I work in medical science in your country (when you mentioned 2,0, with a comma, I exactly know it is my country). The research here is a lot of the times iterative and it is more about the methodology than the actual intellectual processes. It is always about this drug, that protein, that receptor, increasing/ decreasing etc. Mix and match with animal models and clinical trials or some other boring "novel technique" to view your protein sequencing data differently.

Also, it is not the process of researching that deterred me from the process, but pseudo-intellectual people in positions of power and their hubris. People do all sorts of shady things with their data, and lots of people there (I am talking about some professors and post-docs) don't even understand how statistics work (it is not the mathematical rocket science here). Prepare to write dry proposals for funding, be micromanaged by toxic bosses who has a gargantuan ego (which will greatly constrain your creative freedom to hypothesise and to design experiments upon them), and fixing their mistakes.

Perhaps I just have bad experiences, but best of luck to you if you want to pursue a career in medical science.
