DMAA (1,3-Dimethylamylamine, also known as methyl hexaneamine (MHA), and several other names) has rarely been out of the headlines in recent months since FDA issued warning letters to 10 manufacturers and distributors of supplements containing DMAA.
There has been intense debate about whether DMAA, which was first manufactured synthetically by drug giant Eli Lily in the 1940s, is in fact a constituent of geranium.
The new warning letter is identical to the ones sent by FDA earlier this year.
