GuaranteeThe Slim Metrix 60-Day Money-Back Guarantee
Slim Metrix carries a 60-day money-back guarantee running from the date of purchase, opened bottles included. It is longer than the smallest pack lasts, which is the point of it: sixty days of capsules and a sixty-day window mean a fair trial and a refund are not a choice between two things.
What it covers, how to use it, and the three places a refund usually stalls.
What the Slim Metrix guarantee actually covers
Six answers, in the order people ask them.
| The answer | |
|---|---|
| Length | 60 days from the date of purchase, not from the date of delivery and not from the first capsule. |
| Opened bottles | Included. A guarantee that required an unopened bottle would not be a trial period. |
| Who pays return postage | The buyer. Use tracking and keep the number until the money lands. |
| How long the money takes | Three to five business days for the desk to process, then five to ten more on the card. |
| How it starts | A phone call to +1 (562) 523-2626 with the order ID. |
| What it is not | A medical promise. It is a purchase policy and nothing more. |
The seller's own page carries the governing wording and a longer window there would override this one.
The single most useful thing about a 60-day window on this particular product is the arithmetic. The typical wait reported by buyers here is 4–8 weeks. Two bottles is sixty days. The window is sixty days. Those three numbers line up, which is unusual and is worth using.
Why a 60-day window suits Slim Metrix in particular
Three reasons, and none of them is that sixty sounds better than thirty.
Most guarantees in this category run thirty days, and on this product thirty days would be close to useless. Three reasons, and they are all about the timeline rather than about generosity.
The first is what buyers say. 4–8 weeks is the commonest wait in this desk's own review file before anybody decided, and the commonest complaint is about the fortnight before that. A thirty-day window would expire while most people were still in the part they describe as nothing.
The second is what the research measured. a 2025 insulin-sensitivity meta-analysis required six studies, 673 participants, at least four weeks of supplementation each as an inclusion criterion. a 2019 meta-analysis in Clinical Obesity found improvements concentrated in trials of 12 weeks or less at doses up to 400 mcg a day. Mousavi's dose-response meta-analysis found 28 trials; weight fell 0.51 kg, and the effect sat in trials under 500 mg a day running three months or longer. Nothing cited on this website measured anything inside a month.
The third is the pack ladder. The smallest rung is two bottles, which is sixty capsules and sixty days. A thirty-day window on a sixty-day pack would mean asking somebody to decide with half the product unopened.
The window, the smallest pack and the typical wait are all sixty days, so the guarantee is exactly long enough to run the test properly and no longer.
The Slim Metrix window against what the category usually offers
Four lengths this category sells, and what each one is actually long enough to test.
| Window | How common | What it is long enough for |
|---|---|---|
| 14 days | Occasional, usually on a trial offer | Establishing that you can swallow the capsule. Nothing else. |
| 30 days | The most common length in this category | One bottle. On a product whose typical wait is four to eight weeks, that expires during the part buyers describe as nothing. |
| 60 days | Less common, and what this product carries | Two bottles, eight weeks, and a decision made with notes rather than an impression. |
| 90 days or more | Rare outside subscription models | Three bottles. Longer than the wait, and usually attached to terms worth reading closely. |
Lengths in the first column describe the category rather than any named competitor. The third row is the one this product sits on.
A window is the easiest term in this business to compare, which is exactly why it is worth comparing. Thirty days is the default and sixty is a meaningful step above it on a product with this timeline.
It is also the one number on this whole website that needs no qualification. The ingredient amounts come with a provenance note, the review figures come with a caveat about what summary copy is, and the prices come with the date they were read. The 60 days is simply 60 days.
How to claim the Slim Metrix guarantee
Five steps, and the whole thing starts with a phone call rather than an email.
Call the order desk with your order ID
The number is on the order email and in the footer here. The website address cannot see orders, so it cannot start a refund.
Ask for the return address before you post anything
An unannounced parcel can be refused, and a refused parcel is a refund that stalls for a fortnight.
Put your full name, email and order ID inside the box
A box with no name in it is the commonest reason a refund waits.
Post it with tracking, at your own cost
Return postage is the buyer’s. Keep the tracking number until the money lands.
Expect 3–5 business days to process, then 5–10 on the card
Two separate waits, and the second one belongs to your bank rather than the desk.
A parcel posted before the return address was issued, a box with no name or order ID inside it, and a return sent to the office address rather than the returns address. All three are avoidable and all three are the same phone call away from being avoided.
Using the Slim Metrix window as a trial rather than as a backstop
Five steps that turn a refund policy into a test.
A guarantee is usually treated as insurance against a bad purchase. On this product it is more useful treated as a schedule.
Sixty days is two bottles, which is the smallest pack. It is also longer than the 4–8 weeks most buyers here describe waiting before deciding. So the window is not a safety net attached to the end of a trial; it is exactly as long as the trial should be.
- Order the two-bottle pack and write the purchase date down on the day it arrives.
- Take one capsule each morning with food, changing nothing else for eight weeks.
- Keep the four short notes the results timeline suggests.
- At week eight, read the notes back and decide. The window has a few days left at that point, which is deliberate.
- If the answer is no, call the order desk before the sixtieth day rather than on it.
That plan uses every part of what this desk offers and costs the price of return postage if the answer is no. It is also the only honest way to find out whether a blend like this one does anything for you, because the amounts cannot tell you in advance.
What the Slim Metrix guarantee is not
Four limits, printed so the policy is not mistaken for something larger.
Four things, and the fourth is the one that matters.
- It is not a promise that the product will work. A refund policy is a commercial term and it says nothing about a formula.
- It is not a free trial. Return postage is the buyer's and the bottles come back.
- It is not open-ended. Sixty days from purchase, and a call on day sixty-one is a call outside the window.
- It is not a medical guarantee of any kind. Nothing about this policy relates to health, an outcome or a diagnosis, and reading it that way would be reading it wrong.
Stated the other way round, a money-back window is the one part of a supplement purchase that is fully verifiable before you buy. The formula has two printed amounts and eight rows sharing a total. The policy has a length, a procedure and a phone number, and all three are on this page.
