Can anyone direct swim to where Malpa is discussed in PhiKal.  Swim Cannot seem to find it.

Maybee you are thinking of MALPHA?

It is on p718 of PIHKAL
well not this chemical entity, but ALPHA is mentioned briefly
 these are the benzyl amine (ALPHA) and N-Methyl
benzyl amine (MALPHA) derivatives

sort of like J and Methyl-J  Hmmm

and the Designer Drug Directory says it gets you fucked up and lacks honeys' powerful amorectic activity
