No similarities. I have concentree and its very woody, i would say pine and vetiver that makes me remember polo especially if i wash my wrist with cold water only. It has a middle note vibe like bubble rubber which i love and dont know what the hell is that. It has many drydowns and on cold weathers are more resinous. I great scent and i wear even on summer because it stays more herbal. Anteus is related with santos regular... ahh here we have great similarities!! i compared then in my wrists some times. Anteus is more powdery, with a sour note and lasts more. Santos regular is more herbal, straight to, powdery but with none sour. The heart is the same.
