    Frequently Asked Questions

    check_box

    What is a Pre Workout?

    A pre-workout supplement is a dietary product designed to be consumed before exercise, aiming to enhance athletic performance.
    While formulations vary, the overall goal is to optimise workout effectiveness by providing a temporary performance edge.

    check_box

    How much Pre Workout should I take?

    The appropriate amount of pre-workout supplement to take varies significantly depending on the specific product, individual tolerance, and personal goals.
    Because pre-workout formulations can be potent, especially regarding stimulants like caffeine, beginning with a half-dose allows you to assess your sensitivity and avoid potential adverse effects like jitters, nausea, or rapid heart rate.
    Gradually increase the dosage only if needed and tolerated, and never exceed the maximum recommended serving.

    check_box

    How long does Pre Workout last?

    The duration of pre-workout effects varies depending on the specific ingredients, individual metabolism, and dosage.
    Typically, the stimulating effects of caffeine, a common pre-workout ingredient, can last for three to six hours.
    Other ingredients, like beta-alanine or creatine, have effects that build up over time with consistent use rather than providing an immediate, short-lived boost.
    Therefore, while you might feel the peak energy and focus within 30-60 minutes of consumption, the overall effects on performance and muscle function can extend beyond that timeframe.

    • Kingslayer Pre Workout

      This is Kingslayer, the pre-workout from Pure Labs. This is a 30 serving product with each serving size at 15 grams. The flavor is Summer Solstice which from my best guess has notes of tropical fruits. A little hard to pin down but still enjoyable. Going over the formula, you get 6 grams of L-Citrulline, 3.2 grams of Beta Alanine, 1 gram of L-Tyrosine, 500mg of Citicoline, 400mg of Caffeine Anhydrous, 350mg of Lion’s Mane Mushroom, 300mg of Eria Jarensis, 200mg of Juglans Regia, 200mg of L-Theanine, 75mg of Pink Himalayan Salt and 5mg of Black Pepper Extract. The dosages of Citrulline and Beta Alanine are standard amounts you’ll commonly find in pre-workouts and these are not the shining stars of the formula. That designation is for the stimulants and energy components. And they certainly play out nicely with this one. You get a very big mood boost that hits shortly after taking a serving. It puts you in a very positive state of mind where you are really happy to train. You feel very alive and awake along with feeling clear headed. It borders on feeling euphoric but I wouldn’t quite go that far. It is just a very smooth energy hit where your mind feels clear and focused. Zero side effects and the energy component wasn’t too much at all. It really plays out so nicely and if you are looking for a type of pre-workout that really promotes a mood boost, this is one worth using. At 30 servings, it’s a great value for money as well. You could add on a pump product to this if you’d like as again, this isn’t the product’s strongest area. But without a doubt, I would recommend this one and give it my seal of approval.

    • Great Product

      I decided to try this pre workout as i have been taking PR3 which is a great product.
      I purchased the Summer Solstice flavour, it is pleasant, but prefer the PR3 Ultimate flavour. If the Frozen Blue Ice flavour is available, next time i order Kingslayer i will try it.
      I take the pre-work before and during a deadlift session, and have hit my goals each time, feeling focused and determined.
      I would definitely recommend this product to anyone considering trying it.
