Max Size Cream is a male enhancement topical formula in a tube that offers a unique transdermal delivery system for quick absorption and immediate results. It is the only topical male enhancement product containing Butea Superba, a well-documented and patented natural PDE-5 inhibitor that helps effectively 'lock-in' the enzyme responsible for enhancing erectile response. This natural herb is just now becoming available in the U.S. after years of research in Thailand.
