Monster Serum

The Monster Serum is a drink that increases a user's speed and strength way beyond human limits.

History
Old Man Steven found the Monster Serum in The Quantum Laboratory, along with a cloning machine.

Origin
Apparently, the Monster Serum was never perfected due to an accident that happened in The Quantum Laboratory. It has been confirmed that it makes the consumer's heart beat way faster than the human limit. However, due to the fact that Old Man Steven came back from the dead, he can use it freely.

Duration
The Monster Serum lasts for about 15 minutes.
