best stack for cutting

[soshiv]

what is the best stack for fat burning...
Ephedrine, Caffeine, Aspirin
or
Ephedrine, Caffeine, Yohimbe, L-Tyrosine

which combination will help me to burn the most fat combined with my HIIT and bike riding and which brands of each compound does everyone use or works the best?

[soshiv]

also what about acetyl l-carnitine? would it hurt to throw some of that in there with everything else?

[soshiv]

one last thing... how much of each compound is optimal?
