WOW! This blends so smooth, no lumps, doesn't have gluggy texture, even with 2 scoops and 200ml almond milk. Choc mint is seriously delicious! Very clean flavour, not super sweet and just the right amount of mint. Reminds me of thin mints (US girl scout cookie!) Can't wait to try Fruitty Cereal.

Incredible. I usually stay away from milk based proteins as they generally contain thickeners, which I don’t like. Super pleasantly surprised by the sample I got in my order! Frozen banana, mixed with milk, tastes exactly like banana paddle pops.This will be my go-to for a milk based protein!

I planned to use it up as a drink after workouts when I don't plan to have cereal but my wife got grumpy having it sit on the bench so I thought just chuck it out and stick to what I like.

Great Protein
11 November 2022

Solid taste and mixes well with water or milk. Love that it’s triple filtered for the most important stuff. A little expensive but it’s got some extra goodies mixed in that make it all worth it. BCAA’s and glutamine. By far my favourite protein, looking forward to trying the cookies and cream (only tried the basic chocolate).

Love this stuff!!
11 November 2022

This stuff, simply put, is one of the best on the market! The flavor is fantastic, mixes extremely well with no chalkiness or separation. I mix mine with water, sometimes a scoop of peanut butter, half a banana and 2 scoops post gym. I have tried many types over the years and this is my go to. Even better, the price is really good on Campus Protein compared to sites like Amazon, M&S, bodybuilding etc. Do yourself a favor and get the chocolate peanut butter.

No frils product, just what I need
25 May 2019

My goals are to build maximum muscle hypertrophy. I'm looking for a pure whey isolate, no fillers, thickening agents, as low as possible carb sugars, I'm looking to feed my muscle rather than my hips. I'm happy to sacrifice taste and mouth feel for protein and nothing else. Your goals may be different. Value for money is also a primary goal, as I'm consuming protein every 2.5 hours of the day. Products I've investigated within the last six months: Mutant Whey 10LB $1.18 per serve Balance Ultra Ripped $1.69 per serve MUSCLEPHARM COMBAT 100% ISOLATE 5LB $1.54 per serve R1 Protein $1.51 per serve MUSCLETECH NITRO TECH CASEIN 2.2KG $1.54 per serve MUSCLEPHARM COMBAT 100% CASEIN 1.8KG $1.98 per serve R1 Protein for me so far is ruling, no other powder I've found has ... MoreMy goals are to build maximum muscle hypertrophy.

At first I thought, hay: this stuff feels very thin in the mouth, but I persisted with it, and it's doing what I need it to do, build muscle, not add fat to the hips. In terms of value for money, it's also the best in it's field. Flavour is acceptable. Also don't forget, if you want to build maximum muscle hypertrophy & minimum fat on hips, drink lots of water, I'm currently on aprx 6L a day, and this is achieving goals.

This is the good stuff
28 October 2021

My trainer got me onto this, and I’ll never look back. Have tried a bunch of flavours; chocolate fudge (yum!), chocolate peanut butter (AMAZING) fruit cereal (yum!) vanilla butter cake (good and super buttery!) strawberry creme (too sweet and not to my taste) salted caramel (tasted weird to me) frozen banana (the only one I really didn’t enjoy, but I don’t like banana flavours so eh) Never bloaty, never gritty, mixes perfectly smooth in just water and works a treat in smoothies. I’m obsessed, can’t wait to try even more flavours!

Truth
27 April 2022

This is absolutely amazing. Took the cookies and cream flavour and mixes so well with milk. Unfortunately I’m on a cut so mix with water but still decent. Out of all the proteins I’ve taken I’ll definitely stick with this for now until I find something better or exactly the same but cheaper. Overall I’ll definitely recommend this hands down.

12 December 2021

We are very pleased with this product! The Rule One hydrolysate is a high-quality, tasty protein supplement. It mixes easily with water or milk, without any clumps or residue. This product contains only pure whey isolate and hydrolysate, with no fillers or additives. It has a rich vanilla flavor that is not too sweet.

Worst delivery experience ever
7 March 2023

I bought two Rule 1 protein powders exactly the same but was delivered 1 natural and one artificially flavoured. We had to drive all the way to the Chatswood store to swap the incorrect powder for the natural Rule 1 powder and received no apology or any explanation. I also paid for express shipping as we had run out and received it almost a week later. Really poor experience and service. It would have been easier to just buy the artificially flavoured Rule 1 protein powder at our local store to avoid all the hassle.
