Read the evidence
In an older-adult trial, increased fat-free mass did not translate into improved strength or function; glucose and insulin sensitivity also changed.
Resolve the identity
This is a small molecule, so a peptide residue count is not applicable. Distinguish ibutamoren from its salt forms.
