Customers praised this box as "incredible value" with varied supplements including protein, pre-workout, and energy products. Many said they exceeded expectations and would "100% buy again." Some concerns noted excessive caffeine products and occasional samples/underdosed items. Fast shipping and personalized touches like request accommodations impressed shoppers.
Loved it so much, I came back and got a second! Definitely value for money. Will 100% buy again.
Thanks so much for your review Georgie. We're stoked you liked your Mystery boxes!
Please do not buy this expecting to get your moneys worth. Most of the products I received were samples or overpriced to give it the appearance of good value. The only substantial thing in the box was a pre workout, so under dosed you are better off not taking it and some under dosed electrolyte gummies
Was very pleasantly surprised with the contents of the box - more than I expected! When I make my way through it I'll be grabbing another.
Thanks for your review Cameron! We're stoked the Mystery Box over-delivered 🔥

Thanks so much for your amazing feedback Kylie! We're glad we could help out with your request and that you enjoyed your Mystery Box ❤️
I was shocked with how much value I actually got out of the mystery box, I would say this is a must by if you're low of everything and need a stock up. I'm so happy with what I got and how fast I got it, will be buying from here and this deal again!
Thanks for your awesome feedback Jasper! We're stoked you enjoyed your mystery box! 🙏
Thought I would try the mystery box as it wasnt that much and I got a PWO, BCAA, Energy Drinks, and protein bars. Great value for money and a nice time to try out other brands and supplements that you wouldnt usually buy.
We were stoked to hear this Brian! Glad you enjoyed the Mystery Box.
This is a must buy for value and a great way to try some other product
We're glad you though so Duncan!
Mystery box was good value for money but every product of note was just caffeine. More variety would be great
We appreciate your feedback and we're sorry you felt the box didn't provide enough variety Curtis. These boxes are different every time but we do make mention of some of the contents in the description. Generally the more expensive boxes offer more value and a bigger selection so keep an eye out for the next one!
