This product comes in a standard 1kg size. Other sizes are sent as multiple items. For example, 3kg will be sent as 3x 1kg items.
We do this to reduce manufacturing costs and pass those savings on to you. This also allows you to maintain product freshness in unopened items. Don't forget that you can also choose the Multiple Flavours option (above) in larger pack sizes while getting a much lower per-unit price!
NO NONSENSE. JUST PROVEN INGREDIENTS.

Which allergens are processed in the Amino Z manufacturing facility?
Milk, fish, tree nuts, gluten and peanuts.
Amino Z conducts thorough, regular and systematic cleaning and anti-cross contamination measures to ensure your product is safe to consume
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.
