Hey guys, long time lurker first time poster 
In regards to a CWE of panafen plus (12.8mg codeine, 200mg ibuprofen).
After making a batch, depending on the amount I make, how long will it stay good to drink if left in the fridge?
And another more scientific question: Who figured out that the white gunk left in the filter paper is more so the binders than the codeine itself?
Ive always wondered how exactly and why it is mostly codeine that seeps through the filter paper and the binders such as the ibuprofen/paracetamol are the ones that get stuck in the paper?
Hope I posted this thread in the right spot.
