Endure x and super charged collagen are a perfect pair. I drink endure x with super charged collagen every morning. And again before pm training. Collogen itself is very hard to get down but mixing with endure x you get the benefits of both supplements in one 16 oz drink. Be more mindful of the breaks you take. I find myself hoping back onto my project with very little rest or fatigue. I also take the crush pills 30 minutes before I go the gym. The crush pills help you feel alert and energetic with no tingles jitters or any real negative side effect, way more cost effective than bang or a coffee before every session. 10/10 will be purchasing more of these products.
