Life extension

I give you life, more of it, and you will feel more alive than you have ever been, to be young again, to be full again, who wants partially filled? And there is no more need to question on riddles and paradoxes for white and black have been restored, the definitions clearly marked, muscles powerful, exude charisma, pheromones, become the dream, all I ask is a little blood, the more innocent the better.
