I've been using it for a few years. I started when I decided I really needed to lift to keep my strength up as I get older (I'm closing in really fast on 62). There's always so many variables in working out and life for me to say whether it helped on recovery. I did perceive it helped in the weight room, which I also felt helped in my strength in the pool and on the bike. I did stop taking it 6 months ago (and stopped lifting), I just started lifting again this week, and will be starting the creatine also.
