Virilaxyn RX The decision to take supplements is up to you. If you are immensely involved in a sport you may be tempted to go it alone. DON'T DO IT! One of the reasons for this is that you may already produce enough of the muscle equipment and not need these supplements. For another, you need to know which things you need to supplement if you want to be healthy and successful. Only take what you need, who knows you may not need them at all.
