Rebound XT™, which contains the ingredient ATD (3,17-Dioxoetioallocholan-1,4,6-triene), can be used either as the core of a post (pro)hormone cycle therapy (PCT) plan, or as a stand-alone, to raise/restore natural testosterone levels and decrease estrogen levels. For best use, combine it with Lean Xtreme™ for a well-rounded PCT Stack that lowers estrogen, controls cortisol, and boosts natural testosterone production, or with ActivaTe™ to make up the heralded NHA Stack™ - the remarkable non-hormonal, mass-building, anabolic stack.
