Friend makes killer homemade lean. But he can only do large batches and wants to store and use throughout the year. I know Pharmacy lean expires but that's Codeine HCL? How long would it take for straight Codeine/thats been CWE "expire"? Years? Months? How long would it last in a dark place with constant 16 degree temperature? And what would be ideal conditions for storage?
THANKS PEOPLE!
