Read the scope, not just the name.

Every approval above covers a specific indication. Tesamorelin is approved for one HIV-related indication and is weight-neutral. Elamipretide is approved for one rare disease. An approval for one indication is not evidence for another.

Sermorelin is a special case.

It held an FDA approval as a diagnostic agent from 1997. The approval ended in 2008 for commercial reasons, not because of a safety finding. Read the Sermorelin profile.
