L Carnitine, BCAA's and etc

hey,
i take a scoop of BCAA's (leucine/ isoleucine and valine) and
i take a multi-vit in the morning loaded with Vitamin C and i take a Cod Liver Oil + Calcium tablet

i take an all-in-one protein shake after exercise and
i take a multi-vit/ immune support in the evening after dinner

and i take a Supp by LA Muscle called Norateen (a natural Test Booster) 3 x a day.

The Multi-Vits, i like to think have helped support my health in that i cannot remember the last time i had a cold or flu.
The BCAA's and all-in-one protein shake, i like to think have helped support strength and muscle gains and i'm pretty damn sure have eased the usual DOMS i used to get after particularly heavy and hard weights sessions.
And the T booster i like to think has given me an added boost in that i can go harder and longer than i used to in the gym and i think has helped me push past what i considered a strength (and weight/ ie. not being able to gain) plateau.

NOT L-carnitine, that's for sure.

Why not?

Cod Liver for Omegas and Vit A and D
CoQ10 for expression
B12 for Expression
BCAAs for LBM maintenance while cutting
Creatine Mono with Apple juice for the extra oomph
N-Pept 10 for focus (will be switching to ALCAR after this)

Mainly looking at the foods that contain it. I don't like the fact he doesn't reference any studies to back up his writing.
