: 

  • Insulin resistance: Due to the mechanism of action, increased growth hormone levels can lead to increased blood sugar and insulin levels in the body. Doing too frequently or excessively can lead to insulin resistance and diabetes.
  • Water retention: Increased levels of growth hormone have been linked to increased water and sodium retention
  • Carpal tunnel syndrome: Due to the increased water retention, growth hormone has been known to cut off capillaries in smaller areas of the body which can cause carpal tunnel syndrome

FAQs

Is MK-677 any good?

Mk 677 will often be grouped with a collection of other products called SARMs that have been accused of not being very effective. Mk 677 is a great growth hormone booster.

However, it is not as effective as an actual Growth Hormone.

How long should I take MK-677?

While Mk 677 can be taken indefinitely, it is best to avoid caution and only take it for 10 – 12 weeks.

Do I need pct after MK-677?

MK 677 will not require a PCT since it does not cause suppression of any endogenous hormones.

Does MK-677 promote hair growth?

MK 677 could promote hair growth. See, Mk 677 will cause an increase in human growth hormone levels. This will, in turn, lead to increased IGF-1 levels, which can lead to hair growth.

What should I stack with MK-677?

While stacking is incredibly common in the fitness and PED world, you must ensure you do not stack the wrong compounds with one another.

MK 677 can be stacked with any Steroid, any SARM, and some people have found massive success when they stack it with actual human growth hormone.

Is MK-677 Safe and healthy to use?

As long as you manage your blood glucose levels and do not abuse the compound, it should be safe to use.

Is MK-677 Legal to use worldwide?

It is impossible to say if it is legal worldwide because some countries, like Australia, have very specific laws regarding research chemicals. You are better doing some research about the laws in your own country.

Final Thoughts

In conclusion: MK 677 (Ibutamoren) is not a steroid, but it is often mistaken for one. It is actually a growth hormone secretagogue, which means that it helps the body produce more growth hormones. This can have some amazing benefits for athletes and bodybuilders alike.

If you’re looking to increase your muscle mass or lose weight, our MK 677 (IBUTA 677 we recommended above) may be worth considering.
