Has anyone tried this before? A buddy of mine was doing guest posing at a comp a while back and told me about taking insulin the morning of the contest. He said that is what most of the pros do. They usually take about 30ius and then take in a bunch of pie filling or anything loaded with sugar. Keeps them incredibly full as well as hard and vascular. I am thinking of experimenting with this on my next contest. Probaly more around 10-15 ius for me. Far from the pro size.
