“The P-Long Protocol represents one of the most studied, evidence-based approaches to natural male enhancement — and the complete 20-minute video below walks through everything you need to know.” — Dr. Lamia Gabal, MD

Many men look for safe and effective ways to improve sexual performance, including concerns about size, sensation, and erectile function. The P-Long® Protocol offers a natural solution — without surgery or risky procedures.

Created by board-certified urologist Dr. Judson Brandeis, this innovative treatment uses Platelet-Rich Plasma (PRP) injections, along with specialized devices and supplements, to help increase length, girth, and overall sexual wellness.

Understanding the P-Long Protocol

The P-Long Protocol centers around a modified P-Shot® — a treatment that uses Platelet-Rich Plasma (PRP) from your own blood. PRP is injected into specific areas of the penis to boost blood flow and support tissue growth, which can lead to increased size and better erectile function.

This treatment is part of a comprehensive program that also includes a starter kit with the AFFIRM Nitric Oxide Booster, the AndroDEEP Traction Device, and your choice of Dr. Joel Kaplan or Vaxaid Vacuum Device — together creating a multi-modal approach to natural male enhancement.

The Protocol

Four Coordinated Components

The protocol’s strength lies in how four distinct elements work together — each amplifying the others’ effects over the six-month regimen.

1
Platelet-Rich Plasma (PRP) Injections

Administered once a month for six months under ultrasound guidance. PRP injections promote tissue regeneration and stimulate growth for real measurable gains.

2
AFFIRM Nitric Oxide Booster

This nutritional supplement supports erectile health by naturally boosting nitric oxide levels, improving blood flow, and enhancing performance. Available in-office at PMG.

3
AndroDEEP Traction Device

Designed for daily at-home use, the traction device applies gentle, consistent force to promote tissue expansion and maximize PRP effectiveness.

4
Vacuum Erection Device

Choose Dr. Joel Kaplan or Vaxaid pump based on preference. Aids in achieving firmer, fuller erections while improving blood flow throughout the protocol.

Realistic Timeline

When Will You See Results?

Setting the right expectations is one of the biggest predictors of success. Here’s what actually happens month-by-month.

Cellular Regeneration

Wk 6-16

Why Consistency Matters Most

The most common reason men don’t see optimal results isn’t the protocol — it’s quitting during the early cellular regeneration phase when nothing looks like it’s happening. Stay the course.

Clinical Evidence and Expectations

The effectiveness of the P-Long Protocol is supported by published clinical research. In the Brandeis et al. 2023 study, healthy men experienced significant gains in both length and girth after completing the six-month regimen — averaging 0.805 inches in length and 0.469 inches in girth, with 100% reporting improved erectile function and zero adverse events.

Results may vary based on individual factors, but long-lasting improvements in size and function are anticipated. Unlike temporary solutions such as fillers, the P-Long Protocol stimulates actual tissue remodeling — providing lasting benefits for sexual wellness.

A Lasting Result
Unlike temporary fillers, P-Long produces long-lasting results — the protocol stimulates real tissue growth, not temporary volume.
Also For Men With ED

P-Long + ED Enhancement

While the primary goal of P-Long is size enhancement, 100% of participants in the published study reported improved erectile function. At Prestige Medical Group, we routinely treat men with erectile dysfunction using a customized P-Long approach.

Based on your SHIM score at consultation, Dr. Gabal may recommend adding complementary treatments:

The right combination is determined case-by-case at your consultation — one of the ways PMG’s P-Long program is uniquely positioned to help men with ED, not just enhancement candidates.

Common Questions

Addressing Common Questions

Does it hurt?

The procedure involves two injections into the shaft of the penis. Discomfort is minimized with numbing medication. Additional options like Pronox (nitrous oxide) are available for those seeking a more comfortable experience.

Does it help with erectile dysfunction?

Yes. 100% of participants in the published clinical study reported improved erectile function. At PMG, we customize the protocol for men with ED — potentially adding ShockWave Therapy, Apex RF, or Exosome Therapy based on your SHIM score.

How fast will I see results?

The first 6 weeks are a cellular regeneration phase with no visible changes yet. Most patients begin seeing visible results around month 4, with peak results at the 6-month study endpoint.

Is there downtime?

Mild swelling or bruising may occur, but most patients return to normal activities the same day. Zero adverse events were reported in the published clinical study.

Does it really work?

In the published Brandeis et al. 2023 study, every participant had positive results — averaging 0.805 inches length gain and 0.469 inches girth gain over 6 months. See our before & after photos for real PMG patient outcomes.

Am I a good candidate?

Good candidates are healthy adult men committed to daily traction and vacuum device use, willing to be nicotine and marijuana-free during treatment. Dr. Gabal evaluates each patient individually — including SHIM score assessment for men with ED concerns.

Certified P-Long Provider

Why Choose PMG?

P-Long is not a DIY protocol or a technique any office can replicate. Prestige Medical Group is a certified P-Long provider with a direct relationship with Dr. Brandeis’s office — the developer of the protocol. This ensures you receive the authentic protocol as researched, published, and continuously refined by its originator.
