Do BPC-157 and TB-500 build muscle?

Neither has a published study in people that measured muscle growth. Both are studied and sold for repair and healing, not for building muscle size. The ways they are said to work, growing new blood vessels and helping cells move for BPC-157, and acting on a cell-shape protein (actin) for the TB-500 fragment, are about recovering from injury, not building muscle. Any muscle-building claim for either one goes beyond what their own research has measured.
