We read 491 ClickBank supplement refund policies. Here's what "guarantee" actually means.
Every product in our review catalog states a refund or money-back window somewhere in its sales copy — usually buried past the order button. We pulled the stated window, price, category, and rebill status for all 491 offers and counted what's actually there, not what the ad implies.
Stated refund window, across 480 disclosed offers
Nearly every offer that discloses a window lands on exactly one number. The rare exceptions cluster at 180 and 365 days — read the outliers below before assuming "longer guarantee" means "better deal."
The finding: a longer guarantee is a rebill signal, not a generosity signal
Across the 455 offers with the standard 60-day window, 26.8% also charge a recurring fee behind the initial purchase. Among the 25 offers that stretch the guarantee past 60 days — to 90, 180, or 365 — that rebill rate almost doubles to 48.0%. The pattern holds by price band too: the cheapest offers (under $40) never carry anything but the 60-day floor; it's only once price crosses $40 that a longer window shows up, and it shows up alongside a subscription more often than not.
| Price band | Offers | % with a >60-day window |
|---|---|---|
| < $20 | 32 | 0.0% |
| $20–39 | 83 | 0.0% |
| $40–59 | 45 | 4.4% |
| $60–99 | 91 | 7.7% |
| $100+ | 193 | 8.3% |

Methodology
Sample: all 491 ClickBank supplement and health offers in the Supplement Skeptic review catalog as of 2026-08-24 — every product we have published a review for, not a curated subset.
What was counted: a stated refund/money-back/guarantee
window in days. We first checked each product's structured refundDays field; because that field defaults to 60 in our
content schema and is rarely overridden, it cannot distinguish a real
disclosure from an unset default. So instead we searched the full
published review body — including the vendor's own sales-page language
we quote when sourcing a review — for an explicit phrase of the form
"N-day money-back," "N-day refund," or "N-day guarantee," matched against
the windows ClickBank actually supports (14, 30, 60, 90, 180, 365 days).
11 of 491 products (2.2%)
have no such phrase anywhere in the review and are marked "not stated" —
we did not guess a number for them.
Conflicting mentions: a small number of reviews mention
more than one day-count (for example, discussing both the ClickBank
platform standard and a vendor's marketing claim). In those cases we
took the longer of the two, since that is the number the offer is
advertised on. Those rows are flagged refundWindowSource:
"body-multi" in the CSV so you can audit them yourself.
Recurring billing: comes from each product's structured hasRecurring field, set by hand during the original review
from the vendor's own checkout/terms page — not inferred from the refund
text.
What this is not: a claim about legality or intent. A 60-day window is ClickBank's own vendor requirement, not evidence a product is a scam. The finding here is narrower and, we think, more useful: the length of a guarantee tells you close to nothing about the product, and a guarantee longer than the platform floor correlates with a subscription you have to actively cancel.
