EHP Labs also markets OxyShred Hardcore as a pre-workout, so here's how it holds up against that standard — and the picture looks very different.
Energy and focus are both genuinely strong, driven by a high caffeine dose plus real carnitine and theacrine support.
But there's no citrulline, arginine, nitrates, beta-alanine, or creatine anywhere in this formula, so don't expect any pump or strength benefit at all.
This is the same product reviewed under Fat Burners on this site, where it performs considerably better, since fat-burning and appetite are things it actually attempts.
Honest take: Expensive and mismatched for what it's marketed as — this is really a fat burner, not a real pre-workout.
