PROTEIN WORTH GETTING EXCITED ABOUT
We’ve reimagined whey protein isolate so it tastes and performs like something you’ll actually look forward to.
It’s developed in-house by a team that cares just as much about flavour as performance, because there’s no reason you should have to sacrifice great taste for solid nutrition.
WHY AMINO Z WPI?
• 26g+ protein per serve.
• Naturally sweetened with thaumatin. A naturally derived sweetener with no weird aftertaste.
• 25+ flavours with new drops released regularly.
FLAVOURS
Aussie Choc Malt: We threw it right back to childhood with this one. Think back to that choc malt drink you had after school. Classic. Lightly sweet and malty, with soft milk chocolate notes to balance it out. Sweetness Scale: 3/5 Medium.
Brazilian Chocolate (Brigadeiro): Inspired by the classic Brazilian dessert found at parties and celebrations. Velvety chocolate layered with caramelised condensed milk notes. Rich, smooth, and dangerously easy to drink. Sweetness Scale: 4/5 Medium–high.
Brown Sugar Milk Tea: Deep caramelised sweetness with Assam tea notes. Rich, aromatic, and perfectly balanced with molasses warmth. Sweetness Scale: 4/5 Medium–high.
Caramelised Dutch Cookie: Warm caramelised cookie flavour with soft cinnamon spice through the finish. Think speculaas, but smoother and less intense on the gingerbread flavour. Sweetness Scale: 3/5 Medium.
Choc Cherry Delight: Rich dark chocolate with sweet cherry and a very subtle coconut finish. Nostalgic, indulgent, and effortlessly moreish. Sweetness Scale: 4/5 Medium–high.
Chocolate Honeycomb: Milk chocolate paired with sweet honeycomb notes and a velvety texture. Rich, playful, and dessert-leaning without going overboard. Sweetness Scale: 4/5 Medium–high.
Chocolate: Smooth, velvety chocolate with clear cocoa depth. Balanced sweetness without being over the top. Sweetness Scale: 4/5 Medium–high.
Coconut (Buko) Shake: Lightly sweet coconut milk inspired by classic street-market coconut shakes in Manila. Creamy, nutty, and refreshing. Sweetness Scale: 3/5 Medium.
Cookies & Cream Ice Cream: Creamy vanilla loaded with Australian-made chocolate cookie pieces and dark cocoa notes. Thicker, richer, and properly indulgent. Sweetness Scale: 3/5 Medium.
Crème Caramel: Layered toffee and butterscotch flavours with a creamy base and a subtle touch of salt. Rich, balanced, and quietly indulgent. Sweetness Scale: 4/5 Medium–high.
Dark Chocolate: Rich cocoa flavour with lower sweetness and a smooth, bittersweet finish. Bold, refined, and undeniably dark chocolate. Sweetness Scale: 3/5 Medium.
Durian King: Custardy and creamy with a light durian presence. Update (19/01/26): We’re continuing R&D to dial up the signature sulphur notes based on customer feedback. Sweetness Scale: 4/5 Medium–high.
Earl Grey Milk Tea: A bergamot-forward black tea with a smooth, milky base. Elegant, balanced, and a genuine standout. Sweetness Scale: 4/5 Medium–high.
Hojicha Latte: Authentic roasted hojicha from Kyoto with mellow, umami depth. Creamy, lightly sweet, and beautifully smooth. Sweetness Scale: 3/5 Medium.
Iced Coffee: Robust coffee notes rounded out with milk and a hint of vanilla. Smooth, balanced, and café worthy. Sweetness Scale: 3/5 Medium.
Indulgent White Chocolate: Buttery white chocolate with hints of caramel and vanilla. Smooth, lightly sweet, and well balanced. Sweetness Scale: 4/5 Medium–high.
Korean Melon Popsicle: Inspired by one of Korea’s most iconic ice cream flavours, this one stays true to what made it famous. Refreshing on the first sip, then it settles into a smooth, creamy finish that’s just a little more indulgent than you’d expect. Sweetness Scale: 4/5 Medium–High.
Korean Style Banana Milk: Sweet, creamy milk layered with nostalgic banana candy notes and a hint of vanilla custard. A smooth, comforting flavour that tastes like a Korean convenience store classic. Sweetness Scale: 4/5 Medium–high.
Mango Milk: Sweet, sun-ripened mango flavours layered into a smooth, milky base. The Carabao mango finish is juicy and sweet, just like biting into a perfectly ripe mango. Sweetness Scale: 4/5 Medium–high.
Matcha Latte: Earthy matcha balanced with a smooth, milky base. Clean, comforting, and properly matcha-forward. Sweetness Scale: 3/5 Medium.
Mint Choc Chip: Cool peppermint meets creamy milk chocolate. Fresh, smooth, and exactly how the classic combo should taste. Sweetness Scale: 4/5 Medium–high.
Pandan & Coconut: Sweet, lightly grassy pandan blended with gentle coconut creaminess. Smooth, tropical, and quietly addictive. Sweetness Scale: 3/5 Medium.
Signature Milk Tea: Creamy milk tea with soft, aromatic black tea through the finish. Familiar, refined, and quietly addictive. Sweetness Scale: 3/5 Medium.
Taro Milk: A smooth vanilla-milk base balanced with subtle nutty notes and the signature mellow starchiness of taro. Inspired by the creamy taro drinks and desserts we fell in love with. Sweetness Scale: 3/5 Medium.
Unflavoured: Clean, neutral and versatile. Perfect for smoothies, cooking, or anywhere you want protein without flavour interference. Sweetness Scale: 1/5 Very low.
Vanilla Creamy: Classic vanilla ice-cream vibes with a smooth, rounded finish. Softly sweet and effortlessly easy to drink. Sweetness Scale: 3/5 Medium.
Vanilla Custard: A creamy, softly sweet, rounded flavour with warm vanilla notes and gentle dairy richness. Sweetness Scale: 3/5 Medium.
Vanilla Malt Milk: Light vanilla and milk flavours paired with rich, sweet malty notes, a true nod to the classic old-school milkshake. Sweetness Scale: 4/5 Medium–high.
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.
