What Is Peptide Therapy?
Peptide therapy uses short chains of amino acids — naturally occurring signaling molecules — to target specific biological processes in the body. Unlike broad-spectrum pharmaceuticals, peptides communicate directly with cells to stimulate healing, optimize hormonal balance, reduce inflammation, and accelerate recovery.
At Live Now Longevity in Las Vegas, Dr. Charles Kamen, MD brings a neurologist's precision to peptide therapy. With advanced training from Albert Einstein College of Medicine and Yale-New Haven Hospital, Dr. Kamen designs individualized peptide protocols based on lab work, clinical history, and measurable outcomes — not trends or guesswork.
Every protocol at Live Now Longevity follows an evidence-based framework. You receive direct physician oversight from consultation through follow-up, with dosing adjusted based on your response and lab markers. This is concierge-level care: no rushed appointments, no mid-level handoffs.
Peptides We Offer at Live Now Longevity
Dr. Kamen selects from a curated formulary of research-backed peptides, sourced exclusively from FDA-registered 503B compounding pharmacies.
BPC-157 (Body Protection Compound)
Primary use: Tissue repair, gut healing, injury recovery
BPC-157 is a gastric pentadecapeptide that accelerates wound healing, supports tendon and ligament repair, and promotes angiogenesis. It is commonly used for sports injuries, post-surgical recovery, and gastrointestinal conditions including leaky gut. Research shows BPC-157 modulates the nitric oxide system and the FAK-paxillin pathway critical to tissue remodeling.
CJC-1295 / Ipamorelin
Primary use: Growth hormone optimization, body composition, recovery
This combination stimulates your pituitary gland to produce more growth hormone naturally. CJC-1295 extends the half-life of GHRH, while Ipamorelin acts as a selective growth hormone secretagogue. Together, they improve lean muscle mass, reduce body fat, enhance sleep quality, and support faster recovery while maintaining natural pulsatile GH release.
PT-141 (Bremelanotide)
Primary use: Sexual health and libido enhancement
PT-141 is an FDA-approved peptide that works through the melanocortin receptor system to improve sexual desire and arousal. Unlike PDE5 inhibitors that act on blood flow alone, PT-141 addresses desire at a neurological level, effective for both men and women.
Thymosin Alpha-1
Primary use: Immune modulation and resilience
Thymosin Alpha-1 enhances immune surveillance by stimulating T-cell maturation and natural killer cell activity. Used for chronic infections, autoimmune conditions, or immunodeficiency, it is approved as a pharmaceutical in over 35 countries.
Semaglutide / Tirzepatide
Primary use: Medical weight management
These GLP-1 receptor agonists regulate appetite, blood sugar, and metabolic function with 15-20% body weight reduction in clinical trials. Prescribed as part of a comprehensive metabolic optimization program with regular lab monitoring and nutritional guidance.
NAD+ Peptide Support
Primary use: Cellular energy, neuroprotection, anti-aging
NAD+ is essential for mitochondrial function, DNA repair, and sirtuin activation. Our NAD+ protocols — via IV infusion or subcutaneous injection — restore declining levels to support cognitive clarity, physical endurance, and healthy aging at the cellular level.
Who Is a Candidate for Peptide Therapy?
Peptide therapy is appropriate for adults experiencing health concerns that have not responded to conventional treatments, or for those seeking proactive optimization:
- Athletes and active adults recovering from injuries or seeking faster recovery
- Adults over 35 with declining energy, poor sleep, weight gain, or reduced performance
- Patients with chronic inflammation including joint pain, gut issues, or autoimmune conditions
- Men and women with hormonal imbalances affecting libido, mood, or body composition
- Anyone pursuing longevity medicine who wants to optimize cellular health
- Post-surgical patients looking to accelerate tissue healing
During your initial consultation, Dr. Kamen reviews comprehensive lab work, medical history, and your specific goals to determine which peptides will deliver the best results.
What to Expect During Treatment
Step 1: Comprehensive Consultation
Your first visit includes a detailed health history review, physical assessment, and comprehensive lab panel. Dr. Kamen personally conducts every consultation — you will never be seen by a mid-level provider. This initial visit typically lasts 45-60 minutes.
Step 2: Custom Protocol Design
Based on lab results and clinical assessment, Dr. Kamen designs a personalized peptide protocol including specific peptides, dosing schedules, administration routes, and expected timelines. You receive clear instructions and training on self-administration.
Step 3: Ongoing Monitoring
Dr. Kamen schedules follow-up labs at 6-8 week intervals to track biomarker response. Dosing is adjusted based on objective data. This iterative approach ensures optimal results while maintaining safety.
Step 4: Protocol Optimization
As your body responds, protocols evolve. Some peptides are cycled to prevent receptor desensitization. Others are adjusted based on seasonal needs or evolving goals. Live Now Longevity patients receive ongoing access to Dr. Kamen for questions and adjustments.
Safety, Side Effects, and Medical Oversight
All peptides are sourced from FDA-registered 503B compounding pharmacies under direct physician supervision. Common side effects are mild and transient:
- Injection site redness or mild irritation (resolves within hours)
- Temporary water retention during the first week of growth hormone peptides
- Mild nausea with GLP-1 agonists (managed through gradual dose titration)
- Flushing with PT-141 (typically resolves within 30-60 minutes)
Serious adverse effects are rare when properly dosed and monitored. Dr. Kamen's neurology background provides additional expertise in monitoring neurological and systemic responses. All patients receive his direct cell phone number for urgent questions.

Frequently Asked Questions
Are peptides FDA-approved?
Some peptides are FDA-approved for specific indications (e.g., semaglutide for weight management, PT-141 for sexual dysfunction). Others are used off-label based on published research. All peptides at Live Now Longevity are sourced from FDA-registered 503B compounding pharmacies meeting strict quality standards.
How are peptides administered?
Most peptides are administered via subcutaneous injection using a small insulin-style needle. Some are available as oral capsules or nasal sprays. Self-injection training is provided during your first visit.
How quickly will I see results?
BPC-157 for injury repair often shows improvement within 2-4 weeks. Growth hormone peptides typically produce noticeable sleep improvements within 1-2 weeks, with body composition changes at 8-12 weeks. Weight management peptides show progressive results over 3-6 months.
Can I combine peptide therapy with other treatments?
Yes. Peptide therapy integrates well with NAD+ infusions, IV therapy, and hormone optimization. Dr. Kamen designs comprehensive protocols combining multiple therapies for synergistic results.
Is peptide therapy covered by insurance?
Live Now Longevity is a cash-pay practice. We do not bill insurance directly. This model allows personalized care without insurance-mandated protocol restrictions.
Do I need a referral to start?
