Stack is AMAZING
I've tried so many supplements and honestly nothing has worked like this. The quiz is actually thorough and the results show it. Energy is UP, recovery is UP, sleep is SO much better. Can't believe it took me this long to find this brand.

Best decision I made this year — HANDS DOWN
Three weeks in and I already feel the difference. My morning energy is COMPLETELY different. No more dragging myself out of bed. The personalization through the quiz is what makes it work — it's not just a generic multivitamin. Stack actually thought about what MY body needs.

A genuinely thoughtful supplement brand
I've been on a health optimization journey for about three years and have tried what feels like every supplement brand on the market. Most of them are either generic multivitamins dressed up in pretty packaging, or they're so specific that you need to be a nutritionist to…
I wanted to love this. The branding is great and the quiz was thorough. But after 6 weeks I felt minimal difference and the price point is hard to justify without clearer results. May try again in the future.

not for me unfortunately
gave stack a proper 8 week try. the experience was great — quiz, delivery, packaging all lovely. the product just didn't deliver the energy and sleep improvements i was hoping for. disappointed given the price but i know it works differently for everyone.

Didn't feel any difference
Two months in and honestly couldn't feel much change. Good experience overall but the results just weren't there for me.

DISAPPOINTED honestly
Had such high hopes. The quiz was GREAT and the brand feels premium. But after 7 weeks I genuinely didn't feel much different. Energy maybe slightly better but nothing close to what others describe. Really disappointing at this price point.

Didn't work as well as I hoped
Unfortunately Stack didn't work as well as I'd hoped. The quiz was good and the concept is solid, but after two months I genuinely didn't notice much difference. May just not be the right fit for my body chemistry.

unfortunatly didn't work for me
had high hopes for stack. the quiz was good and the packaging is lovely. just didn't notice much of a differance after nearly 2 months. dissapointing given how much it costs. might not be right for everyone.
