Below we have answered some commonly asked questions about this product.
Why does the product recommend mixing one serving with 1.1L of water?
Our recommendation to mix our high-stim pre-workout product with 1094mL of water is derived from the guidelines outlined in the Food Standards Code of Australia.
According to the Code, caffeinated beverages should have a caffeine concentration that falls between 145 mg/L and 320 mg/L. Given our product contains 350mg of caffeine per serving, by using 1094mL of water, we ensure the resulting caffeine concentration of the mixed drink remains compliant with the mandated range. This guideline is set to ensure both regulatory adherence and the safety of our consumers, providing an optimal and safe consumption experience.
What does the research show for pre-workout supplementation?
The Amino Z High-Stim Pre-Workout contains scientifically proven ingredients in efficacious dosages. Here are some key pieces of research to support their usage.
1. Citrulline malate improves blood plasma levels and exercise performance [1][2]
2. Beta-alanine improves muscular performance during activity [3]
3. Caffeine consumption enhances performance and reduces exercise-induced fatigue [4]
4. Glycerol Monostearate increases cellular hydration [5]
5. Glycerol monostearate supplements have been shown to enhance exercise performance and prevent fatigue accumulation [6]
6. Pre-workout sodium ingestion increases pre-exercise hyperhydration and improves performance [7]
7. Taurine has been shown to improve muscular endurance while simultaneously causing significant improvements in muscle strength [8]

Why is this product so much cheaper than similar products on the market?
Many other brands incur a high degree of costs associated with producing products. It is not uncommon for a product to be produced by a third-party manufacturer and then shipped (or imported) to a wholesaler. The wholesaler then sells to a retail store, who on-sells to the customer. The end result is that often four separate businesses are taking profits at each stage (the brand itself, the manufacturer, the wholesaler and the retailer).
We take a very different approach which allows us to keep our cost structure down and we pass those savings on to you, without sacrificing product quality.
We have our own purpose-built manufacturing plant located in Sydney Australia and we sell directly to you. This eliminates all additional parties from the process, thereby eliminating a lot of unnecessary costs.
The significant cost savings we incur allow us to invest into high quality ingredients while still offering a significantly cheaper final product.
I haven't tried this product before. What if I don't like it?
Because we manufacture this product ourselves, we believe that the onus is on us to produce a high quality product that you're going to love.
That's why we have our 110% Guarantee. Basically if you try it and you don't love it, just reach out to us. You can receive a 110% store credit, or a full refund.
