Hey Joe! I was using Muscle up (amino acids) and noticed while they did recover faster the Niacin in the Muscle up actually made them look alot leaner. Along with the Muscle Up after a long hunt I spend about 15 minutes when we get home massaging my dog down
. Crazy, I am not sure but it has allowed me to bond more with each of them and also has got my dogs back in the forest alot sooner then I would have before.
