I have recieved a message responding to what I posted above and I have just read this message. I am low in all amino acids bar about 3, that includes essential and non- essential. I eat loads of garilc because that actually makes me feel better as does taking methionine and cysteine. I have been on pure amino acids all of them for 4 years with no change in my levels. I am interested in your stroy and how you got into this.
