MK-677 vs Ipamorelin vs Sermorelin


Human growth hormone (hGH) is a naturally occurring protein hormone with numerous functions in the aging adult. Growth hormone/IGF-1 deficiency causes decreased muscle and bone mass. In addition, fat gain and decreased strength and energy for exercise can also occur. To regain those youthful HGH levels, your pituitary glands, once stimulated, will restart HGH production. MK-677, Sermorelin, and Ipamorelin come into play here.

Ibutamoren is also known as MK-677. It increases the body’s natural ability to secrete growth hormone (GH) and insulin-like growth factor 1. Its main advantages include increased bone density and muscle mass and anti-aging properties. Additionally, better sleep, sharpened memory, and a boosted immune system are also benefits of this drug.

Ibutamoren MK-677 can help you strengthen your muscles. Long-term use has resulted in an increase in muscle mass and bone mineral density. Increase your training level and performance by increasing your GH secretagogue. In addition, your bone mineral density can also improve with this compound.


  • Raised IGF-1 levels in as little as two weeks.
  • Longer REM sleep and significantly shorter sleep latency.
  • Muscle mass is now more fat-free.
  • Reduce the percentage of body fat you have.
  • Bones that are stronger
  • Increased endurance.
  • Nitrogen wasting is being reversed.
  • High levels of nitrogen in the body.

Possible Side Effects

  • Retention of water
  • High blood sugar levels
  • Bloating
  • Feelings of sluggishness
  • Anxiety
  • Headache
  • Excessive appetite
  • Decreased insulin sensitivity


Ipamorelin is a new and exciting peptide in the growth factor family. Further, ipamorelin is one of the safest GHRPs. It is a secretagogue and also a Ghrelin receptor agonist. Thus, it promotes secretion from cells in the stomach. It is also important in appetite regulation and food intake). Ipamorelin is a third generation GHRP that is one of the cleanest of the GHRPs.


  • Overall increased energy
  • Reduced body fat
  • Reduced body fat
  • Greater collagen production
  • Greater lean muscle mass
  • Aids in the repair of cartilage and nerves
  • Increased cellular repair and regeneration
  • Better sleep
  • IGF-1 production has increased (insulin growth factor hormone)
  • Increases bone mineral content
  • Increases bone mineral content

Possible Side Effects

  • Headache/lightheadedness
  • Retention of water
  • Numbness in the limbs
  • Tiredness
  • Decreased Sensitivity to insulin
  • Carpal tunnel syndrome symptoms


Sermorelin was invented in the 1970s. It is a 29-amino acid peptide. Its primary function is to stimulate the pituitary gland’s natural production of hGH.

Sermorelin is a safe and effective drug. This stimulates and increases your body’s production of human growth hormone (HGH).

Sermorelin is typically used in children with growth hormone deficiency. However, adults can use this at the discretion of a treating physician.


  • Lean muscle mass has increased.
  • Influence on the immune system that is beneficial.
  • Natural sleep patterns that are more beneficial are becoming more prevalent. HGH releases in excess during deep sleep.

Possible Side Effects

  • Swallowing Difficulties
  • Itching
  • Taste Perception Modifications
  • Dizziness
  • Flushing
  • Tiredness
  • Headache
  • Vomiting
  • Hives
  • Issues that are stalling

How the Body Controls Growth Hormones

The pituitary cells produce growth hormones. Every few hours, the somatotrophs release a burst of hGH. Two hormones produced in the hypothalamus are primarily responsible for growth hormone regulation. GHRH and somatostatin (growth hormone inhibiting hormone) are peptide hormones (GHIH). Ghrelin is a third regulatory hormone produced in the stomach. This binds to growth hormone secretagogue receptors to stimulate growth hormone secretion.

Blood sugar levels influence the release of GHRH and GHIH . When blood sugar levels are low, the hypothalamus releases GHRH,. Thus it signals the pituitary to release growth hormone!

What Can Cause a Growth Hormone Decline?

Decreased growth hormone secretion corresponds to decreased GHRH/ghrelin secretion. In addition, increased somatostatin secretion can also occur from this. Both of which are sometimes seen as a result of aging. High blood sugar, obesity, hypogonadism (low testosterone), and high cortisol are all growth hormone inhibitors. In addition, overweight and obese people are more likely to have suppressed growth hormone secretion.

Final Thoughts

Ibutamoren MK-677 is safely absorbed and remains active. Amino acid levels aid in the conversion of protein to energy. Additionally, enteroendocrine cells in our stomach produce the hormone ghrelin. Thus, when we are hungry, the hormone ghrelin rises. Ghrelin levels normally decrease when we eat. One can treat muscle wasting and obesity without side effects by using Ibutamoren. We even get the benefit of better sleep.

When we reach puberty, our immune system reaches its peak. However, this does not mean that our GH deficiency has to stop functioning or growing. The activation of the ghrelin receptor will aid in the prevention of muscle wasting and weakness. This will pave the way for a healthier, younger body free of growth hormone deficiency. Ghrelin receptors help our proteins by converting them into energy, which is critical. There have been no reported side effects from using this product.
