▲ Fill a graduated cylinder with 50 ml of distilled waterthen pour into a 4oz glass jar;
▲ Drop in one 50mg Naltrexone tablet.
▲ The tablet will mostly dissolve in about 2 hours - Note that not all of the tablet is soluble in water so instead of yielding a clear solution, the result will be a cloudy suspension.
▲ One ml of the SHAKEN suspension will contain one mg of Naltrexone
▲ Use a graduated baby medicine dropper or 5-ml syringe to measure out the dose you need.
Since liquid form has a dramatically decrease shelf life, do not make more than 50 ml of liquid Naltrexone at one time, store it in the refrigerator, and do not keep it for more than 2 months.
Be sure to shake the liquid LDN well before using and keep from direct exposure to sunlight.
