Prescription peptides, recommended only when your history and lab work support them.
Peptide therapy starts with a consultation with Cynthia Diaz, FNP-C, and lab work at our Tucson office. A peptide is prescribed only if your history and results support it, with regular check-ins to review how it’s going.
Visits are at our Tucson office. We don’t bill insurance.

Peptides are short chains of amino acids, the same building blocks that make up proteins. Your body makes many of its own, and some peptides are also made into prescription medications.
Some peptide medications are FDA approved for specific conditions. Others are made by compounding pharmacies, and compounded drugs aren’t FDA approved, which means the FDA hasn’t reviewed their safety, effectiveness or quality before they’re sold. The evidence behind each peptide varies too, so we look at each one on its own.

Some peptide medications are FDA approved for specific conditions. Others are made by compounding pharmacies.
The federal rules on which peptides pharmacies can compound are under review, and some currently can’t be lawfully compounded. We only prescribe peptides that can be lawfully prescribed and prepared.
Peptides sold online as “research use only” are labeled for laboratory research and aren't meant for people.
If you’ve been using a peptide from an online seller, tell us at your consultation so we can take it into account.
Side effects depend on the peptide, the dose and the person.
Tell us about every medication and supplement you take, since some can interact.
A consultation doesn’t guarantee a prescription. We recommend a peptide only when your history and labs support it, and results vary from person to person.

Peptide therapy is treatment with a prescribed peptide, a short chain of amino acids. Some peptide medications are FDA approved for specific conditions, and others are made by compounding pharmacies. At our office, it starts with a consultation and lab work, and a peptide is prescribed only if your history and results support it.
We don’t list specific peptides here because the right option, if there is one, depends on your health history, lab results and goals. We’ll go over what may fit you at your consultation.
Some are. Certain peptide medications are FDA approved for specific conditions. Compounded peptides aren’t FDA approved, which means the FDA hasn’t reviewed their safety, effectiveness or quality before they’re sold. We’ll tell you which kind you’d be prescribed and why.
Yes. Bloodwork comes before any peptide plan, so the decision is based on your results as well as your history.
Not necessarily. A peptide is prescribed only after your consultation and lab results show it’s appropriate. Sometimes the better answer is a different option or no treatment.
It depends on the peptide. If one is prescribed, your plan explains how and when to take it, which side effects to watch for and when to call us.
