Cinnamon Swirl- is by far the worst flavor I have ever tried. It has a very strong protein after taste and it isn't easy to mix with. Chocolate PB- I repurchase all the time. It is so good and taste exactly like a Reese's PB cup. Molten Chocolate- great flavor and very easy to mix with!

Cellucor has been my go to protein for a while now. The macros are really good and I definitely feel like my muscles have better recovery. This protein is able to feed the muscles and you wont feel as though your muscles are hungry for more. Price is average. As for the taste, chocolate is by far the best for this protein, it is thick for whey, creamy and smooth. Vanilla is pretty good too but im personally nit a huge vanilla fan but it is still really good. Cinnamon swirl is another flavour that is worth trying. It tastes like vanilla protein with a cinnamon bun aftertaste. I definitely do not recommend the peanut marshmallow as it was a bit of a disappointment. Overall this is a great product and will get the job done!

  • 8 Molten Chocolate

Tastes good but doesnt mix in water. Forms clump when you pour water. Very disappointing. Need a spoon or stirrer to remove the clumps and its a waste of time . Hope cellucor can fix this problem.

I have been using Cellucor's products for quite some time. I bought 4 tubs back when they were the 54 ser. black tubs in cookies n' cream (different website for the sweet promo B1G1) I got tired of it and the oreo cookie crumbs are a bit annoying since they don't mix but sit and turn to sludge if you let it sit long enough. The protein was proficient in doing everything it claims. I recently bought the new Grey tub version 70 ser. in Cookies n' Cream, same issues but a very noticeable difference in overall performance and recovery and this new version mixes 10x better, you still get the annoying cookie crumbs. It is a small ding enough to drop some points because the flavor isn't as noticeable this time around and yes them cookie crumbs. I bought the Cinnamon Swirl and am in love! The first few goes were a bit on the sweet side, but after a full week of using it, I am hell bent on buying only Cinnamon Swirl. Same goes for the Cinnamon Swirl in the new Grey 70ser. Tub Performance and Recovery is insane with this product if used right. I am no longer a hardcore ON fan, Cellucor has won me over with this amazing Protein. I use several of their other products and nothing short of quality. Will buy again!

  • 10 Peanut Butter Marshmallow

If you're like me, just a regular guy (5'8 asian, lactose intolerant) who plays competitive basketball at the park/rec, goes to work, then hits the gym... this is a pretty nice protein that wont hurt your pockets. I loved this. I mixed it with 2 scoops when i was feeling balsy, 1 scoop on non gain days, little (barely none) clumps even when i didnt use a lot of almond/soy milk or cold water. it mixes well, tastes like what it says with no after taste, nothing weird. I was a skeptic, but after a couple of months of use, i noticed great gains (following a chicken salad diet with fish here and there) eat clean and you'll be fine. I do want to add, this makes for a great (10/10) ice-shake (milk, peanut butter, bananas, honey, 2 scoops) !
