Fake product
Verolabs is selling oxytocin also called the "Love Hormon".
Small bottle with - sometimes - big placeboeffect.
According to verolabs it should be applied on the cloth.
On the website no indication of what actually is in the bottle.
Anyhow:
"Synthetic oxytocin is sold as proprietary medication under the trade names Pitocin and Syntocinon, and as generic oxytocin. Oxytocin is destroyed in the gastrointestinal tract, so must be administered by injection or as nasal spray. It has a half-life of typically about three minutes in the blood, and given intravenously does not enter the brain in significant quantities – it is excluded from the brain by the blood–brain barrier. Evidence in rhesus macaques indicates oxytocin by nasal spray does enter the brain. Oxytocin nasal sprays have been used to stimulate breastfeeding, but the efficacy of this approach is doubtful."
Unless you're spraying that stuff directly up someone's nose as they inhale then they're getting circa 0% of the effect.
