SARM MK2866 (Ostarine)
Description
What is MK2866 10 (Astera Labs)?
Astera Labs ostarine in 10mg tablets, 50 to a sachet. The mildest SARM, best used to hold muscle through a cut.
Also sold as ostarine, MK-2866 or enobosarm.
Ostarine is the mildest and most studied of the SARMs, and the one most people meet first. It binds the androgen receptor selectively in muscle and bone, producing lean tissue and strength without much of the androgenic activity that comes with a steroid. What it is best at is holding muscle when calories are low.

Frequently asked questions
Do SARMs really need PCT?
Yes. This is the single most repeated piece of bad advice about them, and it costs people months of feeling flat while they wait for something to recover on its own.
SARMs are selective, not non-suppressive. They act on the androgen receptor and your body responds by shutting down its own production, exactly as it would with a steroid. A SERM such as tamoxifen or clomiphene is what restarts it.
Are SARMs safer than steroids?
Less androgenic, which is a real difference: less hair loss, less acne, less prostate effect at comparable results.
Not safer across the board though. They suppress testosterone, they push cholesterol the wrong way, and the oral ones raise liver markers. Trading one set of risks for a smaller set is not the same as trading it for none.
How suppressive is ostarine really?
Less than the others here, which is why it is the usual starting point, but real. At 10mg for six weeks many people see modest suppression that recovers quickly; at 25mg for eight it is more substantial.
Dose and duration both drive it. Bloodwork afterwards tells you where you actually are rather than how you feel.
What is it best used for?
Holding muscle through a cut. That is the thing ostarine does better than it does anything else, and it is why it turns up in recomposition phases rather than bulks.
If you want size, it is the wrong compound and something stronger is the honest answer.
How long should a cycle be?
Six to eight weeks at 10 to 25mg a day. Longer runs deepen suppression without adding much.
Allow at least as long off as you were on, with post-cycle therapy through the first part of it.
