So i got a couple of different 'types' of fumarate.

1- Fumarate from lazy tek, very pure but taste horrible like d-limo,(cant get it out with IPA wash)
2- Freebase conversion to fumarate that is very sticky and yellow

Basicaly what i would like to know what the different effects are of fumarate.

So what is the effect of yellow fumarate and what of pure white?

Cheers,
V

I havent noticed any difference in effects from the different fumarates when ingesting them orally.
