MK-677: dosing, timing and what to expect

An orally active, non-peptide ghrelin receptor agonist. Notable for being oral — no injection — and for producing sustained 24-hour elevations in GH and IGF-1.

Also known as Ibutamoren, Nutrobal

Quick reference. Everything you need to run MK-677 — dosing, frequency, reconstitution math for the vial sizes people actually buy, and what it stacks with. For anything specific to your situation, ask the Guru.

MK-677 quick start

Route
Oral
Typical dose
10–25 mg
Frequency
Once daily, usually at night
Half-life
About 4–6 hours, but effects on IGF-1 persist across 24 h.
Cycle
8–16 weeks with glucose monitoring.
These are the numbers people actually run, drawn from the published record and from what the community has settled on over time. Educational reference, not medical advice — a starting point to work from, and one you can adjust as you learn how you respond.

What people actually run

Popular for being oral. Community is well aware of the water retention, appetite and glucose trade-offs.

This is accumulated community practice — years of real-world use across a large number of people, converging on numbers that work. It is not a controlled trial, and for most compounds here no such trial exists or is ever likely to. That makes this the most reliable dosing signal available, and it is a good deal better than guessing.

What to expect

Most people tolerate MK-677 well. Here is what is worth knowing going in, so nothing catches you by surprise.

Significant water retention, marked appetite increase, and lethargy are common. Reliably raises fasting blood glucose and lowers insulin sensitivity — a real concern for long runs. Banned by WADA.

Known interactions

Interactions involving MK-677's drug class that DoseIQ screens for. Each one cites where it comes from — an FDA label section or the published record — because an interaction warning you can't trace is just noise.

Caution GH peptides push blood sugar against your diabetes medication

Growth hormone raises glucose and insulin resistance — it works directly against glucose-lowering medication.

What to do: Fasting glucose and HbA1c are worth tracking; medication doses sometimes need adjusting. Your prescriber should know GH peptides are in the picture.

DoseIQ screens your whole protocol against these rules automatically — every compound, prescription and supplement you track, cross-checked as you add them. Serious flags are always free.

Preparing it

MK-677 does not need reconstituting — it comes ready to use. Not applicable — oral capsule or liquid.
