Serious calories for hard gainers
Mythic Mass is a New Zealand-made mass gainer from Pack Nutrition, built on a maltodextrin carbohydrate base with a whey protein concentrate and buttermilk blend. One full serve delivers 1267 Cal, 50 g protein and 250 g carbohydrate — and it is designed to be split across the day, not slammed in one giant shake.
- 1267 Cal per full serve — a high-calorie, carb-forward gainer to help you hit a daily surplus when eating enough is hard.
- 50 g protein per full serve — a whey concentrate and buttermilk blend to support muscle recovery and growth alongside resistance training.
- 25 g essential amino acids — all nine EAAs per full serve, including around 12 g of BCAAs and 5.7 g of leucine.
- Made in New Zealand — free from artificial colours and preservatives, with QR batch verification on every bag.
Built to be split, not slammed
Most gainers tell you to down 4–5 scoops at once. A single 1267 Cal shake is a lot to stomach — it can leave you bloated and too full to eat the real meals that actually build the surplus. Impressive on the label, awkward in real life.
Mythic Mass takes the opposite approach. The full 333 g dose is there when you want it, but it is designed to be broken into smaller servings — one at breakfast, one post-workout, one as a snack — so you top up calories through the day without overloading a single sitting.
A gainer supplements meals, it does not replace them. Spacing your intake gives your body more time to digest and use the nutrients, and keeps room for whole food. Every number is printed on the panel: 1267 Cal, 50 g protein, 250 g carbohydrate and 25 g EAAs per full serve.
Build smarter, not harder — a mass gainer that fits how you actually eat.

How to use
- Start with 2 scoops. Mix 2 scoops (148 g) with about 566 ml of cold water and shake for 10 seconds.
- Scale if you need more. For a bigger hit, step up to 2.5 scoops (208 g) with around 800 ml of water after training.
- Spread it out. Split your daily intake across the day — for example one serve at breakfast, one post-workout and one as a snack — rather than one giant shake.
- Use with real food. Treat it as a top-up between meals, not a meal replacement, and adjust servings to your own calorie needs.
