Below we have answered some commonly asked questions about this product.
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.
