HorseBoost carries a 60-day money-back guarantee from the date of purchase.
The guarantee runs for 60 days from purchase and covers dissatisfaction with your results or your overall experience. The brand requires at least 30 days of use before a refund request becomes eligible, narrowing the practical refund window to roughly days 30–60.
Contact the official store directly at contact@customercs.com or +1 (507) 448-8190 with your order number, within the 60-day window. Some guarantee programmes require unused or empty bottles to be returned; confirm what applies to your order before shipping anything back.
