BSN SYNTHA-6 is one of the best-tasting protein powders on the market — but it comes at a nutritional cost. Higher in calories and fat than most whey proteins, it's more of a meal replacement than a post-workout shake. Is it right for you?
Why We Reviewed BSN

Our Verdict
SYNTHA-6 is the protein powder for people who think protein powders taste terrible. It's not the leanest option, but for flavor and satiety, it's hard to beat. We give it a 4.2/5 and recommend it for those prioritizing taste, people in a muscle-building phase, or anyone using protein as a meal supplement rather than a pure post-workout.
