What is Ostarine?
Ostarine (MK-2866, also called enobosarm or GTx-024) is a nonsteroidal SARM first developed by GTx Inc. It binds the androgen receptor, but its structure isn’t based on testosterone, and in lab models it acts mainly on muscle and bone with much less activity in tissues like the prostate.
It’s the most studied compound in its class. Ostarine went through several human trials, yet it has never been approved as a medicine anywhere, and it sits on the WADA prohibited list.

Ostarine in published research
The best-known study is a phase 2 trial by Dobs and colleagues, published in The Lancet Oncology in 2013. It tested enobosarm in 159 patients with cancer-related muscle wasting and reported increases in lean body mass compared with placebo.
Earlier rodent work showed that ostarine binds the androgen receptor with high affinity and builds muscle and bone tissue with little effect on prostate weight. That tissue selectivity is why it’s still a reference compound in SARM research.

Weighing and handling Ostarine powder
Buying Ostarine as a powder gives you full control. Weigh out exactly what your protocol calls for, make up your own solutions, or encapsulate it yourself.
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 Ostarine powder
To make a stock solution, decide on the final volume and concentration first. For 30mL at 10mg/mL you’d weigh 300mg of Ostarine, 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.
Ostarine quality and testing
Every batch of Ostarine is checked with liquid chromatography-mass spectrometry (LC-MS) before it goes on sale. LC-MS separates a sample into its parts and identifies each one by mass, so it confirms what the compound is and how much of the sample it makes up. The current batch tested 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 Ostarine
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 Ostarine powder
What can I dissolve Ostarine 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.
