What is Ibutamoren?
Ibutamoren (MK-677) is an orally active, nonpeptide growth hormone secretagogue developed by Merck. It mimics ghrelin at the GHSR receptor, raising growth hormone and IGF-1. It’s often sold next to SARMs but isn’t one.
It was never approved as a medicine and is on the WADA prohibited list.

Ibutamoren in published research
Nass and colleagues ran a two-year trial in healthy older adults (Annals of Internal Medicine, 2008). MK-677 raised GH and IGF-1 to levels seen in young adults and increased fat-free mass, with rises in fasting glucose noted.
Earlier Merck studies by Chapman and colleagues described its effects on GH pulsatility.

Weighing and handling Ibutamoren powder
Loose powder is the most flexible way to buy Ibutamoren. You can weigh any amount you need, dissolve it in your own solvent, or fill your own capsules. It’s also the cheapest format per milligram.
For small amounts you’ll want a scale that reads to at least 0.01g, and ideally 0.001g. Our digital scale and micro scoops make it easier to get consistent measurements. Weigh onto clean weighing paper, and close the bag or jar straight after so the powder doesn’t pick up moisture.
Making a solution from Ibutamoren powder
To make a stock solution, decide on the final volume and concentration first. For 30mL at 10mg/mL you’d weigh 300mg of Ibutamoren, dissolve it in about 25mL of solvent, then top up to exactly 30mL.
Check the compound’s solubility in your chosen solvent before you start, and try a small test amount first. Store the finished solution in a labelled glass bottle.
Purity testing for Ibutamoren
We test each batch of Ibutamoren by LC-MS, which pairs liquid chromatography with mass spectrometry. The chromatography splits the sample into its components and the mass spectrometer identifies them, which tells you both identity and purity. This batch came in at 99% or higher.
Small differences between batches are normal, so write the batch number from the label into your records. If something looks wrong when your order arrives, like discoloured powder or a cloudy solution, set it aside and don’t use it.
Storing your Ibutamoren
Keep it in a cool, dry place away from direct sunlight. Use a clean, dry scoop each time, and reseal the container straight away. Label anything you decant with the compound, amount and date, and keep it out of reach of children and pets.
Common questions about the Ibutamoren powder
What can I dissolve Ibutamoren powder in?
That depends on the compound’s solubility and your protocol. Check the solubility data for your solvent first, and test a small amount before making up a full batch.
What scale do I need?
One that reads to 0.01g at minimum, and 0.001g for very small amounts. Our pocket scale reads to 0.01g.
