What Medical Weight Loss Treatments Does Dr. Fortino Offer?
Dr. Fortino offers a range of physician-supervised medical weight loss treatments for adults who want a medically guided approach to losing weight and improving their health.
As a medical weight loss doctor, Dr. Fortino evaluates each patient before recommending prescription treatment.
Options may include GLP-1 weight loss treatment with Semaglutide or Tirzepatide, Phentermine weight loss treatment, nutrition counseling, body composition analysis, and vitamin or amino acid therapy when medically appropriate.

For current pricing and special offers, speak with a Patient Care Coordinator during your free telephone consultation.
Will insurance pay for Semaglutide or Tirzepatide weight loss treatment?
Insurance coverage for brand-name GLP-1 medications varies and typically requires patients to meet specific medical criteria, such as a qualifying BMI or related health condition. Some plans may require prior authorization.
Because we offer compounded GLP-1 medications, insurance typically does not apply.
Where Can I Get MIC Lipotropic and B12 Injections Near Me?
Dr. Fortino offers prescription MIC lipotropic and Vitamin B12 injections at his Philadelphia and South Jersey offices.
Additional injectable vitamin and amino acid therapies may include L-Carnitine, Glutathione, L-Lysine, L-Arginine, Taurine, and Tri-Amino Blend.
Because these are prescription treatments, Dr. Fortino evaluates each patient to determine which injections, if any, may be medically appropriate based on individual health needs.
Does Dr. Fortino Prescribe Phentermine for Weight Loss in Philadelphia?
Dr. Fortino offers Phentermine weight loss treatment for appropriate patients. This prescription appetite suppressant may help reduce hunger and support portion control as part of a medically supervised weight management plan.
Because Phentermine is not appropriate for everyone, Dr. Fortino determines candidacy and monitors treatment based on each patient’s individual health needs and response.
Does Dr. Fortino Offer Testosterone Replacement Therapy (TRT) and Low T Treatment for Men?
Yes. Dr. Fortino provides Testosterone Replacement Therapy (TRT) and Low T treatment for men at his Philadelphia and South Jersey offices.
Treatment begins with a medical evaluation and laboratory testing to assess symptoms, testosterone levels, and other health factors that may contribute to Low T symptoms.
When medically indicated, Dr. Fortino develops and monitors an individualized treatment plan based on laboratory results, symptoms, overall health, and response to therapy.
Where Can I Get a Body Composition Analysis in Philadelphia?
Dr. Fortino offers SECA Alpha body composition analysis at his Philadelphia and South Jersey offices. You do not need to be enrolled in a medical weight loss program to use this service.
Unlike a traditional scale, the SECA Alpha provides a more detailed assessment of body fat, muscle mass, and other body composition measurements. These results can provide useful information for tracking changes in body composition over time, whether your goals involve weight management, fitness, or maintaining muscle mass.
Body composition analysis is available as a standalone service by advance appointment, as well as for patients receiving care through Dr. Fortino’s practice.
Patients can also use the SECA myAnalytics app on their phone to view their results, see changes in their body composition, and track their progress over time.
Does Dr. Fortino Offer Diet and Nutrition Counseling for Weight Loss?
Yes. Nutrition is an important part of Dr. Fortino’s approach to medical weight management.
His philosophy is not based on fad diets, extreme calorie restriction, or simply getting patients to a lower number on the scale.
Instead, Dr. Fortino emphasizes a balanced approach centered on high-quality protein, healthy fats, fiber-rich foods, and whole-food nutrition.
Ultimately, the focus is on developing eating habits that support better health, strength, body composition, and long-term weight management—not simply eating less.
We also track visceral fat, body fat, and skeletal muscle mass with advanced body composition analysis, helping monitor meaningful changes throughout your weight loss journey.
