Lactigo is a topically applied transdermal water-based analgesic gel. It's principle and primary ingredients are water, L-Carnosine and Magnesium Sulphate (Remaining ingredients listed below). The most important concept to mention is that Lactigo has a patented "one-of-a-kind" delivery system where the water molecules carry the Carnosine and Magnesium down through the dermis and deep into the muscle tissues. It has a 100% absorption rate because of this patented delivery system. Lactigo will work in as little as 30 minutes or less from the application. Lactigo holds 51 patents and with 7 more pending on this delivery system. There is literally no other product that can replicate this delivery system currently. So in other words, Lactigo is a one-of-a-kind product and it works very successfully! Just ask the many professional athletes that use it continuously.
