Everything is Connected
About.
From Within was established in 2025 by husband-and-wife team, Dr. Barry Sanchez and Amanda Cowan Sanchez. Locals of Santa Barbara, they share a love of nature, community and healthy living.
Inspired by the belief that everything is connected and health extends beyond the physical, they had a desire to create access to therapies that treat the root cause of dysfunction rather than symptoms alone. These therapies include:
As a client of From Within, you will receive individualized treatment protocols based on your physiological needs and desired goals. Lab testing will be ordered as needed along with recommendations for supplements and lifestyle modifications.
Your treatment with the providers at From Within is not intended to replace your Primary Care provider but rather to fill a gap that exists in conventional medicine today.

Who we are.
Barry Sanchez M.D.
As a Stanford trained bariatric surgeon with over 20 years in practice, I’ve come to realize that achieving optimal metabolic health involves far more than surgery alone and goes beyond the limitations of conventional medicine.
Everything in the body is connected, from the brain to the gut, exemplified by the “gut brain axis.” Ignoring one aspect or working in silos falls short of providing patients with the comprehensive care they deserve. Achieving homeostasis—a state of balance among all body systems—is the root of our being and requires hormonal optimization.
To address this, I’ve pursued advanced education in male and female hormonal optimization and peptide therapy to enhance cellular healing by supporting mitochondrial function, promoting longevity, and improving overall health.
I’ve also expanded my focus to include plasmalogens to further support patients, particularly those facing cognitive decline. My offerings reflect my commitment to helping individuals heal from within and achieve their healthiest, most functional lives.

Amanda Cowan Sanchez
Growing up I witnessed firsthand the devastating impact of chronic illness. Both of my parents passed away prematurely due to complications of diabetes and struggled with depression throughout their lives. Their experiences inspired me to embark on a lifelong journey to understand how to prevent and treat these conditions by addressing their root causes.
As a teenager, I was prescribed PPI’s for acid reflux which I remained on for about a decade. Later I developed severe food sensitivities without understanding their origins. With the help of a functional medicine practitioner, I began to uncover the profound connection between nutrition and healing. Through targeted nutritional strategies, I was able to address my gut health and reclaim my vitality.
In my 40’s I discovered peptide therapy while searching for relief from post-workout soreness that lasted for days. Peptides not only enhanced my recovery and stamina but significantly reduced inflammation and supported my gut. This powerful synergy of peptide therapy and functional nutrition profoundly changed my life, and I’m passionate about sharing these tools with others.
Today I combine peptide therapy and functional nutrition counseling to help my clients achieve their unique goals. Whether you are looking to lose weight, address nutritional deficiencies or optimize your overall well-being, I’m here to guide and support you on your journey to lasting health and vitality.

"I came to see Amanda at the age of 46, in perimenopause and struggling to accept the way I looked and felt.
I already had had a healthy lifestyle and diet but needed guidance to help me understand that what had worked for me in the past needed some adjusting. Enter this unicorn of a woman…Amanda! Her coaching and peptides are just magic! She helped me reduce the hundreds of dollars I was spending on over-the-counter vitamins and supplements, adjusted my diet (I actually needed to eat MORE) and started me on a tailored peptide protocol created especially for me.
When I say she nailed it, that is an understatement. I am feeling and looking so much better. My clothes all fit me again (hallelujah!), my skin is glowing, I have energy again and my self-esteem is restored! Grateful!"

“As a competitive athlete, recovery is everything. After struggling with injuries and slow healing, I turned to Dr. Barry Sanchez, Medical Director and co-founder of From Within, for peptide therapy—and it’s been a game-changer.
Within weeks, I noticed faster recovery, reduced pain, and better performance. My energy increased, my sleep improved, and I felt stronger during training and competition- for instance, I can do higher intensity without many recovery days in between. I have also not been “sick” for 2 years. I know the peptides have been the cause.
Dr. Sanchez’s expertise in peptides and personalized approach gave me the edge I needed—not just to recover, but to perform at my absolute best. He is not only knowledgeable - he’s kind and caters to everyone’s individual needs based on their fitness, age, and goals.
If you’re looking to optimize recovery, performance, and longevity, I highly recommend From Within and their peptide therapy program. Trust me- I’m living proof the peptides work!”

"I sought Amanda's guidance for a peptide protocol to address back/hip stiffness & soreness post-surgery on a ruptured disc.
I also was looking for skin healing and improvement after having several skin cancer lesions removed. She recommended a combination of BPC-157, GHK-CU & TB-500 for a period of 6-8 weeks. After completing the regimen, I can report some remarkable changes and improvements.
My taste and smell are back after being gone for 4 years! My hand tremors have greatly improved and my skin and hair show improvements, most notably my skin healed quickly from a cancer peel. I have to say my spine and hip aches have improved as well."

"Amanda suggested getting my hormone levels checked and referred me to Dr. Sanchez for labs. Dr. Sanchez started me on hormone replacement therapy, and I can’t believe how much better I feel in just a week! I fall asleep easily, my hot flashes are gone, and my mood has been more stable.
Feeling more like “me” than I have in a long time. I’m now working with Amanda to incorporate peptides and nutritional changes to improve my overall health and I’m already losing weight and moving more."

At the age of 65 I started working with Dr. Sanchez to improve my overall health and longevity. As you get older, life starts to get you down a little bit and there are a lot of aches and pains. Having a younger wife, I wanted to improve all aspects of my life.
So far, the aches and pains in my joints and feet are gone. I can hike 5 miles and still feel great whereas I used to feel quite tired and sore afterwards. Overall, I’m feeling great.

Before starting these peptides with Amanda’s guidance, my acne was completely out of control—from cystic breakouts to stubborn milia. Within just 3–4 days, I noticed a significant improvement: my active cysts began clearing up, and the redness subsided immensely.
My skin hasn’t felt this good in nearly two years. Additionally, since starting KPV, my digestion has improved dramatically. My body processes food much faster, and all post-meal bloating has completely disappeared.
I began Tirzepatide at a micro-dose, and the changes have been remarkable. My eating habits have improved dramatically—I feel full longer, my portion sizes have decreased, and, most importantly, my late-night cravings have completely disappeared. I used to wake up in the middle of the night, still half-asleep, raiding the kitchen out of sheer hunger. Since starting Tirzepatide, that has never happened—not once. In fact, I sleep through the night without interruption. I’m beyond grateful for both peptides!
