Description
With this OTR-AC liquid you get OTR-AC as a measured liquid solution. It comes in PEG (original) or Poly-Cell™ carrier, 30mL or 60mL. Each batch is tested by LC-MS to 99% purity or higher. Prices start at $80.99. It’s sold for laboratory research only.
The same compound comes in other formats too: OTR-AC powder, OTR-AC gel packs and OTR-AC capsules. See all SARM liquids for more options in this format.
What is OTR-AC?
OTR-AC is the acetate ester of ostarine, sometimes listed as ostarine-O-acetate. The acetate group is added to the hydroxyl on the ostarine backbone, which changes how the molecule is handled in metabolism while the core androgen receptor binding structure stays the same.
It’s a newer research compound than ostarine and has far less published data, so most interest comes from comparing it directly with the parent SARM.

What studies say about OTR-AC
There are no published clinical trials of OTR-AC itself. Researchers who work with it usually lean on the ostarine literature, including the 2013 enobosarm phase 2 trial in The Lancet Oncology, and treat OTR-AC as a modified form to compare against.
That makes it a good fit for side-by-side work: same receptor target, slightly different chemistry.

Choosing a size and carrier for OTR-AC liquid
Both bottle sizes hold the same 20mg/mL solution, so the only difference is how much you get. With the PEG (original) carrier, 30mL costs $80.99 and 60mL costs $160.98. The 30mL bottle is the cheaper way to try the format before you commit to a larger one.
You can choose between PEG (original) and Poly-Cell™. Pick one carrier and stay with it for a whole study, because switching halfway through adds a variable you’d have to account for.
Shake the bottle gently before each draw and use a clean pipette every time. Our transfer pipettes and dropper bottles are sold separately.
Making working dilutions of OTR-AC
If your protocol calls for a lower concentration, dilute a measured volume into a clean glass bottle. For example, 1mL of the 20mg/mL solution plus 1mL of carrier gives 2mL at 10mg/mL. Use the same carrier where possible, or a solvent your protocol allows, and mix gently.
Make up only what you’ll use in the short term, and label the new bottle with the concentration and date.
OTR-AC quality and testing
Every batch of OTR-AC 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 OTR-AC
Keep it refrigerated. Keep the cap tight, and don’t leave the bottle in a hot car or on a sunny windowsill. Label anything you decant with the compound, amount and date, and keep it out of reach of children and pets.
