I just have CYNOMEL by SANOFI - same dose as yours.
Mine come in French packaging, not a word written in English and if you try and contact the UK distributor for info about their product they refer you to your endo!
You can compare the ingredients to your Teva, assuming there was a patient information leaflet with it.
As for strength, some people found Grossman Cynomel to be stronger than other brands, some people didn't notice a difference, one of those things that's down to the individual.
