fumarate?

[genaro]

Hi people, I'm back (quite sometime I hadn't been around here)

Lots of things seem to have happened since my last visite...inlcuding many new RC's showing up.

But my question is about 'fumarate'.
I don't get why many RC's that used to come as hydrochlorides are now coming as fumarates.
Does it affect the conservation of the product? (meaning that it could be stocked for longer period?)
Does it affect the chemical reactivity/stability of the material?
Does it affect significantly it's boiling point (so maybe it could be smoked while HCl salt cannot)?
How does it affect the dosage (how many % heavier than the HCl salt)?
Does it affects the effects in any way (I suppose not) ?

By the way, hydrochloride is the 'HCl' salt, fumarate is the ?what? salt


PS: I was also seraching for the RC surveys...are these grouped together somewhere in the forum?
