Why this certification matters
- Informed Sport
- Informed Sport certification is especially relevant for athletes in tested sports because products are batch-tested for substances prohibited in sport.
Frequently asked questions
- What is a mass gainer?
- A high-calorie powder that combines protein with a larger dose of carbohydrates, aimed at people who struggle to eat enough to gain weight. Critical Mass Professional is the gainer in Applied Nutrition's range.
- Where is it cheapest?
- It is listed at £69.95 at all three retailers we track — Amazon UK, Applied Nutrition direct and Holland & Barrett — so price is not the deciding factor. Choose on delivery cost, loyalty points or availability.
- Is it tested for banned substances?
- Yes. Critical Mass Professional carries Informed Sport, with every batch independently screened against the WADA banned-substances list.
- Should I use a gainer or a standard whey?
- A gainer suits hard gainers who need extra calories; if you mainly want protein without the added carbohydrate load, a standard whey such as Applied Nutrition's Critical Whey is the better fit.
