MK-2866-25mg research overview
MK-2866, also called ostarine, is a non-steroidal selective androgen receptor modulator supplied as 30 capsules at 25mg each.
SARMs are studied for a specific pharmacological question: whether a ligand can bind the androgen receptor and produce different transcriptional outcomes in different tissues. Steroidal androgens bind the same receptor everywhere, so their effects on muscle, bone, prostate and skin cannot be separated. A non-steroidal ligand adopts a different binding conformation, recruits a different set of coactivators and corepressors, and in preclinical models has been reported to produce tissue-differentiated responses. MK-2866 is among the most extensively characterised compounds in that class and is frequently used as a reference against which newer modulators are compared.
Published research has examined androgen receptor binding affinity, coregulator recruitment, transcriptional profiles across tissue types, and endpoints in muscle and bone preparations. Savage Labs also stocks RAD-140, a structurally distinct SARM with a different binding profile, for comparative work. MK-2866 is a research chemical, not a dietary supplement and not an approved therapeutic; the capsule format describes packaging and does not establish suitability for consumption. Store at room temperature. For laboratory research only. Not for human or veterinary use.

Questions about this listing
- What form does MK-2866-25mg come in?
Oral Capsules The size options listed on this page — 30 capsules — are what is available, and the vial labelling shown in the product images above is the reference for what a vial contains.
- How should MK-2866-25mg be stored?
Room temperature. Storage requirements differ across the catalog — some listings are refrigerated, others held at -20°C, others at room temperature — so read this row rather than assuming from a neighbouring product.
- What does the 99% figure on this listing mean?
It is the purity reported for this material. It is a reported value rather than one Savage Labs has independently verified for the lot you receive, and it does not describe net peptide content. How peptide purity is reported and net peptide content cover what the number does and does not tell you.
- What documentation is available for MK-2866-25mg?
Batch-specific certificates of analysis and test methods on request. Confirm that any report matches the lot you intend to order — reading a peptide certificate of analysis covers which field answers which question. Ask about documentation for this listing, or see the full FAQ for ordering, shipping and returns.
- What else is grouped with MK-2866-25mg?
It is catalogued under SARMs & Capsules, where the category page describes what separates the compounds in the group.
Ordering, payment, shipping and returns are answered on the full FAQ.
