Is it possible to create a chemical strong enough to imitate the abilities of your adrenaline. And for those of you that know about adrenaline shots please understand I'm talking about something total different from adrenaline shots.Even if this creation had a 40% chance of killing you, can it still be done ? And if so how many hours will it last before you would need more ?

Second question, is it possible to create something that repairs cells at almost an abnormal rate(faster).Not talking steroids will a protein flood.
