First Class Protein

Blended with NZ grass-fed whey protein isolate, natural flavourings and without unnecessary fillers, True Premium Whey Isolate is your first choice for lean muscle development and weight management. Savour the clean taste, pure quality and high protein content that makes it easy to digest in shakes, smoothies or as a protein-boost in recipes.

Leading Manufacturing Processes

Our whey protein isolate is manufactured through a combination of both cross flow micro-filtration (MF) and ultra-filtration (UF) to provide an extremely pure and refined protein.

Less Than 1% Carbs/Sugar

The carbohydrates and lactose that are present in normal whey protein are removed in an isolate protein, making it one of the purest proteins in our range.

High in Protein

Whey protein isolate has one of the highest protein contents of any known substance to man. In natural form it boasts 90%+ protein content making it ideal for supporting lean muscle growth.

Fast Digesting

The bioavailability of whey protein isolate means it is quickly digested by the body to provide essential amino acids for fuel or recovery.

New Zealand Sourced

Not all protein powders are made equally, NZ proteins are considered the best in the world due to industry leading livestock processes and strict government regulations.

Rich Amino Acid Profile

Whey protein isolate contains a complete amino acid profile for rebuilding muscle and providing vital nutrition for the body.

Muscle Gain & Performance

Ensuring your body receives a regular supply of protein is essential for supporting lean muscle growth. Protein consists of amino acids which are the building blocks of muscle and allow us to build, repair and maintain muscle tissue.

Building muscle mass essentially involves the process of lifting heavier weights, tearing the muscle fibres and then rebuilding them stronger and bigger and this is where regular protein intake comes in. Current research indicates roughly 2.2g of protein per kg of body weight is required for building muscle. For an 80kg male this equates to 176g/day which equates to roughly 30g-40g per meal spread over 5 meals.

Protein can be attained from a wide range of wholefood sources such as fish, chicken, and beef as well as non-animal sources such as quinoa, green peas and nuts. Protein can also be attained in supplement form, most commonly in powders such as whey protein powder, pea protein powder or rice protein powder. These powders allow for a convenient way to add additional protein calories into your daily diet and assist with muscle building needs.

Weight Loss & Toning

The lowest calorie way to consume protein is in a protein shake. Products such as Whey Protein Isolate have extremely low levels of carbs and fats, meaning the calories you consume are virtually pure protein. If you’re looking to minimise your caloric intake and burn any excess fat, a high protein diet is a must. Not only will a high protein diet ensure your body draws its energy from excess fat stores, it’ll also make sure you don’t feel hungry and crave unplanned cheat meals.

Nevertheless, we wouldn’t advise you rely on protein powder as your only source of protein. Rather it should be used to supplement a well-rounded diet.

The taste of this protein powder is unlike anything I have ever had before! It tastes exactly like a banana milkshake, which is one of my absolute favourite flavours. I am a huge fan, and have purchased this product for a second and third time again already.

What are the differences between is the difference between HASTA WPI90 and WPI90?

Our HASTA range has been independently batch tested for WADA prohibited substances. HASTA formulas are best for athletes who may be drug tested and are looking for added peace of mind when consuming performance-enhancing supplements.

Why have you chosen New Zealand whey protein powder for your formulas?

New Zealand protein is widely regarded as the best available in the market, and superior to Australian and North American equivalents. The livestock processes are of much higher standards and involve the cattle being exclusively grass-fed and exempt from hormone use. Bottom line, this leads to a higher quality raw material with exceptional mixability and taste in the finished product.

How is True HASTA WPI90 flavoured?

We have opted to use stevia to sweeten our flavoured proteins. Stevia is derived naturally from a plant grown in South America and is around 200-300 times sweeter than sugar. We therefore only need very small quantities of this naturally produced sweetener to flavour our protein powders. Our in-house development team has pushed the boundaries of natural flavouring to develop completely unique flavours that contain no artificial ingredients or additives whilst maintaining a fantastic natural taste. Every flavour is made using 100% natural ingredients including the likes of real vanilla, freeze-dried fruits, natural cocoa, organic desiccated coconut and manuka honey.

Suggested Use

Suggested Use

Add 1 Large TP Scoop (30g) to 150ml-200ml of liquid of your choice. Shake and consume. Consume 1-3 servings daily or as required.

True Protein recommends as a guideline 1.5 to 2 grams of protein per kilogram of bodyweight. This recommendation is based on the assumption that your goals are to build lean muscle and enhance recovery. This translates to an 80kg person taking roughly 120g to 160g of protein per day. We recommend that you fulfil this quota through a combination of wholefoods and protein supplementation.
