James was kind of a skinny nerd. He'd come to sign up for some kind of trial to get some money for college. It sucked, he was always broke, he couldn't afford to do stuff. And even if he could, he wasn't super popular, he was a tall, pale, nerdy guy, not very social.
But one of the trials caught his eye for that reason. Perfection Protein Powder, in its alpha testing phase. This exercise supplement was guaranteed to give you your ideal body.
After handing the forms back to the receptionist, she smiled. "Excellent, sir! If you'll just wait here a moment, I'll fetch one of our staff!" She bustled off, leaving James to twiddle his thumbs. After about fifteen minutes, watching a rerun of Modern Family on the TV in the corner of the waiting room, a man with spectacles and a lab coat appeared.
"James? Excellent, come right this way." He was led into a small room, with a chair and a two-way mirror. Clearly, he'd be observed. A small table had a glass on it, and in the glass, some kind of protein shake. Bizarrely, he was asked to strip off and leave his clothes with an orderly. Embarrassed by it, but figuring this was a medical facility, so it wasn't so weird, he went along with it.
"So, if you just drink that, and sit for a while, we'll be waiting," explained the doctor, before closing the door. James shrugged, drinking the drink. It tasted great, rich and creamy and caramel-y, leaving a warm rich glow in the gut.
