[Hairy]

As the title says. I'm looking for more info to see what is safe to use when expired and for how long it will be effective.

I'd like to find out if anything degenerates into harmful substances with age, and whether or not certain meds will maintain useful potency for a while.

I ask this because the farthest I've seen exp dates go is about 2 years.

Thanks!

A doc i worked with told me they just get less potent with age. Loads of expired meds make their way to africa every yr and are used.
