The evidence scale

Every recommendation we make is backed by science.

From rock-solid meta-analyses to marketing myths — you'll always know which is which.

Evidence A

Protein intake of 1.6–2.2 g/kg supports muscle growth

Backed by multiple meta-analyses of resistance-training studies.

Evidence B

Creatine monohydrate improves strength output

Consistent RCT evidence; small variance in response between individuals.

Evidence C

Meal timing has a modest effect on hypertrophy

Mixed findings; total daily intake matters far more.

Evidence D

Detox teas accelerate fat loss

No credible evidence. Marketing claim only.
