YK11: The Myostatin Inhibitor (SARM/Steroid Hybrid)

Active Component: YK11

Brand: YK11 (Deus Medical)

Pack: Oral Tablets (5 mg/tab)

Form: Oral

Product Overview: What Is YK11?

YK11 is a powerful component that is often classified as a SARM (Selective Androgen Receptor Modulator), but its mechanism is structurally and functionally unique.¹ It acts as a gene-specific partial activator of Androgen Receptors (AR).

However, its most notable function is its role as a Myostatin Inhibitor. By stimulating the body to produce Follistatin—a protein that actively blocks Myostatin (a protein that naturally limits muscle growth)—YK11 is designed to promote muscle growth far beyond a user's genetic limitations.²

How YK11 Works (Unique Mechanism)

YK11's action is twofold:

1. Androgen Receptor (AR) Activation: It partially stimulates ARs to promote anabolic effects (muscle and bone growth).³

2. Myostatin Inhibition: Its key mechanism is promoting the synthesis of Follistatin.⁴ By inhibiting the growth-limiting protein Myostatin, YK11 effectively lifts the "genetic brake" on muscle development, leading to potential enhanced muscle growth and strength gains beyond what is typically possible with traditional anabolics alone.⁵

 Recommended Dosage

YK11 is a potent research compound, and only low dosages are suggested.

• Suggested Dosage: 5 mg daily, taken orally.

• Administration: Typically taken once per day.

 Potential Side Effects and Safety Warning

Due to its potent nature and complex mechanism, YK11 carries significant potential side effects. Its status as a research chemical means long-term human safety data is scarce.⁶

Crucial Warning: YK11 is a research compound and is not approved for human consumption. Due to potential risks, including severe liver damage and cancer risk with overuse, extreme caution and medical guidance are paramount before considering its use.

Frequently Asked Questions (FAQs) about YK11

1. What makes YK11 different from traditional SARMs (Selective Androgen Receptor Modulators)?

YK11 is unique because it acts not only as a partial androgen receptor activator but primarily as a Myostatin Inhibitor. Myostatin is a protein that naturally limits muscle growth. By stimulating the production of Follistatin, YK11 blocks Myostatin, potentially allowing muscle growth to exceed natural genetic limits, a mechanism not seen in traditional SARMs like Ostarine or LGD-4033.

2. If YK11 is a SARM, why is liver damage a potential side effect?

Like many oral compounds, YK11 may place stress on the liver. Although SARMs are designed to be more selective than traditional oral steroids, the product information specifically cautions about the potential for liver damage and the risk of cancer with overuse. This highlights the fact that YK11 is a powerful research chemical and is not without significant systemic risk.

3. Why is the risk of "Testosterone Suppression" mentioned if YK11 is a partial activator?

While YK11 partially activates androgen receptors, the body recognizes its presence as an exogenous (external) hormone, signaling the HPTA (Hypothalamic-Pituitary-Testicular Axis) to reduce or stop its own natural testosterone production. Therefore, just like with full steroids, users should anticipate and plan for testosterone suppression and require a proper Post Cycle Therapy (PCT) protocol.

4. Given its potent mechanism, why is the suggested dosage only 5 mg daily?

The low suggested dosage of 5 mg is indicative of YK11's extreme potency and its direct action on gene expression and protein synthesis (Myostatin inhibition). At higher doses, the risk of severe side effects—including liver damage, anxiety, and potential cardiac issues—increases dramatically, making a low, tightly controlled dosage the only viable research path.
