We built Mainstay for one reason: to be the protein you can actually finish. If it's not right for you, we make it genuinely easy to get your money back — no fighting, no fine print.
Our 60-Day Taste Guarantee
We know the hardest part of any protein is whether you'll actually be able to drink it. So we guarantee that, not just the product.
If you're not happy with Mainstay for any reason within 60 days of delivery, we'll refund you.
To start a refund, just email [support@mainstaydaily.com] with your order number and we'll take care of it. Most requests are approved within [1–2] business days.
How refunds work
- Refunds are issued to your original payment method.
- Once approved, please allow [5–10] business days for the amount to appear, depending on your bank or card provider.
- Original shipping was free, so there's nothing to deduct there.
Returns
For most refund requests under our guarantee, you won't need to return anything — we'd rather you keep or dispose of the bag than pay to ship it back.
If we do ask for a return in a specific case, we'll email you a prepaid label. Please don't send items back to us before contacting us, as we can't process returns received without a request on file.
