Many companies approached Phil before he turned pro and after he won his two pro shows. Phil is very happy with MetRx and yes, he uses their products. Look for their new ads featuring Phil in the mags now.
I hope Muscle Tech finds a way to use Melvin in a more creative and effective way then just inserting his image in the same ads they've been doing with Cormier, Henry, Cutler, Charles, Dillett, etc.
