I know I am not Ulter, but I can take a stab at this:
Mass Aminos are basically just added protein. I see per serving they add 5 of protein. I would rather eat chicken or take a protein shake that has 30 of protein instead of taking 4 pills to add only 5g. When I started training many years ago, it seemed aminos were the rage. The only aminos that I think are remotely important to supplement seperatly are BCAA's. Even then, to maximize the effect you really need a great deal...10-20g or so...which is very expensive.
Anafit has the Protein ISOAGB which is very rich in BCAA's and also Acetyl-L-Glutamine which will enhance recovery. In my opinion, it is a lot better option than taking Amino Tabs.
As far as the Liver tabs, I know anafit doesn't have anything like that. Bodybuilders in the 60's and 70's lived on them. It was popularized by Vince Gironda and it was ahead of it's time. I have actually used the Liver tabs from Bev and I like them. They do add extra B Vits and protein and I actually feel better taking them. I am not sure if that is only because I THOUGHT they were working, but I did feel better. The only thing I didn't like is taking all those Fing pills all the time.
I honestly think you would be better served with the ISOAGB then either the liver or amino tabs. I am sure Ulter and Mac will add something more.
