How does Peptide Therapy actually work?
Peptides are short protein fragments that act as signalling molecules, binding receptors to influence growth hormone release, inflammation, appetite, or tissue repair. The category is extremely broad, and that breadth is the important point: a few peptides have FDA approval and solid trial data, while many marketed in wellness settings rest on animal studies, small trials, or mechanistic reasoning alone. The right question is never 'do peptides work' but 'what evidence exists for this specific peptide, at this dose, for my goal'.
Who is a good candidate for Peptide Therapy?
Adults with a specific goal, willing to have labs drawn and reviewed, and comfortable with the evidence being weaker than for established medications.
Who should skip it?
Anyone with an active or prior malignancy, given growth-signalling concerns; anyone pregnant or breastfeeding; anyone unwilling to have baseline labs; and competitive athletes subject to anti-doping rules, since many peptides are banned.
Who should be performing it?
A prescribing clinician (MD, DO, NP, or PA) who reviews labs, history, and medications before writing the prescription.
