Sure, so you could say they labelled theirs correctly and those that are labelling it 5%(I2 content) are wrong since they are the same solutions
All quite confusing to newcomers who should check exactly what the formulation is
In the UK Lugols is called aqueous Iodine oral solution and is always 5% Iodine and 10% KI as you say
The problem is of course that they are selling lots of concentrations and calling them all lugols, which I found confusing myself at first when reading this forum
