The guaranteeThe Memodyne 60-Day Guarantee, Counted From Purchase
Memodyne carries a 60-day money-back window counted from the date of purchase, unless the supplier’s own sales page prints a longer one. Claims are made on the order line with the order ID, the bottles go back to a New York address, and return postage is the buyer’s cost. It is a promise about money, not about outcomes.
This page sets out how the window is counted, what it covers, what it does not, and the exact sequence of a claim.
How the Memodyne window is counted
Two possible start dates, and why the shorter one is the honest one to print.
From the date of purchase. That matters because there are two dates a window could be counted from, and they are not the same length.
| Counted from | What it means | Which is safer to plan against |
|---|---|---|
The date of purchase | The clock starts the moment you pay, before the parcel is packed | This one. It closes first, so planning against it can never leave you late |
The date of delivery | The clock would start days later | Longer, and not what is stated here |
Purchase precedes dispatch, so a window measured from purchase is the shorter and more conservative of the two. That is the one this desk prints and the one to hold in your head.
- Day 0. The date on your order email. Everything counts from here.
- Day 30. The end of the first bottle, which is roughly the wait the distributor states before judging anything. The seller’s own page words its guarantee around at least 30 days of use.
- Day 45. The last comfortable day to decide and still post the bottles back inside 60 days.
How a Memodyne claim is made, step by step
Four steps, one telephone number and one address.
Call the order desk
+1 (302) 200-3480, with the order ID from your confirmation email in front of you. You can also write to [email protected].
Send the bottles back
To 1740 Broadway, Floor 15, New York, NY 10019, USA. Write your full name, your email and the order ID on a sheet inside the parcel, and pay for tracking. Return carriage falls to the buyer, and a parcel nobody can trace is the single situation this process has no answer for.
Wait for the credit to be processed
Three to five business days after the return is received, on the desk's own stated timings.
Wait for the card
Then five to ten days for the refund to appear, which is the card network's timing rather than the desk's.
The refund policy carries the same sequence in policy language, and the two are deliberately identical: a guarantee page that promises more than the policy delivers would be the worst kind of page on a site like this.
What the Memodyne guarantee does not cover
Five limits, stated plainly rather than buried.
- It does not cover return postage, which is the buyer's cost in every case.
- It does not promise an outcome. A money-back window is a commercial term and says nothing about what the capsule will do.
- It does not extend itself because a parcel was slow, because it is counted from purchase rather than from delivery.
- It does not apply to a bottle bought through a marketplace listing, which this desk cannot see and cannot refund.
- It does not replace the order email. Without an order ID a claim cannot be matched, and the desk has no other way to find you.
A 60-day window is longer than most, and that is worth something to a first-time buyer of an unfamiliar formula. It is also a commercial decision by a seller, not evidence about a product, and it should not be read as one. What the evidence says is on how it works.
How to spend the 60 Memodyne days well
Four stages, ending two weeks before the window closes rather than on the day.
A window is only worth what you do inside it. Sixty days is enough to run a fair test of a daily capsule, and it is also enough to lose track of entirely if nothing is written down.
Week 0: write down what you are watching
Two or three specific things rather than a general sense of sharpness: finding a word, following a long article, the last hour of a working afternoon. Vague expectations get confirmed by whatever you already believed.
Weeks 1 to 4: keep the rest of the month ordinary
Changing three habits at once makes the answer unreadable. A 2026 network meta-analysis found aerobic exercise improved executive function in healthy older adults, so starting to run in week two will give you a result you cannot attribute.
Week 4: read what you wrote
The distributor states a typical wait of 3 to 4 weeks, so this is the first fair moment. The results timeline sets out what other buyers reported at this point.
Day 45: decide
Either carry on or call the desk. Fifteen days is comfortable for a tracked parcel to reach New York, and it keeps the claim inside the window without any anxiety about the post.
What the Memodyne window is worth against the category
Four honest readings of a long money-back window.
Sixty days from purchase is at the generous end of what supplement sellers offer, and it is worth understanding why a seller would give it.
A slow product needs a long window
The distributor states a wait of 3 to 4 weeks. A 30-day window would close at roughly the moment a buyer was first in a position to judge, which would be either unfair or ineffective. Sixty days is the shortest window that makes sense for this product.
It shifts the risk, and the seller knows the odds
Most buyers who are going to keep taking a capsule have decided long before day 60, and most who stop never claim. A long window is a real benefit to the buyer who uses it and a small cost to the seller on average.
It is not evidence
A window says what a seller is willing to risk commercially. It says nothing about the formula, and reading it as confidence in the product is a mistake this desk would rather you did not make.
Use it anyway
The window is one of the few terms here with a number this desk can guarantee. The panel shows the capsule’s amounts sit well below the research, so the window is the strongest thing in the offer.
Order Memodyne with 60 days to decide
The window runs from the day you pay. One bottle is a month, the distributor states a wait of 3 to 4 weeks, and day 45 is the last comfortable moment to change your mind.
