Mass Gainer Protein: buying guide

Who uses a mass gainer?

  • People with a fast metabolism or small appetite who find it hard to eat enough calories.
  • Anyone in a bulking phase who wants an easy extra 600 to 1,200+ calories a day.
  • Busy people who need a convenient high-energy snack between meals.

How to compare mass gainers

  • Calories per serve: some gainers are 600 calories, others over 1,200. A full serve can be several scoops.
  • Protein to carbohydrate ratio: "lean" or "clean" gainers have more protein and fewer calories.
  • Carbohydrate sources: look for oats, rice or highly branched dextrins if you prefer less sugar.
  • Serves per bag: a 5 kg bag can be fewer serves than you think, so check price per serve.

If you only need extra protein, a regular whey protein is cheaper. Many people also add creatine while bulking.

Order online with Australia-wide delivery, free on orders of $100 or more, or visit a Supps247 store in Melbourne, regional Victoria or Brisbane to compare tubs in person and taste flavours before you buy. Members can use our price match guarantee on full-priced items.

Always read the label and follow the directions for use. If you have a medical condition, are pregnant or take regular medication, check with your doctor first.

Mass Gainer Protein: questions and answers

Do I need a mass gainer to build muscle?
No. Training and eating enough calories and protein are what matter. A gainer is simply a convenient way to add calories if you struggle to eat enough food.
Can I take half a serve of mass gainer?
Yes. Many people start with half a serve to see how they handle it, then build up. Splitting a serve across the day can also be easier on the stomach.
What is the difference between a mass gainer and protein powder?
Protein powder is mostly protein with few calories. A mass gainer adds a lot of carbohydrate, so a serve can have several times the calories.
When should I drink a mass gainer?
Between meals or after training works well for most people. Drinking it right before a meal can spoil your appetite for real food.
