The promise01
What is the ZenCortex 60-day money-back guarantee?
The ZenCortex guarantee is a 100% money-back promise that runs for 60 days from the original purchase, as the seller states it (ZenCortex info page).
The wording says you can return the product, even empty bottles, within the 60 days. It does not ask you to prove that the drops failed. It is a seller policy, not a certification, and it applies to the seller named at checkout.
The info page says the refund comes within 48 hours of the return arriving, minus shipping and handling fees. The seller's brief gives a different timeline. Both are covered below, with the steps in the ZenCortex refund policy.

Where it comes from
A guarantee like this lives in the seller's terms. We are a retailer of ZenCortex that earns money from order links, so we do not issue refunds ourselves. The order desk does.
The steps02
How do you claim the ZenCortex guarantee?
Claim the ZenCortex guarantee by calling +1 (380) 868-3839 with your order ID, then mailing the bottles back with tracking.
Call before you ship. The desk confirms where to send, and it can tell you which refund timeline applies. Include your full name, email and order ID in the parcel.
- Day 0
Order and keep the order email
Your order ID is what the order desk uses. The 60 days count from the date you paid.
- Within 60 days
Call the order desk with your order ID
Call +1 (380) 868-3839 for return instructions. The info page says to return the product, even empty bottles, anytime within 60 days of purchase.
- Then
Mail the bottles back with tracking
The brief says the buyer pays return shipping. Include your full name, email and order ID, send it to the address the desk gives you and keep the tracking receipt.
- After the return arrives
Refund to the original payment method
The info page says a full refund within 48 hours of the return arriving, minus shipping and handling fees. The brief says 3 to 5 business days after the return is credited, then 5 to 10 days on the card. Ask the desk which applies.
Keep the tracking number until the refund shows on your card statement.
Costs03
Who pays return shipping on the ZenCortex guarantee?
The buyer pays return shipping on the ZenCortex guarantee. The seller does not send a prepaid label.
That is the largest cost of a claim. The info page also takes shipping and handling fees out of the refund. On the 2-bottle pack, whose shipping amount is not printed, that could mean part of the original fee does not come back.
Weigh the parcel before you ship. A heavier return costs more, and six bottles of 60 mL glass is a bulky parcel. Use a tracked service, keep the receipt and photograph the parcel before you close it.
Because the guarantee covers empty bottles, you do not need a full bottle left. You do need to ship them back, though, so do not throw anything out until the refund lands.
Timing04
How fast is a ZenCortex refund?
The sources differ on how fast a ZenCortex refund arrives, so we cannot give one number.
The info page says within 48 hours of the return arriving, minus shipping and handling fees. The brief says the refund goes out once the returned bottles are received and credited, in 3 to 5 business days, and may take 5 to 10 more days to show on the card statement.
| Source | When the refund is issued | Fees |
|---|---|---|
| Seller's info page | Within 48 hours of the return arriving | Minus shipping and handling |
| Seller's brief | 3 to 5 business days after the return is credited, then 5 to 10 days on the card | Not stated |
Ask the desk which one applies, and write down the answer with the date.

What should you confirm before you use the ZenCortex guarantee?
Before you use the ZenCortex guarantee, confirm the return address, the refund timeline, the fee deductions and the exact date your 60 days end.
- Count 60 days from the purchase date, not the delivery date, unless the desk says otherwise.
- Ask whether opened and empty bottles are accepted. The info page says they are.
- Confirm the returns address. The brief prints 2 Hudson Place, Suite 400, Hoboken, NY 07030, with the state as NY, though Hoboken is in New Jersey.
- Ask whether shipping and handling fees will be deducted, and how much.
We could not find an independent review of how the guarantee works in practice, and we show none. The FTC says claims in ads must be backed up, and a guarantee is only as good as the seller's follow-through (FTC, Health Products Compliance Guidance).
Using it well06
When should you use the ZenCortex guarantee?
Use the ZenCortex guarantee as soon as you decide the drops are not for you, and well before day 60 ends.
Waiting is the usual mistake. Mail takes time, and the claim must start within the window. A bottle lasts 30 days at two droppers a day, so a 2-bottle pack runs out around day 60. Decide at about day 30 to 45 if you want leeway.
Stop taking ZenCortex and call a doctor if you get side effects. Do not stop or change any prescribed medicine. A hearing change, ringing in one ear or dizziness needs a clinician, and sudden hearing loss in one ear is an emergency (NIDCD, Sudden Deafness). A refund will not fix those.
If you are buying because hearing seems to be slipping, book a test with an audiologist or doctor (NIDCD, Who Can I Turn to for Help with Hearing Loss). A supplement is not a replacement for that.
Our view07
Is the ZenCortex guarantee a good one?
The ZenCortex guarantee is a fair safety net, but it is not risk-free, because you pay return shipping and the refund timing is unclear.
In its favor
- 60 days is a long window for a 30-day bottle
- Empty bottles are accepted
- A phone number is given for claims
Against it
- Buyer pays return shipping
- Two different refund timelines
- Fees may be deducted

FAQ08
ZenCortex questions people ask
Can you get a ZenCortex refund after the bottles are empty?
Yes, according to the seller's info page, which says to return the product, even empty bottles, within 60 days. You still pay return shipping. Call the order desk first so they can confirm the address and the refund timeline.
Does the ZenCortex guarantee have conditions?
The conditions we found are the 60-day window, returning the product, calling with your order ID and mailing the bottles with tracking. Beyond that, the seller's terms may add more, so ask the order desk before you ship.
What is the phone number for a ZenCortex guarantee claim?
Call the ZenCortex order desk at +1 (380) 868-3839 with your order ID. Do not use this website's contact address for claims, since it cannot see orders. The sales email is [email protected].
Does the guarantee refund the cost of ZenCortex e-books?
The e-books are free with the 3 and 6 bottle packs, so there is nothing separate to refund. Whether they must be returned is not stated, so ask the desk. The refund is the pack price, minus fees.
What happens if the seller does not answer a ZenCortex claim?
Keep your tracking, your order ID and notes of every call. If the refund does not arrive, you can ask your card issuer about a dispute.
Is the ZenCortex guarantee the same as a satisfaction guarantee?
It is described as money-back, and the sources do not ask for proof that the drops did not work. Whether the seller questions your reason is not stated. Ask the desk what it needs to hear on the call.
Does the ZenCortex guarantee apply to bottles bought elsewhere?
We could not confirm that. The guarantee is stated by the seller whose checkout this site uses. A bottle from a marketplace or reseller may not qualify, so check with the seller before you rely on it.
