What’s the best supplement for bulking up?

Progain is our go-to for mass gain — it combines high protein and high calories to support size and strength increases. Pair with creatine for optimal results.

How does creatine support strength?

Creatine increases the body’s ability to produce energy quickly, allowing for better performance during high-intensity lifts and training — ideal for strength and power phases.

Can I use strength supplements if I’m just starting out?

Yes — beginners can benefit from added protein and creatine to support recovery, muscle growth, and performance. Always follow usage guidelines and start with foundational products like Max Whey or Cyclone.

What’s the difference between Progain and Cyclone?

Progain is a high-calorie gainer designed for size. Cyclone is an all-in-one performance formula with creatine, HMB, and protein, ideal for building lean mass and power.

Should I take these supplements on rest days?

Yes — recovery and muscle growth continue outside the gym. Taking your protein and creatine consistently helps maximise your results.
