Complete training course

​

The results you achieve with this device depend on how attentively you study the course material. Reading and watching the lessons will take far less time than the daily stretching itself. A few hours of focused learning now will save you months of ineffective work later. It is better to avoid common mistakes from the start than to discover them after wasting time and your initial “growth potential.”

This course answers about 90 % of the questions you may have now—or will have later. Please do not rush to support if something seems unclear: the information is presented in detail in both text and video. Reading and watching both formats is strongly recommended; repetition helps retention.

Main purposes of the A-Ext stretcher

1. Preventing the progression of Peyronie’s disease — slows curvature and further shortening of the penis.

2. Correcting axial curvature of the shaft (except for pronounced central “arc” curvature, where improvement is modest).

3. Post-ligamentotomy traction — replaces a classic rod extender to draw out the inner shaft after the suspensory ligament is cut.

4. Increasing penile length and girth in healthy men.

Temporary contraindications

Before starting, treat any chronic or infectious genitourinary conditions or bring them into remission:

• Varicocele stage 2–3 with pain

• Chronic prostatitis outside remission

• HPV lesions near the urethral meatus (papules or condylomas)

• Hydrocele

• Any inflammatory infections of the genitourinary tract

• Circumcision performed less than 2 months ago

Age and health factors

Optimal age for traction-based growth is up to 45. From 45–60 gains are harder because regenerative capacity declines. Conditions such as diabetes or any autoimmune disorder can also reduce results.

“Newbie gains”

The first 3–4 months of any traction routine are usually the most productive. You either gain during this window or, if you overload tissues incorrectly, you may stiffen them and lose part of your inherent potential. A second attempt can still work, but without the same initial “credit.” Therefore, start the program well prepared; the first attempt is the most important.

If you are doing everything correctly and see +3–4 mm in length or girth during the first month, do not stop. Continue until growth naturally stalls (typically after 3–4 months), then switch to a new program to restart progress.

Average effectiveness

Among 100 men who follow continuous traction, about 70 % achieve at least +10 mm. Main reasons for little or no gain:

1. Incorrect load or irregular sessions

2. Health issues (systemic diseases reduce effectiveness)

3. Tissue resistance — in 10–12 % of men, the body resists deformation and forms scar-like reinforcement instead of adapting. The course includes step-by-step programs— from light to stronger loads with supplementary exercises—to “break through” this barrier.

How traction works

Like any stretcher, extender, or hanger, the device applies long-term, steady tension that creates micro-traumas. During healing, new tissue (not scar tissue) fills the gaps, lengthening and slightly thickening the shaft. Micro-traumas must be the right size—something you cannot measure directly. Practical research shows the most effective range for most men; this is marked on our tensioners as dots from 750 g to 2000 g (allow +100–200 g for belt compression).

Getting started

A brief starter program follows in the next section. Watch the video on how to put on / remove the stretcher, perform the exercises, and keep the training log. Without a log you are “running blind.” The video explains exactly how to record and interpret your data.

Among the so-called "natural penis enlargement" communities, there is a list of special penis measurement techniques that are borrowed from English-language similar forums
Here are the main 9 measurement methods used;

(Measurement abbreviations)

• NBPEL — Non-Bone-Pressed Erect Length
  Length of the fully erect penis (ruler rests on the skin).

• BPEL — Bone-Pressed Erect Length
  Length of the fully erect penis with the ruler firmly pressed to the pubic bone.

• EG — Erect Girth
  Circumference when 100 % erect.

• NBPFSL — Non-Bone-Pressed Flaccid Stretched Length
  Length of the stretched flaccid penis (ruler on the skin).

• BPFSL — Bone-Pressed Flaccid Stretched Length
  Length of the stretched flaccid penis with the ruler pressed to the bone.

• NBPFL — Non-Bone-Pressed Flaccid Length
  Length of the relaxed penis.

• BPFL — Bone-Pressed Flaccid Length
  Length of the relaxed penis with the ruler pressed to the bone.

(The list above repeats some items for completeness; the names match those used on NUP forums.)

The three measurements that really matter

​

​

​

​

​

​

​

​

​

​​​​​​

1. Absolute length — BPEL

2. Girth — EG

3. Absolute stretch length — BPFSL

Tracking just these three is enough to see progress clearly, e.g., every 30 days.

• NBPEL (ruler only on the skin) is less reliable: the fat pad can change by up to 1.5 cm over a year, and body hair shifts the contact point.

• You are free to record all nine metrics, but using only the three precise ones keeps progress monitoring simple.

Training schedule basics

A set (or “approach”) = one continuous period of wearing the stretcher at a chosen tension.
Sets follow one another every 90–120 minutes.

Between sets you must “reload” correctly:

1. Near the end of a set—especially the 3rd or 4th—you may feel mild pain or numbness in the glans because blood and lymph circulation slows.

2. Remove the cap and do 40 light jelqs (about 30–40 seconds) to restore flow.

3. Immediately start the next set. No idle pauses.

Typical cycle

• Put the cap on, apply the belt tension — 90 min set

• Remove, jelq × 40

• Put the cap back on — start the next 90 min set

If your job makes two-to-three re-loads a day impractical, stretch each set to 120 minutes; you will then have just one or two re-loads per day.
