30-Day Money-Back Guarantee
Built for results. Backed by confidence.
At Gray Labs, we don’t believe in filler formulas—or fine print.
We created our supplements for high performers who expect to feel a difference. That’s why every first-time purchase is backed by our 30-Day Money-Back Guarantee. If Core NAD+, Male+, or Female+ doesn’t meet your expectations, we’ll make it right.
No hoops. No return shipping. No problem.
How It Works
- Contact us within 30 days of receiving your order.
- Email support@graylaboratories.com with your order number and a brief reason for the request.
- We’ll issue a full refund to your original payment method—no need to return the product.
Note: This guarantee applies to first-time purchases of each product. Refunds are limited to one bottle per product type per customer.
Why We Offer This Guarantee
We don’t expect blind trust—we earn it. Our formulas are science-backed, clean, and precision-dosed for people who care about performance, not marketing hype.
But biology is personal. If you don’t feel a noticeable benefit within 30 days, we believe you deserve the confidence of a no-questions-asked refund.
