Key Takeaways

  • MK677 peptide is a promising supplement among fitness enthusiasts due to its following benefits of increased muscle growth, fat loss, and increased energy levels, but its effectiveness long-term are not yet known.
  • Studies show that MK677 may assist with height growth only until the growth plates remain open, which is typically until hitting puberty.
  • While many users report positive results from using MK677 peptide, there are potential side effects to be aware of, such as increased hunger, water retention, and decreased insulin sensitivity.
  • As with starting any new supplements, it’s important to do your analysis, consult with a healthcare professional, and be aware of the risks and benefits. MK677 peptide may be a viable option for some individuals, but it’s not a miracle solution and should be used in conjunction with a healthy diet and exercise regimen.

What does MK677 do?

MK677 peptide, also known as Ibutamoren, is a growth hormone secretagogue that stimulates the production and release of growth hormone and insulin-like growth factor 1 (IGF-1) in the body [1].

Initially developed as a potential treatment for conditions such as growth hormone deficiency, muscle wasting, and osteoporosis, it has gained popularity among athletes and fitness enthusiasts as a performance-enhancing supplement.

MK677 works by binding to and activating the ghrelin receptor, which is responsible for regulating hunger, energy expenditure, and increasing growth hormone GH levels. By stimulating the production of growth hormone and IGF-1, it promotes muscle growth and repair, reduces body fat, and increases bone density.

It also has potential benefits for improving sleep quality, cognitive function, and immune system function.

Does MK-677 increase height?

While MK-677 has been shown to increase the levels of growth hormone and insulin-like growth factor 1 (IGF-1) in the body, there is no scientific evidence to support the claim that the compound can increase height in adults.

Can a Growth Hormone Secretagogue cause Height Growth?

Growth hormone is primarily responsible for stimulating growth during childhood and adolescence, when the growth plates in the bones are still open, especially during puberty. After the growth plates close, usually around the age of 18-20, the body’s ability to grow in height is limited. While growth hormone secretagogues have been used to treat children with growth hormone deficiencies and other conditions that affect growth, it is not typically used for height enhancement in adults. 

Especially in women, growth hormone levels tend to decline after puberty, and while there is some evidence to suggest that growth hormone therapy may have potential benefits for postmenopausal women, more analysis is needed to determine its long-term safety and efficacy in this population.

In fact, there is some evidence [2] to suggest that long-term use of growth hormone therapy and growth hormone shots in adults can lead to adverse side effects, such as joint pain, carpal tunnel syndrome, and an increased risk of certain types of cancer.

Therefore, it is not recommended to use MK-677 or any other growth hormone secretagogue for the sole purpose of increasing height in adults.

MK677 Height Growth Reddit Results

Here’s a recent discussion on Reddit regarding MK-677 peptide and height growth. The user went on to take the medicine for over 6 months and discussed his results, read on to find out more.

As of today, August 11, 2022, I’ve been taking MK-677 for 194 days or a little more than 6 months.

Measurements taken:

Day 8, February 5, 2022: 5’9.57” 5:30 p.m. (Initial measurement)

Day 31, March 1, 2022: 5’9.69” 7:30 p.m.

Day 62, April 1, 2022: 5’9.92” 8:19 p.m.

Day 92, May 1, 2022: 5’10.12” 5:43 p.m.

Day 122, June 1, 2022: [ Forgot to take measurement πŸ™ ]

Day 153. July 1, 2022: 5’10.24” 5:27 p.m.

Day 194, August 11, 2022: 5’10.39” 5:36 p.m. (Final measurement)

Side-effects I experienced at 20-25mg/day: I had a remarkable increase in my appetite as expected, however, this tapered off to normal after the first month. My sleep was wonderful, but I had vivid and bizarre dreams at first. I noticed an improvement in my physique with a better pump during workouts. The water retention in my face was not that noticeable for me personally throughout these six months. I bought a BGL monitor soon after I started and my levels fortunately never reached near pre-diabetic or diabetic levels, but my diet was on point throughout the six months [3].

MK 677 Summary

MK 677

MK 677 is commonly grouped with SARMs when in reality it is not a SARM at all. Regular SARMs will bind to the Androgen Receptors in the muscle tissue (and bone tissue as well) to cause an increase in muscle protein synthesis.

MK 677, however, is a Growth Hormone secretagogue, meaning it will not interact with the Androgen Receptors at all, but only cause an increased release of Human Growth Hormone (HGH) from your own Pituitary gland.

Increased HGH can lead to increased fat loss [2], and muscle gain, and even improve overall life quality.

Because MK 677 does not interact with the endocrine system, it is the β€œSARM” with the least side effects, making MK 677 a very safe SARM and great for beginners.

What can MK677 be used for?

MK677 is a selective agonist of the ghrelin receptor, which can increase levels of growth hormone and insulin-like growth factor 1 (IGF-1) in the body.

While there is no scientific evidence to support the claim that it can increase height in adults, MK677 has been shown to have several potential therapeutic uses.

One of the most well-established uses of MK677 is in treating growth hormone deficiency in children and adolescents. This condition can lead to stunted growth and development, as well as other health complications.

By increasing levels of growth hormone and IGF-1 in the body, MK677 can help to promote normal growth and development in these individuals. In addition to its potential use in treating growth hormone deficiency, MK677 has also been studied for its potential effects on muscle growth and fat loss.

Studies have shown that MK677 can increase lean body mass and muscle strength in older adults, as well as reduce body fat mass in overweight and obese individuals [4].

There is also some evidence to suggest that MK677 may have an effect on blood sugar levels, as it has been shown to increase insulin sensitivity in some studies. However, the effects of MK677 on blood sugar regulation are not well understood and may vary depending on individual factors such as diet and exercise habits.

One potential concern with the use of MK677 is its potential impact on insulin resistance. Research has shown that MK677 may increase insulin resistance in most people, particularly those who are already at risk of metabolic disorders such as Type II diabetes.

However, it’s important to note that these effects may not be as pronounced as those seen with other anabolic agents, and more studies are needed to determine the long-term safety and efficacy of MK677 for these purposes.

Is MK677 Legal?

MK677 is not currently approved by the US Food and Drug Administration (FDA) for any medical use [5, 6]. This means that it is not available as a prescription medication in the United States. The peptide currently available in the market is for research and educational purposes only. 

It’s worth noting that the regulatory status of MK677 can vary by country. In some jurisdictions, it may be classified as a prescription medication or a controlled substance. Therefore, it’s important to check local laws and regulations before using MK677 or any other performance-enhancing substance.

MK677 vs Other Compounds for Height Growth

MK677 vs Human Growth Hormone

While MK677 and Human Growth Hormone (HGH) are both used for their muscle-building and fat-burning effects, they work through different mechanisms. MK677 stimulates the body’s own production of growth hormone, while HGH is a synthetic version of the hormone that is directly injected into the body. Also, HGH tends to be more potent and faster-acting than MK677 peptide. 

MK677 vs GHRH & GHRP

MK677, GHRH, and GHRP are all used for their effects on growth hormone production but work through different mechanisms. GHRH stimulates the pituitary gland to produce growth hormone, while GHRP stimulates the release of growth hormone from the pituitary gland. MK677, on the other hand, mimics the action of ghrelin, a hormone that signals the body to release growth hormone.

With regards to their potency, GHRH and GHRP are generally faster-acting and more potent than MK677 in terms of their ability to increase growth hormone levels.

Conclusion: Can I get taller using MK677?

While MK677 may have some potential benefits for muscle growth, fat loss, and other areas, there is no evidence to suggest that it can increase height in adults. So unfortunately, if you’re hoping to grow a few inches tall, you might have to rely on good old-fashioned genetics!
