THE MOOD MODULATOR
Melanocyte-Inhibiting Factor; PLG
MIF-1 (Pro-Leu-Gly-NH2) is a naturally occurring tripeptide derived from oxytocin that can cross the blood-brain barrier and influence your dopamine system. It shows rapid antidepressant effects in studies and may help with mood, cognition, and even Parkinson's symptoms. It's also being researched for helping reduce opioid dependence.
