I saw this movie in the late 90's. It looked like an independent Sci-Fi movie. There were a group of teenagers in an underground lab or something and they used a drug or something to attain superhuman strength. One girl used it and her body couldn't handle it and she exploded. Another guy used it and his body could handle it and he crushed a pool table ball with one hand. There was one guy in the group that became the villain, and there was a good guy in the group with his girlfriend. The good guy had superhuman strength as well(obviously), and he had to go up against the bad guy to save himself and his girlfriend. The more pissed off the bad guy became, the bigger his head got and he seemed to mutate but he could still talk. The movie was in english, but it looked like it was probably made in Australia or New Zealand, mid or late 90's. Anyone know? Please?

Wow. Looks like this could be semi-pervo Larry Clark's Teenage Caveman from 2002.

Thank You so much. I'd almost given up. That was it! That's amazing. I'm pretty sure almost no one has ever seen this movie! Thanks again.
