Product Descriptions


Take Nitraflex before workouts and Supertein throughout the day for a complete muscle-building supp regimen.

by Adam Gonzalez

No single product can satisfy all your supplement needs for muscle building. That’s where stacking comes in. At some times of day you need specific supplements that you may not need or want at other times of day. Caffeine is a classic example—great for boosting energy during workouts, but when taken too late, can disrupt sleep, and in turn, recovery. Nitraflex was designed as a pre-workout supplement, and Supertein is its protein complement, providing the raw materials needed for growth and recovery.

This pre-workout was designed to induce reactive hyperemia—the increase in blood in muscle tissue that occurs during training—and to boost T levels. nitraflex contains a high ratio of citrulline to arginine, aminos that spur vasodilation.

Supertein contains a blend of whey, milk, and casein proteins, making it a perfect choice both during the post-workout window and at other times of day. Research has shown that this blend is more effective than taking any single source alone.

Take Nitraflex 30 minutes before training. Start with a half scoop to assess tolerance, mixing with 6–8 ounces of water. take Supertein immediately after workouts (one scoop with 6–8 ounces of water), and up to three doses daily.
