Get a bottle of each; Fertility for Women and Fertility for Men.
Large doses are not necessary to achieve results. The highly successful Fertility for Women was created to aid conception, and was immediately found to be an extreme libido enhancer as well. So much so, that the Fertility for Men has been requested by my customers for years, to accompany it.
Warning: potential side effects include reawakened romance, and pregnancy. Please use responsibly.
