i-SURGE Intra Workout Formula

TPW™ i-Surge is a non-stim based intra workout formula designed to be taken during your workout to help increase strength, speed, power and endurance, as well as combat fatigue. It comes in a range of all natural flavours for the ultimate supplement to take during your workout.

The unique formulation of i-Surge means it is a high performance supplement for anyone looking to smash training plateaus. It includes a wide variety of cutting-edge natural ingredients that synergistically work together to raise your maximum output and intensity during training or competition.

i-Surge Intra Workout from The Protein Works™ is an advanced intra workout formula that’s been scientifically formulated with the purest forms of performance enhancing amino acids and extracts. Each of the ingredients in i-Surge have been shown to individually help improve performance. Combined together in the amounts and ratios found within the i-Surge formula, they work synergistically when taken during your workout phase to help increase strength, speed, power and endurance, as well as contribute to combating fatigue.

Importantly, i-Surge has been purposely made with a wide variety of non-stim based ingredients. This means it works very well with our potent pre-workout RAZE™ to ensure both your pre-workout and intra-workout supplementation is taken care of effectively. i-Surge is also the ideal supplement to take before your workout as a pre-workout, if you are sensitive to caffeine or just want a non-stimulant based, performance enhancing formula.


i-Surge Formula Insight

To help you better understand the theory and science behind our unique i-Surge formula, below we’ve listed each of the active ingredients and given some key insights into how they will help improve both the intensity and duration of your workout:

  • iBCAA - Shown to promote recovery & lean muscle mass. We use premium grade instantised material for easy mixing.
  • Beta Alanine - Helps delay onset of muscular fatigue, and improve exercise performance and power output.
  • L- Citruline - Helps improve overall improvement in aerobic performance and a reduction in fatigue during intense training.
  • Taurine - Plays an important role in protein synthesis, cell hydration and cardiac function.
  • N-Acetyl L-Carnitine - Shown to improve the efficiency of the body to burn use fat as a source of fuel and improve muscular endurance.
  • Electrolyte Blend - Comprising sodium, potassium, calcium and magnesium, this is essential for maintaining correct hydration levels, avoiding cramps and ensuring the muscles contract and work at their optimal level.
  • B Vitamins- Essential for turning carbohydrates, protein and fat into energy, and for the proper functioning of the nervous and immune system.

It's a good product, I just have one major issue. As I'm dieting and strictly controlling my macros I can't use it because you don't declare the macros and calories contained in the product.

What are the macors and calories??

If you declare the contents I would have rated at 5star but can't as I don't know how it impacts my macros.
