MK 677 (Ibutamoren): Results, Dosage, & More (Update 2020)

Ibutamoren, otherwise known as MK 677, is a research chemical that increases human growth hormone (HGH) in the body.

While it was initially developed to treat growth hormone deficiency, many bodybuilders have started using MK 677 to build muscle and recover faster.

MK 677 shows tremendous promise to help users build muscle, recover faster, increase bone density, improve sleep quality, and more.

In this article we will cover the clinical research regarding Ibutamoren, exploring potential dosages, benefits, cycle results, and more.

What is MK 677 (Ibutamoren)?

mk 677 ibutamoren chemical structure

Ibutamoren, often referred to by its research name MK-677, is often grouped together with SARMs, although technically it isn’t a SARM.

Rather, MK 677 is a ghrelin receptor agonist, and a growth hormone secretagogue, which means that it increases HGH in users.

Initially, Ibutamoren was developed as a potential treatment for children and elderly people suffering from growth hormone deficiencies. [R]

That being said, bodybuilders quickly discovered that if a healthy person takes MK 677, they will experience rapid muscle growth and recovery.

MK 677 Benefits

While more clinical research should be done on the benefits and long term side effects of MK 677, there’s a lot of anecdotal evidence out there.

Many people use MK 677 for bodybuilding, even though it isn’t technically approved for human use (yet)—and they report a number of effects.

Here are some benefits of MK 677:

  • Increased Growth Hormone
  • Improved Sleep Quality
  • Faster Recovery Post-Workout
  • Enhanced Muscle Growth
  • Increased Bone Density
  • Better Immune System Function

Because Ibutamoren (MK677) increases human growth hormone (HGH) in users, they can expect all the benefits that come from having more of it.

This includes more muscle growth, better sleep quality, faster healing and recovery after the gym, and of course, higher growth hormone levels.

MK 677 Results

Because MK-677 increases growth hormone in users who take it, users can expect to rapidly build muscle, far faster than you could naturally.

Many of the MK 677 results reported on Reddit involve users gaining very large amounts of muscle, and radically transforming their physiques.

In fact, many bodybuilding cycle logs report gaining over 10-15 pounds of muscle from one 12 week cycle of Ibutamoren (MK-677).

Users in particular who have a hard time sleeping or eating enough to bulk up will benefit a lot from MK 677, as it’s a phenomenal bulking compound.

Dosage & Cycle Guidelines

Even a small dose of MK 677 has a very positive effect on growth hormone levels, overall muscle growth, REM sleep quality, and much more.

However, the most common MK-677 dose is 25 mg per day. That being said, the more you take, up to a point, the more benefits you will likely get.

Here are the anecdotal MK 677 dosage guidelines:

  • Beginner: 10 mg per day
  • Intermediate: 25 mg per day
  • Advanced: 50 mg per day

Studies have shown that taking 10 mg vs 50 mg per day of MK 677 doesn’t have a significant difference on growth hormone, but it does have a significant increase on IGF-1. [R]

This means that, if your primary concern is growth hormone increase, a moderate dosage of 10-25 mg per day of MK 677 would be just fine.

Liquid SARMs and research chemicals are often dosed in mg/ml, so taking 25 mg of MK 677 is equal to one full dropper of MK-677 from Science Bio.

Bulking & Cutting Stacks

MK677 is a phenomenal bulking SARM and is often stacked with other SARMs, such as RAD 140 or Ligandrol, to bulk up faster.

Sample Bulking StackSample Cutting Stack
MK 677 – 50 mg per dayMK 677 – 25 mg per day
RAD 140 – 15 mg per dayOstarine – 25 mg per day
YK11 – 10 mg per dayAndarine – 50 mg per day

Because MK-677 increases growth hormone, it’s primarily best for a bulking stack, however it can also be used to retain lean muscle mass while cutting.

Users may choose to combine this research drug with a SARMs such as Ostarine or Cardarine for cutting, and Ligandrol or RAD 140 for bulking.

Potential Side Effects

Many studies have shown that even long-term usage of MK-677 is generally well tolerated, without any seriously concerning side effects [R].

That being said, more research should be done on the long-term side effects of MK-677, and it still may have some shorter term side effects, too.

Here are some potential MK 677 side effects:

  • Increased Appetite
  • Fatigue & Lethargy
  • Tingly Fingers
  • Higher Fear Sensitivity
  • Intense Dreams

Ibutamoren is also known for causing increased water retention, which is a common side effect of increased HGH levels—this makes it more suited towards bulking than cutting.
