No compound is perfectly specific. Off-target effects can be beneficial (an anti-diabetes drug that also protects the heart, as seen with GLP-1 agonists) or adverse. Understanding off-target profiles requires systematic receptor binding studies and broad safety pharmacology. For research peptides, off-target effects are often unknown or understudied because comprehensive receptor panels aren't typically part of early preclinical work. This is a key limitation cited when discussing research peptides' overall safety and effect profiles.
