If I have multiple strength of pharmaceutical finished product and I am doing Bioequivalence study on higher strength one batch, then for rest of the strengths , when I need to test reference samples testing, is it mandatory to test them on GMP facilities or testing in R&D facility is sufficient?

For Reference sample used for BE will be surely tested at GMP facility but what about other strengths of RLD for which we are applying for waiver against Bio strength?
