Editor's Supplement Pick: BPI Pump-HD

Getting a pump isn’t just important for vanity—it’s also a sign of a good workout. It means that your muscles are well hydrated and filled with nutrient-rich blood that will help them grow.

BPI’s pre-workout formula, Pump-HD, helps the cause in two ways, with caffeine anhydrous (more powerful than the caffeine in coffee), so you’re alert and fired up to do longer, harder sets; and a unique blend of electrolytes, creatine, beta-alanine, and leucine. It’s among the best-tasting pre-workout powders we’ve tried (Peaches n’ Cream is our favorite), and, for reasons we’re not quite sure of, it seemed to help us keep the pump for longer than normal after training.
