QDoes INFINIT have a shelf life?

A Yes, our products are good for 2 years from the date of manufacture. 

If you have a Preset Formula (GO FAR, SPEED, HYDRATE, etc.), you can find a "Sell By" date on the back near the barcode — It will start with "SB..." followed by it's Sell By date — It is good for 1 year from the Sell By date. 

If you have a Custom Formula, you will find the manufacture date on the front, and it will be good for 2 years from that date.
