Nutrithority Gaint's Brew Intense is marketed as a pre-workout supplement designed to enhance your workout performance by providing maximum energy, focus, pump, and hydration.

It contains a combination of ingredients to support these aspects of your training:

Maximum Energy: Giant's Brew contains three different sources of 450mg caffeine, which provides a quick and intense energy boost. These sources include Caffeine Anhydrous, Caffeine Citrate, and Di-Caffeine Malate. The unique blend of caffeine aims to provide energy without the crash that can follow a high caffeine intake. The caffeine works in synergy with other ingredients like Citrus Aurantium and Rauwolscine to amplify your energy levels.

Maximum Focus: To optimize your workout, focus is crucial. Giant's Brew includes Teacrine and Dynamine, which, when combined, aim to enhance focus, elevate energy levels, and help you get into the zone. Other focus-enhancing ingredients such as L-Tyrosine, Choline Bitartrate, and Huperzine A are also included to help you push through your workout with mental clarity.

Maximum Pump & Blood Flow: Achieving a good pump during your workout is essential for muscle growth and performance. Giant's Brew contains ingredients like Citrulline Malate, Betaine Anhydrous, and Nitrosigine, which are known for their ability to boost nitric oxide levels and increase blood flow. This can lead to improved nutrient delivery to your muscles, enhanced blood flow, and a satisfying pump sensation.

Maximum Hydration: Proper hydration is crucial for workout performance. Dehydration can lead to reduced focus, energy, and muscle function. Giant's Brew includes a blend of electrolytes to support hydration. The Mammoth Hydration blend contains Coconut Water Powder, Magnesium Bisglycinate Chelate, Calci-K, and Himalayan Pink Salt, all of which help replenish essential electrolytes lost through sweat and maintain optimal hydration levels during your workout.

Remember that pre-workout supplements like Giant's Brew are designed to provide a temporary energy and focus boost to help you make the most of your workout. It's essential to follow the recommended dosage and use these supplements in conjunction with a balanced diet and a well-structured exercise routine.
