Preparing for Houston...What is best for making muscles pop and tighten

With show less than one week away, I trying to find something to give my hog to make his muscles tighten and pop. I am considering jello powder...is there a specific brand or flavor that works best? Also thinking about Power Fuel. He is eating 3lbs of 20% (Moorman's) 1/4 of paylean and 1/4 in motion. Please let me know of any helpful hints. I have used Moor Power before and was pleased!

Thanks!

But to me he just aint getting wide enough like the other boars i've seen from his age. his a Pi R Squared X Cant Touch This he will be a year in july ..i feed him a large coffee can of 16% and a large cofee can of cubes...or i'am i not feeding him enough or should i give him some supplements to blow him..
