Questions
Does THE FOCUX give dosing advice?
No. We describe what studies measured and what EU law allows to be said. We do not recommend amounts.
Which of these have authorised EU health claims?
Of the five on this page, only creatine. Its two authorised claims are quoted word for word, under the conditions of use set by the Regulations.
Why are there no buy buttons here?
Evidence comes first. Any future affiliate slot appears only on an individual compound page, after the evidence, clearly labelled as advertising.
