Just wanted to know how much phenylephrine is safe to ingest. As it is insoluble in water cwe does not work on it, and i want to extract some codeine from some C and F tablets. They contain 5mg Phenylephrine, 9.5mg Codeine, and 500mg paracetamol, im guessing its inclusion is an attempt to deter us recreational users rather than an alternative to Pseudoephedrine as they claim. Planning to take a dose of about 150mg of codeine, which would amount to 80mg of Phenylephrine
