Agreed. While B12 injects are a god send to women - makes them feel healthier, less bruising, etc, the appetite increase will be hell on a diet.

This is her first contest and she lives in VEGAS...one of teh female IFBB pros is helping her...I asked her to ask her trainer, she said that she had no idea...anyways...
