For a moment, Steve was uncertain. Perhaps there was still something wrong that he'd overlooked in testing? Was a jock really what he wanted to be?
But he banished doubt from his mind. This would work; he wanted it to work. He stuck the syringe into his arm.
When he pulled it out, the pricking pain subsided. But at first nothing happened. Be calm, he told himself. The nanobots have to settle before the work begins.
Steve took his pants and shirt off in preparation. He had bought some jock clothes in varying sizes since he wasn't sure how well it would work.
He caught a glimpse of his bicep. It was trembling; no, it was swelling. It worked! Soon his bicep was the size of a softball. Then his other bicep did the same. Steve glanced down at his chest; his pecs were starting to jut out further and further, getting to the size of watermelons. His shoulders broadened while his hips contracted. His skinny but pudgy stomach carved itself into 8 stone-hard abs. His chicken legs swelled into thick thighs and calves. His hands and feet grew to match their corresponding limbs.
