Physician-Led Peptide Evaluation
Peptide Therapy in Los Angeles & Beverly Hills
Peptides are a broad class of signaling molecules and medicines—not one treatment. At our Los Angeles and Beverly Hills hormone clinic, evaluation starts with your symptoms, medical history, goals, medications and clinically appropriate testing before any peptide or hormone treatment is considered.

Peptide Guide
Explore Peptide Therapy Topics
These guides explain what is known, what remains uncertain, regulatory considerations and when a medical or endocrine evaluation may be more appropriate.
Thymosin Beta-4 / TB-500
Research context, proposed uses and the limits of current human evidence.
Peptides for Muscle Growth
Evidence, risks and established alternatives for muscle and body-composition concerns.
Peptides for Skin
Topical versus injectable peptides and what evidence supports for skin-related goals.
GHK-Cu
Copper peptides, route-specific evidence and injectable safety considerations.
IGF-1 & Growth Hormone
When endocrine testing is appropriate and how true growth-hormone disorders are evaluated.
Start With the Diagnosis
Peptide Therapy Is Not the Same as Hormone Replacement
Peptides are short chains of amino acids that can act as signaling molecules. Steroid hormones have a different chemical structure and mechanism, and hormone replacement is intended to replace or treat a clinically established hormone problem. Symptoms such as fatigue, poor recovery, low libido, sleep disturbance, reduced muscle mass or weight change can have many causes.

Medical Evaluation
How We Evaluate Peptide and Hormone Concerns
Consultation
Symptoms & Goals
Review symptoms, goals, medical history, medications and prior treatments.
Testing
Targeted Evaluation
Laboratory testing or other evaluation is selected when clinically appropriate—not as a one-size-fits-all panel.
Decision
Evidence & Options
We compare established treatments, regulatory status, evidence, uncertainties and potential risks.
Follow-Up
Monitoring
When treatment is appropriate, follow-up is individualized to the therapy, diagnosis and patient response.
Peptide Therapy FAQ
What is peptide therapy?
“Peptide therapy” is an umbrella term. Peptides include naturally occurring signaling molecules, approved peptide-based medications and experimental or unapproved compounds. The exact compound, indication, route and evidence matter.
Are peptides the same as steroids?
No. Peptides and steroid hormones are chemically and biologically different classes of molecules.
Can peptides replace hormone replacement therapy?
Not generally. Treating a documented hormone disorder and using a compound that modifies a signaling pathway are different clinical decisions.
Are CJC-1295 and ipamorelin FDA-approved for anti-aging or body composition?
No. These compounds should not be presented as FDA-approved anti-aging or body-composition therapies. Their regulatory and compounding status requires careful review, and available clinical data are limited.
Should laboratory testing come before peptide treatment?
When symptoms could reflect an endocrine, metabolic or other medical condition, evaluation should identify the likely cause and guide treatment rather than starting with a predetermined peptide.
Do you offer peptide evaluation in Beverly Hills and Los Angeles?
Yes. Our practice evaluates patients in the Los Angeles and Beverly Hills area. Recommendations depend on the individual diagnosis, evidence, safety and current regulatory considerations.
Physician-Led Peptide & Hormone Evaluation
If you are considering peptide therapy, start with a medical evaluation focused on the underlying concern—not a preselected compound. We can review your symptoms, prior treatment, laboratory data and appropriate options.
