My knees no long hurt. My achilles inflammation disappeared. Mountain Red’s products allowed me to train, whereas before taking deer velvet, I was continually breaking down and visiting my friendly physio. My breathing control and recovery were unbelievable. It reminded me of the way altitude training gave me a significant edge during intense swim training sprints and hill repeats on the bike. The other impressive change I noticed was the recovery from hard training sessions and lack of muscle soreness, given my limited training build up.
