"Whew! That's strong. Probably put hair on my chest!" she gasped. She was right. It did put hair on her chest and then some. She let out a yelp as she grew bigger, and suddenly felt a bulge in her panties. She dropped her glass and feather duster and ran out of the laboratory. She dashed into the bathroom and stared at the masculine face staring back from the mirror. She tore off her clothing. Good grief, she had the body of 1950's buff bodybuilder. Male bodybuilder, she noted pulling open her panties and examining her new equipment. "I wonder if it's permanent? Maybe there's an antidote?"
Alice ran back to the laboratory, and discovered his new strength. He pushed the edge of the table to move it an inch, and it slid across the room hitting the cabinet on the far wall.
"Dang, I'm strong. Hm, I bet I could clean this whole place in a couple hours with this body. It probably won't last anyway."

The glass beakers, test tubes, tubing and cabinet doors all shined. The steel and chrome devices gleamed. The laboratory even seemed brighter thanks to Alice's elbow grease. She was only wearing her panties still, and was surprised to hear a voice behind her.
