Enhanced Overall Strength


Enhanced Endurance

The Dark Horse stack increases endurance, letting you train harder for longer. GW-501516 activates the PPAR-delta pathway, improving fatty acid energy use. Stamina, fatigue, and endurance improve.

Accelerated Muscle Growth

By combining GW-501516 and MK-677, Dark Horse promotes accelerated muscle growth. MK-677 stimulates the production of growth hormone, which enhances muscle protein synthesis and supports the development of lean muscle mass. This results in greater muscle fullness, improved muscular definition, and an overall more sculpted physique.

Enhanced Recovery

Dark Horse promotes post-workout recovery by allowing your muscles to repair and rebuild more efficiently. The ability of MK-677 to increase GH levels promotes faster recovery by promoting tissue regeneration and reducing muscle damage. This reduces soreness, promotes faster healing, and allows you to return to training with less downtime.

Improved Fat Loss


With Dark Horse, you can experience improved fat loss and body recomposition. GW-501516’s activation of the PPAR-delta pathway enhances the body’s ability to burn stored fat as fuel, resulting in a more efficient metabolism and increased fat oxidation. This supports a leaner physique and helps shed excess body fat.


Enhanced Overall Strength

Dark Horse has the ability to significantly boost overall strength levels. The endurance-boosting effects of GW-501516, combined with the muscle-building properties of MK-677, contribute to increased strength gains. This translates to better gym performance, allowing you to lift heavier weights, perform more reps, and set new personal records.
