Kill Cliff Opiniões 

Ordered directly from their website and it was promptly shipped.

Ordered at 11:30PM and received our order at 7:00AM the NEXT DAY!!! Stellar business KILL CLIFF! Thanks

Ordered directly from Kill Cliff. Fast and free shipping! I love to drink this during and after a workout to maintain hydration and help my recovery. It is a relatively clean drink that also supports a cause that is very important to me.

Great product and Awesome cause!!! Blood Orange is the bomb!!!! Delivery is super fast. It's awesome that part of the proceeds go towards the Navy Seal Foundation.

Easy ordering and fast shipping! I don’t think the process could be any better!

Fast delivery!! Great product!! Can’t beat the flavor!!

To be honest I was skeptical, I've tried enough products to know they generally do not do what they say. If they they do help performance, there is something that makes them unpleasant, like caffine, flushed skin, tingling etc. But, after a nine mile run for distance and the next day an 5 mile run with hills, the product did exactly what it claimed - no quit. I ran with pleasure - not missing the normal low gut feeling of not wanting to keep running. I will be using these products this year for two Spartan Trifectas.

Received the email to write a review before I even wore the shirt... I can now say that I have worn the shirt and...

Hit a 30# PR on my sumo deadlift 3 rep max...? Must be my new KC shirt! Two of my favorite brands collaborating for one epic shirt... Can’t wait to see what happens when I wear the tank!

Seriously though, the shirt fits as expected. Proud to support these two spectacular brands. ❤️

Love these, orange is my favorite with lemon lime close second. I have one every morning 🧡💚 not happy Vitamin Shoppe and GNC stores no longer carry 😭

Can’t beat free shipping and subscription service. Thanks guys.

Your website is so slow, it took me nearly a full workday to order a shirt. I'm sure the shirt will be 5 stars, but it's worth a few more dollars a month to upgrade the server so customers can make orders in a timely manner.

The product is a little pricey, but for the quality and free shipping I have no problem ordering more. The recovery drinks are top of the line!!!!

All of the recovery drinks are the best. Great product and excellent after a hard workout!

I bring KC regular and Endure on hunts, range training days, and just plain old PT days. My clients love it and I love it. K. Leng is my go to rep. Call her and get set up if you're a business. She's on top of it.

Kaitlin Leng KILLS THE QUIT! Always takes care of CrossFit Windy Hill and our addiction of Kill Cliff.

all of our cases we received are almost expired.
