Zombie Labs Gainz

A mass gainer for people who genuinely struggle to put weight on. A four scoop serve gives you 673 calories and 35 g of protein, and the carbohydrate comes from oats and sweet potato rather than straight sugar. There's 3 g of creatine and a digestive enzyme blend in there too, so it's doing a fair bit in the one shake. Mix it with a litre of milk and you're closer to 1830 calories.

• 35.2 g protein per 160 g serve, from milk, egg white, whey isolate, whey concentrate, collagen and PhytoPea
• Wholefood carbohydrate from maltodextrin, oats and sweet potato
• 3 g creatine and 3 g BCAAs per serve
• Added glutamine and DigeZyme digestive enzymes
• Fats from coconut oil, MCT and olive oil

Mix 4 scoops (160 g) with 500 to 700 ml of water or milk, after training or between meals. One or two serves a day.
