Returns
Final once shipped
Because these are research materials that can't be restocked once they leave us, orders are generally final once they've shipped.
If something's wrong
If your order arrives damaged, is missing vials, or doesn't arrive at all, email us within 48 hours and we'll make it right — a replacement or a refund.
How to request
Email orders@sterlingresearch.shop with your order number, and — for a damage or quality issue — a quick photo. We'll take it from there.
Payment problems
Paid but your order didn't go through, or were charged the wrong amount? Reach out and we'll sort it out promptly.
