Zombie Labs Gainz Mass Gainer
Product details
On this page
Zombie Labs Gainz is a whole-food mass gainer for people who struggle to eat enough to grow. One full serve (4 scoops, 160 g) gives you 673 calories, 35 g of protein and 100 g of carbs from oats, sweet potato and maltodextrin, plus 3 g of creatine, BCAAs and digestive enzymes. Mix Gainz with milk and one shake tops 1,000 calories. Choose a 1.6 kg bag (10 full serves) or a 4.32 kg bag (27 full serves) in two flavours.
Why choose Gainz mass gainer
Zombie Labs made Gainz as a powerful whole-food mass gainer, giving you 673 calories per serve from whole-food proteins, complex carbs and healthy fats. Every serve has 35 g of complete protein, plus creatine and BCAAs for muscle growth and recovery. Gainz also has a digestive enzyme blend to improve absorption and reduce bloating, a common problem with big gainer shakes. Mix Gainz with milk for a thick, creamy, high-calorie shake in bold chocolate or vanilla.
What Gainz helps with
- Gaining weight: 673 calories per serve, more than a lot of full meals.
- Building muscle: 35 g of protein from whey, pea, collagen and egg white, plus 3 g of creatine.
- Training fuel: 100 g of carbs from oats, sweet potato and maltodextrin to refill your energy stores.
- Easier digestion: DigeZyme® and five digestive enzymes, including lactase for the milk protein.

What's in Gainz
- Multi-release carb blend: maltodextrin for fast energy, plus oats and sweet potato for slower-release carbs.
- Whole-food protein blend: whey protein concentrate, PhytoPea™ pea protein isolate, hydrolysed bovine collagen, whey protein isolate and egg white protein.
- Super fat blend: coconut oil powder, MCT oil powder and olive oil powder for extra calories.
- Amino blend: micronised creatine monohydrate, BCAAs, glycine and glutamine.
- Digestive enzymes: DigeZyme® (amylase, protease, lactase, lipase and cellulase).
How to take Gainz
To start: mix 4 scoops with 500 to 700 ml of water or milk in a shaker or blender. For full impact: hard gainers and high-volume lifters can have 2 full serves a day (8 scoops), split into two shakes, for example one after training and one between meals. If 4 scoops feels like too much at first, start with 2 scoops and build up.
Water or milk?
With water, one full serve is 673 calories. With 500 to 700 ml of full cream milk, the same shake comes to roughly 1,000 to 1,130 calories and about 52 to 59 g of protein. Use milk if you're a hard gainer, and water if you want a lighter shake or are watching your fat intake.
2 flavours
- Chaotic Chocolate
- Vicious Vanilla
Not sure which to pick? Gainz is covered by our Love the Taste Guarantee. Try up to 5 serves within 30 days. If you don't love the flavour, swap for another or take store credit.
Which size?
The 1.6 kg bag is $79.95 for 10 full serves (about $8.00 a shake). The 4.32 kg bag is $159.95 for 27 full serves (about $5.92 a shake), so the big bag saves you about 26% per serve if you're having Gainz every day.
What to take with Gainz
- A pre-workout: Zombie Labs End of Dayz or the stim-free Zombie Labs King of Pumpz to train hard enough to use the extra calories.
- Extra calories on the go: the EQ Food XL1000 Cal Protein Cookie packs 1,000 calories into one cookie.
- Creatine: Gainz already gives you 3 g of creatine per full serve, so you don't need a separate creatine on days you have a full shake.
Who should take Gainz?
Gainz is a good fit for hard gainers, skinny guys trying to bulk, and high-volume lifters who can't eat enough food to grow. Gainz suits anyone who wants a mass gainer with whole-food carbs and digestive enzymes instead of a shake that's mostly sugar.
Side effects and who should avoid Gainz
A big shake can make you feel full or bloated at first. Start with 2 scoops, sip the shake rather than drinking it fast, and build up to the full serve. Gainz contains egg, gluten and milk, so Gainz is not suitable for people with those allergies or with coeliac disease. Gainz is high in calories and saturated fat, so only use Gainz if you're trying to gain weight. If you have a medical condition, check with your doctor first.
