Product Details

The Phase 1 Core Essentials Stack was designed to give you all the products to cover your bases for a great workout and recovery.

WHAT'S INCLUDED:

STIMMED UP® is by far the industry's strongest compliant stimulant heavy preworkout. Our unique and proprietary formulation has been in the works for over 7 months, tested and proven to keep you energized and pumped up for the entire day. Available in two delicious flavors: Candy Apple and Sweet Peach Rings.

PUMP PHASE® provides MONSTER PUMPS and MASSIVE BLOOD FLOW. Combining all of your favorite pump ingredients into one scoop, YOU CAN’T GO WRONG. Available in Lemonade Pump and Fruit Pump.

REDS & GREENS is an essential daily use product that everyone should be taking. From bodybuilders to the average person, this product provides nutrients to promote a healthy life. It contains phyto servings which contain 3 daily servings of fruits and 3 daily servings of greens per scoop. The Strawberry Açaí flavor tastes extremely good and mixes very well.

ISO Clear Whey Isolate Protein is a clean post-workout isolate that is available outside the standard flavors. It offers protein through a light and refreshing drink rather than a heavy filling shake. The mixability and flavors in this product are unparalleled.

Clear Whey Isolate is not common in the industry but the few alternatives out there provide 15-20 servings in their product. Phase 1 ISO is packed with 25 servings of our delicious regeneration formula available in Gym-n-Lime (tastes like your favorite Lemon Lime sports drink) and Paradise Passion (a splash of fruit punch).

Phase 1 Nutrition® Shaker uses patented ProBlend Technology harnessing the power of kinetic energy. Studies show that kinetic based mixing elements that blend against the flow of material provide a more effective and smoother blend than shakers with free moving mixing elements that only flow with the material. It is 100% proudly made in the USA! We only use the absolute best USA grade materials which are FDA Approved to ensure you have a safe and consistent product.
