As you’re in the Netherlands, how about Fuegenix ? I just mentioned them in another thread. They are doing some really good work. We have quite a few results here on the forum.
HDC might be another option (Cyprus), hit @Doron Haratiup, he’s the rep, they are also forum recommended. Dr Christina is around €2 per graft.
You also have some choices in Belgium, Dr Bisanga, Dr Mwamba, Dr Lapunzula + Dr Feriduni. Again plenty of forum results and these are mostly forum recommended.
