History and Usage: NO-SHOTGUN fuels episodes of physical intensity to induce insane muscle pumps that can lead to muscle growth. The biochemical and physiological response to NO-SHOTGUN when combined with intense resistance training causes extra trauma to occur to trained muscle. Greater resistance to muscle results in significantly increased internal pressure (the pump)…And as you know, the better the pump the greater the trauma caused to muscle-tissue. The end result: increased ability to build larger muscle!
