P-Long®: Increase the Size of Your Manhood Without Surgery
Reclaim your confidence, naturally.
If you’ve ever wished for greater length or girth, you’re not alone — over 50% of men feel the same. But risky surgeries and fillers aren’t your only option anymore.
P-Long® Protocol is the first clinically proven, non-surgical protocol to naturally increase size and improve function — safely and sustainably.
Why Choose the P-Long® Protocol?
Clinically Proven Results
100% of men in the P-Long® Study reported increased length and girth — with zero side effects. Many also experienced improved erectile function.
No Surgery. No Fillers.
Forget invasive procedures and temporary cosmetic fixes. P-Long® works with your body’s own regenerative ability for long-term benefits.
Customized, Doctor-Guided Care
Under Dr. Nguyen’s expert supervision, each step is tailored to you — with privacy, safety, and your goals in mind.

How the P-Long® Protocol Works
The P-Long protocol combines four powerful, proven elements:
- Platelet Rich Plasma (PRP) Injections: Stimulate natural tissue growth.
- Nitric Oxide Boosters: Support circulation and vascular health.
- RestoreX Traction Device: Gently lengthen and stretch.
- Dr. Joel Kaplan’s Vacuum Device: Enhance tissue expansion.
Each element works synergistically, helping you achieve noticeable, lasting results. Read more on our blog.
No Surgery, No Cosmetic Fillers
Consider this: other options for penile enhancement might come with potential side effects or unsatisfactory results. With P-Long®, Dr. Nguyen provides a safer and more effective solution that negates the need for invasive surgeries or temporary fixes.

Client Stories
"Incredible experience working with Dr. Khanh and the whole team at ART!! I came in for a recurring shoulder injury that I've had for years and nothing has worked to date. Dr. Khanh immediately started me on a protocol of peptides and within 12 weeks my shoulder pain is completely gone and I am in the best shape of my life."

"Knee feels good today. A noticeable difference. PRP takes a while to kick in right? The shockwave or combo must have helped a lot."
- Kevin, 3 weeks post-acute knee injury
"I'm on the 12th day of the LDN. I swear I'm in a better mood. I did start working out a lot so I'm sure that's helping but I'm almost elated I'm in such a good mood. Just wanted to say thanks... Glad to be feeling some relief..."
