Unfortunately that's only 12% methyl salicylate. The people I know/knew that use Bengay regularly only use the higher strength versions at 30% methyl salicylate.
That said, I do find the UK to be substantially better than the Netherlands for buying a lot of things, despite being only about a hundred miles away. I wish there was an easy way to get products from the UK to the Netherlands - that would make a lot of things easier. There's stuff like Borderlinx but the prices are very high for such a short distance.
