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…
good product, nice packaging, the quiz was solid. been taking it for 5 weeks and definitely feeling more energy during the day. would give 5 stars if there was an app to go with it but that's a minor thing. overall recommend.

Good product with room to grow
I've been using Stack for about two months now and my overall experience has been positive. The quiz was genuinely thorough — more so than I expected — and the personalized pack that arrived clearly reflected my answers.
Results have been good. My energy throughout the day is more stable, I'm sleeping better, and my workout recovery has improved. These are real, noticeable changes and I'm happy about them.
The reason I'm giving 4 rather than 5 stars comes down to a few things I'd love to see added:
1. An app or dashboard to log how I'm feeling over time and track progress
2. The ability to re-take the quiz as my lifestyle changes (I changed jobs since signing up)
3. More in-depth explanation of each ingredient in my pack and why it was chosen for me
The core product is excellent and I'll keep subscribing. These are improvements I hope the team considers.

Strong results, just one small thing
Very happy with Stack overall. The packaging is clean, delivery was quick and the quiz was thorough. I just wish the website had a bit more education around each ingredient and why it was included in my pack. Results have been good though — energy and sleep both improved.

GOOD product, minor things to fix
Overall really happy with Stack. The quiz was GREAT and I've noticed real improvements in my energy and sleep. Only thing stopping me from 5 stars is I'd love an app to go alongside it. But the product itself is SOLID. Recommend.

Enjoying it so far
Enjoying Stack so far. I'm about 7 weeks in and energy has improved, sleep is more consistent. The personalization feels real and not just marketing. Minor thing — the quiz could ask a few more questions about dietary restrictions.

Great concept, good execution
Happy with my Stack experience. The quiz was detailed, the packs arrived quickly and I've felt improvements in sleep and energy. My one suggestion would be a mobile app to go alongside the subscription. Otherwise great.

solid, minor improvments needed
great product overall, the personalization definately works. i've noticed better sleep and more stable energy after about a month. only thing is i wish the website explained a bit more about each ingrediant in my pack. but the results have been good so i'll keep going.
