USA Whey Protein Isolate
Our USA Whey Protein Isolate is our most economical WPI. It comes in natural flavour or in one of our organic flavours. It is available in 1kg bags to keep larger purchases fresh or you can save big with purchases of the original manufacturers 20kg WPI bags. Both size bags can be bought with our Bulk Buy Discounts. However, discounts only apply for the same flavour unless you buy our 4kg Multi Organic Flavour Pack.
The only wpi I use

Have been using this protein supplement strictly since 2013, i use 1 scoop 1 hour pre workout and 1 scoop post workout, this allows me to get that extra 50g or so of protein that i struggle to get in from food due to busy schedule. Favorite Protein on the market can add any flavourings to it sometimes just blend it in with some fruits or mix some organic honey with it.
Best quality/price WPI

Have been using this product for several years to great effect. I love to mix 40g into a bowl of Chobani yogurt and consume just before bed for a great protein boost. Don't bother with the flavourings - go natural!

This is my preferred protein supplement for my competition level olympic lifting training. Reliable, lean, easily dissolved in milk or water, I drink 4-6 scoops a day to supplement a meat, greens and water diet.

Very smooth and easily added to a variety of drinks or cooking. This is a good value option. First time user, I'm ordering again
Only the best

Ive been exclusively using Professional Whey for more than 3 years and keep coming back because of the excellent quality and reasonable pricing. Can recommend to ANYONE who is looking for a high quality whey protein minus all the bogus BS that some other manufacturers add to theor protein.

Product is excellent. Unflavoured is easy to mix and drink.
Shipping is crazy fast.
Best price and service around, repeat purchases are a no-brainer.
Best bang for buck

I've used several flavours of this great protein. Quality product at a fantastic price especially when compared to local in store buys! Overnight delivery at a fixed price is just a bonus!

If you asked me 6 months ago would I fight a kangaroo in a fist fight, I would of quickly responsed with a "NO" and gone down the crevasse of my bed and gone to my happy place, with my fiancee following that up with a bathing in lemongrass essential oils and warm water.
Once I discovered USA Whey my whole life changed. I now sleep on a bed of nails, I fight kangaroos for a living and have the most unbelievable sex life. Thank you professional whey you saved me externally and internally
Why would you want to buy an overpriced commercial protein?

Why would you want to go and buy a "branded" protein powder that is oozing fillers and fake chemicals. This protein powder is amazing. All natural, good quality and well priced. You can't get much better than this.
Wish I found this sooner!

Just switched over from vanilla to cinnamon after reading a review below and i cant believe that there isn't any artificial crap in this! Whenever I have a sugar craving I drink one of these and I'm good.
Love it, love it.

The USA WPI has been a staple 3 or 4 years now. I love that it is all natural and contains no artificial sweeteners. Recently, I have combined the unflavoured WPI with Professional Whey Organic Cinnamon for extra flavour, along with PW Dextrose post-workout. This product is a must-try if you want a high-quality, pure protein.
