Italian brand 4+ Nutrition has released another clue for its next new supplement, that was recently confirmed to be featuring Hydro C95 hydrolyzed protein. The brand has now revealed that the still unnamed product is going to be featuring an unknown amount of citrulline. 4+ Nutrition has also mentioned that this is just another one of the mystery supplement’s features, suggesting there is quite a few more to be named. While it is most likely a good thing that the brand has put a lot into the product, the downside is that we’re only seeing one ingredient every three days so the unveiling may take some time.
