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.

Questions & Answers

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

How is this whey protein isolate protein different to other whey proteins?

Whey protein can come in various forms, most commonly whey protein isolate (WPI) and whey protein concentrate (WPC). Whey protein isolate is a very high quality form of whey protein which undergoes additional processing relative to whey protein concentrate. This results in a higher protein percentage and a lower fat and carbohydrate percentage. WPI is a superior protein to be consuming post-workout to help facilitate recovery and muscle growth for this reason. It is also more expensive than its WPC counterpart.

Many whey proteins contain either WPC, or a blend between WPI and WPC. These other whey proteins are not of an equivalent quality. Simply look at the nutritional panel to see what type of whey protein(s) are used in the product.

What does the research show for whey protein supplementation?

1. A 2017 double-blind crossover study found that "whey protein supplementation enhances whole-body anabolism, and may improve acute recovery of exercise performance after a strenuous bout of resistance exercise." [1]

2. Whey protein has been found to assist in muscular recovery and performance improvements in resistance training individuals. [2]

[1] West DWD, Abou Sawan S, Mazzulla M, Williamson E, Moore DR. Whey Protein Supplementation Enhances Whole Body Protein Metabolism and Performance Recovery after Resistance Exercise: A Double-Blind Crossover Study. Nutrients. 2017 Jul 11;9(7):735. DOI: 10.3390/nu9070735. PMID: 28696380; PMCID: PMC5537849.

[2] Cintineo HP, Arent MA, Antonio J, Arent SM. Effects of Protein Supplementation on Performance and Recovery in Resistance and Endurance Training. Front Nutr. 2018 Sep 11;5:83. DOI: 10.3389/fnut.2018.00083. PMID: 30255023; PMCID: PMC6142015.

Do I need to use exactly 250mL of water (or other liquid) with one serving size?

Although this is our recommended serving suggestion for optimal flavour and texture, this is certainly not necessary. If you prefer a thicker consistency and stronger flavour, you can reduce the liquid component. Alternatively if you prefer a weaker taste, you can increase the total amount of liquid. The 250mL of liquid is to be used as a guide.

What is the amino acid profile or content of WPI?

Below is the amino acid profile per 100g of protein (unflavored):

Alanine: 5500mg

Arginine: 2200mg

Aspartic Acid: 12100mg

Cysteine: 2400mg

Glutamic Acid: 19200mg

Glycine: 1700mg

Histidine: 1800mg

Isoleucine: 7300mg

Leucine: 11400mg

Lysine: 10800mg

Methionine: 2400mg

Phenylalanine: 3200mg

Proline: 6500mg

Serine: 5000mg

Threonine: 7700mg

Tryptophan: 2100mg

Tyrosine: 3000mg

Valine: 6400mg

Is Amino Z Whey Protein Isolate halal certified?

The primary raw material, whey protein isolate, has been halal-certified. However, the final product has not been halal-certified by a third party.

What type of rennet is used in the WPI?

The rennet used in the whey protein isolate is microbial. No animal rennet is used.

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.

Such a great texture, easy to mix, no lumps, and so delicious! I will get this one again! I've tried it in water as a shake and in yogurt, both times super tasty and easy to mix.

Making protein great again!
By Oneil reviewed on 11/06/2026

Verified buyerA verified buyer is someone who has purchased this product from Amino Z

I've tried many protein powders over the years, and when I first came across Amino Z, I was a little apprehensive. Many larger brands invest heavily in marketing, which can create the perception that they're automatically superior products.

After giving Amino Z a try, I can confidently say it's become my new go-to protein powder. The taste is excellent, the mixability is great, and the range of flavours available is genuinely unmatched compared to other brands I've used.
What has impressed me just as much as the product itself is the company's commitment to its customers. Their customer service is responsive, and they actively seek feedback to continually improve their products and overall experience. That level of engagement shows they genuinely care about their customers, which is becoming increasingly rare.

If you're looking for a high-quality protein powder with fantastic flavour options and a company that stands behind its products, Amino Z is well worth considering.

Our reply:

Thank you for the incredible review, Oneil! We're honoured to have earned your trust and become your go-to protein. We truly appreciate your recognition of our flavour range, product quality, and commitment to customer feedback and service.

We're grateful for your support, Oneil! If you ever need assistance or have any questions, please don't hesitate to reach out.

Flavour sensations

Great selection of WPI means I will never get bored. The powder mixes well and is not chalky at all. Not too sweet either. Best by far. Grab a few and try.

Our reply:

Thanks, Simone! I'm thrilled you're enjoying the variety, mixability, and balanced sweetness of our WPI range. We love helping customers discover new favourites!

If you have any further comments or if there's anything specific you'd like to share about your experience, please feel free to let us know.

Great flavour and texture as per usual. Best whey protein isolate I've tried. Mixes really well with yoghurt.

Best I have tried
By Tiffany reviewed on 8/06/2026

Verified buyerA verified buyer is someone who has purchased this product from Amino Z

I tried the vanilla flavour the first time I ordered from this brand and it was delicious. I also ordered some sample packs of other flavours and they were delicious too. Then other brands started coming up on my socials so I stupidly thought “oh I’ll try that it’s on sale” what a mistake! Terrible tasting and I bought 3 bags of the horrible stuff! I ended up throwing out the last bag as I couldn’t bring myself to drink it, and instead went back to ordering from Amino Z. I’ve learnt my lesson- I won’t be buying any other brand of WPI from now on!

Our reply:

Thank you, Tiffany! We're honoured to be your preferred WPI brand. It's wonderful to hear you've returned to ua after trying other options, and we're grateful for your loyalty. I'm definitely sharing this with our team—they'll love to hear it!

Once again, thank you for choosing us and your kind words, Tiffany! If you ever need assistance or have any questions, please don't hesitate to reach out.

Very goor
By Hareesh reviewed on 8/06/2026

Verified buyerA verified buyer is someone who has purchased this product from Amino Z

I like the taste of this very similar to chocolates I buy from supermarket. Easily mixes into water or milk to give that super milk shake kind of feeling.

Our reply:

Thank you so much for your feedback, Hareesh! I'm really glad you're enjoying the taste and milkshake-like texture of our WPI.

If you have any further feedback or questions, please feel free to reach out. Thank you once again for your support, Hareesh. We really appreciate it!

Best protein in Aus

10/10 recommend. Nothing beats the flavour + doesn’t have an ingredient list a mile long like many others.

Our reply:

Thanks so much, Finn! We're honoured by the 10/10 recommendation and pleased you're enjoying both the flavour and clean ingredient profile of our WPI!

We're grateful for your support, Finn! If you ever need assistance or have any questions, please don't hesitate to reach out.

Such good flavours
By Suri reviewed on 7/06/2026

Verified buyerA verified buyer is someone who has purchased this product from Amino Z

It’s great that Amino Z has samples you can try before buying one or two. I really love the flavour variation they have to choose from as well! They all tasted delicious that it was hard to choose just one.

Highly recommend the vanilla malt and pandan flavour!

Our reply:

Thanks for the review, Suri. I'm so glad you enjoyed the sample packs and found some flavours you loved. Vanilla Malt and Pandan are fantastic picks! I'll be sure to share your feedback with the rest of the team, they'll really appreciate hearing it!

Outstanding
By Reuben reviewed on 6/06/2026

Verified buyerA verified buyer is someone who has purchased this product from Amino Z

Since discovering this product about three years back, we haven’t used anything else. I’ve got four young guys who come train in my garage gym and all of them now use the Vanilla Creamy for shakes, protein snacks, and cereal toppers. Taste is incredible, blends smooth, couldn’t ask for more.

Our reply:

Thanks so much for sharing this, Reuben. It honestly means a lot!

I'm really glad we've been part of your routine for the last three years. It's awesome to hear that not only you, but also the guys training in your garage gym, have been enjoying the Vanilla Creamy! We put a lot of work into creating flavours that work just as well in shakes as they do in recipes and snacks, so it's great to hear how versatile it's been for you. I'm definitely sharing this with our team—they'll love to hear it!

Thanks for supporting us as a small local business, Reuben. We really appreciate it!
