MK-677 (Ibutamoren), All you need to know

[Billy Sole]

Will it increase height and help in bulking if im 19?

 

[unluckylucky]

keep good notations on height progress with details you could save an important part of the community(teen to late teens even mid twenties all genetics just like life)

 

[Soalian]

What about GH peptides, OP ?

 

[Soalian]

GH peptides are severely underrated here, but I guess they're less convenient to use than oral MK-677.

Yes, they are very effective. But many of those peptides are less affordable than mk + they have to be contained in special conditions and therefore many youngcels cant use them

likely wont help with height at this age but definitely helps with bulking, helped for me personally

Kind of true, but I've been using GHRP-2/CJC-1295 without DAC stack for some time, sometimes the vials were left in a drawer at room temp for like over a week, with no substantial, subjective loss of potency. Ofc it's better to refrigerate.

I didn't get the lethargy and bloating I had from MK-677, though.

 

[WhiteGoodman]

Thanks for the thread OP. Bookmarked!

MK-677 (Ibutamoren) – Results, Clinical Trials & Reviews

ibutamoren (developmental code name MK-677) is an orally-active growth hormone secretagogue and ghrelin receptor agonist being researched as a potential treatment for growth hormone deficiency and sarcopenia​

What Is Ibutamoren (MK-677)?
Ibutamoren (MK-677) is a growth hormone secretagogue and ghrelin receptor agonist.
It increases the endogenous secretion of GH and IGF-1.
A growth hormone secretagogue is simply a substance that signals the pituitary gland in your body to secrete more growth hormone.
MK-677 is orally bioavailable, therefore it can be swallowed (no injections needed).
To date, there have been no viable orally bioavailable alternatives to synthetic human growth hormone injections.
Much like SARMs, it is non-steroidal, but contrary to popular belief, MK-677 is not a SARM in any capacity, despite commonly being thrown into that category.
MK-677 will not negatively affect natural testosterone levels or endocrine function in any capacity at all, as it does not suppress any male sex hormones.
MK-677 has a much longer shelf-life than reconstituted GH, and does not need to be stored in the fridge or freezer to prevent degradation.
Clinical trials are currently assessing how viable of a potential treatment MK-677 is for addressing growth hormone deficiencies, muscle wasting diseases, Osteoporosis and a myriad of other related conditions.


MK-677 Effects

​

- Increases Bone Density​

In a 12 month study conducted on postmenopausal osteoporotic women, 25 mg of MK-677 per day increased bone mineral density and was well tolerated without any significantly concerning side effects.​

In a 2 month randomized, double-blind, parallel, placebo-controlled study on 24 healthy obese men (ages 19-49), 25 mg of MK-677 per day increased markers of bone formation within the first 2 weeks, and increased serum osteocalcin levels at the 2 month mark.​

Predictably, large increases in serum IGF-1 levels were also noted.​

In a clinical study evaluating the changes in serum IGF‐I and markers of bone turnover in 187 elderly adults (65 years or older) lasting 2–9 weeks, dosages of 10-50 mg were administered once daily.​

All treated individuals experienced increased bone turnover, regardless if they were healthy or functionally impaired men or women.​

​

- Builds Muscle​

Growth hormone (GH) can accelerate lipolysis, and has an an anabolic effect in muscle tissue by increasing insulin-like growth factor (IGF)-I and nitrogen retention.​

In a 2 month study on 24 healthy obese men using 25 mg of MK-677 per day, 3 kg of lean muscle mass was gained in the MK-677 treated group compared to the placebo group.​

According to a DEXA scan, total body fat did not change during the study, equating to a gain of 6.62 pounds of muscle in the MK-677 treated group.​

It should be noted that this conclusion has limitations, due to the fact that intracellular water very likely contributed a fair portion of that “fat-free mass” that was gained.​

​

- Increases BMR​

Basal Metabolic Rate (BMR) was increased by MK-677 at 2 weeks of treatment, even after correction for the increase in fat-free mass.​

​

Due to its positive effect on body composition, there is a case to make in regards to MK-677 being a possible treatment for obesity.​

​

- Increases Nitrogen Retention​

Ibutamoren exhibits blatantly anti-catabolic properties, one of which is its ability to retain nitrogen even in a steep caloric deficit.​

Eight healthy volunteers (ages 24–39 yr) were calorically restricted (18 kcal/kg·day) for two 14-day periods.​

During the last 7 days of each diet period, subjects received either oral MK-677 25 mg or placebo once daily.​

MK-677 reversed nitrogen wasting caused by the caloric deficit, suggesting that if these short-term anabolic effects are sustainable, it could be a viable treatment for those experiencing chronic disease, or other muscle wasting catabolic conditions.​

​

- Improves Sleep Quality​

A study with eight young subjects (18-30 years) and six older subjects (65-71 years) found that MK-677 was able to increase REM sleep by as much as 50%​

​

Many anecdotal logs report much deeper sleep as a result of MK-677 usage as well.​

​

- Longevity​

Natural Growth Hormone secretion downregulates with age, consequently lowering serum IGF-1 levels in the body, which results in significant lean muscle catabolism and increased mortality.​

By restoring GH and IGF-1 levels to that of young healthy adults, it is likely that a significant amount of muscle and bone degradation could be prevented entirely.​

In a study conducted on sixty-five healthy men and women ages 60-81, 25 mg MK-677 treatment per day resulted in increases in GH and IGF-1 levels to levels seen in young adults.​

In another study conducted on one hundred sixty‐one hip‐fracture patients aged 65 and older, 25 mg MK-677 treatment per day increased serum IGF‐I levels by 84%.​

Higher levels of IGF-1 are also associated with longer telomere length (a generally accepted marker of aging)​

​

- Improves Immune System​

A study on mice showed that a growth hormone secretagogue could generally duplicate the same enhancement of the immune system observed by treating mice with synthetic GH injections.​

Statistically significant changes in immunological parameters in the young and old mice treated with the growth hormone secretagogue were noted.​

Tumor resistance increased substantially, and there were signs of anti-aging whereby a deficiency in the thymus in mice (a result of aging) was reversed entirely.​

Currently, growth hormone injections are an approved treatment for treating muscle wasting caused by AIDS, and the findings in this study would suggest that a growth hormone secretagogue like MK-677 could fulfill a clinical need for AIDS patients and individuals undergoing chemotherapy and irradiation.​

It would also have the obvious advantage of being orally bioavailable, whereas GH can only be administered via injection.​

​

- Hair Loss Prevention​

IGF-1 has been shown to affect follicular proliferation and differentiation, remodelling of tissue, as well as the hair growth cycle itself.​

More evidence is arising to suggest that IGF-1 plays an important role as a regulator in hair follicle biology.​

It should be noted that patients with growth hormone (GH) deficiency resulting from defective hormone binding with low serum IGF-1 levels exhibit very sparse hair growth.​

Anecdotally, several users of synthetic GH injections and Ibutamoren have reported a faster growth rate of their hair, as well as improved overall hair density.​

​

- Prevention Of Growth Hormone Deficiency​

MK-677 has exhibited the ability to increase serum GH and IGF-1 levels to that of a young healthy adult, thus it was obviously desirable to assess if it could be a potential alternative treatment to growth hormone injections for those diagnosed with growth hormone deficiency.​

In a study conducted on nine severely GH-deficient men ages 17-34 yr who had been treated for GH deficiency with GH during childhood, once daily dosages of 10 or 50 mg MK-677 or placebo were administered.​

10 mg MK-677 increased serum IGF-1 levels by 52% on average, and increased GH levels by 79% on average.​

50 mg MK-677 increased serum IGF-1 levels by 79% on average, and increased GH levels by 82% on average.​

These improvements are indicative of Ibutamoren's potential as an alternative form of treatment for GH deficiency during childhood.​

Benefits Of Higher GH Levels and IGF-1 Levels
Healthy GH and IGF-1 levels support a variety of positive benefits in the body.

As mentioned earlier, these benefits include anti-aging properties, which is why HGH is commonly referred to as the real “fountain of youth.”

GH Benefits

• GH promotes and increases the synthesis of new protein tissues, allowing new muscle to be built
• Metabolizes fat incredibly well, improves complexion
• Has dramatic anti-aging properties
• Increases hair growth (where you want it)
• Improves sleeping patterns (making for fewer unintended awakenings and better REM-stage sleep)
• Produces more energy
• May improve sexual performance
• Increases bone density which prevents injury and helps promote healing
• Can improve the quality and duration of heart and kidneys

IGF-1 Benefits

• IGF-1 supports cellular division (hyperplasia), making it the only hormone that can actually create brand new muscle cells via muscular cell division.
• Supports the repair of nerve damage
• Lowers body fat levels
• Exhibits anti-aging properties by tightening up loose skin
• Aids in the repair of bones, tendons and ligaments.

Limitations

While MK-677 will effectively stimulate the secretion of growth hormone in those with a functioning hypothalamic pituitary adrenal (HPA) axis in most cases, there are certain scenarios in which it is ineffective.

1. Individuals who have a non-functioning hypothalamic pituitary adrenal (HPA) axis
2. Individuals who are unable to secrete growth hormone
3. Individuals who simply do not respond to MK-677 at all
4. Approximately 30% of children with PGHD will not be able to restore healthy GH and IGF-1 levels with MK-677 treatment

MK-677 Dosage
MK-677 exhibits a dose dependent positive effect on serum GH and IGF-1 levels.
The clinical data suggests that Ibutamoren begins exhibiting diminishing returns above and beyond dosages of 25 mg per day.
The remains consistent among the majority of the clinical studies, with almost every trial utilizing a once daily oral dosage of 25 mg of MK-677 to assess Ibutamoren's efficacy relative to placebo.
When comparing high dosages of MK-677 to low dosages, there wasn't a significant difference between GH levels at dosages of 10 mg and 50 mg per day, however, there was a significant difference in serum IGF-1 levels between the 10 mg per day dosing group, and the 50 mg per day dosing group.
In severely GH-deficient men ages 17-34 yr, on average, 10 mg MK-677 increased serum IGF-1 levels by 52%, and increased GH levels by 79%, while 50 mg MK-677 increased serum IGF-1 levels by 79%, and increased GH levels by 82%.

Side Effects
MK-677 will almost undoubtedly greatly increase appetite.
Besides acting as a potent growth hormone secretagogue, MK-677 is also an oral ghrelin mimetic.
Ghrelin is the “hunger hormone” that your stomach secretes in order to regulate your appetite.
By artificially stimulating the secretion of that hormone, the body is tricked into being hungry, even when it wouldn't have been otherwise.
MK-677 has a very significant effect on Ghrelin, more so than any other ghrelin receptor agonist with the exception of GHRP-6.
How MK-677 and GHRP-6 differ is that GHRP-6 is in and out of the body very quickly (half-life of 20 minutes), whereas MK-677 will stimulate ghrelin secretion for several hours, thereby resulting in greatly increased levels of hunger all day long.
While MK-677 has a positive effect on body composition, I don't believe the clinical data takes into account how important diet adherence really is when it comes down to what will get someone in shape.
In almost all cases, having chronic ghrelin secretion being stimulated would make it nearly impossible to stick to a strict caloric deficit in order to reap the true metabolic benefits that Ibutamoren can provide in the first place.
It's easy to see why this compound is recreationally used so often as an appetite stimulant, as the ghrelin secretion properties are incredibly potent.

Lethargy
Though not reported in the clinical data, I can assure you that anything that increases your GH and IGF-1 levels will increase your lethargy.
Regardless if GH/IGF-1 is increased via synthetic gh injections, growth hormone releasing peptides, or growth hormone secretagogues like MK-677, increased levels of lethargy is an expected and common side effect.
Intense Dreams
Dreams (both lucid and non-lucid) are much more common during the REM cycle of sleep.
As sleep affects the regulation of growth hormone (GH), typically, getting a deep and restful sleep is associated with optimal growth hormone secretion, and consequently, more dreaming.
Stimulation of endogenous GH secretion with MK-677 can improve sleep quality, promote the body to enter the REM cycle, and in turn experience more dreams.
Water Retention
A common side effect from elevated GH and IGF-1 levels is water retention.
Expectedly, the most common side effect aside from increased appetite was transient edema and muscle pain in clinical trials.
The muscle pain likely being an indirect side effect caused by intracellular water retention putting increased stress on the joints and muscles.
Increased Blood Pressure
Increased blood pressure is an indirect side effect resulting from edema, which is one of the most common MK-677 side effects.

Elevated Blood Sugar & Reduced Insulin Sensitivity
Although several clinical studies found no change in blood glucose levels, there were a couple studies where MK-677 caused an elevation of fasted blood glucose levels and decreased insulin sensitivity.
GH causes blood sugar levels to rise, which in turn requires the pancreas to work harder to compensate and release insulin to bring blood sugar levels back down to homeostasis.
Chronic GH elevation can create chronic pancreatic stress in certain scenarios, which eventually can result in pancreatic beta cell degeneration, and insulin resistance.
Chronic blood glucose elevation and pancreatic cell degeneration is what eventually leads to Type 2 Diabetes.
Individuals with other lifestyle factors that contribute to insulin resistance as is (excessive carbohydrate intake, holding too much body fat, lack of exercise, etc.), or have genetic predispositions that increase their likelihood of Diabetes, could potentially end up pushing themselves over the brink and become Type 2 Diabetic with MK-677 or synthetic growth hormone usage.

Reactive Hypoglycemia
MK-677 can raise blood glucose levels, which is a mechanism that is autocorrected and regulated by the pancreas in healthy individuals.
In insulin resistant individuals, MK-677 can cause reactive hypoglycemia, whereby sharp spikes in blood sugar can cause an exaggerated level of insulin secretion and glucose uptake into the cells, consequently crashing blood sugar and causing hypoglycemia.
This poor endogenous regulation of blood glucose levels is typically indicative of some degree of insulin resistance in an individual.
Signs and symptoms of reactive hypoglycemia may include hunger, weakness, shakiness, sleepiness, sweating, lightheadedness and anxiety.


Tingly Or Numb Fingers And Hands
This is a common side effect of elevated growth hormone levels, and is commonplace among anecdotal reports on Ibutamoren.

Enhanced Fear In Rats
One study on rats evaluated MK-677's potential to cause enhanced levels of fear.
There is evidence to support that one of the ways ghrelin is modulated is through exposure to stress.
What this study intended to assess specifically was if rats would have a greater likelihood of experiencing fear and posttraumatic stress disorder (PTSD) when their ghrelin levels are artificially raised 24/7 with a ghrelin receptor agonist (MK-677).
So, rats were continuously administered MK-677, and frightened constantly, and their difference in response (MK-677 treated vs non treated) was assessed.
The rats with chronic ghrelin elevation were found to have enhanced fear memory compared to baseline.
This same response has yet to be replicated in human trials, or in anecdotal logs

MK-677 Vs HGH Injections​

The majority of competitive bodybuilders and other performance enhancement seeking athletes view growth hormone as a valuable tool for enhancing their muscle growth and fat loss potential.

However, legitimate GH is simply unaffordable to most.
With a pharmacy-grade kit of GH being upwards of $600-1000 in many instances, it can be extremely cost prohibitive just to use a modest dosage on a daily basis.
With MK-677 exhibiting effects formidable to that of a modest dosage of pure GH in clinical trials, it is easy to see why it has garnered so much attention from those seeking performance enhancement.
MK-677 also has the advantage of being stable in room temperature, orally bioavailable, sustaining elevated IGF-1 levels 24 hours post-ingestion, and works via stimulating natural endogenous GH secretion, as opposed to exogenous synthetic GH injections which will increase serum GH levels irrespective of the body's current endogenous production without a feedback loop to regulate that hormone levels stay within healthy limits.

high quality thread read every word. taking it at night before bed might circumvent the hunger, but it might be an unintentional nightmare intensifier.
imagine taking m677 like this to heightmaxx but then end up as an high inhib ptsd pussy instead

 

[eduardkoopman]

How to counter sides of it? Especially sugar and insuline resistance

I took berberine with it

 

[Roge]

I took berberine with it

Do it have to be some specific dose? I've read that in studies with Metformin they've took 1mg Metformin for every 1g of carbs a day. Or maybe I should take berberine with every meal (4-5 times a day?). Or just 500-1000mg and thats all

It been a long time ago I used it.
So I don't remember the research on it anymore
