I apologise if this has already been answered but I've been pouring over as much of the forums and literature as I can and haven't exactly found what I need so I would appreciate any help with a couple of questions. Even if you think I should avoid clen, I would still like to learn how it would affect me.
Most places say that clen is safe in low doses however can be lethal to anyone with undiagnosed heart conditions, so I would like to know if there is anyway to compare clen to caffeine.
-What I mean is that since both clen and caffeine target beta-2 receptors would any of the possible negative side effects of clen be present in caffeine too? or would the potential heart issues come about from beta-1 activation by clen?
-caffeine has never been a problem for me, I remember back while cutting I would take maybe 300-600mg of caffeine from fat burners and preworkouts, so if I had a potentially dangerous heart condition would that amount of caffeine have triggered an attack and since I am still fine would it be safe to assume clen would be okay? or should I still avoid it?
-or is it due to the raised body temperature, sweat and ion imbalance that results in heart issues?
oh I don't know if age would be a factor in this but I am in my 20's if that makes any difference at all.
I have also posted this on another forum too just to gather as much info as possible
