In terms of protein it delivers as expected, however the taste and mixability could be improved. I tried it with multiple variations (e.g. oats, water, milk, etc.). The sweetness (sucralose) of the product is just too overpowering for my liking. After struggling through this container, I'll be trialing another brand.

Overall, i do believe Rule1 is a fantastic protein with awesome flavours, esp the vanilla and choc fudge, however, what im extremely disappointed with and this is just my personal opinion, others may not worry about it so much, is that upon looking at the ingredient list, they do use 'High Fructose Corn Syrup' and 'palm oil.'Its for that reason i wont be purchasing Rule1 again.

Horrible, tasted like squashed ants. For breakfast I have been using Chocolate flavoured protein on cereal for over 20 years and tried many different brands. My son now also has protein powered on his weetbix. I have been happy with lots of different brands but settled on Syntha 6 Edge Chocolate MIlkshake I buy in the 100 serve bags. Unfortunately it was not available for a while so I switched to Sythna 6 however my son wanted to try different things and over the last 6 months bought 6 different proteins that he gave me as he found he preferred Syntha 6 Edge that is available again. I finally used up the last one two weeks ago and was happy to start on the Syntha 6 Edge againLast week he said I bought a different protein to use but I hate it so I will give it to ... MoreHorrible, tasted like squashed ants.

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.

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).
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.
When someone drops a pan of Philly Butter Cake in my lap I am like an2 year old at Christmas....Whivh is why,’when I saw A vanilla butter cake flavor powder here I had high hopes it would be super good. I’ve never had R1 protein so it was a new brand for me from the get go, and based on other reviews I figured it was worth a shot. Sadly the flavor just isn’t for me. I get the vanilla and the cake parts, but it’s missing that buttery salty aspect. I even tried grinding a pinch or two of salt into my shake to see if I could round out the flavor. It helped a little. For 37.99 the flavor is a little “artificial” and doesn’t necessarily represent as advertised on label. But, the profile fits my cutting needs so that is certainly a bright spot. I’m sure R1 has solid ... MoreWhen someone drops a pan of Philly Butter Cake in my lap I am like an2 year old at Christmas....Whivh is why,’when I saw A vanilla butter cake flavor powder here I had high hopes it would be super good.

Previously Gold standard Isolate was my go to for protein, however I chose to try this as it was out of stock at the time. Sure glad I did.Mixes well, ChocPeanut butter Tastes great! It also some how feels lighter in the stomach compared to other more expensive isolates. My new go-to every time I need to restock.
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 serveBalance Ultra Ripped $1.69 per serveMUSCLEPHARM COMBAT 100% ISOLATE 5LB $1.54 per serveR1 Protein $1.51 per serveMUSCLETECH NITRO TECH CASEIN 2.2KG $1.54 per serveMUSCLEPHARM COMBAT 100% CASEIN 1.8KG $1.98 per serveR1 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.
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!
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.
