Oxytocin is a 9-amino-acid peptide hormone made in the hypothalamus and released by the pituitary gland.

[0:00]The ‘love hormone’… in a nasal spray? I would have saved a lot of time wasted on dinner dates.
[0:06]Oxytocin is a 9-amino-acid peptide made in the brain’s hypothalamus and released by the pituitary gland.
[0:12]Henry Dale described its effect in 1906. In 1953, Vincent du Vigneaud made it in a lab. It was the first peptide hormone ever synthesized, and he won the 1955 Nobel Prize for it. So it’s not new. It’s older than your grandma’s fondue set.
[0:28]Hospitals use oxytocin as a prescription medicine during childbirth. The famous nasal-spray studies on trust and social behaviour were mostly small, with mixed results. Researchers have openly questioned how much actually reaches the brain through the nose.
[0:44]The internet version is: instant bonding, confidence, charisma… If it worked like that, dating apps would sell it at checkout.
[0:51]A research spray is not the hospital drug, and it’s not for people. Same name, different everything.
[0:57]People even search “oxytocin Canada.” Honestly, most Canadians are already pretty cuddly.
[1:02]Real hormone, real Nobel Prize, and a lot of wishful thinking. If you’re researching oxytocin, read the studies, not the love-hormone headlines.
