MK 677 for Height Growth: Does It Work?

Last updated on January 4th, 2024 at 07:53 am

Many people see height as an important part of their self-confidence and self-image. Some feel perfectly happy being on the shorter side. But others wish they could gain a few more inches in height. This has led some to look into products claiming to increase height, including a drug called MK 677.

But does MK 677 really help you grow taller? Let’s explore what studies show about this drug’s effects on height and whether it seems worthwhile for those seeking to become taller.

What is MK 677

MK 677 is a synthetic drug that stimulates the pituitary gland to release more growth hormone. It was initially researched to treat growth issues in children. MK 677 has also been used experimentally to treat conditions like muscle loss, weak bones, and obesity.

This drug is taken by mouth in tablet or liquid form. It is considered a research chemical, meaning regulatory agencies have not approved MK 677 for medical use yet. But some athletes and bodybuilders use it off-label thinking it might build more muscle mass and strength.

The key point is that MK 677 aims to raise growth hormone levels in the body. Let’s examine what impact that may or may not have on height.

What does MK677 do?

The main mechanism of action of MK 677 is that it mimics the hormone ghrelin. Ghrelin is the “hunger hormone” that signals hunger to the brain. It also acts on the pituitary gland and other tissues to stimulate growth hormone release.

By mimicking ghrelin, MK 677 can pulse growth hormone secretion, leading to:

  • Increased IGF-1 (insulin-like growth factor 1) production – IGF-1 plays a key role in childhood growth and continues to have anabolic effects in adults.
  • Boosted protein synthesis – Growth hormone is critical for building muscle mass. MK 677 may help build lean tissue.
  • Enhanced bone mineral density – Growth hormone has been shown to improve bone health. MK 677 may help strengthen bones.
  • More restful sleep – Natural growth hormone secretion increases during sleep. MK 677 may enhance this effect.

So in summary, by stimulating growth hormone and IGF-1, MK 677 creates an anabolic (muscle-building) environment in the body and enhances other processes like bone growth. This has made it popular not just for height but for bodybuilding and anti-aging.

Can we use MK 677 for height Growth?

Based on its growth hormone-boosting effects, MK 677 has been used in attempts to increase height. But what does the research actually say about MK 677 for height growth?

Unfortunately, there are no human studies looking specifically at MK 677 and increased height in adults. However, we can glean insights from other research:

  • In children and adolescents with growth hormone deficiency, MK 677 has been shown to increase growth velocity and IGF-1 levels, leading to increased height.
  • In one study on overweight adults, MK 677 increased IGF-1 levels but did not increase height over the 12-month trial. However, the participants were not seeking a height increase.
  • Growth hormone therapy has been shown to increase the speed of growth in children with growth hormone deficiency. But it does not seem to impact the final adult height potential.
  • The growth plates in bones eventually fuse and halt vertical growth. This generally occurs between ages 16-18 in females and 18-21 in males. After plate fusion, boosting growth hormone is unlikely to increase height.

So while MK 677 may help children reach their natural height potential faster, the evidence does not indicate it can surpass genetic height or promote height growth in adults with fused growth plates.

Can MK677 Make You Taller?

Based on the lack of strong evidence, MK 677 on its own is unlikely to make adults taller once their growth plates have closed. The only proven way to significantly increase adult height that exceeds genetic potential is through painful and expensive leg-lengthening surgeries.

However, some people insist MK 677 has allowed them to grow taller despite having finished puberty. There are a few potential reasons for these perceived height changes:

  • Correcting growth hormone deficiency – If someone has a growth hormone deficiency, MK 677 may help them reach their proper height.
  • Improving posture – Some report MK 677 helps strengthen core muscles, reducing slouching and improving posture/height.
  • Enhanced bone density – MK 677 may lead to small increases in the thickness/length of bones. But likely not enough to substantially increase standing height.
  • Fluid retention – Growth hormone can increase fluid retention, which may temporarily influence perceived height.

So while small posture/bone changes from MK 677 are possible in some cases, expectations need to be realistic. Gaining multiple permanent inches in height from MK 677 after growth plate fusion is unlikely. The hype sometimes exceeds the realistic effects.

What do the Studies Say

Very few clinical trials have examined MK 677 specifically for increasing height in adults. Here is a brief overview of the relevant research:

Pediatric Growth Hormone Deficiency

  • A 2004 study had children with confirmed growth hormone deficiency take MK 677 daily for a year. The MK 677 group increased their growth velocity from 4 cm to 7.5 cm on average. This demonstrated MK 677 helped the children better reach their genetically predetermined height.

Idiopathic Short Stature

  • Children with idiopathic short stature took either MK 677 or a placebo for 24 months in a 2015 randomized controlled trial. The MK 677 group increased their IGF-1 levels and had a slightly accelerated growth velocity compared to placebo. However, MK 677 treatment did not substantially increase final adult height predictions.


  • A 2001 study looked at MK 677 effects on 24 adults with obesity for 12 months. In the end, researchers found no significant change in height in either the treatment or placebo group. This suggests MK 677 does not affect height in adults with fused growth plates.

In summary, MK 677 may help children reach their natural peak height faster but does not seem to increase height beyond genetic limits. While some adults insist MK 677 has made them taller, there is currently no solid scientific research demonstrating MK 677 increases adult height. More large-scale, placebo-controlled trials are needed.

Can You Benefit?

If you’re considering MK 677 to become taller, assessing your age and growth plates is important:

  • Pre-puberty – MK 677 can likely help increase growth velocity and help achieve natural height potential faster. Dosing would need to be carefully managed by a doctor.
  • During puberty – If growth seems to be stagnating before growth plates fuse, MK 677 may support reaching full height predictions. Again, physician monitoring is advised.
  • Post-puberty – Once growth plates have fused, the probability of a significant height increase from MK 677 is very low. Small posture/bone density changes may occur in some.

Health risks also need to be weighed against potential benefits. Long-term safety data in healthy populations is lacking. And artificially raising growth hormones could potentially impact insulin, blood sugar, and other hormones.

Thorough medical checkups are a must if trying MK 677 for any purpose. Radiologic imaging would confirm the growth plate status. And bloodwork is necessary to rule out deficiencies contributing to short stature.

In many cases, learning to embrace one’s height is more productive than trying risky, experimental drugs. But if the benefits seem to outweigh the risks for your situation, MK 677 could be cautiously considered. Managing expectations is key.

Long-Term Use Side Effects

What are the risks of using MK 677 long-term in hopes of increasing height? Some potential adverse effects include:

  • Numbness/tingling – Carpal tunnel syndrome symptoms are possible due to fluid retention impacting nerves.
  • Blood sugar changes – Growth hormone can raise blood glucose levels. Those with diabetes may need medication adjustments.
  • Joint pain – Some users report sore joints, possibly from growth hormone-increasing bone thickness.
  • Water retention – Swelling in the hands and feet can occur, along with facial bloating. This may be mistaken for height gain.
  • Liver strain – High IGF-1 levels may stress the liver. Liver enzymes should be monitored.
  • Gynecomastia – Growth hormone elevation could potentially cause breast tissue growth in men. But this is less common with MK 677 than testosterone-boosting supplements.
  • Cardiac effects – Long-term use may thicken heart muscle. Those with heart conditions need caution.
  • Dependency – Since it alters hormone pathways, MK 677 can cause dependence where natural growth hormone production is reduced. This could require slow tapering off cycles.

Using the lowest effective dose, monitoring health markers, and cycling on/off can help minimize adverse effects that may emerge with prolonged MK 677 use. Of course, the best way to avoid side effects is not taking MK 677 at all.

Which is better for height growth: MK 677 or HGH shots?

For those set on using a growth hormone-based compound to increase their height, two options are MK 677 or actual injectable growth hormone. Which is better? Here is a comparison:

  • Convenience – MK 677 is taken orally while HGH must be injected subcutaneously. Most will find MK 677 more convenient.
  • Cost – Pharmaceutical HGH is extremely expensive, costing thousands per month. MK 677 is far more affordable for the average consumer.
  • Side effects – Both can cause similar side effects like water retention, joint pain, and blood sugar changes. However, injected HGH may be more likely to cause dependency.
  • Strength – Injectable HGH is bioidentical to what the pituitary gland produces. HGH may generate higher IGF-1 spikes than MK 677’s pulsatile release.
  • Legality – MK 677 is sold as a research chemical, while HGH is a controlled substance requiring a prescription. HGH illegal distribution risks are higher.

For height enhancement, HGH injections are more “powerful” in theory due to higher peak blood values. But convenience and affordability make MK 677 the more realistic option for most seeking height growth past one’s genetic limit. Of course, neither product can work miracles once growth plates have fused.

Frequently Asked Questions

Is MK 677 FDA approved?

No, MK 677 does not have FDA approval for medical use. It is sold as a research chemical without oversight on purity or quality standards.

Do you need PCT after MK 677?

Because it does not directly impact testosterone or other hormones, post-cycle therapy is generally not required after stopping MK 677.

Does MK 677 cause Cancer?

There are no studies showing MK 677 itself causes cancer.

Can I take MK 677 with other SARMs?

Yes, it’s fairly common for MK 677 to be stacked with SARMs like Ligandrol or RAD 140.

At what age do growth plates fuse?

Growth plates in the long bones typically fuse by ages 16-18 in females and 18-21 in males. However, the fusing process is gradual and Exact timing can vary among individuals based on genetics and environmental factors. Only X-rays can confirm full fusion.

Bottom Line

Countless people wish they could be taller. This has driven some to experiment with MK 677 to unlock extra height potential. However, the evidence is lacking that MK 677 can substantially increase adult height after growth plate fusion. Small posture and bone density changes are possible in some users, but unrealistic expectations need to be avoided.

MK 677 is better studied for uses like muscle building, bone health, and improving growth deficiency in children.

While tempting testimonials exist, MK 677 for adult height growth remains scientifically unproven. Those considering using it should weigh the substantial risks versus the improbable rewards. But learning self-acceptance regardless of one’s stature ultimately proves far more rewarding. For a reliable source, explore options to safely purchase peptides for your health journey.
