Glycer65 by Blackmarket Labs is a 65% standardized glycerol powder delivering approximately 1.3g of active glycerol per 2g scoop. Glycerol acts as an osmolyte, drawing water into muscle cells for hyperhydration-driven pumps and improved endurance during high-volume training. Unflavored and stimulant-free, it mixes cleanly into any pre-workout or beverage for stackable pump support. 100 servings per container.
