Halo is too toxic for my blood. Never used it.
It's double methylated -- 17 AA PLUS contains Alpha Chlorine, PLUS it contains an isozyme (can't remember the chemical name at the moment) that not only strains the liver, but the kidneys as well.
PLUS, it can have an adverse effect on eyesight for some reason.
And just as a kicker, it destroys glutathione, which also helps to protect the liver. So not only are you slamming the liver three times as hard, it's also compromised in the way it can protect itself.
Halo is good for fighters and football players who want a surge of strength and aggression for a couple of hours. As for long term use, it's a ticking time bomb.
There's no "reset" on the liver or kidneys. Once they go, you're dead.
Sorry to be a bummer. Just sayin it like it is.
