Peptide Therapy in Los Gatos
Aging shouldn’t mean losing energy, muscle, or focus. Yet for many people, slower recovery, subtle fatigue, and declining performance gradually become accepted as normal. Others feel generally well, but know they are not performing, recovering, or aging as optimally as they could.
Peptide therapy is increasingly used as a precision longevity tool for both restoring what has shifted and optimizing performance at a higher baseline.
At YNC, Dr. Young started prescribing peptides in 2004. Our approach is to first use advanced diagnostics to identify early metabolic, hormonal, and cellular changes even before symptoms are obvious.
With these insights, we design personalized peptide protocols that support tissue repair, hormonal balance, and cellular resilience, helping you recover faster, maintain strength and focus, and perform at your peak for the long term.

What are Peptide Injections?
Peptides are short chains of amino acids that act as signaling molecules in the body, guiding cells on how to function, repair, and adapt to stress. Different peptides target specific biological pathways, including tissue repair, muscle recovery, metabolic health, immune regulation, cognitive function, and longevity.
Interesting fact: the human body produces over 7,000 different peptides.
Over time, these signaling systems naturally become less efficient, even in people who otherwise feel well. Targeted peptide therapy can help re-engage specific pathways, supporting improvements in energy, recovery, metabolic resilience, and cognitive clarity.
At YNC, peptide selection is guided by your physiology, goals, and diagnostic data, rather than a one-size-fits-all protocol.
We are experts in the use of metabolic peptides such as GLP-1s. Originally developed to support insulin regulation, they are now widely used in weight management because they help regulate appetite, slow digestion, and improve metabolic efficiency.

How Peptide Therapy Works
Peptides are messengers that guide your cells to repair, regenerate, and optimize cellular function. Some peptides boost collagen for firmer, healthier skin, while others build muscle, support DNA repair, and neutralize oxidative stress.
There are even peptides that help with cognitive decline, memory, and focus issues. Hormone-focused peptides enhance tissue growth, metabolism, and brain signaling, so you have steadier energy, sharper focus, and reduced inflammation.
At YNC, we customize every protocol using your lab tests, VO2max, as well as other longevity metrics, all of which give us a map to your unique hormonal, metabolic, and cellular profile.
Using this information, we target the main cause of your health issues with clinically proven peptides to improve performance and long-term health.
Peptides We Offer
Our licensed doctors use precise diagnostics to create peptide programs that counter the processes behind aging, such as cellular repair, hormone balance, inflammation, and metabolic function.
Every plan is customized to support your longevity and optimize daily performance. The world of peptides and their availability is ever-changing. Please consult with us if you don’t see something you are looking for.

Can I Benefit From Peptides?
Peptides help slow the biological effects of aging. At YNC, we use validated peptide protocols to repair tissue, boost hormone balance, and strengthen cellular function.
These therapies target the systems that decline first as we age. Peptides can help with:
- Fatigue and brain fog that increase with age
- Slower recovery after exercise or injury
- Skin aging, wrinkles, and hair thinning
- Joint stiffness and declining bone density
- Age-related muscle loss
- Reduced immune function
By stimulating collagen production, enhancing muscle protein synthesis, and supporting antioxidant defense, peptide therapy slows age-related decline.
How Our Peptide Program Works
We combine advanced diagnostics, targeted therapies, and ongoing monitoring to help you maintain vitality and extend your health span.
Initial Consultation
We start with a consultation to review your health history, current lab results, and lifestyle. This helps us identify why your body may not be functioning and create a focused, evidence-based plan to improve your overall vitality.
For some peptide therapies, a consultation or blood work may be recommended to personalize your program, but it isn’t required for all treatments.
Advanced Diagnostic Testing
We use comprehensive testing to find underlying causes that limit performance and accelerate aging. These include:
- Hormonal Panels: We measure the hormone levels of cortisol, DHEA-S, estradiol, progesterone, SHBG, FSH, testosterone, prolactin, etc.
- Metabolism: VO2max & mitochondrial function, thyroid function, and insulin sensitivity help us understand how your body produces and uses energy.
- Immune and Inflammation Markers: ESR, cytokines, and autoimmune panels to detect chronic inflammation or immune imbalances that can impair recovery and longevity.
Personalized Treatment Plan
Using your test results, we create a tailored treatment plan combining peptide therapies and other advanced therapies like NAD therapy, IV therapy, and HBOT.
Your treatment roadmap includes follow-up schedules, and measurable milestones. Our licensed doctors make every adjustment using real data to improve your long-term health.
