hi dr bob i got from the factory :certificate of analysis containing:colorodorappearanceph i want to do microbial and stability its written here microbiology:<1,000 cfug or ml-not requested meaning they didnt do it

NO Looks like they did not: ask why they didn’t do preservation USP 51 as needed by your company prior to marketing.Also they should do viscosity.Are temperature and Time listed on certificate?

they recommend to do a stability test through a 3rd party on the final product{i get it as a bulk}no viscosity and no temperature or time just date and sign i approach them saying something dont look right to me there is lack of information i also sent some files showing what u get in terms of info from another manufacture for them to understand what dosnt look good in my eyes
