Overview

BSN SYNTHA-6 is widely regarded as the best-tasting protein powder ever made. The formula uses a multi-source protein matrix (whey concentrate, whey isolate, casein, micellar casein, egg albumin, and milk protein isolate) that provides both fast and slow-digesting proteins for sustained amino acid release. Each serving provides 22g of protein with 5g fiber and 200 calories. The higher calorie and fat content compared to pure isolates is what gives SYNTHA-6 its legendary milkshake-like taste and texture. Chocolate Milkshake and Vanilla Ice Cream flavors are industry benchmarks for taste.

Our Verdict

8.0/10 — Very Good

BSN SYNTHA-6 is the protein powder for people who hate protein powder. The taste is genuinely exceptional — Chocolate Milkshake tastes like an actual milkshake. The trade-off is higher calories and lower protein per serving. If taste is your #1 priority, nothing else comes close.
