Fitness Model Morph 3

So the thing about Noah was that fitness was his entire life. Almost a third of his existence was spent in the campus gym, and in the seven years he had been lifting since high school, he had bulked considerably and had the ripped physique that every girl lusted over and every guy envied for. Still, the desire to be absolutely massive was too strong for him to overcome. As a result, he signed up for the research project his girlfriend Charlotte was a part of the biology department. 

After she and her team had moved past animal testing, the next phase involved human trials, even they only had enough funding to allow for three test subjects. The first two had failed to have their muscles grow from the serum they had synthesized to act as a substitute to steroids that would provide the same muscle enhancing properties without the side effects. The last subject was her boyfriend, who she knew was beefy enough to begin with, but it wouldn't hurt to at least try it with someone who was already quite muscular. Maybe the excess testosterone in his system would interact with the serum to produce the desired effect. 

Once the serum was administered, she knew that it was working, and all her team's hard work was going to be paid off. Noah's entire body inflated to twice its original size, and caused the shirt he was wearing to burst off his body. In a state of pure excitement, he pulled down his sweatpants and gave an impressive double-bicep pose. While standing there, he gave Charlotte a suggestive smirk. She finally noticed when he was in his underwear that the serum had caused more than just his muscles to inflate to incredible proportions.
