These answer most messages
Where is my order?
Orders placed before 2pm ET ship the same business day. You get a tracking link by email as soon as the label is scanned — check your spam folder first, then write to us with your order number.
How do I claim the 90-day guarantee?
Email support@marsmeno.com with your order number any time within 90 days of delivery. We refund the purchase and you keep the bottles — there is no return shipping.
Can I change or cancel my subscription?
Yes, from your account at any time — pause, reschedule or cancel. If you cannot get in, write to us and we will do it for you.
Can I take this with my medication?
We cannot give medical advice. Show the supplement facts panel to your physician before starting if you take prescription medication or manage a health condition.
