The Rodipet Syrian mix is good and it's organic
And the website is now in English as well
Are the ingredients ok on there for you? If not then Tiny Friends Harry Hamster is probably a safe bet. It contains all the nutrients and vitamins needed, has the right level of protein and the pieces are bigger less itty bitts etc. It contains whole peanuts in their shells but you said you were ok with nuts. The Rodipet one is slightly low on the protein side but it would be easy to supplement with the odd fresh extra like a nut twice a week, and mealworms or freeze dried chicken.
This is the Rodipet one. They do two Syrian organic mixes, one for junior hamsters under 1 year old, and another for senior hamsters over a year old. However I have kept with the junior mix for our older syrian - he didn't like the senior one and it seemed a bit bitty.

With postage it makes it more expensive, so I get two at a time to save on postage.
Otherwise you can't go wrong with Harry Hamster as a basic diet with everything that is needed, and it's sugar-free and hamsters seem to like it and eat all of it.
