Whether it’s my monthly subscription, a replaced monthly subscription (it got lost one time…reps were so helpful!), a new flavor of protein to try, or getting in on their special deals, KOS’s brand, service, and quick processing and delivery times can’t be beat!

Taste very good 😊

Amazing brand and service!!!

I’ve sent at least 3 emails to customer service and never hear back. I left a comment on Instagram about this and was told to DM. I sent a message and was ignored again. Canceled my subscription.

Hi KOS team, love the protein powder and we've been buying constantly! The only reason I only gave a 4 stars review is the scooper in every bag/container. I think should be one for one customer and it can be reused. This will minimize waste. I hope your company can make that change. Thank you!

I found the vanilla protein powder to taste gritty and did not dissolve well.

Will continue trying other products KOS has for sure.

helped me with my discount coupon right away.

Easy to navigate and find what I need

Very Simple!!

These are amazing and provide so much energy. I can't do coffee or energy drinks so this is perfect!

Love this protein shake! It really is one of the best tasting protein powders out there and great value, excellent customer service! So thankful I tried it!

Love your products. Great tasting and organic. Superb quality.

Bit sweeter than I'm used to, chocolate nice balance, shipped quick, good packaging.

Easy to order fast shipping if only I would have liked the protein powder I would order again since it was a very simple ordering process.

Shipping is speedy. Packaging is good. KOS chocolate protein is delicious!

Haven’t used the product yet , but ordering and delivery were not a problem.

Bought various flavors and like them all!

ordered the “free samples”
