Overview
Sarcopenia (age-related muscle loss) can be slowed or reversed with the right interventions.
Peptides, testosterone therapy, and creatine all support muscle growth when combined with resistance training and protein-rich nutrition.
Lifestyle foundations—training, sleep, and recovery—are essential for lasting results.
HealthSpan Internal Medicine uses physician-supervised, individualized plans for safety and long-term success.
Key Points
Sarcopenia is reversible when addressed early.
Muscle tissue supports metabolism, bone density, and overall healthspan.
Peptides such as growth hormone secretagogues and BPC-157 may enhance repair.
Testosterone and DHEA support muscle protein synthesis when clinically indicated.
Creatine is one of the safest, most effective supplements for muscle and brain health.
Exercise remains the foundation—therapies enhance, not replace, training.
What Sarcopenia Really Means
Sarcopenia is more than just getting weaker with age. It’s a medical condition involving measurable loss of muscle mass, strength, and mobility. By age 60, up to one-third of adults show signs. Left unchecked, it leads to fatigue, poor balance, and loss of independence.
Muscle is not just for movement—it’s a metabolic organ that helps control blood sugar, maintain bone strength, and regulate inflammation. Preserving it protects your overall healthspan.
The Foundations of Reversing Sarcopenia
Before introducing advanced therapies, three fundamentals must be in place:
Resistance Training: Strength training is the #1 proven way to rebuild muscle and slow aging. Aim for 2–3 sessions per week using major muscle groups.
Protein and Nutrition: Most adults need 1.0–1.2 grams of protein per kilogram of body weight daily. Evenly spaced, protein-rich meals maximize repair.
Rest and Recovery: Muscles grow during rest, not during workouts. Prioritize sleep, hydration, and stress control.
Once these basics are solid, peptides, hormones, and supplements can amplify results.
Peptides and Muscle Regeneration
Peptides are small amino acid chains that act as cellular messengers to stimulate healing and repair. For muscle health, they work by improving growth hormone signaling, promoting tissue recovery, and controlling inflammation.
Common peptides studied for sarcopenia include:
Growth Hormone Secretagogues (such as CJC-1295, Ipamorelin, Tesamorelin): These peptides boost the body’s natural growth hormone release, helping build lean muscle and improve recovery.
BPC-157 (Body Protection Compound): A regenerative peptide being studied for tissue repair and inflammation reduction. Used clinically under supervision for recovery support.
Thymosin Beta-4 (TB-500): Encourages cell migration and tissue healing after injuries or surgery.
Peptides are helpful tools—but they work best alongside proper training and nutrition, and should always be used under physician supervision.
Hormones: Testosterone and DHEA
Hormones are essential for maintaining muscle mass. Both men and women experience gradual hormonal declines with age.
Testosterone supports protein synthesis, bone density, and motivation. Replacement therapy, when indicated, can safely restore vitality and muscle mass.
DHEA supports adrenal and hormone balance, aiding in recovery and muscle preservation.
Thyroid hormones regulate metabolism, and suboptimal levels can slow muscle growth.
At HealthSpan, all hormone treatments are evidence-based and closely monitored with lab testing for safety.
Creatine: Small Molecule, Big Impact
Creatine monohydrate is one of the most proven supplements for both muscle and brain health. It enhances energy production during high-intensity exercise and supports muscle strength and cognitive performance in older adults.
Typical dose: 3–5 grams per day.
Creatine is safe for healthy adults and works best when combined with resistance training and adequate protein intake. It helps protect muscle tissue from age-related decline and supports improved recovery.
Can Sarcopenia Be Reversed?
Yes. Muscle loss can be stopped and even reversed with consistent training, proper nutrition, and medical supervision. Studies show that even people in their 70s and 80s can rebuild muscle within months through resistance training, higher protein intake, and supportive therapies.
Peptides, hormone optimization, and supplements like creatine enhance these gains by improving recovery and muscle protein synthesis. Consistency is the key to lasting results.
How We Treat Sarcopenia at HealthSpan Internal Medicine
Our approach combines functional medicine testing with modern, evidence-based therapies to address the root causes of muscle decline.
Comprehensive Testing: We assess hormones, inflammation, nutrients, and body composition.
Personalized Strength Plan: Safe, progressive resistance training tailored to each patient.
Nutritional Optimization: Protein timing, creatine guidance, and micronutrient support.
Targeted Therapies: Peptides (such as BPC-157) and hormone balancing when appropriate.
Ongoing Monitoring: Regular labs, follow-ups, and strength tracking for safety and progress.
Our goal is sustainable progress—not quick fixes—to help you stay strong, independent, and active for life.
When to Seek Medical Guidance
Contact your clinician if you experience:
Rapid muscle loss or persistent weakness
Fatigue, low energy, or poor recovery from exercise
Signs of hormonal imbalance (mood swings, low libido, sleep changes)
Muscle or joint pain that limits movement
Early evaluation can prevent progression and make recovery faster.
