I believe there is a thread in the nutraplanet section to let them know what you would like to see them carry

Also, here is a great description from the man himself (William Llewellyn) on why fish oil was included in the X-Factor Advanced formula as I know a lot of folks on this forum has been curious as to why it actually enhances their results."We really want the availability of FREE ARA during/after training; that is the focus... that is what builds muscle. So, membrane bound ARA is only good if you liberate it. I think short term cycles of ARA+EPA/DHA may do this: First, you have more ARA in serum during exercise (just from the ARA), which is why pre-workout probably works so well, and then the added EPA/DHA helps free up more of the stored ARA... Kind of addressing ARA endogenously and exogenously at the same time."
