Shipping and returns
Tracked US shipping, a 60-day first-order guarantee, and a person on the other end of every email. Last updated: October 28, 2026.
Shipping
Rates
Free US shipping when your one-time items total $50 or more, and on every subscription delivery. Orders below that ship for a flat $4.95.
Processing and delivery
Orders are usually prepared and shipped within 2 to 5 business days (Monday to Friday, excluding US holidays). Delivery by USPS then typically takes 1 to 4 business days, depending on your address, so most orders arrive within 3 to 9 business days of ordering. These are estimates, not guarantees.
Tracking
You get a tracking link by email as soon as your order ships. Allow 24 to 48 hours for it to start updating.
Lost or late parcels
If tracking has not moved for 7 business days, email support@cellovi.com within 21 days of the estimated delivery date. We trace it with the carrier, and if your parcel is lost in transit, we send you a free replacement, which usually ships within about 5 business days.
If tracking shows your parcel as delivered but you cannot find it, check with neighbors and your mailroom and allow 2 business days, as carriers sometimes scan early. If it still has not turned up, email us and we will open a claim with the carrier for you. Parcels the carrier confirms as delivered are not covered by our free replacement.
We also cannot replace parcels sent to an incorrect or incomplete address entered at checkout, or parcels returned to us because they were refused or not collected. Email us and we will help you sort it out.
Where we ship
We ship to addresses in the United States only.
Adult-only products
Creatine Monohydrate, its 100-day supply and the protocols that include creatine (Her Healthspan, His Healthspan and Sharp Mind) are for adults 18 and over. New York law requires deliveries of these products in New York to be signed for by an adult 18 or older showing government-issued photo ID. If we cannot ship your order that way, we cancel it and refund it in full before it ships.
Our 60-day first-order guarantee
Try it for 60 days. If your first order with Cellovi is not for you, we will refund the product price, opened or not. You do not need to send anything back.
How to use it
Email support@cellovi.com within 60 days of delivery with your order number and, if you are happy to share it, what did not work for you. A person reviews every request and replies within 24 to 48 hours, Monday to Friday. Once we approve it, we refund the product price to your original payment method within 5 to 10 business days.
What it covers
- Your first order with Cellovi, once per customer.
- One unit of each product in that order. A protocol, The Cell Duo or a multi-month pack counts as one unit.
- The first delivery of a subscription, when it is part of your first order.
- The amount you paid for those products, after any discount.
What it does not cover
- Later orders, including subscription renewals after the first delivery. You can skip, pause or cancel any renewal online before it is charged, and a renewal that has been charged but not yet shipped is cancelled and refunded if you email us.
- Extra units of the same product in your first order.
- Orders placed for resale.
- More than one guarantee request from the same person, household, address or payment method.
- An order with an open payment dispute or chargeback.
- Shipping charges, unless the item arrived damaged, defective or wrong.
Fair use
Refunds under this guarantee are not automatic. We may decline a request, or limit future orders, when it shows signs of misuse, such as several accounts, orders larger than personal use or repeated requests. If we decline a request, we will tell you why.
When these terms apply
These terms apply to orders placed from October 28, 2026. Earlier orders keep the terms that applied when they were placed.
Damaged, defective or wrong items
If anything arrives damaged, defective or not what you ordered, email support@cellovi.com within 21 days of delivery with your order number and a photo. We will send a replacement or refund it, including shipping, at no cost to you.
Returns
Because supplements are taken by mouth, we cannot resell anything that comes back, so we do not ask you to return products covered by the guarantee. Please do not ship items to us without writing first; we will tell you what to do.
Subscriptions
Subscriptions renew every month at the subscribed price until you cancel, and we email you before each renewal. Skip, change the date, pause or cancel online from your account any time before your next renewal date. There is no minimum and no fee.
If a renewal has been charged but not yet shipped, email support@cellovi.com and we will cancel it and refund it in full. A renewal that has already shipped is not refundable unless it arrived damaged, defective or wrong. If a subscription price ever changes, we email you at least 7 days before it applies, and you can cancel before then.
