Alshon,
It’s been reported that you were caught with a banned substance in your system at a random test for Performance Enhancing Drugs:

Be certain if you are taking an enhancing substance of any kind (drug, supplement, other) that you are getting it from a licensed professional that measures its affects and knows the use of the product and its status within the NFL. Nowadays you can even check on the NSF Sport App to see the substances that absolutely are not banned…
Next time you are looking to enhance performance without risking your big contract, check out the improvements in glare, contrast, and visual processing resulting in shortened reaction times and better play realized by Vizual Edge by Eye Promise. NSF certified and sport approved at all levels this product has no negative side effects, is routinely recommended down to age 17, and can enhance performance without changing anything about your physical training.
Combine visual enhancements with sports vision training and you could really elevate your game.
-Dr. Mark W. Burke
P.S.
The MPS II tests the density of the pigment in the macula (center of vision) in your eye so you can track your improvement and know the product is reaching the target tissue! Combine this with contrast and glare testing at an MVP (Maximum Vision Performance) test at 4Sight iCare and you’ll know that the product is working. There’s no test to check if a PED is actually making you better, only one to make you sit out 4 games and lose $3.5M.
