Hello, Still trying to find out the sameness or differences between liquid deprenyl citrate and eldepryl. If they're the same thing why is one possibly more dangerous than the other? Is it really just dosage because one could be very careful. Also one is fda approved and the other isn't. Based only on dosage? That doesn't make logical sense. There must be a difference. For those of you taking eldepryl, is it in addition to or instead of sinemet? Thanks for any help you can give. Den
