Peptides at Griffin: What They Are, What They Do, and How to Access Them
Peptides are getting a lot of attention right now. Some of it is grounded in decades of clinical use. Some of it is moving faster than the evidence. Here is how to tell the difference.
If you have spent any time reading about health and longevity recently, you have probably come across peptides. They are showing up in podcasts, supplement ads, biohacking forums, and increasingly in conversations with your physician. The interest is real, but the information landscape is messy. Some peptide therapies have decades of clinical evidence behind them. Others are genuinely promising but still being studied. And some are being sold through unregulated channels with no quality controls at all.
At Griffin Concierge Medical, peptide therapy is something we prescribe when the clinical picture supports it, through our compounding pharmacy partnership, with physician oversight and lab monitoring. This article covers what peptides actually are, which ones we use and why, what the regulatory landscape looks like right now, and how Griffin members can access them.
What Are Peptides, in Plain Terms?
Peptides are short chains of amino acids - the same building blocks that make up proteins. Your body produces thousands of them naturally. They act as signaling molecules, telling different systems in your body what to do: speed up tissue repair, modulate your immune response, regulate your metabolism, reduce inflammation, or trigger the release of other hormones.
What makes peptides useful in medicine is that they work with your body's existing biology rather than overriding it. They bind to specific receptors and influence targeted processes. This is not a new concept. Some of the most widely used medications in the world are peptide-based: insulin (used since 1921), oxytocin, calcitonin, and the GLP-1 receptor agonists like semaglutide that have transformed weight management and metabolic health.
What has changed recently is the breadth of research. Peptides are now being studied for applications in gut healing, tissue repair, immune modulation, cognitive support, and longevity - areas that were not on the clinical radar even a decade ago.
Which Peptides and Advanced Therapies Does Griffin Use?
We do not prescribe therapies because they are trending. We prescribe them when there is a clinical rationale backed by evidence, when the therapy is available through a regulated compounding pharmacy or established pharmaceutical channel, and when we can monitor the results. Here are the peptide and advanced therapies our physicians most commonly use:
| Therapy | What It Does | Common Use at Griffin |
|---|---|---|
| GLP-1 Receptor Agonists (semaglutide, tirzepatide) |
Regulate appetite, improve insulin sensitivity, reduce inflammation | Medical weight management, metabolic optimization, cardiovascular risk reduction |
| BPC-157 | Supports tissue repair, gut healing, and recovery from injury | Gut health restoration, musculoskeletal recovery, post-surgical healing support |
| Sermorelin / Ipamorelin | Stimulate natural growth hormone release, support IGF-1 optimization | Sleep quality, recovery, lean mass preservation, body composition |
| Low-Dose Naltrexone (LDN) | Modulates immune function and reduces chronic inflammatory signaling | Chronic inflammation, autoimmune conditions, immune dysregulation |
| Thymosin Peptides | Support immune system function and modulation | Immune support, recovery from illness, patients with compromised immune function |
| NAD+ Therapy (IV, oral NMN/NR) |
Supports mitochondrial energy production and cellular repair | Cellular longevity, energy optimization, cognitive support, recovery |
| Glutathione (IV, sublingual, liposomal) |
Master antioxidant supporting detoxification and immune function | Detoxification support, immune resilience, oxidative stress reduction |
| Hormone Replacement Therapy (customized per patient) |
Restores hormonal balance through bioidentical, compounded formulations | Longevity optimization, metabolic support, body composition, cognitive function |
| PCSK9 Inhibitors | Lower LDL cholesterol beyond what statins achieve alone | Cardiovascular risk reduction in patients with inflammation-driven lipid concerns |
Every peptide prescription is based on your lab work, symptoms, and health goals. Your physician determines what is appropriate, writes the prescription, and has it compounded through our pharmacy partner to pharmaceutical-grade standards. We then monitor your response through follow-up labs and adjust as needed.
"The value of peptide therapy is in precision. When you have the right compound, the right dose, and a physician who understands how it fits into your overall health picture, the results speak for themselves. That is what makes physician-guided therapy so effective."
Dr. Radley Griffin, Griffin Concierge MedicalWhy Source and Quality Matter
This is the part of the peptide conversation that does not get enough attention. The same peptide can produce very different outcomes depending on where it comes from.
Peptides prescribed by a physician and compounded by a regulated pharmacy are prepared under strict quality controls: verified potency, pharmaceutical-grade ingredients, sterility testing, and proper storage. You know exactly what you are getting, at the exact dose your physician prescribed.
Peptides purchased online as "research chemicals" or through supplement retailers are a different story. They are not regulated for human use, not tested for purity or potency, and come without any clinical oversight. The quality gap between these two sources is significant, and it directly affects the results you can expect.
At Griffin, all peptide prescriptions go through our compounding pharmacy partner. We do not recommend sourcing peptides independently, and we encourage members to bring any peptides they are already taking to their physician for review.
The Regulatory Landscape Right Now
The FDA has been paying closer attention to peptides, particularly those used in compounding. In recent years, the agency has evaluated certain bulk substances used in compounding and categorized some as ineligible based on safety concerns. This regulatory environment is still evolving, and what is available today may shift as new guidance is issued.
What this means for you as a patient is straightforward: your Griffin physician stays current on which peptide therapies are available, which are under regulatory review, and which can be prescribed safely and legally through a compounding pharmacy. You do not need to navigate the regulatory landscape yourself. That is part of what we do.
How Griffin Members Access Peptide Therapy
The process is simple and starts with a conversation:
- Bring it up with your physician. Whether you are curious about a specific peptide or just wondering if peptide therapy could help with something you are experiencing, your next visit is the right time to ask.
- Your physician evaluates. Based on your symptoms, health goals, and lab work, your physician determines whether a peptide therapy is clinically appropriate and which one fits your situation.
- Prescription and compounding. If a peptide is prescribed, it is compounded through our pharmacy partner to pharmaceutical-grade standards, with the exact dose and formulation your physician specified.
- Monitoring and adjustment. Like all therapies at Griffin, peptide prescriptions include follow-up labs and check-ins to make sure the therapy is working and to adjust if needed.
You can also reach out to your patient care coordinator or use the Griffin app to start the conversation before your next visit.
