Oxytocin
Shop OxytocinOxytocin is a peptide, which means it is a short chain of tiny building blocks called amino acids. Your body makes it naturally. It is a hormone, a kind of messenger that tells parts of your body what to do. Doctors have used it for many decades, and it is one of the best-studied peptides there is.
The most well-known job of oxytocin is helping with childbirth. When a mother goes into labor, her body releases oxytocin to make the womb squeeze and push the baby out. Doctors can also give a lab-made version during childbirth for the same purpose. It also helps with bonding, emotional connection, and social feelings.
Scientists count it among important natural messengers like insulin and endorphins. Because oxytocin has been used in medicine for a long time, its safety is better understood than most research peptides. It has gone through the normal drug approval process in its medical uses. Still, taking any hormone when you do not need it can cause problems, such as too-strong womb contractions. Anyone thinking about using it should talk to a doctor first.

mg vs mcg: one milligram (mg) equals 1,000 micrograms (mcg) — multiply by 1,000 going from mg to mcg, divide by 1,000 going from mcg to mg. Mixing the two up is a thousand-fold dosing error: 1 mg taken instead of 1 mcg is a 1,000× overdose; 1 mcg instead of 1 mg is a 1,000× underdose. Always double-check the unit label and the decimal place.
