Precision Medicine for Your Wellness Journey

  • Testosterone Replacement Therapy

    Testosterone Replacement Therapy (TRT) is a treatment designed to restore healthy testosterone levels in individuals experiencing symptoms of low testosterone. This therapy can help improve energy, mood, muscle mass, libido, and overall well-being. At Freehold Athletic Club, Dr. Chalfin offers personalized TRT programs tailored to your health goals and hormone profile — helping you feel stronger, more focused, and revitalized.

  • GLP-1 Medications

    GLP-1 Medications are widely used to support healthy and sustainable weight loss. These medications work by regulating appetite, improving insulin sensitivity, and helping the body better manage blood sugar levels. Under the guidance of Dr. Chalfin, GLP-1 therapy can be a powerful tool for individuals looking to lose weight, boost energy, and improve overall metabolic health.

  • Peptide Therapy

    Peptide Therapy uses targeted amino acid chains (peptides) to stimulate natural processes in the body, such as hormone production, healing, and fat metabolism. This therapy can help improve muscle growth, increase energy, support weight loss, enhance cognitive function, and promote better sleep. At Freehold Athletic Club, Dr. Chalfin offers personalized peptide protocols to support your performance, recovery, and overall wellness.

  • Sustainable Fat Loss Plans

    Sustainable Fat Loss Plans focus on long-term, science-backed strategies to help you lose fat without extreme dieting or quick fixes. Dr. Chalfin’s approach combines nutrition guidance, lifestyle optimization, and hormone support to create lasting results. These programs are designed to boost metabolism, preserve muscle, and promote healthy habits — helping you achieve your goals and maintain them for life.

  • Bioidentical Hormone Replacement Therapy

    Bioidentical Hormone Replacement Therapy (BHRT) uses hormones that are chemically identical to those naturally produced by the body to help restore balance and improve overall well-being. BHRT can help alleviate symptoms of hormonal imbalance such as fatigue, mood swings, weight gain, low libido, and poor sleep. Dr. Chalfin customizes BHRT plans to support energy, mental clarity, and long-term vitality for both men and women.

  • Body Composition Optimization

    Body Composition Optimization focuses on improving the ratio of muscle to fat in your body — not just weight loss. Through customized fitness, nutrition, and hormone strategies, Dr. Chalfin helps clients increase lean muscle mass, reduce fat, and boost metabolic health. The goal is a stronger, healthier, and more efficient body that performs and feels its best.

  • Treatment for Fatigue & Low Energy

    Treatment for Fatigue & Low Energy focuses on identifying and addressing the root causes of persistent tiredness, brain fog, and lack of motivation. Dr. Chalfin uses a personalized approach that may include hormone optimization, nutritional support, and lifestyle adjustments to help restore energy levels, improve focus, and enhance daily performance — so you can feel like yourself again.
