What Our Customers Are Saying

Customers overwhelmingly praised the WPI sample pack as a convenient, cost-effective way to explore flavours before purchasing larger bags. Many enjoyed the taste, smooth texture, portioned sachets and versatility in shakes, smoothies, oats and other foods, while also finding them useful for work or travel. Vanilla Maple, salted caramel, cookies and cream, and chocolate received frequent mentions. A small number found certain flavours overly sweet or artificial, experienced occasional mixing issues, or wanted more flavours included.

I've enjoyed trying different flavours. Super handy when you are on the go. I wish I'd received the coffee flavour; I'm keen to try it in a trial size.

A great way to try a few flavours before buying the big packs. The protein mixes well and is very smooth. Love the vanilla and the banana flavours the best.

Fantastic service 👏

Type 2 diabetic who isn't a big meat eater here. Thought I'd try flavoured low carb protein powders. Did some googling - the Bulk Nutrients WPI sample pack popped up. For me, most of them tasted the same, with the exception of banana, vanilla maple & chocolate honeycomb. The others tasted fine, just not significantly different. The before & after sales were FANTASTIC. I cannot say enough about how great the responses to my frequent & dumb queations were. Have purchase the 1kg of the honeycomb & vanilla maple flavours. I'd like to get small packs of the flavours that were not in my sample pack to try. It would be great if that could happen eg purchase a min of 7 of flavours you want to try

Nice options

I found all these to be a bit to sweet for my tastes, so I mixed them with either coffee or unsweetened coffee to cut through the sweetness a bit. Vanilla worked really well with the cocoa and it will be the one I buy more of. Very easy and convenient to use.

Really nice flavours my Husband and I love them and it’s good to have a different flavour handy for when your on the go it’s so good and the protein powder doesn’t leave that yucky aftertaste which I’m really happy about wouldn’t highly recommend this product to my friends my favourite is definitely the salted caramel can’t wait to order more

Don’t buy 2 packs

WPI Sample Pack 7 Pack - Mixed Flavours

Jeremy W on 31/08/2026Verified buyer

I bought 2 sets of the sample packs since the description suggested it was a way to try all the flavours and there was a discount when buying more than 1. Unfortuntely both sets had the exact same set of flavours making it a waste. Would definitely suggest only buying 1 if you want to try. Product is otherwise good overall, most flavours are mild and not too over the top.

Great First Experience with Bulk Nutrients

WPI Sample Pack 7 Pack - Mixed Flavours

Joseph C on 23/08/2026Verified buyer

I recently placed my first order with Bulk Nutrients and unfortunately, the protein samples arrived damaged and had burst during transit. I contacted their customer service team by email, and I was really impressed with how quickly and professionally they handled the issue. They sent out a replacement sample pack straight away, and it arrived within just 2 days. Things can go wrong during delivery, but it’s how a company handles the problem that really matters. Bulk Nutrients’ customer service was excellent, and I really appreciate how quickly they sorted everything out. Very happy with the service and I’ll definitely be ordering from Bulk Nutrients again!

Great Flavours

Sample pack covers everyone’s taste and made it easy to choose large bag! Always have a sample pack on hand to add to baking etc.
