Weight Loss That Actually Works.
Physician-directed Tirzepatide programs at Plump Medical Spa. Designed around your biology — not a one-size-fits-all protocol. Monitored, adjusted, and overseen by Dr. Amir Mortazavi, MD from start to finish.
Why Plump Uses Tirzepatide — Not Semaglutide
Most weight loss programs in Orange County use semaglutide (Ozempic, Wegovy). At Plump, Dr. Mortazavi made a deliberate clinical decision to use Tirzepatide (Mounjaro, Zepbound) exclusively — and the evidence supports it.
Tirzepatide is a dual GLP-1/GIP receptor agonist. GLP-1 controls appetite and insulin. GIP adds fat metabolism and a more favorable side effect profile. Clinical trials show Tirzepatide produces greater average weight loss than semaglutide — up to 20–22% of body weight — with improved tolerability for many patients.
What GLP-1 Medications Do
Tirzepatide works by mimicking hormones your body naturally produces after eating. It signals fullness to your brain, slows gastric emptying, stabilizes blood sugar, and reduces appetite — making it significantly easier to eat less without feeling deprived.
Programs & Pricing
All programs are physician-directed by Dr. Mortazavi. Dosing is individualized at consultation and adjusted based on response and tolerability — not a fixed protocol applied to every patient.
GLP-1 Microdosing Program also available — $750 for 90 days. A physician-directed sub-therapeutic dosing protocol for patients focused on metabolic optimization, weight maintenance, or who have experienced side effects at standard doses.
Vitamin B12 & Folic Acid injections — $75. Energy and metabolism support available as a standalone or complement to any weight loss program.
How It Works at Plump
Who This Is For
Tirzepatide programs at Plump are appropriate for adults who have struggled to lose weight through diet and exercise alone, have weight-related health concerns, or are seeking a sustainable long-term approach rather than a short-term fix. A consultation with Dr. Mortazavi determines whether the program is clinically appropriate for you.
This is not appropriate for patients who are pregnant, have a personal or family history of medullary thyroid carcinoma or MEN 2, or have certain pancreatic conditions. Full medical history review at consultation.
Physician-Directed — Not Telehealth
Every weight loss patient at Plump is evaluated and monitored personally by Dr. Mortazavi. This is not a telehealth prescription service. No online questionnaires, no automated refills, no remote oversight. Plump's approach integrates weight management with the broader aesthetic and longevity medicine context that makes it uniquely suited to address body composition and facial appearance together.
Frequently Asked Questions
Do you offer semaglutide (Ozempic or Wegovy) at Plump?
No. Plump Medical Spa uses Tirzepatide exclusively — not semaglutide. Dr. Mortazavi made this clinical decision based on evidence showing Tirzepatide produces greater average weight loss with a more favorable tolerability profile due to its dual GLP-1/GIP mechanism.
How quickly will I lose weight on Tirzepatide?
Most patients begin to notice appetite reduction within the first 1 to 2 weeks. Meaningful weight loss typically becomes visible at 4 to 8 weeks. Clinical trials show average weight loss of 15 to 22% of body weight over 72 weeks. Individual results vary based on dose, adherence, and metabolic factors.
What is the GLP-1 Microdosing Program?
The 90-day GLP-1 microdosing program uses sub-therapeutic doses for patients who want the metabolic and appetite-regulating benefits of GLP-1 without the full weight-loss dosing side effect profile. It is appropriate for weight maintenance, metabolic optimization, or patients who experienced side effects at standard doses. The full 90-day program is $750.
What is "Ozempic face" and can Plump address it?
Rapid weight loss from GLP-1 medications can cause significant facial volume loss — gaunt appearance, hollowed cheeks, and loss of jawline definition commonly referred to as "Ozempic face." Plump is one of the only practices combining GLP-1 prescribing and aesthetic medicine, offering a Facial Volume Loss Assessment ($350) for GLP-1 patients to proactively map and restore volume with Sculptra or dermal fillers before loss becomes visually significant.
