I'm not suggesting you are using excipients carelessly. I'm simply asking, or suggesting, that you consider a "nanoparticle free" product line. It's a business tip. Maybe no one else here would care, but eventually someone will make a "nanoparticles free" brand. Maybe you should be the first.
I understand the attitude of "fuck, these nanoparticles are in everything, so what difference does it make if there are some in a few oral steroids? People are exposed to way more of these materials outside of what they would consume from me."
I'm just saying, let's not dismiss the dangers of these nanoparticles. For some, it's an acceptable risk and that's fine. For others who want to reduce their exposure, they shouldn't be met with criticism.
