Hi Folks, So I'm pretty sure I need L-carnitine. The problem is here in Canada you cannot buy L-carnitine, nor can you order it on-line from the States. It gets stopped at customs. Has anyone tried the L-Carnitine precursor, 'GBB' (gamma-butyrobetaine )? It seems I can get this in Canada, and I trust the brand, AOR. Here is the info: http://astronutrition.com/aor-precar-l-carnitine-precursor-750-mg-60-vcaps.html Thanks!
