MK-677 (Ibutamoren) 10mgs x 60 Tablets

What is MK-677?

MK-677, also called Ibutamoren, comes as a tablet rather than an injection.

It is a growth hormone secretagogue, meaning it triggers the release of a hormone. It acts like ghrelin, a hormone that binds to the ghrelin receptor in the brain.

MK-677 is not a SARM (selective androgen receptor modulator), since it works through the ghrelin receptor instead.

What researchers study it for

• Growth hormone release. Researchers study how it raises GH (growth hormone) and IGF-1 levels.
• Ghrelin receptor activity. Studies look at how it binds to the ghrelin receptor in the brain.
• Muscle tissue. Labs study how higher GH and IGF-1 levels affect muscle cells.
• Fat breakdown. Researchers study its effect on fat oxidation, the way the body breaks down fat for energy.
• Sleep patterns. Some studies also look at its effect on sleep patterns.

What you get

One bottle of 60 tablets, each holding 10 mg of MK-677.

How to store it

What else you need

Nothing. The tablets are ready to use, with no powder to mix and no needle. Labs that study growth hormone pathways often compare MK-677 with peptides such as Ipamorelin and CJC-1295 with Ipamorelin. See more on our MK-677 Canada page.

Common questions

Is MK-677 the same as Ibutamoren?

Yes. MK-677 is the lab code and Ibutamoren is the chemical name, so both refer to the same compound.

Is MK-677 a SARM?

No. SARMs bind the androgen receptor, while MK-677 binds the ghrelin receptor. Our SARMs page lists the SARMs we stock, such as Ostarine (MK-2866) and LGD-4033 (Ligandrol).

How much is in one bottle?

60 tablets at 10 mg each, for 600 mg in total.

Is it tested?

Yes. Every batch is quality tested before we list it.

Can people take MK-677?

No. It is sold for lab research only and is not approved as a medicine in Canada.
