Description
Liquid Ostarine is a 30mL bottle of Ostarine (MK-2866) at 25mg/mL, tested to 98.04% purity. Ostarine is a nonsteroidal selective androgen receptor modulator (SARM). Sports Technology Labs supplies it for in-vitro research only.
Background on Ostarine (MK-2866)
MK-2866 is ostarine, also called enobosarm or GTx-024, 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. It has gone through several human trials but has never been approved as a medicine, and it’s on the WADA prohibited list.
The mechanism behind Ostarine
Ostarine binds the androgen receptor in the cell’s cytoplasm. The receptor then moves into the nucleus and switches on androgen-responsive genes, the same basic route testosterone uses.
The tissue selectivity comes from how the bound receptor recruits helper proteins, which differs between muscle, bone and prostate cells. Unlike testosterone, ostarine isn’t converted to DHT by 5-alpha reductase or to estrogen by aromatase.

What the literature says about Ostarine
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 more lean body mass than placebo.
Later trials looked at it in breast cancer that carries androgen receptors. Earlier rodent work showed high-affinity receptor binding and muscle and bone gains with little effect on prostate weight.

Where Ostarine fits in the range
Ostarine is the most studied SARM, with human trial data on muscle wasting. Here’s how the nearest options in our range differ:
- LGD-4033 binds the androgen receptor very tightly and has a phase 1 study in healthy men
- RAD-140 is a potent nonsteroidal SARM from Radius Health, later tested in breast cancer
- RAD-150 is a benzoate ester of RAD-140 with no published studies of its own
- S4 (andarine) is an early partial-agonist SARM from GTx with rat data on muscle and bone
- S23 is a high-affinity SARM studied as a male contraceptive in rats
All of them bind the androgen receptor, but affinity, selectivity and the amount of published data differ a lot. Compare them in our liquid SARMs.
How Sports Technology Labs tests Liquid Ostarine
Every batch is sent to MZ Biolabs in Tucson, Arizona, before it goes on sale. They run HPLC for purity and mass spectrometry to confirm identity. The latest certificates for this product read 98.04%.
Scroll through the product photos and the certificate is there, with the test date and the chromatogram.
Both numbers matter. Purity by HPLC means little if nobody checked the identity, and that’s the job mass spectrometry does.
If anything arrives wrong, the 60-day money-back guarantee covers it.
Measuring Liquid Ostarine accurately
Each 30mL glass bottle holds 25mg of Ostarine per mL in USP-grade PEG-400, 750mg in total. A graduated 1mL glass pipette comes with every bottle.
At 25mg/mL, 0.2mL contains 5mg. Draw slowly; the PEG-400 base is thicker than water and a rushed draw leaves air in the pipette.
Keeping Liquid Ostarine stable
A cool, dark shelf is ideal. Keep the cap on between uses so the solution doesn’t pick up moisture.
Shake the bottle gently before drawing if it has been sitting for a while.
