HoneyFil carries a 60-day money-back guarantee from the date of purchase.
The manufacturer states most men see their best results after 90 to 180 days of consistent use. That is meaningfully longer than the 60-day guarantee window, especially on the 2-bottle package. If you're buying a smaller package specifically to try before committing, do that math before you order, not after.
Contact the official store directly 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.
