Product Description



Driven by success, motivated by quality and excited by innovation, Genetix Nutrition alongside their internal research team have designed, developed and launched a high stimulant, nutrient-packed pre-workout that has been made to pack both a punch of energy and a punch of nutrients.

  • Extreme Energy
  • Maximum Strength
  • Ultimate Pump

Designed to take neuro-excitatory function beyond your potential, Genetix Stim Fx is a hard-hitting, nutrient-packed pre-workout that drives cognitive performance to peak levels of performance while synergistically supporting physiological performance enhancement.

Combining key amino acids to support cellular energy restoration, enhance peripheral blood flow and improve lactic acid removal, not only will Stim Fx drive performance up but it will also enhance recovery.

Experience the effects of Stim Fx!

Core Ingredients

Citrulline Malate

Utilising an evidence-based, scientifically efficacious serving size of Citrulline Malate, ensures you will be able to resynthesise ATP at a faster rate while also supporting the biosynthesis of Arginine, which is responsible for promoting vasodilation and an increased level of blood flow to the working limbs.

Beta Alanine

Beta Alanine is a rate-limiting endurance enhancing amino acid, responsible for increasing intramuscular Carnosine levels and the body’s ability to rid itself of lactic acid during high-intensity exercise.


Combining Agmatine with other nitric oxide promoting ingredients enhances their effect as Agmatine may inhibit nitric oxide synthase, which is an enzyme responsible for breaking down nitric oxide and reducing blood flow.

Stimulant Blend (Caffeine, Alpha GPC, Eria Jarensis, Iso P Synephrine)

This 4-way blend works synergistically to stimulate an intense cascade of adrenaline, dopamine and acetylcholine levels in the brain, which works in harmony by increasing mood, stimulating more energy availability, mitigating sedation and enhances complete cognitive performance.

Huperzia Serrata

Found naturally within Toothed Clubmoss, Huperzia is responsible for blocking the reuptake of the stimulatory neurotransmitters released from the stimulant blend, meaning no crash and a longer effect on cognitive performance.

Final Thoughts

As the name suggests, Stim Fx is a hardcore pre-workout stimulant with all the bells and whistles.

Start with ½ a scoop to assess your tolerance and work your way up.



Consume 1 serve (1 scoop) with 300ml of water. For best results consume 15 - 30 minutes prior to exercise. Recommended daily consumption - 1 serving.

Crazy pumps Review by Tinkle
This stuff is great. Partner and I both use it. And the pump is insane! And the burst of energy is great too. Keeps us going for nearly two hours at the gym. Only downfall for me is that I sometimes feel nauseous and I can't handle the taste sometimes. But my partner loves the taste. (Posted on 21/01/2018)
Wow.Review by Brydon
To be completely honest, the first time I ever tried this preworkout, I legitimately thought I was going to pass out. I could quite honestly feel my heart beating out of my chest, and this was before I had even been to the gym! Though my first experience was short of ideal, it was entirely due to the fact that I had taken the pre-workout on an empty stomach, whilst intermittently fasting. Given this, I decided to give the product another shot and took it after a meal like you're advised to do, and my whole perception of the product changed. This is quite honestly the best preworkout I have ever taken for a multitude of reasons. I have taken a significant amount of preworkouts, many of a similar caliber in terms of the ingredient profile, but this product definitely takes the crown. The well-researched implementation at the optimal dosages of the ingredients that increase nitric oxide flow, give energy and provide benefits to performance have well been thought out by Genetix Nutrition, and as such, there is no need to double up on the doses of the preworkout leading to excessive amounts of caffeine and stimulants. There is also no need to supplement with additional ingredients to get anything substantive out of the product. Whilst eating a diet in a deficit of calories with minimal carbs, this product has given me pumps as though I am eating 3800 calories with a ridiculous amount of carbohydrates. In addition to this, after the initial shock of the high level of potent stimulants within the product, the focus was absolutely unreal. Additionally, the Eria Jarensis stimulant within the product is no joke, and will give you an enormous euphoric sensation and will motivate you to achieve higher and lift heavier. Personally, since trying this preworkout I have never experienced any crash, nor has it been too excessive a product that I haven't been able to sleep, albeit I have not experimented with the product at night time. Whilst I definitely DO NOT recommend taking this product fasted with any level of stimulant tolerance, I see no reason to not give this product a try given NW's 5 scoop return policy. If you are starting out training, or are sensitive to stimulants and or caffeine in general, I highly recommend assessing your tolerance with the half scoop stated on the product. Well done Genetix and NW on the astounding product. (Posted on 20/01/2018)
Its bloody stong ehReview by Leaves
I feel this is more potent than Annihilate Black Label. I take 3/4 of a scoop of Annihilate Black Label & I only need 1/2 scoop of Stim FX. (Posted on 18/01/2018)
