GAT Sport Nitraflex Pre-Workout Chews
GAT Sport Nitraflex Pre-Workout Chews put a full pre-workout into a chewable tablet. Four chews deliver 200mg of caffeine, 4g of L-Citrulline and 3.2g of Beta-Alanine, with under 1g of sugar and no shaker required. Throw a tub in the gym bag and your pre-workout is ready wherever you are.
Dose It Your Way
The real advantage here isn't just convenience — it's control. Each chew contains 50mg of caffeine, so you decide the strength of your serve. Take one chew for a light 50mg lift, two for a moderate 100mg, or the full four for a 200mg hit when you're going after a heavy session.
That's something no powder can offer. Scoop-based pre-workouts lock you into a fixed dose or leave you eyeballing half-scoops. Chews let you match the stimulant load to the session in front of you, the time of day and how you're feeling — which makes this genuinely useful for anyone with moderate caffeine tolerance who's been priced out of most pre-workouts by their dosing.

What's In Nitraflex Pre-Workout Chews?
L-Citrulline (4g) supports nitric oxide production, widening blood vessels to improve blood flow and nutrient delivery to working muscle. This is what drives the pump and fullness you feel as the session builds.
Beta-Alanine (3.2g) helps buffer the acid build-up behind that familiar muscular burn during high-rep work, delaying fatigue so you hold performance deeper into each set. It can cause a harmless tingling sensation on the skin, which is completely normal.
Caffeine Anhydrous (200mg) delivers the energy, alertness and drive, split across four chews for precise control.
L-Theanine (100mg) works alongside caffeine to smooth the energy curve, reducing jitters and softening the crash on the other side.
Betaine Anhydrous supports power output, strength and muscular endurance during heavy training.
Huperzine A supports focus and the mind-muscle connection by helping maintain neurotransmitter activity through the session.
Who Are Nitraflex Chews For?
These suit lifters and athletes who want a serious pre-workout without the ritual of powders and shakers — anyone training straight after work, travelling, or squeezing a session in where a shaker isn't practical. The adjustable dosing also makes them a fit for anyone with moderate caffeine tolerance who finds a full scoop of powder too much.
This is a stimulant-heavy formula built for experienced trainers. If you're new to pre-workout or sensitive to caffeine, start with one or two chews and assess your tolerance before going further.
How To Use GAT Sport Nitraflex Pre-Workout Chews
Fully chew one serving (4 chewable tablets) with 240–300ml of water 30 minutes before training. Chew thoroughly before swallowing and stay well hydrated throughout your session. New users and anyone assessing tolerance should begin with one or two chews.
Do not exceed 4 chews in any 24-hour period. After 8 weeks of continuous use, take one week off before resuming.
Servings: 30 (4 chews per serving)
Nitraflex Pre-Workout Chews FAQs
How much caffeine is in Nitraflex Pre-Workout Chews?
One serving of four chews provides 200mg of caffeine anhydrous, which works out to 50mg per individual chew.
Can I take Nitraflex Chews if I'm sensitive to caffeine?
If you're highly sensitive to caffeine or stimulants, these aren't recommended, as a full serving delivers 200mg. If your sensitivity is mild, the chew format lets you control intake precisely — start with one chew at 50mg and build from there.

Yes, they stack well with non-stimulant supplements such as amino acids, creatine, glutamine and protein powder. Don't combine them with other stimulant-containing products.
Are Nitraflex Chews suitable for beginners?
The formula is built for experienced athletes and lifters. First-time users should assess tolerance to stimulants before use and start with a partial serving.
Do Nitraflex Chews contain sugar?
They contain less than 1g of sugar per serving, making them a low-sugar option for anyone who wants performance without the extra calories.
Do I need to cycle Nitraflex Chews?
Yes. After 8 weeks of continuous use, take one week off before resuming.
How do chews compare to a powdered pre-workout?
