Product information

YK-11 (Myostine) Advanced Research Capsules — 30 Capsules

Product Format: Standalone Capsule Bottle (30 Capsules Total)

Purity Standard: ≥ 99.0% (HPLC Verified Active Compound)

Dosage Spec: YK-11 (10mg/capsule)

Primary Focus: Myostatin Inhibition, Follistatin Expression, Extreme Muscle Density & Strength Output

Product Overview

YK-11 (Myostine) is widely considered one of the most powerful and advanced research compounds in chemical biology. Possessing a unique steroidal structure with SARM-like tissue selectivity, YK-11 is heavily studied for its dual-action mechanism: acting as a high-affinity androgen receptor agonist while simultaneously inducing Follistatin gene expression to inhibit Myostatin.

Formulated in pre-measured 10mg capsules, this product provides precise milligram accuracy for laboratory protocols investigating extreme muscle cell hypertrophy, strength output, and cellular growth pathways beyond natural genetic limits.

Key Research Applications & Benefits

  • Myostatin Inhibition via Follistatin: Uniquely stimulates muscle cells to produce higher levels of Follistatin, an autocrine glycoprotein that neutralizes Myostatin (the body's natural muscle growth-limiting protein).

  • Extreme Muscle Hypertrophy: Heavily documented in research literature for driving rapid, dense, and hard muscle tissue growth far exceeding standard SARMs.

  • Significant Power & Force Output: Significantly enhances physical strength, force production, and heavy load resistance in muscle tissue models.

  • Dry, Vascular Finish: Does not convert to estrogen, producing a hard, tight, and dry muscular appearance with zero liquid retention or bloating.

Compound Specifications

  • Chemical Name: (17α,20E)-17,20-[(1-methoxyethylidene)bis(oxy)]-3-oxo-19-norpregna-4,20-diene-21-carboxylic acid methyl ester

  • CAS Number: 1370003-76-1

  • Active Dosage: 10 mg per capsule (300 mg total per bottle)

  • Chemical Structure: Steroidal SARM / Myostatin Inhibiting Compound

What’s Included in the Box

  • 1x Bottle YK-11 (Myostine) — 30 Capsules (10mg per capsule) in a pharmaceutical-grade HDPE bottle.

  • Batch-Specific Certificate of Analysis (COA): Access to independent HPLC purity assay documentation confirming 99%+ compound purity.

  • Tamper-Evident Safety Seal & Moisture Control: Industrial heat-sealed neck band with internal silica desiccant packet to maintain chemical stability.

Quality Assurance & Standards

  • Precise Capsule Dosing: Eliminates measurement errors and liquid volumetric handling with uniform 10mg dosing per capsule.

  • Third-Party HPLC Verified: Every batch of raw active powder is independently tested via High-Performance Liquid Chromatography (HPLC) prior to encapsulation.

  • Pharmaceutical Binders: Encapsulated with inert, non-reactive excipients to ensure rapid absorption and long shelf life.
