YK 11 - Dragon Pharma

Buy YK 11 10 mg tablets by Dragon Pharma at XSteroids. YK-11 is the odd one out among the SARMs: it is steroidal, not nonsteroidal, and it behaves as a gene-selective partial agonist rather than a full androgen. Dragon Pharma supplies it as 10 mg tablets, 100 per pack. This guide covers what the research shows, what is missing from it and how yk 11 dosage is handled in practice.

YK-11 has no approved use and no human data, so the information below is educational only.

About YK 11 by Dragon Pharma

YK-11 is a synthetic steroidal selective androgen receptor modulator, also known as myostine. The class label is accurate but the chemistry is unusual: while most SARMs in this catalog are nonsteroidal molecules built to hit the receptor without a steroid skeleton, YK-11 is a steroid. Anyone describing it as "not a steroid" is repeating a marketing line rather than a chemical fact.

Structurally it belongs to the 19-norpregnane family, and the literature frames it as a gene-selective partial agonist of the androgen receptor - a description that matters more than the category name.

How YK-11 Works

Gene-Selective Partial Agonism

YK-11 does not induce the physical interaction between the N-terminal and ligand-binding domains of the androgen receptor - the N/C interaction required for full receptor transactivation. That is what makes it a partial agonist: it activates some androgen-responsive genes while stopping short of the full programme a compound like testosterone triggers.

Anabolic Potency in the Lab

In C2C12 myoblast assays, YK-11 showed anabolic activity and was more potent than dihydrotestosterone in that specific test. It has also been studied for muscle loss in sepsis and appears in the literature as a myostatin inhibitor. Those are laboratory and animal findings; none of it is human data, and none of it establishes a dose.

YK 11 Dosage and Cycle Practice

Dosing

There is no established human dose. Non-medical use generally runs in single-digit to low double-digit milligrams per day, which is why the tablet here is 10 mg, but that number comes from user logs rather than trials. Because the compound is a partial agonist with a steroidal structure, it should not be treated as interchangeable with the milligram dosing of the better studied SARMs.

What to Expect From the Data

Nothing about YK-11 is confirmed in humans: no half-life, no suppression profile, no side effect list. That is why this card lists the half-life as not established rather than copying a figure from a forum. The honest position is that anyone using it is the experiment.

YK-11 Side Effects and What to Watch

Because it is steroidal and acts on the androgen receptor, the reasonable expectation is an androgenic profile plus suppression of natural testosterone - the same class-level concerns that apply to Ostarine and LGD 4033 - but with no trial data to quantify them. Blood work before, during and after is the only source of information about how it affects a given person, and a recovery plan with a SERM such as Nolvadex or Clomid follows the same logic as for any suppressive compound.

How YK-11 Compares to Other Compounds in This Class

Ostarine is the mildest and most studied, LGD 4033 is stronger with trial data, and S 23 is more potent at the receptor while remaining preclinical. YK-11 sits at the research edge of that group - steroidal, gene-selective and almost undocumented. MK 677 is not a SARM at all, and GW 501516 is a metabolic compound rather than an androgen receptor agonist, so neither belongs in a like-for-like comparison.

Storage Instructions

Store the tablets at room temperature in a dry place, away from direct light and moisture. Keep the pack sealed until use and always store it out of the reach of children.
