My last box was severely damaged
My last box was severely damaged. I contacted them through their websites never got any reply. It says on their website, easy cancellation. I spent an hour on their website looking cannot find any way to cancel so at this point, they are stealing money from me.

Hello Rick! We reached out to you 20 days ago and sent a replacement box. I just checked the tracking, and it says it was delivered to the front desk Sept 5th. Please check your spam emails if you did not see the email from us.

Hi Luke! Your package is in transit and on its way to you! You should have received tracking via email if you missed it email us at info@thegainzbox.com to provide that number for you.
No worries
No worries, I’m still a fan of Gainz. But I am a bit disappointed. I didn’t see the value in this box. I go to the gym regularly and I’m in CrossFit so I already have plenty of jump ropes. I might not ever open that package and the muscle roller is a little bit small for me. It seems to be more fit for a lady so I feel like I paid for what little protein packs and supplements were in the box. The shirt is too thick for me because I live in Florida. I’m really hoping for a heavy jump rope maybe one of the weight bags or a new gym bag that would be some gear that I could utilize but all in all still a great mystery box. Looking forward to next quarter.

Thank you for the honest feedback and for continuing to support GainzBox! I completely understand where you’re coming from.
We really appreciate the suggestions, and heavier jump ropes, weight bags, gym bags, and other usable gym gear will be strongly considered as we plan upcoming boxes.
Thanks again for sticking with us!
reliably accurate
reliably accurate. They say what they are sending, and they send it quickly and everything is in proper shape. Never had an issue with Gainz box. Always fun to open the box and reveal the goodies inside.

Minimal items in box
Minimal items in box. Box is maybe beneficial to those new to body building, but not for experienced. Small women’s shirt is a men’s small. Sampler box with not many items to sample
