Customer Reviews
Cool & Calm spray is pretty good
tried the Cool & Calm oral spray and it's actually quite effective for winding down without any melatonin. it's a bit annoying that you can't combine discount codes with the bundles, but the quality of the product makes up for it. way better than some other brands i've tried.
Consistently good experience
I've ordered from Stack Supplements a few times now, and they're always reliable. This last time I got the Immunity oral spray. Delivery took about a week to get to me in Arizona, which is pretty standard for them. The spray itself works as expected, just like the Fast Focus spray I got previously. It's nice to know what you're getting.
Decent products, shipping was okay
I picked up The Night Stack bundle during a sale, primarily for the Sweet Sleep and Cool & Calm sprays. The products themselves are effective; I've noticed a real difference in my evening routine and unwinding before bed. The spray format is convenient and absorbs quickly, as advertised. However, shipping felt a bit slow, taking 8 days to reach my address in Florida. It wasn't a critical delay, but I've had faster service from other online stores. The packaging was secure, and everything arrived intact. Overall, good products, but shipping could be a tad quicker.
Good for sleep, easy to use
So I decided to try the Sweet Sleep oral spray because my friend kept talking about it. Ordered it online, and it showed up maybe five days later? Super easy to spray under your tongue before bed. I definitely felt like I drifted off quicker. No weird aftertaste or anything, which was a plus. It worked out pretty well for me.

Share tips, ask questions & help fellow shoppers save more
Hey, wondering if anyone knows how long shipping usually takes to, say, California? Need some sleep spray kinda soon.
Can you stack discount codes on this site? Got a first-time buyer one and saw a Black Friday deal. Wondering if I can combine them.
Anyone tried their 'Sweet Sleep' spray vs. something like Hims sleep gummies? Curious which one is better.
I saw an ad for 15% off but it disappeared. Is there always some kind of first order discount or was that a limited thing?
How many sprays are in one bottle? Just trying to figure out how long a single bottle of the focus spray would last.
