Short answer: If, after at least 30 days of use, you are not completely satisfied with your results, contact customer support to arrange a return — a specific, conditional guarantee requirement.
Why a minimum usage period is required, not just a purchase-date window
The guarantee clock starts at purchase, not delivery — a minimum 30-day usage period is required before a claim is eligible, a direct, specific structure worth understanding before ordering.
Why this connects to the formula's own honest timeline expectations
Daily amino acid and B-vitamin supplements generally require four to eight weeks of consistent use before any subjective effects become noticeable — this 30-day minimum sits near the early end of that range.
💡 Worth knowing: the guarantee window is 60 days total, but claims are only eligible after this 30-day minimum has passed.
