Anabolic Mass Research Stack (MK-677 + LGD-4033) — 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: LGD-4033 (10mg/cap) | MK-677 (25mg/cap)

Primary Focus: Explosive Mass Bulk, Heavy Strength Output, Elevated Growth Hormone (IGF-1), Rapid Recovery & Muscle Fullness

Product Overview

The Anabolic Mass Research Stack pairs two of the most effective non-steroidal mass-building compounds in research chemistry: LGD-4033 (Ligandrol) and MK-677 (Ibutamoren) in high-potency, pre-measured 30-capsule bottles.

Engineered specifically for laboratory research evaluating maximum muscle hypertrophy, this dual stack combines the potent tissue-selective anabolic action of LGD-4033 with the growth hormone (GH/IGF-1) secretagogue activity of MK-677. Together, they create an optimal multi-pathway environment for driving rapid lean tissue accumulation, heavy strength gains, and continuous cellular recovery.

What Each Compound Is Used For

1. LGD-4033 (Ligandrol) — 10mg / Capsule

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

• CAS Number: 1165910-22-4

• Classification: Selective Androgen Receptor Modulator (SARM)

Primary Research Applications & Uses:

• Rapid Lean Muscle Bulk: Widely documented as one of the most effective non-steroidal compounds for accelerating overall muscle size and mass density.

• Exceptional Strength Increases: Heavily researched for increasing total force production and lifting capacity in skeletal muscle models.

• Enhanced Glycogen Retention: Promotes intracellular glycogen storage within muscle tissue, resulting in fuller and more voluminous muscle bellies.

• Targeted Anabolic Efficiency: Binds selectively to androgen receptors in muscle and bone with high affinity, minimizing off-target activity.

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, long-lasting Growth Hormone and IGF-1 secretion without spiking stress hormones.

• Intracellular Fullness & Hydration: Increases intracellular water retention and nitrogen balance, keeping muscle tissue fully hydrated and pumped.

• Accelerated Recovery & Joint Protection: Speeds up cellular repair across muscle, tendon, and ligament tissue following heavy exertion.

• Deep Sleep Quality & Appetite: Optimizes deep REM sleep cycles to enhance natural systemic recovery and nutrient partitioning.

Why Use LGD-4033 & MK-677 Together? (The Anabolic Mass Stack)

Combining LGD-4033 (10mg) and MK-677 (25mg) creates a complementary dual-action protocol for uncompromised size, mass, and repair:

• Tissue Anabolism + Growth Hormone Signaling: While LGD-4033 stimulates androgen receptors to drive raw skeletal muscle growth, MK-677 elevates circulating IGF-1 levels to accelerate cellular repair and muscle protein synthesis.

• Maximal Muscle Volume & Hydration: LGD-4033 increases glycogen retention while MK-677 promotes intracellular hydration, resulting in dramatic muscle fullness and roundness.

• Heavy Strength Gains + Joint Lubrication: LGD-4033 enables heavy force production during exertion trials, while MK-677 provides connective tissue support and joint lubrication to protect under heavy loads.
