Simma simma now. It was just a question.
To answer the question, no i dont think so. It does kinda of sound like it might as IGF attaches to ANYTHING and could possibly make it grow so its not that dumb of a question, BUT IGF makes the body use FAT for energy instead of muscle, which i think is the reason for the lethargy when using it. Also many people have commented on how lean they stay while consuming monstrous amounts of calories.
