Best Value Quality WPI

originally posted on bulknutrients.com.au

- Fantastic customer service- Super quick dispatch and delivery- The protein powder mixes really well- No added nasties- Great for adding to baking/cooking- Perfect for those with Type 2 diabetes- Great taste and long shelf lifeI can't say enough great things about this product. As a dietitian, I recommend this product (and several other Bulk Nutrients' products) to many of my clients. I miss this product together with the collagen peptides in my morning shake. Yum!

His trainer had told him he needed to up his protein and we had tried a few brands but most he couldn't stomach.I had tried Bulk Nutrients WPC in the past and liked the flavors and I had heard great things about WPI, so I purchased a bunch of different flavors and my partner was hooked. I'm buying 5 more KGs, and were going to try both WPI and WPC, mix it up a little and see how he goes.This really is a great brand, he's doing so well and he's managed to stay on track because he looks forward to having his protein.

Bulk Nutrients have created an awesome range and I can see us purchasing from them for the rest of our lives.It's definitely worth trying. :D

Great Basic Need for Muscle Building

Ive tried many sorts of protein powders and this by far is my favouriteFirstly the taste is not overwhelming, not boring, so i can say its in the middle.Then the way it dissolves is quicker than others. Other brands after drinking it, u will still see lots of residue left clinging on the container. Whilst this brand does dissolve better. Which means it probably dissolves better inside your body.And Lastly i notice great muscle gains when combined with great workouts.

Great Value WPI with huge selection of flavours
16 September 2023

Pro: large selection of flavours, excellent quality protein powder, excellent value for money, Mixes easily, great packaging.Cons: use of artificial sweeteners maybe a con for some. Sweetness is very high which makes it taste a lot like candy when just mixed with water, which is a little bit sweeter than I desire.Overall a fantastic product just wish they would tone down the sweetness by 20%. P.S. Choc honeycomb is the best flavour really does taste like a violet crumble

I recently ordered your protein
25 May 2023

I recently ordered your protein powder and I have to say, I am thoroughly impressed with the quality of the product. I purchased both the vanilla and honeycomb chocolate flavors and they both tasted absolutely amazing.The vanilla flavor was perfect for my morning smoothies and added a delicious sweetness to my breakfast routine. The honeycomb chocolate was a perfect treat after a long workout and satisfied my chocolate cravings without any guilt.Not only did your protein powder taste great, but it also mixed very well and did not leave any clumps or chalky aftertaste. I appreciate the fact that your products are made with high-quality ingredients and are free of any unnecessary additives or fillers.I would definitely recommend your protein powder to anyone ... MoreI recently ordered your protein powder and I have to say, I am thoroughly impressed with the quality of the product.

Must have!
22 February 2023

I've bought the WPI every time I've ordered and I'll definitely stick with it! I have to say, I'm very lucky that I went with bulk nutrients for my first protein powder bc last time I put my order through, post Australia had delays to Western Australia. I tried the Coles brand one to tide me over until my delivery arrived. I really should have ordered sooner! Omg that thing tasted disgusting and the texture was terrible. Bulk nutrients WPI IS FAR BETTER! I've heard of other brands tasting disgusting and I was really surprised bc I've only had BN, so I didnt know how bad it could be! It mixes well and all the flavours that I've tried, I have liked. The first time I purchased, I thought I'd stick with plain old vanilla, but the other flavours are great and they're not ... MoreI've bought the WPI every time I've ordered and I'll definitely stick with it!

I don't know how they could get vanilla wrong and I had to use extra scoops to get the same amount of protein so it worked out expensive.No need to bother with other brands!

My 80’s childhood has come back to haunt me
28 January 2022

Do any of you remember Trim? Trim was the milk my mum would drink when I was young and it was like the first of the low fat milks. Like all version ones of things they hadn’t quite nailed the recipe and on the rare occasions that the rest of us boys in the house had drank all the full fat milk I would be forced to have Trim with my Coco Pops of milo. To my memory Trims recipe went like this.Step 1. Take a litre of milk and tip 950ml down the sink.Step 2. Pour the remaining 50ml into a 2L milk container.Step 3. Fill 2L container with water.Step 4. ConsumeSo what am I getting at?I firstly purchased the WPC from here and loved the flavor and creaminess of the protein powder so thought lets give the expensive stuff a try. I went and fired up the laptop and clicked ... MoreDo any of you remember Trim? Trim was the milk my mum would drink when I was young and it was like the first of the low fat milks.

I went and fired up the laptop and clicked away and bought to bags of the WPI and about 2 days later my package arrived all the way from the apple isle to my front door. I was excited I opened up my favorite flavor (Vanilla Maple), added some cold water and consumed…… Regret set in. Its my 80’s childhood come back to haunt me. Well needless to say Im stuck with this flavored Trim equivalent for the next month or so as I deal with childhood demons and as my mum R U ok. Do you have a stiff drink when you think about your mid 30’s when you were told fat was the enemy and this low fat white substance is your key to skinny thighs?Anyway I digress. This stuff is not for me.Will be going back to the WPC after this. I know its not as refined but neither am I.

Raw Unflavored
8 October 2023

I get the Raw Unflavored for the purpose of Mixing. Whether it is to add extra Protein to my morning Thermowhey Shake or to add Protein to my Overnight Oats. Either way, it mix's well and doesn't compromise the flavors from the Thermowhey Shake nor whatever flavor of choice for the Overnight Oats. Be it Mixed Berries Delight, Banana Bread or a number of other Overnight Oats Recipes. How about a Protein Iced Coffee? Super good. Or feel like a Desert, how a about a Protein Ice Cream? Mango Creme is good.

Wpi
23 July 2023

Recently decided to try bulk nutrients wpi both chocolate and vanilla flavours. Mixing with water the taste is less then average this is a very watery blend which gives you the impression it lacks what it says on the lable. Having mixed other brands with water with sucess both taste and consistency its true you definitely get what you pay for! Further more it should be explicitly stated in the product discription that this wpi is sourced from the USA instead of being some what hidden ie information found on the Q and A not in the description if the product. If you have a quality wpi sourced at the highest quality you would definitely market its origin!! I was disgusted to read my package when i recieved it that it contained 0% Australian ingredients... buying from ... MoreRecently decided to try bulk nutrients wpi both chocolate and vanilla flavours.

taste and price
3 June 2023

I have been drinking same brand of protein for the last 10yrs at least. But due to rising cost of this particular brand, I've decided to find alternative cheaper brands with the same amount of protein or higher. After researching and talking to friends, I've decided I'll give Bulknutrients a go. So, I bought 5kgs of WPI in different flavours so I can pick my favourite. I love the packaging how easy and neatly rip it open. Also, the scoop has longer handle than some(maybe can make a little stiff). Overall, I think I found my new protein brand and it is proudly made locally here in Australia. Pls note, I've given it 3stars for effectiveness and value for money due to I've just started drinking this brand not long ago. So I'm just being honest with my review. Thanks Jo
