How long should a supplement guarantee be?

Minimum 60 days — matching the evidence-based evaluation period for most supplements. Testosil® offers a lifetime guarantee, the most generous in the category.

Can I actually get a refund if supplements don't work?

Yes — with established brands and purchases through official websites. Contact the manufacturer directly within the guarantee window with proof of purchase.

Does the guarantee cover open bottles?

For Testosil® (lifetime) and most Leading Edge Health products — yes. Most legitimate guarantees allow return of opened containers.

What happens if I buy from Amazon?

Guarantees are only valid on purchases from official manufacturer websites. Amazon purchases are generally not covered by manufacturer guarantees.

Are Supplement Money-Back Guarantees Real? Complete Guide

Q: Are supplement money-back guarantees real?

Yes — for established brands like Leading Edge Health (Testosil®, VigRX Plus®). These companies have brand reputations to protect. Guarantees from unknown brands or Amazon sellers are significantly less reliable.

⚡ Quick AnswerLast Reviewed: July 2026

Legitimate supplement money-back guarantees are real and honoured by established brands. Key indicators of a genuine guarantee: clear terms on the official website, the window covers the full evidence-based evaluation period (60+ days), the manufacturer has a track record, purchase must be made via official website only. WellnessChecked only reviews products with genuine guarantees.

What Makes a Guarantee Legitimate

60+ day window: Short (14-30 day) guarantees are insufficient to evaluate a supplement properly. 60-67 days covers the evidence-based evaluation period
Clear terms on official website: Terms, conditions and refund process clearly stated — not buried in fine print
Established manufacturer: Leading Edge Health (Testosil®, VigRX Plus®, GenF20 Plus®) has been operating for 20+ years. Track record matters
Official site purchase only: All legitimate guarantees require purchase through the official manufacturer website — not Amazon or other marketplaces
No requirement to have results: Legitimate guarantees cover dissatisfaction for any reason, not just lack of results
