Mass & Growth Research Stack (MK-677 + RAD-140) — 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) | MK-677 (25mg/cap)

Primary Focus: Explosive Mass & Strength, Elevated Growth Hormone (IGF-1), Intracellular Hydration & Accelerated Recovery

Product Overview

The Mass & Growth Research Stack pairs two of the most heavily demanded research compounds on the market: RAD-140 (Testolone) and MK-677 (Ibutamoren) in high-potency, pre-measured 30-capsule bottles.

Designed specifically for research protocols focused on maximal muscle tissue hypertrophy, this stack combines the high-affinity androgenic signaling of RAD-140 with the growth hormone (GH/IGF-1) secretagogue action of MK-677. Together, they create a powerful multi-pathway anabolic environment for rapid mass building, dramatic strength output, and accelerated cellular repair.

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 Muscle Mass & Density: One of the most potent SARMs available, targeted specifically for maximizing rapid lean muscle hypertrophy.

• Significant Power & Strength Output: Significantly boosts force production, overall strength, and training capacity in muscle tissue models.

• High Anabolic Selectivity: Binds strongly to androgen receptors in skeletal muscle with minimal androgenic activity in non-target tissues.

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

2. MK-677 (Ibutamoren) — 25mg / Capsule

• Dosage per Capsule: 25 mg (30 Capsules per Bottle)

• CAS Number: 159752-10-3

• Classification: Growth Hormone Secretagogue (GHS) / Ghrelin Receptor Agonist

Primary Research Applications & Uses:

• Elevated GH & IGF-1 Axis: Mimics ghrelin to stimulate sustained Growth Hormone and IGF-1 secretion without spiking stress hormones like cortisol.

• Enhanced Muscle Fullness & Nitrogen Retention: Increases intracellular hydration and nitrogen retention, ensuring muscle bellies stay full and pumped.

• Accelerated Recovery & Joint Support: Speeds up recovery in muscle, tendon, and ligament tissue following intense physical exertion.

• Optimized Sleep & Appetite: Enhances deep REM sleep architecture, aiding in overall biological recovery and nutrient partitioning.

Why Use RAD-140 & MK-677 Together? (The Mass & Growth Stack)

Combining RAD-140 (20mg) and MK-677 (25mg) creates a synergistic dual-action protocol for maximum size, strength, and recovery:

• Androgenic Mass + Growth Hormone Signaling: While RAD-140 triggers selective androgen receptors in skeletal muscle to build raw mass, MK-677 floods muscle tissue with elevated IGF-1 to accelerate cellular multiplication and recovery.

• Dense Hardness + Intracellular Fullness: RAD-140 delivers a dry, vascular muscle structure, while MK-677 draws hydration inside muscle cells for maximum volume without subcutaneous water retention.

• Extreme Strength + Accelerated Repair: RAD-140 drives heavy strength gains during exertion trials, while MK-677 supports connective tissue, joint lubrication, and muscle repair post-trial.
