The bottom line: it delivers an unusually dense calorie and protein payload to support rapid size increases, with 1,340 calories and 50 g of whey protein per serving that make it best for serious mass-building phases. The blend of whey, creatine, BCAAs and glutamine gives it a complete recovery profile, while third-party banned substance testing offers extra confidence for competitive athletes.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-calorie formula:\u003c\/strong\u003e Each serving supplies 1,340 calories to help users push daily energy intake well above maintenance for rapid mass gain.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtein-rich:\u003c\/strong\u003e The powder provides 50 g of high-quality whey protein per serving to support muscle growth and repair after intense training.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCreatine included:\u003c\/strong\u003e Contains 1 g of creatine to help support muscle energy production during demanding workouts.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmino support:\u003c\/strong\u003e Delivers naturally occurring BCAAs and 10 g of glutamine to aid recovery and support immune and muscle health.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBanned substance tested:\u003c\/strong\u003e Third-party testing for banned substances increases trust for athletes concerned about contamination.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe Bulk 1340 is aimed at experienced lifters, athletes in a mass-gaining phase, and anyone with a very high daily calorie need who struggles to consume enough food.
