When you find yourself trying to remember a show (or any works) that's on the tip of your tongue but just out of reach, come here - the collective brain of the TVTropes community can probably help. Post all the details you can remember (examples help). If you're looking for a trope, head over to Trope Finder. Have general questions about tropes? Visit Ask The Tropers!
What your description brings to mind is the scene from Hollow Man where the guy gets injected with blue fluid and thrashes around violently while turning invisble from the outside in. That's probably not it, but just in case.
I hope this is okay, but I'm bumping this decades-old query to confirm that it is Hollow Man. Belated thanks to PaulA!
"YOU ARE KAIND. MERSIFULL. AND, MOAST OF ALL... YOU DOAN'T KNOW HOW TO CLAIMB."

In this 90s-00s movie, a team of scientists makes a human from scratch by injecting blue fluid (possibly deoxygenated blood) into a nonexistent body. However, an accident causes the human to become savage and decompose. There are also dogs that are kept for experiments. What's that title again? It's at the tip of my tongue!
