1. While Red Growth doesn't have any ingredients in it that specifically increase your appetite, we've got a lot of feedback from guys saying that it does increase their appetite. This is probably due to the fact that your muscle are working harder and using more energy on Red Growth which tells your body to eat more and get more nutrients to fuel them.
2. Good question. Red Growth specifically works on the androgen receptors in your muscles & bones, thereby helping increase your strength and overall muscle growth. We don't believe that Red Growth would have any impact on your tendons & ligaments alone. However, by increasing your training frequency and overall strength, your tendons & ligaments will get stronger as your muscles get stronger. So it's a secondary effect.
As you get older, it's important to maintain flexibility in your joints. We recommend that you also incorporate a daily stretching routine into your training program to help your tendons & ligaments adjust to the increased workload that Red Growth will help you do.
