Low-Dose Naltrexone (LDN) 

Available in capsules, transdermal cream, oral solution, sublingual drops, and topical dermatological formulations

LDN is a competitive opioid receptor antagonist. At the standard dose, naltrexone blocks the effects of both the endogenous opioids, which are in endorphins and pharmaceutical opioids. LDN is a pure antagonist, which is vital to know as a lot of people think it is a controlled medicine, narcotic, or an opioid.
