I don't use any fat burners or Pre-workout stuff. My suggestion would be very similiar to some of the other suggestions that have been replied to you. LOL if that makes any sense.
Use Dream Tan, it covers tattoos pretty good, but unless it takes away from your definition, it should no be a problem. All the best man lets rock next year.
2013! will be awesome, I am going to be doing many shows, and get that Pro Win! Vegan style #Plantstrong and hopefully meet some of you at the competitions.
