My Comeback Story: Losing Weight, Gaining Power

Boxing has been a part of my life since I was a teenager. I’m not a world champion or anything like that — but I’ve trained, fought, and sparred enough rounds to know what discipline means.

Over the years, though, life got in the way. Between work, family, and stress, my training slowed down. My diet wasn’t clean anymore, and the pounds started creeping up.

When I finally checked my stats, my BMI was over 31 — way higher than it should be for someone who used to make weight for fights. I could still throw a punch, but I didn’t feel light on my feet. My energy dropped, my recovery took longer, and I was tired of feeling sluggish.

That’s when I decided to do something about it — but I wanted help from real medical professionals, not just another “fitness challenge.” That’s how I found ​Florida Weight Loss Center and Dr. Sergey Terushkin, a bariatric and general surgeon who offers doctor-supervised medical weight loss both in person and through online consultations. ​

I didn’t have to drive anywhere or miss training. I booked an online consultation and connected with one of the clinic’s providers through telehealth. It was fast, professional, and easy to schedule around my workouts.

They asked about my history, energy levels, diet, and goals. Once we went through everything, the doctor told me I was a great candidate for ​tirzepatide — a medical weight-loss medication that helps reduce appetite, control cravings, and improve metabolism.

It wasn’t some fad or miracle pill. The doctor explained how it worked and emphasized that dosing would depend on how my body responded. That’s what convinced me — it was personalized and medically guided.

The Plan: Start Smart, Adjust As You Go

Dr. Terushkin’s team started me on a low dose, around 2.2 mg, to let my body adapt. The plan was to stay there for a few weeks and then possibly move up to 4.4 mg or 6.6 mg depending on progress and tolerance.

They explained that the goal wasn’t just to lose weight fast — it was to do it safely and maintain muscle mass. That’s important for anyone who trains or used to compete. You don’t want to lose strength, you want to lose fat.

Every step of the way, the team checked in online. I could message them for advice, track my progress, and adjust my dose under doctor supervision. That kind of structure made it easy to stay consistent — no guessing, no confusion.

The Results — Lighter, Sharper, Stronger

After the first month, I dropped close to 10 pounds. My appetite changed completely. I didn’t crave junk food, and I naturally started eating smaller meals. My focus came back, and I actually looked forward to training again.

By the third month, I’d lost around 25 pounds total. My BMI dropped under 28, and I could move better in the gym. My punches felt sharper, my footwork smoother. Even my sparring partners noticed the difference.

I wasn’t just lighter — I was faster, clearer, and more disciplined. It felt like getting back to my old self again, but with smarter habits this time.

Adding NAD⁺ Therapy for Energy and Recovery

One of the staff members suggested I try NAD⁺ therapy to help with recovery and overall energy. I’d heard of it from other athletes but never tried it. They explained that NAD⁺ (nicotinamide adenine dinucleotide) is a natural molecule your body uses to produce energy and repair cells.

As someone who trains hard, that sounded like exactly what I needed. I started a ​monthly NAD⁺ injections — around $350 per month or $450 for two months, including everything delivered to me.

Within two weeks, I noticed a huge difference. My energy was steady all day, even after long workouts. My recovery improved, soreness dropped, and I could go harder in training without crashing later. It wasn’t hype — it actually worked.

NAD⁺ became part of my weekly routine, just like my gloves and wraps. It gave me that extra edge physically and mentally.

Why I Recommend Dr. Terushkin and His Team

What I respect most about Florida Surgery & Weight Loss Center is that they keep things real. They don’t overpromise, they don’t sell fake “quick fixes.”

Their introductory plan starts at $36.95 per week, which makes it affordable for almost anyone to start. From there, the doctor personalizes the program — adjusting your dose, checking progress, and adding optional treatments like NAD⁺ for energy.

Dr. Terushkin himself is straightforward and professional. He explains things clearly and focuses on results that make sense for your body type and lifestyle. Whether you’re a driver, office worker, or ex-athlete like me — he builds the plan around you.

Back in Control — Inside and Outside the Ring

A few months later, I’m down 30 pounds, my stamina is back, and I’m training smarter than ever. My blood pressure’s normal, my energy is consistent, and I’m finally proud of how I look and feel.

What made it work wasn’t just the medication — it was the support system. The online consultations kept me connected to real professionals who guided me every step of the way. No gym membership or crash diet could have done that.

Now, when I step into the ring to train, I feel like I’m in control again — not just physically, but mentally.

If you’re a fighter, athlete, or just someone trying to get back in shape, don’t wait until your body forces you to stop. Reach out for help, even if it’s online. The right doctor can get you back in your rhythm faster than you think.

For me, that doctor was Dr. Sergey Terushkin and his team at Florida Surgery & Weight Loss Center — and they helped me fight my toughest opponent yet: myself.
