Deer Antler powder or extract is a very common Chinese herbal medicine category, which has been around for about 5000 years.
I know Ray Lewis has not lead an exemplary life, but are people really going to go after for something as petty as “dear antler?”
Why is it banned?
If he used a BANNED substance, YES!
Lots of banned substances have been used for thousands of years and can be otained from natural sources. That doesn't make them any less of a rules violation. Bodybuilders have used deer antler extract for years to heal minor injuries and increase recovery time so they can work out more often without overtraining. Banned is banned and Ray knows that.
