A 60-day money-back guarantee sounds generous, but the conditions decide what it is worth. This checklist uses the FDA consumer page, credited below, and applies it to a real brand. It is general information, not medical advice.
1. Find out whether opened products can be returned
Many guarantees require the seal to be intact. For a supplement you need weeks to judge, an unopened-only rule means you can only get a refund if you never try it. Look for the phrase “protective seal intact” or “unused” in the policy.
2. Check the approval process
Some policies require written approval before you send anything back, and refuse returns sent without it. Note the returns address and the deadline.
3. Look at exchanges and bundles
If exchanges are not offered, a wrong choice means returning and reordering. A guarantee is worth more on a single pack than on a six-month bundle you cannot return once opened.
4. Read the claims as claims
The FDA consumer page on dietary supplements says that under the 1994 law the FDA is not authorized to approve dietary supplements for safety and effectiveness before they are marketed. A guarantee is not evidence that a product works.
5. Talk to a professional if you have a reason to
The same page advises talking to a doctor, pharmacist or other healthcare professional before deciding to use a supplement, particularly if you take medicines or have a condition.
An example: checking a brand against the list
In our Forge Men review we applied these questions. The brand offers 60 days, or 180 for a 6-month supply, but requires an intact protective seal, offers no exchanges and makes claims we could not verify.
