Sorry NGNG, I don't follow. Are you asking about ground/powdered naltrexone before it's compounded into LDN? (If that's what you're asking, I don't know personally, but someone else might.)
Mine don't.... just pure white powder. Now, whether that's because mine were made from 'bulk 'powder, and yours were ground up Naltrexone pills I don't know. Contact the pharmacy... they do make mistakes. One in England accidentally killed a little old lady.
