Customer Reviews
Love these shakes!
Oh my gosh, I just tried the Mocha Latte and it's incredible! I've been searching for a good iced coffee that's also high in protein, and this totally hits the spot. The flavor is rich, and it doesn't have that weird aftertaste some protein drinks do. It arrived super fast, too. I'm definitely going to get more, maybe the Variety Pack next time! You have to try these!
Absolutely love these shakes!
I just received my Energy Variety Pack and oh my goodness, these are amazing! The Mocha Latte is seriously so good and gives me the perfect boost without any weird aftertaste. I'm so glad I tried these. I'm definitely going to subscribe for regular deliveries. You guys have a customer for life!
Good deal on a case
I was looking for a high-protein drink that wasn't too expensive. I found Slate Milk and bought a case of the Classic Chocolate Milk. The price per shake was good, especially with the first-time buyer discount. Shipping was free too. Felt like I got my money's worth.
Smooth ordering and quality product
I decided to try Slate Milk after seeing it pop up a few times. I ordered a 12-pack of the Vanilla Latte. The website was clear, and checkout was straightforward. I received an order confirmation email immediately, and a shipping notification with tracking within 24 hours. The package arrived in excellent condition about five business days later. The shakes themselves were well-packaged, and the product quality was excellent; the Vanilla Latte has a nice flavor without being overly sweet. It's a convenient, low-sugar option that actually tastes good. I appreciated that they don't need refrigeration until opened, which made storing them easy.
Good value for a first order
As a first-time buyer, I was looking for the best deal. I got a good discount on a case of the High Protein Shakes, which made the price per shake very reasonable. Shipping was free too, which was a nice bonus. It felt like a solid purchase for the price, especially considering the protein content and being lactose-free. Definitely worth it for what I paid.
Always a solid choice
I've ordered from Slate Milk several times now. My first order was a trial pack, then I moved to subscription for the Mocha Latte, and this time I tried a case of the Dark Chocolate Milk. The quality is consistently good. Each order has arrived on time, sometimes even a day early. Their high protein shakes are a staple for my mornings. It's nice knowing exactly what I'm getting every time.
Quick delivery, good product
Bought a case of Dark Chocolate Milk. Shipped fast. Tastes good. Lactose-free, which is key for me. No issues.
Good product, minor shipping issue
I ordered a case of the Classic Chocolate Milk and it arrived pretty quickly, within four days. The milk itself is great, exactly what I expected – good flavor and no lactose issues. My only small complaint was that one of the cans had a tiny dent, not enough to leak or be a problem, but it was there. Overall, I'm happy with the purchase and the value.
Decent shakes, minor issue
I got a case of the Vanilla Latte. The flavor was pretty good, and I like that it's lactose-free and low in sugar. It definitely helps with my protein intake. Delivery was fine, arrived when expected. My only small gripe is that a couple of the cans had slight dents, not enough to leak or anything, but it looked a bit rough. Overall, a good product and I'll probably order again, but maybe they could improve the packaging a little.
Decent shakes, easy process
I grabbed a Variety Pack to try a few flavors. Ordering was super easy on their site, no fuss. The shakes showed up a few days later, which was pretty standard. The French Vanilla Shake was my favorite, the others were okay. Nothing groundbreaking, but a solid high-protein option for when I'm on the go. Pretty good experience overall.

Share tips, ask questions & help fellow shoppers save more
Does Slate Milk use artificial sweeteners? Can't stand that aftertaste.
Does anyone know if Slate Milk is actually lactose-free? My stomach is super sensitive to that stuff.
Any word on how easy returns are? Ordered a variety pack and didn't love all the flavors. Just wondering if it's a hassle.
Hey, thinking of trying these out. How long does shipping usually take to, say, California?
Thinking about getting some of the iced coffee flavors. How do they compare to Fairlife, taste-wise? Fairlife's my usual.
