Dustin decided to drink a little sip. He slowly tipped the liquid into his mouth, and then quickly stopped. It tasted strange, but not that bad. It actually tasted nice. He smiled, relieved that he didn't have to worry anymore about the situation.
He put the vial back into the container, and started to sit back and relax, watching his favorite show. After a little bit of watching the show, he felt a strange tingling sensation overwhelm his body, for just a second, then stop. Dustin paused his show, not sure what to think of the situation.
He felt another force go over his body, and then all of a sudden, he felt his hair lengthen in size. He felt odd, almost, excited, as his hair grew from a nice short buzz cut to a spike-able height. Then, he felt his muscles expand and grow.
His muscles bulked slowly and his waist pushed out towards his belt.
He could feel his backbone slightly shift, and he felt stronger, able to do more than before. He stood up, and found it much easier than it used to be. He then discovered how tall he was. He was almost an inch taller, and he almost instantly went to the scale to check his weight.
He used to be 160 Lbs, but now he was 170 pounds! It was something small, but could it have really all come from that sip of the gorilla serum he took? He then ran downstairs, feeling great, and quickly went back to the box.
He stared at the potion he had taken a sip of only fifteen minutes ago. He smiled. He had to drink the rest.
