Giovanni G.
Sample pack review

Jared, I wanna start by saying I am a first time bodybuilder going through my first prep. I’ve been using the same protein powder for the past 16 weeks using 1/2 a scoop a day. I purchased this sample pack because I needed change and didn’t want to spend the money on a full tub. The sample pack absolutely blew me, the different flavors and options was something I didn’t know I needed until I dove into it. The coconut cookie one and the glazed donut one absolutely blew me away. I will be ordering full tubs of both after I finish my next 2 sample packs, yes the sample packs were that good I ordered 3 of them, I’m on my second one now. Didn’t know what to expect but buying the sample pack was the best decision I’ve made throughout this whole prep.

I'm glad that you liked the sample pack enough to order a full tub! I think that it's great that you can also use the different flavors to help you stay on track with your protein intake Giovanni!! Good luck on the prep :)

Great stuff!

Loved the convenience of the single serve packs so I could figure out which flavor was my favorite. I’ll be ordering the caramel coconut cookie for sure!

You gotta try them all Stace!!! Caramel Coconut Cookie is a popular option for sure :)

Sample pack

Personally, I really liked the caramel coconut cookie and glazed donut. Every other flavor tasted pretty much as you would have expected. Not horrible, but no other standout flavors.

Thanks for the review Tye! We're so glad you liked those 2 flavors so much!! We appreciate the feedback. :)

Thank you for your review Emily!!

Amazing Taste

With so many options of protein powder out there it comes down to taste for me. These flavors have exceeded my expectations. I also appreciate the fewer calories they have compared to most powders. Very good very clean protein. Will definitely keep buying this.

Thank you for your review RC! We are so glad that you enjoy our flavors and appreciate the clean protein they offer. Welcome to the family!! :)

Not what I expected

I purchased this in the hopes of having some good flavor in the protein itself. I have invested tons into supplements over the years including protein powder and well not sure if I will purchasing any one single flavor after this sampler pack. I was really not overwhelmed by any one protein in particular and honestly expected more....

Thank you for your review. Sorry we didn't meet your expectations :(

Isothority samples

I have not yet tried banana or chocolate but I can say I enjoyed strawberry, blueberry, vanilla shake, peanut butter chocolate and carmel coconut cookie but the rest of the flavors didnt really enthuse me. I will probably stick with carmel coconut cookie and may buy the peanut butter to mix it up. Nothing tasted bad, just some better than others. I like to mix these with milk to make it feel like im drinking a milkshake vs a protein shake.

We're glad you enjoyed most of the flavors Jamie!!! The variety is the reason why we love the 9 pack so much!!! Thanks so much for your review!!! :)
