Oxytocin
Oxytocin is a nano peptide hormone that is secreted by the posterior pituitary. Oxytocin produces a wide range of effects both peripherally and locally in the brain. It is released in large amounts in females during childbirth, nipple stimulation, and breastfeeding. Oxytocin is released by males and females during skin to skin contact, sexual arousal, and orgasm/ejaculation. Additionally, it plays a role in bonding, desire, social recognition, and trust, and is therefore known as the “cuddle” hormone.

The best way to take oxytocin is sublingual oxytocin. It is a dissolvable tablet that you put in your mouth. This form is much better for sociability and sexuality, making orgasms much more intense. This quickly absorbing form of oxytocin isn't absorbed much through the mucous membrane and permits a quick and stable action.
