Probably NOT.
Most of the time, the ingredient that makes a [US] supplement effective is taken out of the Australian and New Zealand version/s of the products and/or the formula is changed completely, because that ingredient is considered to be a 'prescription medicine', (i.e. yohimbine). You will also notice, that even if the formula is the ORIGINAL formula, that the labelling will be different, because there are much harsher standards and rules on what is 'allowed' to be said on a label (i.e. labels are not allowed to have dosage tables categorized by weight, as it is considered to be 'therapeutic'), even if it IS the same product (be careful to read the labels for ingredient profiles).
