Halo... can you use it in Comp

[mmaximus25]

I don’t know much about power lifting comps in fact I'm going to post this in the Power lifting arena. So please reply there if you’re a competitive Power lifter

I use halo every other week to every 2 weeks (twice in the same week for legs and chest) when I do my most powerful and heaviest lifts.

Do they test right before you walk out to lift... how does it work? Cause 8-10mg of halo allows me to easily add 40-70lbs to any bench and 100-200lb on leg press, squats and deads. This really helps me cause on heavy days I do gut busting drop sets. Let’s get it on

I'd like to add I dont use Halo when trying to gauge my strength on average.
