As an artist i can tell you that there will be no problem with getting the tattoo as long as your artitist is legit and knows what they are doing. (Only problem would be from poor technique on the artists part) Ink is only set into the top (papillary layer) of the dermis for best healing and long term results so it will have no affect on your cycle. Only thing I will ask you is how serious are you about your training and cycle??? Think about the down time you are going to go through while it heals. You don't want to be in the gym with a fresh tattoo and allowing any kind of bacteria from eqipment to get into it causing an infection. Why not take your cycle seriously and train hard, eat everything, get proper rest, and eat some more. Worry about the ink later man.....
