The same compound comes in other formats too: Andarine liquid, Andarine gel packs and Andarine capsules. See all SARM powders for more options in this format.
What is Andarine?
Andarine (S-4, also GTx-007) is one of the first nonsteroidal SARMs, developed by GTx Inc. alongside ostarine. It’s a partial agonist at the androgen receptor, and in rats it built muscle and bone while having much less effect on the prostate.
Development stopped before it reached late clinical trials. It’s on the WADA prohibited list.

What studies say about Andarine
Gao and colleagues reported in Endocrinology (2005) that S-4 restored muscle and bone in castrated rats. Kearbey and colleagues later showed it reduced bone loss in ovariectomized rats.
Andarine is also known for binding to androgen receptors in the eye, which was linked to vision changes in animal studies.
You can find the papers on PubMed. We don’t make claims beyond what that literature reports.
Weighing and handling Andarine powder
Buying Andarine 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 Andarine powder
To make a stock solution, decide on the final volume and concentration first. For 30mL at 10mg/mL you’d weigh 300mg of Andarine, 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.
How we test Andarine
Every batch of Andarine 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.
How to store Andarine
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 Andarine powder
What can I dissolve Andarine 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.
