Overview

Ibutamoren, code MK-677, is an oral compound that mimics the hunger hormone ghrelin and makes the pituitary release growth hormone. It is not a SARM, though it is often sold beside them.

This listing is Zionova MK 677 (Ibutamoren), photographed as we ship it and priced in Canadian dollars.

How it works

Ibutamoren activates the ghrelin receptor, raising growth hormone and IGF-1 for most of the day after one oral dose. It also increases appetite and can reduce insulin sensitivity.

Clinical reference

There is no approved dose. Clinical studies in older adults and growth-hormone-deficient patients used 25 mg a day.

Reference information from product labels and clinical literature only. It is not a recommendation or dosing advice for you; any use should be set and monitored by a doctor.

Measuring calculator

Type the amount from your prescription or clinician; the calculator only converts it. It does not suggest how much to take.

Combinations and interactions

  • Raises blood sugar, which matters for anyone on diabetes medicines.
  • Its effect on IGF-1 adds to that of growth hormone or other secretagogues.

Risks and side effects

  • Blood sugar. Higher fasting glucose and insulin resistance.
  • Appetite and fluid. Increased hunger and mild water retention.
  • Heart failure concerns. A trial was stopped early over heart-failure signals in a frail population.

Do not use it if you are under 18, pregnant, have diabetes, heart failure or active cancer.

Bloodwork to discuss with your doctor

  • Fasting glucose and HbA1c
  • IGF-1
