MK-677 is a surprising SARM. Surprising because it’s not one at all. So what actually is it, and how does it work? A lot of MK-677 reviews don’t actually make that clear, they just tell you about its potential muscle building benefits.

So what I’m going to do here is give you a balanced MK-677 review. I’ll tell you how it works, how to dose it, how an should MK-677 cycle look, what SARMs you should stack it with, plus also whether all those user reviews read you’ll online are true.

Plus, I’m going to tell you the bad as well. There are side effects to using MK-677, mostly not serious and also potentially one is beneficial to bulking up. But you do need to be aware of them.

On top of all that, I’m going to tell you the best place to buy MK-677, based on my own experiences of experimenting with SARMs (purity is rare but essential).

How Does MK-677 Ibutamoren Work?

MK-677, also called Ibutamoren and Nutrobal, is often referred to as a SARM, a Selective Androgen Receptor Modulator. However, this is completely accurate. It is usually lumped in with SARMs for sale because of the results it produces, and the fact that people stack it with SARMs.

But MK-677 is actually a growth hormone secretagogue that stimulates the ghrelin receptor. To put that in English, it mimics a hormone called ghrelin that is linked to indirectly stimulating muscle growth.

The result of this is increased levels of something called the human growth hormone (HGH) in plasma. Unlike most chemicals that achieve this increase it also doesn’t increase levels of cortisol, which can have terrible side effects.

HGH not only sends messages itself to build muscle and bone density, but it also stimulates higher levels of another hormone called IGF-1 (insulin-like growth factor one), which is a key component of building muscle mass without increasing fat.

Put all that together, and the benefits of MK-677 can be pretty impressive in potential:

  1. Can dramatically increase muscle repair and therefore muscle regeneration and growth
  2. Increases bone density which helps with strength and recovery
  3. Increases appetite which can be brilliant for fueling the packing on of new bulk
  4. MK-677 improves the quality of sleep and potentially some cognitive function
  5. Aids recovery times through faster muscle repair
  6. Can produce significant increases in both muscle mass and density

MK-677 Dosage Advice

Because MK-677 isn’t actually a SARM, it doesn’t interfere with testosterone levels. True SARMs can dramatically drop T levels and cause significant problems which have to be repaired through post cycle therapy (PCT) supplements like Nolvadex and Clomid.

But because MK-677 stimulates higher levels of HGH, it doesn’t interfere with testosterone levels. So on its own, you won’t need a PCT supplement at all.

So you’re safe to dose MK-677 for longer than other SARMs. There are side effects, and so you do have to keep to a cycle with a break between. I’ll talk more about cycling it in a moment.

In terms of dosage, there is much evidence because the studies into using MK-677 are rare and incomplete for humans (it’s still a research chemical, like all SARMs).

But anecdotal evidence from those studies, and bodybuilding forums over the past decade, have suggested a dose of between 10 mg and 30 mg per day is safe. Above this the effects diminish and aren’t worth doing.

Its half-life is reputed to be around a day, so you’ll only need to dose it once. If you’re starting off with the stuff then, your first cycle, I’d be dosing 10 mg for a few weeks, and up it by 5/10 mg halfway through if things are fine.

How Long Should A MK-677 Cycle Be?

SARMs cycles are very subjective. On their own, they can potentially be longer and at a higher dose than when you stack SARMs.

MK-677 isn’t a true SARM, but you should still have a gap between cycles and keep the cycles to a reasonable length.

For your first MK-677 cycle, I would suggest eight weeks followed by an eight-week break. If everything is fine, you can up the dose slightly for your second cycle, and drop the gap between cycles to 6 weeks. Always be cautious, and be very aware of what is happening to your body and mind.


Creating Powerful MK-677 Stacks

The true power of SARMs is in stacking them. Because some can bulk, some can cut, some can build energy and endurance, you have to stack them to get the synergy to push your bodybuilding up to a completely new level.

Because MK-677 doesn’t drop testosterone levels, and the fact it builds muscle and bone density through sending signals to do so, it’s perfect for stacking with bulking SARMs to build those muscles even quicker than they could on their own, and also for building muscle and bone while cutting as well.

A classic bulking stack that uses MK-677 is:

  • 10 mg MK-677 daily
  • 15 mg RAD-140 Testolone daily
  • 5 mg Cardarine daily
  • 10 mg Andarine S-4 daily
  • Cycle length of six weeks
  • Post cycle gap of six weeks
  • PCT supplement definitely needed

Put together, what you’re getting with this potent bulking stack isn’t all-round performance and growth booster.

Rad-140 and S-4 are classic bulking SARMs. They build huge lean muscle in a short space of time. Then you’re using MK-677 to increase those gains, and also to get the messages through to your muscle and bone to grow.

Plus, you’ve got a low dose of Cardarine. Again, it’s not a SARM, it’s a PPAR-Delta modulator. It stimulates protein receptors and glucose production. This boosts energy levels and fuels the muscles, leading to better performance and growth.

This will be suppressive though guys, so really make sure you’ve got Nolvadex to hand. Your first cycle I’d say have Clomid as well, just in case the T level drops are so dramatic that Nolvadex can’t cope.

At the other end of the scale, let’s look at a MK-677 stack for cutting:

  • 15 mg MK-677 daily
  • 20 mg Ostarine daily
  • 10 mg LGD-4033 daily
  • Eight-week cycle
  • 4-6 week post cycle therapy gap
  • You will need a PCT supplement

This SARMs stack uses both Ostarine and LGD-4033 to dramatically cut body fat, but still maintain muscle tone and development even in a calorie deficit.

So you will build some muscle and your tone will develop, and you’ll also lose up to 5% body fat in a single eight-week cycle. Just watch out for the suppression though, because LGD-4033 is one of the most testosterone suppressing SARMs.

My MK-677 Results In One Cycle

So what MK-677 results can you expect in a single cycle?

For me, I experimented with one cycle of just this SARM. I wanted to stack it, because that’s where the power is, but I wanted to see what it did on its own.

I followed the cycle advice I’ve given you in this MK-677 review, and results were impressive. I significantly increased muscle mass and tone. I felt stronger, and I was recovering far quicker by the end of the cycle. It was incredible progress.

I was ravenously hungry and I really had to watch I wasn’t reaching for the junk. You’ll need high-protein foods that fill you up, and fuel your muscles.

But the stacks are where the potency really is. One cycle of MK-677 in a bulking stack is almost too much for some people. You actually have to be careful that growth isn’t too great for even the repairing traits of MK-677 to cope with, it can put stress on your ligaments and bones. so take it steady, but the results are incredible.

MK-677 User Reviews: Can They Be Trusted?

Before I move onto telling you the best place to buy MK-677, I just want to talk you about those user reviews, those MK-677 results you’ll see online.

Those informal MK-677 reviews are often not true. You’ll see generic before and after photos, and they are simply not believable, especially if they are claiming those bodies are gained in one single SARMs cycle.

The truth is guys that you’ve just got to do it yourself. Pick the SARMs, be sensible, eat well, do cardio, make sure you rest up as well. That’s the only way to see if those user reviews are true.

Bests Place To Buy MK-677 revealed

I want to conclude this MK-677 review by telling you the best places to buy MK-677, and other SARMs as well.

I’ve used all of these myself over the years. Why I recommend them is the prices are good, but most importantly they only sell pure SARMs, guaranteed.

The guarantee comes in the fact that they publish current batch lab test reports directly on the website, often on the product page itself. These show they have been independently lab tested by a third party and are 100% pure. That’s the ultimate guarantee, and you should never buy SARMs from anywhere that doesn’t display these guarantees.


First on my list are They used to trade under another name, but have rebranded. They still offer the same high quality SARMs though.

You’ll get free postage, a moneyback guarantee, and the product purity reports are posted right there on the product page.

In terms of pricing, MK-677 in loose powder form will cost $49.99 for a 1000 mg container. In the more convenient but expensive liquid, MK-677 750 mg $49.99.

I’d seriously recommend you stay away from loose powder. You’ll need a micro scale, and SARMs are really difficult to dissolve from a powder, which means you got to deal with consuming the stuff. Although more expensive, the sublingual liquid that you just drip under your tongue is just so simple it’s wonderful.

2. Sarms4You

Second on my list (although none are better than others, each just has a different offering and different pricing), is Sarms 4 You.

Sarms 4 You is based in Europe. All the other recommendations are in America. So if you’re in Europe, these are the company you should be looking to first. You can order from America as well because they do offer free shipping on larger orders, which could be great if you want capsules.

This company only sell capsules and loose powder, no liquid. The capsules are the ultimate in convenience and exact dosing, but they are more expensive.

You’ll get 60 10 mg MK-677 capsules for €74.99. Far cheaper is 1 g of raw powder (delivering a total dose of 1000 mg, which costs just €59.99.

3. Proven Peptides

Proven Peptides are a well-known popular SARMs seller. They only sell sublingual liquid, no powder or capsules

What they sell is incredibly high-quality. It’s little known that nearly all SARMs are made in China and then imported (although this will change soon as China has banned the manufacturer of SARMs).

Proven Peptides won’t have to worry about that though because the SARMs they sell are made in the USA. So if buying locally and buying quality is important, alongside knowing something is safe, then these are the company usually looking at.

Prices are slightly higher though. A 15 mL bottle containing a total dose of 375 mg will cost you $49.99. So more expensive, but these are definitely premium SARMs for people who are taking their safety seriously.

4. Swiss Chems

Last on the list is Swiss Chems. They are not based in Switzerland, they are based in the USA. They only sell capsules of SARMs now, they used to sell liquid but it could be that the Chinese problem is affecting them.

But capsules are incredibly convenient for dosing, although they are more expensive.

Swiss Chems MK-677 capsules are dosed at 10 mg per capsule. 38 capsules cost $85.95. You can lower this price down to $68.76 if you pay with crypto currency though.

Another thing to mention about Swiss Chems is that they are the only SARMs seller I’ve ever found that sell supplements for PCT as well. This is something that most MK-677 reviews never mention.

You have to buy the SARMs, and then look around for somewhere to buy trustworthy Clomid or Nolvadex from as well. But these are available with 100% purity direct from Swiss Chems, meaning you can order your SARMs and PCT supplements at the same time.
