MK-677 (Ibutamoren) Review: Benefits, Results, Dosage & Cycle

What Is MK677?

MK677, also known as Ibutamoren, is a highly potent and orally active growth hormone secretagogue. It works by mimicking the ghrelin receptor, which is not something many compounds are capable of.

This compound has become extremely popular because it can boost both growth hormone (GH) and insulin-like growth factor (IGF1). Both of these play a role in functions such as muscle growth, recovery, and cell regeneration.

Because of these unique benefits, it's widely used amongst bodybuilders and other athletes to maximize performance.

Keep in mind that MK677 (Ibutamoren) is an investigational drug that has not been approved for consumption.

We don't recommend using it; we simply provide you with information gathered from clinical data and anecdotal experiences.

Is MK 677 A SARM?

Many people continue to ask us:

Is MK 677 a SARM?

The answer is no; it's not. Ibutamoren should not be mistaken for a selective androgen receptor modulator (SARM).

Many vendors promote this compound as one, but it is a GH secretagogue meaning it works differently.

MK 677 Benefits and Results

MK 677 is used because it has been scientifically shown to increase growth hormone (GH) and insulin-like growth factor (IGF1).

Both GH and IGF1 are crucial hormones that, when increased, lead to numerous benefits; here's a breakdown of what to expect.

Accelerated Recovery

Growth hormone helps with repairing muscle tissue and other cells. It also impacts the skin, metabolism, and fat loss.

When GH is increased, it is going to accelerate these processes. As an athlete, that's going to have significant benefits. You'll recover faster, which allows you to handle more workload during exercise.

According to users that have experimented with this compound, it takes several weeks to notice this effect.

Enhanced Muscle Growth

As previously mentioned, MK 677 is said to boost GH and IGF-1. Both these hormones play a role in muscle growth, meaning you're going to notice an increase in fat free mass.

Primarily growth hormone has shown to increase muscle mass and strength, making it useful for athletes.

The muscle-building capabilities of Ibutamoren have also been reported in several clinical studies.

Increased REM Sleep

Another very noticeable benefit is that MK 677 increases REM sleep. In adults, Ibutamoren increased REM sleep by up to 50%.

Taking this compound will significantly enhance sleep quality; many anecdotal experiences also back this.

Of course, getting enough sleep and rest is crucial. It's going to help with productivity, recovery, muscle growth, and more.

MK 677 Dosage & Cycle Information

It's crucial to nail down the proper MK 677 dosage in order to reap the benefits.

When we look at the scientific data, an MK677 dosage of 20 to 25mg per day seems to work optimally. At that dosage, it appears to be the most effective at increasing IGF-1 and GH.

After going through the clinical data, we've also taken a look at several dozens of anecdotal experiences to see what dosage is most common.

We found that it's taken at dosages of between 10 to 30mg per day. But, the majority of the users seem to take 20 to 30mg per day. That's when they say the effects are optimal, which is in line with the scientific data.

It's worth mentioning that the higher the dose, the more likely one is to experience side effects (we'll talk about those later).

MK-677 is typically used for cycles of 8 to 16 weeks. We see the majority aim for more extended periods of 3 to 4 months due to the effects of this compound.

It's often stacked with SARMs such as RAD140 or LGD4033 to help the user increase lean muscle mass, strength, and performance even further.

If you're going to stack Ibutamoren with SARMs, you're going to need to stock up on a post cycle therapy to use after the cycle.

In that case, we recommend getting Rebirth PCT, the most effective PCT supplement on the market.

What Is The Half-life Of MK 677 (Ibutamoren)?

The half-life of MK 677 is 24 hours. Because of the long half-life, most users dose it once per day to maintain stable levels.

When Should You Take MK 677?

MK 677 is typically taken once per day in the morning with breakfast or in the evening before bed. Since it causes an increase in hunger, many users prefer to take it before going to sleep.

MK 677 Safety & Side Effects

Many wonder whether or not MK 677 is safe, and the answer to that is no.

It isn't safe because there is too little information on it. We don't know what kind of impact it has on your long-term health.

MK 677 also does cause side effects, and we've seen many users report adverse effects from taking it.

Here's a list of the side effects one could run into:


Edema (Water retention)

Joint and muscle pain

Increased appetite and hunger

Reduced insulin sensitivity

Most of these side effects are also mentioned in the scientific literature, meaning there's a high chance of experiencing them.

It's also important to note that Ibutamoren doesn't interfere with the endocrine system, meaning it doesn't touch your hormones. That means that post cycle therapy is not required when taken individually.

If you're planning on stacking it with SARMs, you do need post cycle therapy.

We don't know what kind of impact and side effects MK 677 has for the long term. That's one of the main reasons we recommend steering clear from it.

Stacking MK 677 With Ecdysterone

Over the past few months, the combination of MK 677 stacked with Ecdysterone has become quite popular.

The reason for this is that this combination significantly enhances lean muscle mass and strength while not suppressing the hormones.

Because there's no suppression, you won't have to worry about taking a PCT.

Both are taken for more extended periods, which drastically enhances body composition.

Definitely try out the combination of these two, as we've seen mind-blowing results. Remember, there's no hormonal suppression with the two, meaning you can simply stop taking them once you've finished the cycle.
