U.S. regulatory status

How it works · Peptide signaling
Amino acids, linked
A peptide is a short chain of amino acids, usually 2 to 50 long. Your body makes thousands of them to carry messages.

Animations simplify biology for teaching. They are not a claim that this peptide works this way in people.

What the research shows

Early small studies were exciting. Larger randomized trials have mostly not confirmed benefit.

Safety and considerations

Intranasal use is generally well tolerated. Not for use in pregnancy outside obstetric care.

Our position

Grade C, with clear expectation-setting before anyone starts.
