No matter your goal, we've got a stack to suit you! Wanting to put on some muscle? Keep reading.

The F45 Challenge Muscle Gain Stack contains:

To optimise your muscle gain results, we recommend the following:

  • 1 scoop of C4 Pre Workout 15 minutes before training
  • 5g of creatine every day (can be mixed with anything and taken at any time)
  • 1 scoop of protein post-training

Why these products?

C4 Pre Workout helps you turn your ambitions into achievements. It is the perfect pre-workout formula - bringing you energy, endurance, focus, and pumps. It'll help you train harder and make the most out of every session.

Creatine increases the body's ability to produce energy rapidly. It helps you to lift more weight and for longer, which enables you to build more muscle. Creatine needs to be built up over time so it is most beneficial to take 5g every day, regardless of whether or not you are training. It will also help you recover faster with time.

Protein is the most important nutrient for building lean muscle as it is the building block of your muscles. The amino acids in protein are essential in repairing and maintaining muscle tissue. Many people struggle to consume an adequate amount of protein through meals alone so consuming a shake after working out can help to supplement this. A high protein diet also helps to boost your metabolism and increase fat burning, meaning your body will prioritise gaining muscle when eating in a calorie surplus.
