Syntha-6 Protein 2.27kg for Recovery and Daily Protein Intake
BSN Syntha-6 is the brand's flagship multi-source protein blend built for trainees who want a slower-digesting protein with a thicker, dessert-style texture than a standard whey shake. Each 47g serving delivers 22g of protein at 185 calories, with 6.5g of fat, 6g of carbohydrates and 5.7g of fibre. The 2.27kg tub provides 48 servings.
The protein blend combines six sources: whey protein concentrate, whey protein isolate, calcium caseinate, micellar casein, milk protein isolate and egg albumen. This multi-fraction approach provides a mix of fast-absorbing whey fractions for immediate amino acid delivery and slower-releasing casein and egg fractions for sustained delivery over 4-6 hours. The 5.7g fibre per serving sets it apart from most pure-whey blends and contributes to the dessert-like texture and satiety profile.
What separates Syntha-6 from a standard whey is the multi-fraction protein blend and the indulgent flavour profile. It is positioned as a meal-replacement style protein - dessert flavour, thick texture, sustained release - rather than a lean post-workout shake. The 185 calories per serving reflects this; trainees on tight cut macros choose a different format. The BSN brand legacy and global retail presence add brand-recognition value.
Syntha-6 2.27kg suits trainees who use protein shakes as meal replacements or evening shakes, lifters who want a fuller-flavour protein over a clean whey isolate, and those who prefer multi-source blends over single-source whey. Not the right pick for trainees tracking macros tightly in a cut phase or who specifically want fast-absorbing post-training protein. Contains milk, soy and egg.
Lean alternative: Applied Nutrition Critical Whey 2.2kg delivers 24g protein at 130 calories per 33g scoop - a faster-absorbing whey blend with lower fat and calorie load for cut-phase use.
