Dual Compound Research Stack (MK-677 + GW-501516) — 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: GW-501516 (25mg/cap) | MK-677 (25mg/cap)

Primary Focus: Extreme Cardiovascular Endurance, Rapid Fat Oxidation, Elevated Growth Hormone (IGF-1), Muscle Fullness & Recovery

Product Overview

The Dual Compound Research Stack pairs two highly complementary non-androgenic research compounds: GW-501516 (Cardarine) and MK-677 (Ibutamoren) in high-potency, pre-measured 30-capsule bottles.

Formulated for advanced research protocols targeting body composition and performance, this stack operates entirely outside androgen receptor pathways. It allows researchers to investigate the dual benefits of PPARδ-mediated metabolic fat oxidation and cardiovascular stamina alongside Growth Hormone (GH/IGF-1) secretagogue action for accelerated cellular recovery and lean mass preservation.

What Each Compound Is Used For

1. GW-501516 (Cardarine) — 25mg / Capsule

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

• CAS Number: 317318-70-0

• Classification: PPARδ (Peroxisome Proliferator-Activated Receptor Delta) Agonist

Primary Research Applications & Uses:

• Extreme Endurance & Stamina: Heavily researched for increasing VO2 max, aerobic capacity, and cardiovascular stamina in muscle tissue models.

• Rapid Fat Oxidation: Switches the body's energy preference from glucose to free fatty acids, accelerating metabolic fat burning.

• Enhanced Lipid Profile & Metabolic Efficiency: Documented for supporting healthy lipid metabolism and increasing glucose uptake in skeletal muscle.

• Non-Stimulant Performance: Boosts training volume and endurance capacity without stimulating the central nervous system or elevating heart rate.

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 cortisol levels.

• Lean Muscle Preservation & Fullness: Promotes intracellular hydration and nitrogen retention, ensuring muscle bellies stay full during fat-loss protocols.

• 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 biological recovery and nutrient utilization.

Why Use GW-501516 & MK-677 Together? (The Endurance & Recomp Stack)

Combining GW-501516 (25mg) and MK-677 (25mg) creates an optimal non-hormonal protocol for fat loss, cardiovascular output, and recovery:

• Peak Fat Burning + Muscle Protection: While GW-501516 accelerates fat oxidation and lipid utilization, MK-2866/MK-677 elevates IGF-1 to prevent lean tissue breakdown during caloric deficits.

• Maximum Stamina + Rapid Recovery: GW-501516 allows for higher exertion volume during research trials, while MK-677 ensures rapid cellular repair and joint protection post-exertion.

• 100% Non-Hormonal & Non-Suppressive: Neither compound binds to androgen receptors, meaning this stack does not suppress natural testosterone production or require post-cycle protocol management.
