Dear Friend,
Since 1991, I’ve dedicated my career to empower men with the best tools for penis enlargement and erection enhancement.
In my 30+ years of experience in men’s health, the most common question I get is, “How can I make my penis longer?”
That is why I developed DEEP: The Ultimate Penile Extender - an affordable, medical grade penile traction device that uses proven science to lengthen your penis and straighten curvature that is safe and comfortable to use.
Over 10 years of peer reviewed studies have shown that Penile Traction Therapy (PTT), significantly straightens curvature by as much as 20 degrees, and lengthens the penis by up to 3 inches (8 cm) in only a few months.
All it takes to start is 30 minutes a day.
We have helpful staff who are ready to answer your questions.
Happy Stretching!

How it Works
Penile Traction Therapy (PTT)
Penile Traction Therapy (PTT) uses mechanotransduction, or gradual expansion of tissue by traction, to form new collagen tissue by cellular proliferation.
PTT applies slight mechanical over-stretching, stimulating the cells to go through mitosis (or cell division) in the penile region to form new cells that are identical to the original cells.
Furthermore, when the smooth muscle tissue of the penis (corpus cavernosum) is placed under mechanical stress, myogenic stem cell activation occurs, which leads to repair of damaged tissue and an increase in cell size.
How to Use DEEP Penile Extender
Step 1
Insert the penis through the Penile Extender
Step 2
Adjust the stretch by twisting the tension rods on either side of the extender.
Step 3
Secure your penis to the stretcher with the silicone band

Customer Reviews

Frequently Asked Questions
How much longer can I get?
Average reported gains are 1-3 inches in length after 3-6 months when used daily, as directed.
When will I see results?
Most men report noticeable length in just 3 weeks. Significant gains of 1-3 inches are reported in the 3-6 month period.
Are results permanent?
Yes, consistent use of the extender will permanently straighten and increase the length of your natural erection.
What does stretching feel like? Does it hurt?
Penile traction therapy is a safe and proven method for male enhancement. The traction creates slight tension around your penis. Penis stretching should be a comfortable and easy experience.
I am not circumcised, can I still use the Penile Extender?
Yes, you can use the Penis Extender comfortably if you are circumcised or uncircumcised.
How often and for how long should I use the traction device?
We recommend using the Extender for at least 30 minutes every day. The more you use it, the faster the results.
Can DEEP be used with a penis pump?
For best results, use a penis pump after traction exercise for accelerated gains and recovery. The penis pump brings healthy blood-flow for accelerated regeneration and cell recovery. Additionally, the traction device stretches the erectile tissue, allowing the pump to fill your erection with maximum blood-flow, furthering your gains in penile thickness made with your penis pump.
What is the difference between traction devices, penile hangers, and penile weight systems?
Traction devices, bib-hangers, and weight systems all use the same stretching principle to elongate the penis. However, weight systems and bib-hangers are unsafe and should never be used for traction therapy. You cannot safely control the stretch, and you can easily hurt yourself. Additionally, weight systems and bib-hangers are not comfortable or practical to wear. DEEP Penile Extender is a safe, medical-grade device, with proven results.
Are there any risks or side effects?
No, when used as directed, penile traction therapy is a safe, non-invasive method to straighten and lengthen the penis.
I have a medical issue, can I still use the penile extender?
We recommend consulting with your physician if you have any penile or prostate medical issues.
