Holdup is there's no controlled and monitor animal demo of efficacy and safety. They go hand in hand and can't be separated. At clinical doses and even injection distribution of Radiogel throughout tumor, the injection pressures and number of injections are higher than at less than clinical doses that don't completely kill tumor. So one has to do the former to make any valid containment conclusions. Hence why FDA rejected everything RDGL has presented to date. It was fraudulent junk science at its finest.
It all comes down to what happened to the second set of rabbits in 2023 and what is MK hiding? Occam says Radiogel leaked all over the place at clinical doses.
By all appearances Radiogel is dangerous snake oil and RDGL is a scam
