SLEEP XT is formulated to help you recover, repair, and rebuild; by falling asleep faster and staying asleep longer.
Sleep is one of the most underrated aspects of your health and physical performance. Sleep plays a vital role in building muscle and also aids in losing body fat.
SLEEP XT blends ZMA, Melatonin, 5-HTP, L-Theanine, GABA, L-Leucine, and Maizinol.
GABA, 5-HTP, and Maizinol have a powerful effect on improving your sleep, by helping you feel more relaxed, along with decreasing stress and anxiety. L-Leucine taken before bed has been shown to boost muscle-building hormone production as well as accelerate the body's ability to recover during sleep. ZMA has been shown to increase testosterone levels naturally.
SLEEP XT leaves one feeling rested, recovered, and ready to take on the day and go after your goals.
SLEEP XT™ is a unique combination of ingredients designed to support relaxation and deep, restful delta sleep. With delta sleep, comes critical regenerative activities that include increased Growth Hormone, and optimal Testosterone release. Paired with activation of the mTOR muscle-building pathway via the ingredient leucine, SLEEP XT is the perfect nighttime recovery formula.
SLEEP XT can be used by both men and women who want to push their fitness results 24-hours a day. The formula is designed for highly active people in and out of the gym that either want to optimize their sleep and muscle recovery, or those who simply struggle with regular sleep.
As the name of the product alludes to, SLEEP XT is used to maximize sleep as well as protein synthesis and hormone balance for muscular recovery.
Mix one serving with 6-12 ounces of water approximately 30 minutes prior to going to bed. It is recommended to start with half of a serving to assess your tolerance. Do not exceed more than one serving per day. Do not operate any heavy or potentially dangerous equipment while using SLEEP XT. SLEEP XT can be mixed with cold or warm water, based on your preference.

So I buy a lot of shawstrength products and this is the first one I can't do. Even less then half dose I wake up at 3 am kicking my legs. Then at 6 am like I was hit by a truck hauling whiskey. The other supplements I've bought and still buy are amazing. I will say this is a me problem as I gave it to my wife and she slept fantastic.

I don't like this supplement, but that's my fault for not noticing it had melatonin in it. It DOES make you fall asleep, which I like. But, it actually makes my sleep much worse, I'm waking up every 1.5 to 2 hours, during the time I am asleep, its a very light sleep, and I wake up very groggy the next day. I've never liked any melatonin supplements, so I'm not surprised I don't like this. I think if they made this minus the melatonin I would like it, as I've tried most of the other ingredients for sleep before and liked them. If you like or even just don't mind melatonin, I'd highly recommend this stuff. The taste is pretty good too. My experience would warrant a 1 star review, but I gave it 4 stars because it is a good product and does what it says it will do, but again, it was my fault for not reading more carefully before ordering.

Amazing sleep
John B. 5/5 Verified
I work night shift so getting sleep during the day can be hard sometimes. But since I started using sleep xt I sleep great. Sometimes a little to great. I also have started using it on my off days because my sleep schedule is messed up I wake up in the middle of the night & cant fall back asleep but when I use sleep xt I get my full night's sleep. I will continue to buy this product. The taste isn't my favorite but its also not something that is a deal breaker.

So far so good….a man jumped off the 10th floor. On the way down as he passed each floor he was heard saying “so far so good!” 🤣

It's the only ZMA liquid supplement that I have enjoyed. Normally I take it in pill form so its noce to be able to have other options. You could probably skip the food dyes and it would get a better review.

Awesome product, a bit hard to fully incorporate into water but when it works it works!

My hubby has noticed how much better a nights sleep that he is getting and how more awake he is at work.

I've been shopping on Brian's sites for over 2 years now. I love all the products I've bought. I've never been disappointed. The proteins and the other supplements are amazing. The gear works wonders, and clothing line is awesome too! Also, the protein crisps...to die for :)

The Sleep works amazing for me and I use it in combination with CBD. I always wake up feeling refreshed and recovered when I use this after a hard training session. I plan to keep buying this.

As an Athletic Trainer for 30+ years and highly critical of most supplements, I love your products. My nephews who play football in high school are now taking your Creatine and BCAA’s.

Works great but tastes terrible. Just me I’m sure I hate anything lemon lime flavor. Think strawberry
Myron R. 2/5 Verified
Wow! This has been the product I have been searching for. I have tried so many sleep aids and I couldn’t find anything that could shut my brain off and get me the rest I needed. I have tried probably 10 different products over the last 2 years before I got to this one. Having this in the nightly routine has become a must for me. I am so happy that this product works, and to make it better its quality ingredients! The flavor is great! Tastes like a lemon head candy almost. Super happy the Shaw Team created this! Thank you!

I use sleep daily. It is the only thing that will get my 55 year old body to sleep through the night! I wake up refreshed and ready to go in the morning. When I do not take it I am up 2-3x per night to go to the bathroom. SLEEP XT is the best sleep aid I have tried....and I have tried dozens.

I have only been taking Sleep XT for a few days. I have no problem falling asleep, but I wake up several times a night, being old isn't fun. While I still wake up several times a night, I definitely feel like I fall back asleep faster and don't stay awake as long, since starting Sleep XT. Definitely helping me.
