Busou Renkin, Fullmetal Alchemist: Brotherhood Recommendations
The series are actually very different. In comparison to FMA, in Busou Renkin you can actually bring dead to life.
However, both series use Alchemy as a fighting power and their enemies are homonculus. So if you simply want to see different version of Alchemy, feel free to check any of those shows.
Both deal with alchemy and fighting humunculi. Decent story lines as well with memorable characters.
Busou Renkin and Fullmetal Alchemist Brotherhood focus on the concepts of alchemy and the creation of homunculus. They contain a similar flow of action, comedy, and romantic conclusions.
