They would be looking for the ECA stack. But those days are long gone and everyone is looking for something that can replace it. Well welcome Hydroxyelite Pro, the DMHA/Caffeine stack. While other companies let the FDA intimidate them into not selling DMHA, Hi Tech pushed forward and offers this DMHA/Caffeine ingredient combo in Hydroxyelite!
