I'm using NOW Amino-9 Essentials Powder. It's basic, unflavored, reasonably priced, and has all 9 EAAs in transparent amounts and "in the proportions recommended by the National Academy of Sciences to optimize protein synthesis and tissue repair for adults age 19 and over." (quote is from their website).
You could still use TN and maybe add 400mg histidine per 10 gram serving.
I think this is the same amino acid profile as TN.
