More about Pro Series Super Size Ultra

MAX’S Pro Series Supersize Ultra is a premium high-calorie mass gainer designed for athletes and hard gainers who need extra fuel to build size and strength. This formula delivers a powerful combination of protein, carbohydrates and key recovery nutrients to support muscle growth and post-training recovery. With over 1200 calories, 60 g of protein and 200 g of carbohydrates per serve (when mixed with milk), Supersize Ultra provides the nutritional support needed to help you achieve your size and strength goals efficiently.

  •  High-calorie mass gainer to support muscle growth and recovery.
  • Delivers 60 g protein and 200 g carbs per serve for sustained energy and repair.
  • Enhanced with creatine monohydrate to aid strength and performance.
  • Includes MCTs and amino acids to support lean muscle recovery and repair

Each serve combines a balanced Protein & Carbohydrate Blend of maltodextrin, whey protein concentrate, whey protein isolate, milk protein concentrate, sweet potato flour and waxy maize starch. This mix fuels muscles with fast- and slow-digesting proteins for sustained amino acid delivery, while complex carbs help replenish glycogen stores for recovery and performance. The Recovery & Growth Blend features creatine monohydrate to promote power output during training, alongside medium chain triglycerides (MCTs) for efficient energy. Added branched-chain amino acids (L-leucine, L-isoleucine, L-valine) further support muscle protein synthesis, and L-glutamine assists with post-exercise recovery and gut health. Available in delicious flavours like Smooth Caramel, Chocolate Fudge and Vanilla Ice Cream, MAX’S Supersize Ultra is ideal for athletes seeking a complete nutritional shake to complement intense training. Simply mix 2–3 scoops (approx. 240 g) with 500 mL milk or water post-workout or between meals to maintain a calorie surplus and support your size-building goals.

Nutritional Information

Directions of Use

  • Add 3 level scoops (Approx. 120g) to a blender or shaker with 4-500mL of cold water, milk (and milk alternatives) and blend or shake for 20-30 seconds until completely dispersed.
  • For the ULTRA Protein and Calorie hit, add 6 level scoops (Approx. 240g) to 500mL of whole milk. Dosage may be adjusted based on appetite or to meet training needs.
  • For best results, take 1-3 serves per day in addition to regular meals. Consume within 30 to 60 minutes after finishing exercise to support fast recovery.

Good, a touch sweet

Works well and sits fine in the stomach, which is the main thing for me. Half a serve is plenty if you are sensitive to sweet.
Steph L.Verified buyerHobart TAS

Been on Maxs for years

Have tried the cheap stuff and come back every time. Consistent batch to batch, which is what you are paying for.
Luke D.Verified buyerWollongong NSW

My partner stole it

Bought it for myself, now we go through two of them. Second order this month.
Nadia H.Verified buyerCanberra ACT

Flavour not for me

Nothing wrong with the product and the delivery was quick. The flavour I picked is just not my thing, so I will try a different one next time.
