Picture a trainee standing in the supplement aisle with a list from an influencer in one hand and a credit card in the other. Twelve tubs, three pill bottles, two "stacks," and a "designed by" celebrity blend. Roughly £200 a month. Imagine the version of that trainee who walks out with creatine, whey, vitamin D, and a coffee habit, for around £25 a month, and gets the same training outcomes.
That is the entire field guide.
