RCs MPH vs EPH age old comparison question.

[Wilso]

So, i have personally used both MPH and EPH a lot (MPH prescribed). For years i've been searching for actual opinions and hopefully some facts about the similarities and differences between the two. I know there's hundreds of posts asking this same thing on the internet, but it's always a hazy, half-cop answer. So if you have ever tried both, or you know the scientific similarities and differences please post below withe the intention of being as clear as possible. Everything and anything you know in relation to comparing the two. This thread is largely for the sake of harm reduction as we all know that EPH is a lot cheaper. I really appreciate your help!
