What is MK677?

Ibutamoren, Ibutamoren mesylate, or MK-677 is an over-the-counter, non-peptide, oral active supplement that promotes the secretion of the growth hormone (GH) and increases insulin-like growth factor 1 (IGF-1). It does this by mimicking the action of the hormone ghrelin and binding to one of the ghrelin receptors (GHSR) in the brain. In simpler words, it is a supplement that functions as a growth hormone booster.

How does MK 677 work?

Unlike peptides, which must be injected, Ibutamoren is an orally active supplement which isn’t degraded in the gastrointestinal tract. It can usually be taken up to once per day, generally in a dose of 5 – 25 mg; this elevates IGF-1 levels in the body for 24 hours. Specifically, Ibutamoren (mk-677) functions by increasing the release of growth hormones, including the insulin-like growth factor 1 (IGF-1), elevating the hormones’ plasma levels while leaving the body’s cortisol levels unchanged. It also has some effect in reducing the release of somatostatin, a growth hormone-inhibiting hormone (GHIH), by constraining the signalling of the somatostatin receptor.  (S 1 & 2)

What are the benefits of MK-677?

Ibutamoren has numerous benefits, which have been verified through clinical studies, some of which are ongoing. A regular dosage with the correct medical guidance should see benefits appear in a short time.  Some of the biggest documented benefits include:

  • An increase in lean body mass without changing the total fat mass or levels of visceral fat with mk677 (S 3, 4)
  • An increase in bone mineral density and bone turnover (S 5, 6)
  • As a treatment for growth hormone deficiency, particularly among children (S 7)
  • Improved sleep by increasing sleep REM and overall restive quality (S 8)
  • 677 has shown improved tissue regeneration and wound recovery time (S 9)
  • Fighting aging and performance decline by sustaining/restoring youthful hormone levels (S 10)

A study which aimed to analyse the effects of Australia MK 677 Ibutamoren upon Alzheimer disease concluded that it was, in actuality, ineffective at slowing the rate of progression of the disease (S 11).

What are the side effects of Ibutamoren?

In addition to the benefits of using Ibutamoren MK-677 Australian studies have also examined for any potential side effects. The most frequently recorded side effects of Ibutamoren are shot-term and relate to an increase in appetite, mild lower extremity edema and transient muscle pain (S 12). Some studies have also reported that people with high GH levels have an increased insulin resistance, which could have adverse effects for diabetics. It is also suggested that Th1 dominant people and cancer suffers avoid the use of Ibutamoren because of the potential to worsen conditions (S 13, 14).

  1. Definitely well dosed, I felt that hunger within 30 minutes of my morning dose. Almost a insatiable appetite the first days then just because a nice appetite boost. Especially for those who don’t like breakfast. I felt recovery time improve and I also think it helped a niggling hamstring tendinitis heal quicker. My recommendation is to use a 5 on 2 off weekly routine with this and to have a sip of juice in your mouth then squirt the dose in while still holding the juice. Swallowing both together mitigates the taste greatly

  2. Massive increase in appetite. This can not be understated. I ate kilos of protein and vegetables every day. This does stop after a few days. I suggest to take only on days of training and maybe not on days off to keep fat gains low from overeating on off days. Holding doses in the mouth increasesabsorbtion but remember any food /juice increases insulin which will supress growth hormone secretion. At night 4 hours after food seems the best time to take. This also reduces hunger pangs as your asleep.

  3. I tried mk-677 and it was good, boosted hunger but I only had one bottle so didn’t see much gains in the time. I plan on buying three of them with the next order.

  4. My last order consisted of Mk 677 and LG 4033 this was my first experience with sarms and I must say I was impressed . I noticed an increase in both strength and muscle mass as well as a general feeling of well being . I am 58 years old and was diagnosed with very low test a several years ago and I have been looking for ways to sustain test levels , I am currently on test replacement albeit only low doses that you can get from doctors etc , but being a retired semi professional sports person I have always been health conscious and work out and want to maintain a quality of life for as long as I can . I have been saving my pennies as I would like to try the mass stack as my next cycle of sarms .

  5. Product arrived very promptly. Started to notice visible results after about 3 to 4 weeks of use. Not the most pleasant of taste but so long as the products work that is neither here nor there.

  6. I tried the MK677 and experienced noticeable size and strength gains in 3 weeks. It is a good product.
