MK677 10 (Ibutamoren)

What is MK677 10 (Ibutamoren)?

MK677 raises growth hormone from a tablet. It does not suppress your testosterone, so there is no post-cycle protocol, and it will make you hungry.

Also sold as ibutamoren, MK-677 or Nutrobal.

MK-677 works differently from most of this category. It is a growth hormone secretagogue: it tells your pituitary to release growth hormone, the same mechanism as the injectable secretagogues, but in a tablet with a long enough half-life to work once a day. That is why it does not suppress testosterone.

MK677 10 benefits

• Raises growth hormone and IGF-1 from a tablet rather than an injection
• Does not suppress testosterone, because it does not act on androgen receptors
• No post-cycle therapy needed, which is genuinely unusual in this category
• Marked improvement in sleep depth, which is what most users notice first
• Long half-life, so one dose a day is the whole protocol
• 10mg tablets, which is the standard daily dose

MK677 10 dosage

Standard

10 to 25mg per day

Common

10mg, one tablet

Timing

Before bed, which suits the sleep effect

Frequency

Once daily

Half-life

About 24 hours

Run length

8 to 16 weeks

10mg is where most people sit and 25mg is the upper end. Higher doses mostly add water retention and hunger rather than more growth hormone.

Taken before bed because the sleep effect is the most reliable thing about it, and because the lethargy some people get in the first fortnight is then slept through.

Who is MK677 10 for?

People who want growth hormone benefits without injecting, and anyone struggling to eat enough on a bulk. The sleep improvement alone is why a lot of people stay on it.

It is the wrong compound on a cut, where the appetite effect works directly against you. Ipamorelin raises growth hormone without the hunger, if injections are acceptable.

How to use MK677 10

Swallow one tablet with water before bed. It can be taken with or without food. No cycling off is required for hormonal reasons, though most people run it in blocks.
