Description
MK-2866 Ostarine liquid from Blue Sky Peptide is a 30mL glass dropper bottle of MK-2866 (ostarine) at 35mg/mL, 1,050mg in total. MK-2866 is a nonsteroidal selective androgen receptor modulator (SARM). This batch tested at 99.8% purity. It’s sold for laboratory research only.
About MK-2866 (ostarine)
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.
How MK-2866 acts in the lab
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.

Published MK-2866 studies
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.

MK-2866 compared with similar compounds
MK-2866 Ostarine liquid is easier to place once you see it next to the compounds it’s usually compared with. MK-2866 is the most studied SARM, with a phase 2 trial in cancer-related muscle loss. The others:
- LGD-4033 binds the androgen receptor very tightly and has a published phase 1 study
- RAD-140 showed strong muscle selectivity in monkeys and was trialed in breast cancer
- S4 Andarine is a partial androgen receptor agonist, one of the first SARMs from GTx
- YK-11 is a steroidal partial agonist that raises follistatin in muscle cells
- MK-677 is an oral ghrelin mimic that raises GH and IGF-1, not a SARM
- GW501516 is a PPAR-delta agonist that shifts muscle toward burning fat, not a SARM
Only the first five act on the androgen receptor. MK-677 and GW501516 are sold alongside SARMs because they’re studied for body composition too, but they work through different receptors. See them all on our SARMs page.
Working with MK-2866 Ostarine liquid
The concentration is 35mg/mL, so the math is simple: every 1mL holds 35mg, and every 0.1mL holds 3.5mg. The whole 30mL bottle holds 1,050mg.
The dropper in the cap is fine for transferring liquid, but it isn’t marked finely enough for accurate measuring. For that, use a graduated 1mL measuring dropper, which reads in 0.1mL steps and costs $1.99.
Storing MK-2866 Ostarine liquid
Store the bottle at room temperature, away from heat and light, with the cap screwed on firmly. There’s no need to refrigerate it.
Lab-tested MK-2866 Ostarine liquid
Purity for this batch of MK-2866 Ostarine liquid came back at 99.8% by HPLC and mass spectrometry. That’s the figure for the batch currently in stock.
The label on each bottle shows the compound, the strength and the batch. Ask us for the certificate of analysis for your batch and we’ll email it over.
Keep the batch number with your records. It’s the quickest way to match a bottle to its paperwork later.
