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.

Andarine in published research
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.
Working with Andarine in capsule form
Capsules take the weighing out of the job. Every capsule contains the same amount of Andarine, 25mg, filled and counted before the bottle is sealed.
If you need amounts that don’t match the capsule size, the powder is more flexible, because you can weigh exactly what each sample needs and make up your own solutions or capsules at whatever strength your protocol calls for. Capsules are best for repeat work where the amount doesn’t change. Keep the lid tight, since moisture is the main thing that degrades capsule contents.
Planning a study with Andarine capsules
Work out how many capsules your study needs before you order. Multiply the number of subjects by the number of administrations per subject, then add a few spare for losses. With 60 capsules in a bottle, that tells you straight away how many bottles to buy.
Keep all the capsules for one study from the same batch where you can. It removes batch-to-batch variation from your results.
Andarine quality and testing
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. Keep the desiccant in the bottle and the lid closed tight. Label anything you decant with the compound, amount and date, and keep it out of reach of children and pets.
