TitanACE-031
Myostatin trap. Muscle growth unlocked.

About
What it is
ACE-031 is a soluble activin receptor that acts as a myostatin trap — it captures myostatin before it can signal muscle cells to stop growing. A different approach to the same goal as follistatin.
How it works
ACE-031 is a soluble form of activin receptor type IIB. It circulates in the blood and captures myostatin and related ligands before they can bind to muscle cell receptors, effectively blocking the 'stop growing' signal.
