I would think even 95%, remember the alternative is seeds that migrate and can (and do) cause circulation issues.
I just do not understand the FDA delays since the seed products are still approved for use, even with their poor record of side effects. Maybe they should request additional seed tests and revisit those approvals since the results were obviously incorrect or not properly documented.
Very glad they are developing Isopet in the mean time. I doubt they are letting its development supersede or delay ANY Radiogel progress, and this is happening in the background.
