Everything You Need To Know About MK-677

Also known as Ibutamoren, MK-677 is often referred to as part of the SARM family, although strictly speaking this is incorrect. Ibutamoren is not a selective androgen receptor modulator but is a compound known as a secretagogue. What this means is that it signals the body to produce or secrete a specific hormone.

Benefits of MK-677

MK-677 makes the body increase the amount of growth hormone it produces, which has many ancillary effects, most of which are related to muscle growth and increased bone density. In medical fields, it was developed to treat frailty in the elderly. In short, the main benefits of ibutamoren are:

  • Increases IGF-1 and growth hormone serum levels
  • Promotes lean muscle mass gain
  • Increases fat oxidation
  • Boosts recovery and healing including bones, tendons, and ligaments
  • Tightens the skin
  • Improves sleep quality

In addition to increases in muscle tissue and a leaner physique, studies suggest that Ibutamoren can produce significant anti-ageing effects, as well as improved bone density and more rapid recovery times.

A single tablet taken daily is designed to release wave after wave of naturally secreted growth hormones.

How Does MK-677 Work?

Ibutamoren is an orally taken drug which once ingested tricks the pituitary gland into working overdrive. The massive boost in GH or growth hormone is what makes it so interesting to the bodybuilding world. Combined with the appropriate diet and exercise regimen, an introduction of Ibutamoren can cause impressive muscle growth alongside much improved fat loss.

Side Effects of MK-677

It’s always worth considering the data when trying to determine whether a drug is right for you. While there has been a reasonable amount of study into Ibutamoren, there hasn’t been a great deal of research into its use as a bodybuilding supplement. With that said, the studies and anecdotal evidence that do exist suggest there is little to fear health-wise.

The most common side-effects experienced with Ibutamoren include slight lethargy, some experience increased appetite, although this isn’t always a negative side-effect for those who need some help gaining weight/bulking.

Although rare, some users have reported headaches and nausea, which would appear to increase in prominence at higher doses.

Because Ibutamoren is an orally taken substance, it’s probably safer than anything you need to take via a needle, which also reduces any hygiene-related risks such as bacteria or infections from unclean syringes or contaminated solutions.

MK-677 is Safe for Women

Ibutamoren is fine to use for both men and women as it doesn’t affect the amount of testosterone or estrogen the body produces. This means that there is zero-risk of specific hormonal imbalances and unwanted side-effects like puffy nipples, heightened aggression or hair loss.

MK-677 Dosage

Ibutamoren works well at lower doses. The average is around 5mg and this is enough to produce numerous GH pulses over the course of a day.

Some users have reported more pronounced effects at higher doses of around the 25mg range, but there is significant anecdotal evidence to suggest a higher dose comes with more ill effects. The users who did report those findings, also said the side effects seemed to diminish after they lowered the dosage.

Ibutamoren stacks well with SARMS and prohormones.
