I began using Conocb2(clinical strength) a little over a month ago. First of all, I am almost 76 years old, I’ve been a full time personal trainer for 45 years, I was a competitive bodybuilder for 6 years, and I have a myriad of injuries and ongoing daily pain. When I use the dropper measure amount under my tongue, I feel enormous relief within 30 minutes or less. So, now I’ve ordered 6 bottles, so I can share my experience with my clients, one of whom is a doctor, who I gave a dose 30 minutes prior to his workout on 3 occasions, and he, himself, noticed a big difference in the level of shoulder joint pain, that he typically experiences, when he works upper body.This stuff is the real deal!!
