Forgive me if this has been covered somewhere else but…
Im having a tough time lining up our in house potency testing results with 3rd party testers.
I operate the HPLC here and I seem to get consistently higher results than when we send them out for verification.
Our only fix seems to be to try and formulate 10% higher and cross our fingers.
I know that theres production issues in house and variances there but…
What is everyone elses experiences and what do you do to combat it?
