> e.g. acetone plus hydrogen peroxide yields APEX/TATP

TIL, didn't know that. Acetone is right next to peroxide in the local household items store (in the Netherlands) over here. But a few aisles over you can also find CBD oil and melatonin, heavy duty painkillers like diclofenac, etc.

These are available here as well, but the concentrations (especially of the hydrogen peroxide) are far too low to be useful in bombmaking or most classic experiments involving it, and on top of that dilution from the factory, it's likely a bunch of the peroxide dissociated since it was manufactured. You need to concentrate the hydrogen peroxide up to be useful for more than cleaning blood stains, and that's pretty dangerous.
