❝ ❝ Somewhere in the Bioequivalence guidance I remembered that when designing the studies we try to keep T/R potency +/-5%. Can someone point out where this kind of condition existed, (latest guidance has no mention of this)

❝

❝ – AFAIK, it was never stated by the FDA in any guidance.

It was there in 2001 guidance as desired requirement-not mandatory... problem is that I can not find that 2001 (first) BE/BA guidance
I can not find that 2001 (first) BE/BA guidance. Also in 2021 guidance lines 807-808
