Description
This is ostarine powder in its raw form: 2,000 mg of MK-2866 sealed in a UV-resistant foil pouch. It suits labs that weigh their own material or make solutions at a concentration we don’t sell.

Ostarine powder is part of our SARMs powder range. If you’d rather skip the weighing, liquid ostarine at 25 mg/mL is ready to measure. For combined studies, the ostarine and cardarine stack is one of our best sellers.
What is ostarine powder?
Ostarine (MK-2866, also sold as enobosarm) is a non-steroidal SARM that GTx Inc. took through several clinical trials. It binds androgen receptors in muscle and bone and has much less effect on the prostate and skin than testosterone does.
As a dry powder it’s a white to off-white solid. It dissolves well in PEG-400 and in common lab solvents like DMSO and ethanol.
What the ostarine powder research says
Enobosarm is the most studied SARM in people. GTx ran trials in older adults, in cancer patients with muscle loss and in women with stress urinary incontinence. The 2011 phase II study in 120 older men and women found a rise in lean body mass and better stair-climb power at 3 mg a day.
Those trials also reported lower HDL cholesterol and some drop in testosterone and SHBG. Enobosarm isn’t FDA approved. You can search the trial papers on PubMed.

Measuring and storage
The pouch holds 2,000 mg of dry powder. Measuring tools aren’t included, so you’ll need an analytical balance that reads to at least 1 mg for accurate work. Weigh in a draft-free spot and reseal the pouch straight away.
Most labs dissolve SARM powders in PEG-400. Bringing the full 2,000 mg up to 80 mL with our PEG-400 gives 25 mg/mL, the same strength as our liquid version. Gentle warming and stirring help it dissolve. Store the sealed pouch in a cool, dry place away from light.
Lab testing and certificate of analysis
Our ostarine powder is tested by MZ Biolabs, an independent lab in Arizona, and packed in the USA. The current certificate of analysis is dated 07/08/25 and reports 98.04% purity. If you need the full COA for your lab records, email us and we’ll send it before you order.
Ostarine powder FAQ
How do I dissolve ostarine powder?
Most labs use PEG-400. Our PEG-400 solvent is the same carrier we use for our liquids.
Is ostarine powder the same as liquid ostarine?
It’s the same compound. The powder is undiluted, so you control the final concentration.
Are measuring tools included?
No. You’ll need your own analytical balance.
Why researchers buy from Sports Technology Labs
A 2017 JAMA study bought 44 products sold online as SARMs and tested them. Only 52% contained a SARM at all, and 39% contained other unapproved drugs. That’s the problem we set out to fix. We start with raw material that’s at least 98% pure, bottle everything in the USA and send every batch to MZ Biolabs before it goes on sale. Liquids go into glass bottles with glass droppers, so there’s no plastic in contact with the solution.
