Peptides & Hormones. What they are. What they're not.

What is a peptide?

A peptide is a short chain of amino acids — typically anywhere from two to fifty linked together. Amino acids are the building blocks of proteins; peptides are smaller signaling units assembled from them. Your body makes peptides constantly. Many of the messengers that run your metabolism, repair systems, sleep cycles, and hormone signaling pathways are peptides.

Insulin is a peptide. Oxytocin is a peptide. Glucagon is a peptide. Growth hormone is a peptide. Sermorelin, melanotan, BPC-157, semaglutide — all peptides. The category covers a wide range, from naturally occurring molecules in your body to synthetic analogs designed to mimic, augment, or block specific biological signals.

In therapeutic medicine, peptides are sometimes administered to support, modulate, or restore a specific physiological function. Done correctly, that means a licensed provider, a clinical evaluation, a documented rationale, lab-based decisions, and ongoing monitoring. Done incorrectly, it means buying powder off a website and hoping for the best — which is not what we do here.

What is a hormone?

A hormone is a chemical messenger produced by your endocrine system — glands like the pituitary, thyroid, adrenal, and gonads — that travels through the bloodstream to regulate functions across the body. Hormones govern growth, metabolism, mood, sleep, sexual function, immune response, stress adaptation, and most other systems that matter.

Some hormones are themselves peptides (insulin, growth hormone, oxytocin). Others are steroid hormones derived from cholesterol — testosterone, estrogen, cortisol. There are also amino acid-derived hormones like thyroid hormone and adrenaline. The category "hormone" is broader than "peptide," but the two heavily overlap.

What they're not.

Peptide and hormone therapy has been over-marketed for decades — first by black-market gym culture, more recently by social media wellness accounts and online clinics happy to sell hope. We're going to be specific about what these therapies are not.

What is a 503A compounding pharmacy?

A 503A compounding pharmacy is a state-licensed pharmacy that compounds — meaning prepares, mixes, or alters — medications for individual patients pursuant to a specific prescription from a licensed prescriber. The "503A" name comes from Section 503A of the Federal Food, Drug, and Cosmetic Act.

Key things about 503A pharmacies:

• Each medication is prepared for a named patient with a valid prescription
• They are licensed and regulated by state boards of pharmacy
• They cannot mass-produce or stockpile finished drug products for general distribution
• They must comply with USP standards (USP 795 for non-sterile, USP 797 for sterile, USP 800 for hazardous compounding)
• They are not subject to FDA Current Good Manufacturing Practices (cGMP) the way commercial drug manufacturers are

This is the model that allows for individualized peptide and hormone therapy. Your provider writes a prescription specific to you. The 503A pharmacy compounds your medication specifically for you. It ships to you specifically.

What is a 503B outsourcing facility?

A 503B "outsourcing facility" is a different category of compounder. 503B facilities register directly with the FDA, submit to FDA inspections, and operate under current Good Manufacturing Practices — the same cGMP standards that govern commercial drug manufacturing.

Key things about 503B facilities:

• They can compound medications in larger batches for "office use" — meaning clinics can stock 503B-compounded medications on-site without a patient-specific Rx for each unit
• They are inspected by the FDA
• They must report adverse events to the FDA
• They follow cGMP — a higher regulatory bar than 503A
• They cost more to produce, generally, but offer additional oversight

FDA status — being honest about it.

The FDA regulates drug approval through a specific process: preclinical research, clinical trials, New Drug Application review, and post-market surveillance. When a drug is "FDA-approved" for a specific indication, the FDA has reviewed evidence and authorized its marketing for that use.

Many peptides used in integrative medicine — including some discussed at Cowboy Health — are not FDA-approved for the specific indications under consideration. This doesn't make them illegal; the compounding framework above, combined with state board oversight and a provider's prescription, creates a legal structure for their use. But it does mean specific honest disclosures must be made:

• We cannot and do not claim peptide therapies are FDA-approved treatments for illnesses for which they don't have approval
• We cannot and do not promise specific outcomes
• Many peptides are used "off-label" or under compounding exemptions; your provider will tell you the status before you decide
• The FDA's regulatory posture toward specific peptides has changed and continues to evolve. In recent years, several peptides (including BPC-157, CJC-1295, ipamorelin, and others) have been moved between bulk substances lists, affecting compounding availability

Our framework — integrative, functional, intelligent.

Cowboy Health practices integrative and functional medicine. It's not a substitute for conventional medicine — it's a framework that combines conventional, evidence-based care with other appropriate approaches when the clinical picture warrants it. Some characteristics of how we work:

• We treat the patient, not just the lab number. A testosterone level inside the "normal" range may still represent meaningful dysfunction for that individual; that's a clinical conversation, not just a reference range
• We start with the basics. Sleep, nutrition, stress, movement, alcohol, and metabolic health are addressed first. Peptides and hormones are tools, not foundations
• We document the rationale. Every therapy starts with a documented reason, an expected outcome, and a plan to evaluate whether it's working
• We disclose what we don't know. Where the evidence base is thin, where regulation is in flux, where individual response varies — we tell you
• We don't sell hope. If a therapy isn't appropriate for you, isn't likely to help, or isn't worth the cost, we say so

"Intelligent medicine" is the shorthand we use internally: thoughtful, individualized, willing to combine modalities, willing to tell you the truth.

Provider order. Prescription required.

To make this completely unambiguous: every peptide and hormone therapy provided through Cowboy Health requires the following before anything is administered or shipped.

• An established patient-provider relationship at Cowboy Health
• A clinical evaluation by a licensed provider
• A documented order from that provider
• A prescription, where applicable
• Sourcing exclusively from a licensed 503A or 503B compounding pharmacy

We do not mail medications without a prescription. We do not administer therapies without a provider order. We do not work with unlicensed sources, research-chemical retailers, or grey-market suppliers. Patients who arrive expecting otherwise are referred elsewhere.
