Dual Compound Research Stack (RAD-140 + YK-11) — 30 Capsules

Product Format: Dual Capsule Set (2 x 30 Capsule Bottles / 60 Total Capsules)

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

Dosage Spec: RAD-140 (20mg/cap) | YK-11 (10mg/cap)

Primary Focus: Myostatin Inhibition, Extreme Muscle Density, Explosive Strength & Force Production, Dry Anabolic Growth

Product Overview

The Dual Compound Research Stack pairs two of the most potent anabolic research agents in chemical biology: RAD-140 (Testolone) and YK-11 (Myostine) in high-potency, pre-measured 30-capsule bottles.

Designed for advanced laboratory research protocols examining maximal skeletal muscle hypertrophy, this stack combines the high-affinity tissue selectivity and explosive strength output of RAD-140 with the myostatin-inhibiting, follistatin-inducing mechanism of YK-11. Together, they form an aggressive dual-action protocol for investigating tissue density and power output beyond natural genetic ceilings.

What Each Compound Is Used For

1. RAD-140 (Testolone) — 20mg / Capsule

• Dosage per Capsule: 20 mg (30 Capsules per Bottle)

• CAS Number: 1182367-47-0

• Classification: Selective Androgen Receptor Modulator (SARM)

Primary Research Applications & Uses:

• Rapid Lean Muscle Mass: Possesses an exceptionally high anabolic-to-androgenic ratio targeted at driving rapid lean tissue hypertrophy.

• Explosive Power & Strength Output: Significantly boosts force production, heavy lifting performance, and workload threshold in skeletal muscle models.

• Targeted Anabolic Selectivity: Binds strongly to androgen receptors in muscle and bone with low activity in non-target tissues.

• Hard, Dry Muscular Appearance: Promotes a dense, dry, and vascular look without causing subcutaneous fluid retention or estrogenic conversion.

2. YK-11 (Myostine) — 10mg / Capsule

• Dosage per Capsule: 10 mg (30 Capsules per Bottle)

• CAS Number: 1370003-76-1

• Classification: Steroidal SARM / Myostatin Inhibitor

Primary Research Applications & Uses:

• Myostatin Inhibition via Follistatin: Induces Follistatin production in muscle tissue, neutralizing Myostatin (the body's natural muscle-limiting protein).

• Extreme Muscle Hypertrophy: Heavily documented for driving rapid, dense, and hard muscle growth beyond standard genetic limits.

• Significant Load Resistance: Enhances total force production, bone mineral density, and heavy load resistance in muscle tissue trials.

• Non-Aromatizing Finish: Does not convert to estrogen, preserving a tight, dry, and detailed muscular finish.

Why Use RAD-140 & YK-11 Together? (The Dual Compound Stack)

Combining RAD-140 (20mg) and YK-11 (10mg) creates an uncompromised synergistic protocol for extreme muscle density, force production, and growth:

• Myostatin Suppression + High Anabolic Signaling: While YK-11 suppresses myostatin to remove genetic limits on tissue expansion, RAD-140 provides strong androgen receptor activation to maximize muscle protein synthesis.

• Unmatched Force Production & Strength: Unites two top-tier strength-enhancing compounds to evaluate maximum force output and heavy load resistance under intensive exertion protocols.

• Ultra-Dry, High-Density Conditioning: Neither compound aromatizes into estrogen, resulting in a dense, hard, and vascular muscle structure with zero fluid retention.
