What Are Our Sleepers Saying?

★★★★★

I'm still in disbelief

I've had seemingly unsolvable sleep issues for years. I've tried every possible known remedy, and some very random/questionable unknowns - to no available. After so many years - I simply resigned myself to living with chronic sleep problems (and all that goes along with that). Lo and behold - this stuff actually works. I fall asleep fast, sleep through the night, and am not groggy in any way/shape/form the next morning. Pretty amazing.

★★★★★

Helps me stay asleep all night

This product helps me stay asleep all night. I feel fully rested in the morning.

★★★★★

It works!

I’ve gone from sleeping 3 to 4 hours a night to now sleeping 6 to 7 hours. It may not seem like a lot of sleep to some people, but for me it’s a HUGE improvement.

★★★★★

Incredible Sleep Aid

Since I started using CS2, I am enjoying 7 1/2 to 9 hours of sleep per night. Thank you for this wonderful product. At 69 years old, I thought I was doomed to 5 hours a night. Not any more! I tell all my senior friends to try this and enjoy sleeping again.

★★★★★

Tastes great

love the flavor, not too sweet but still tasty, look forward to it every night

★★★★★

Great Taste and It Works!

★★★★★

Love this product!

Love this product. Much better sleep and the taste is great!

★★★★★

Sleep better

I’ve been adding CS2 to my stack the last 2 months. Noticeably better sleep and tastes great too!

★★★★★

Love the ingredients!

I have used many relaxation/sleep supplements. I really like this one. It combines great ingredients in a tasty, easy powder. Just mix with water, enjoy and sleep! These ingredients have many other health benefits as well.

★★★★★

Absolutely effective!

After using this product for a couple of months and giving it to my wife to try I am convinced it has a range of ingredients at an effective dose that can address sleep onset, sleep duration and sleep depth.

★★★★★

CS2 - The Real Deal

CS2 is a product that you can be very comfortable taking. It has great ingredients. An added bonus is that it blends so well and tastes good. Highly recommend.

★★★★★

Game Changer

I have tried other sleep drinks, but this has all the best ingredients. Sleeping great!

★★★★★

I like it.

I like the powder form. Mixes well and easy to take as a shot before I start my evening routine. Thank you.

★★★★★

Awesome sleep supplement

It has made an impact on going to and staying asleep. Easy to take. Recommend!

★★★★★

This Stuff Works

I noticed it the 1st night but after a week it does get even better. I like that it's a beverage vs a pill, as pills take longer to digest and get into your system. This is like an infusion. Love it.

★★★★★

CS2 is a game changer

It combines all the sleep ingredients I used to take separately into one drink that tastes great. My sleep is deeper, recovery is better, and I wake up ready to go. This is definitely my go nightly routine while at home or traveling. Single pack servings are awesome.

    Working so far.

    This is the 5 th sleep aid I’ve tried and they all seem to kinda work for a while until they don’t. So far this seems more effective than anything else I’ve tried. Fingers crossed.

    More restful sleep, less waking up

    The CS2 Sleep Drink has made a huge difference! I have been drinking one packet each night about 30 minutes before bed I am not waking up as much during the night. When I do wake up, I am able to go back to sleep (instead of tossing and turning for two hours before finally falling back to sleep). I have tried so many products, and melatonin does not work well for me, so I had about given up. CS2 works!

    Great Product

    I've started taking CS2 consistently every night for about a week now. The results have been pretty good and I believe they will only get better. I still have early morning wake-ups around 3-4am, but I'm able to fall back asleep much faster than I was previously. Looking forward to keeping this in my nightly routine.

    This might be the thing

    I’ve struggled for decades with insomnia and have taken different combos of drugs, OTC and prescription over the years. I’m in my second month of CS2 and I’m off all but a small dose of one prescription. I’m hoping to get rid of the last one eventually. Best sleep I’ve had in a long time. I’m super happy so far.
