Peptide therapy at Greenwich MD is not a one-size-fits-all protocol. Dr. Querido tailors every plan to the patient based on goals, labs, and clinical evaluation. Below are the three main categories of peptide protocols we offer.
This category of peptides supports tissue healing, gut repair, and inflammation modulation. They are commonly used by patients recovering from injury, surgery, or intense training.
Peptides commonly used:
Typical patients: athletes, post-surgical recovery, GI healing, chronic inflammation.
This category supports natural growth hormone production through stimulation rather than direct hormone replacement. Patients often use these for sleep quality, recovery, body composition, and longevity goals.
Peptides commonly used:
Typical patients: longevity-focused adults, those addressing age-related decline in recovery and sleep.
This category includes peptides and related compounds that support immune function, cellular energy, and metabolic regulation.
Peptides and related compounds commonly used:
Typical patients: immune support during recovery, metabolic health, supervised weight management.

Therapeutic peptides prescribed by a licensed physician and sourced through US-licensed compounding pharmacies are legal. The legal landscape around specific peptides changes periodically. Dr. Querido stays current on FDA guidance and prescribes only peptides that are clinically appropriate and available through legitimate pharmacy channels.
Most patients notice changes in sleep quality, energy, or recovery within 3 to 6 weeks. Body composition changes, hormonal markers, and longevity-related effects are typically reviewed at 3 and 6 month intervals.
Peptides used in physician-supervised protocols, with pharmacy-grade sourcing and appropriate monitoring, have a strong safety profile. Risks rise sharply when peptides are obtained from non-pharmacy sources or used without medical oversight, which is why supervision matters.
Peptide therapy is generally not covered by insurance, since it is typically pursued for wellness or longevity goals rather than treatment of a diagnosed condition. Lab work associated with the protocol is sometimes covered. We will help you understand what is covered before you start.
Most protocols involve daily or several-times-weekly subcutaneous injections, which patients self-administer at home using small insulin-style needles. We teach you the technique at your first visit. The injections are well-tolerated and quick.
