What Our Customers Say
"My urologist actually recommended AndroDEEP after my prostate procedure to reverse the shrinkage I experienced. Best decision I made for my recovery and confidence."
"After 3 months of consistent use I measured a difference of almost 1 inch. My wife noticed too. I just wish I'd started sooner."
"Honestly, it looks like a medieval torture device, but I was really insecure about my length, so I decided to give it a shot. Boy, was I wrong. It's easy to put on, super comfortable. It takes a little bit to find the right setting, but once you get the right fit, you can wear it for hours without any discomfort."
"I've tried jelquing, weights, you name it. But all of those methods are tedious and really inconvenient (and frankly dangerous), I can't believe I got away unscathed. Androdeep is safe and easy to use. Nearly half an inch gain in 2 months."
"Takes a few days to get the hang of fitting it properly, but once you figure out the silicone band technique it's straightforward. I wear it 4–5 hours a day while working from home. Seeing steady progress."
"Discreet shipping, well-packaged, and the instructions were clear. I'm at week 8 and already adding extension rods. The progressive sizing system is genius - you can literally see it working."
THE SCIENCE BEHIND TRACTION
How Penile Traction Therapy Works
When gentle, sustained traction is applied to tissue, the body responds by producing new cells — a biological process called mechanotransduction. This is the same principle used in orthopedic bone lengthening and tissue expansion surgery.
Penile traction devices apply a controlled stretch along the penile shaft. Over weeks and months of consistent use, the body generates new tissue, resulting in measurable, permanent gains in both flaccid and erect length.

CLINICAL EVIDENCE
Published Clinical Data — What the Research Shows
Across 20+ studies and 500+ participants: average gains of 0.5–1+ inches over 3–6 months, with 94% achieving measurable results.
44 men used a traction extender for 6 months alongside hormonal therapy. Average erect length increase was 1 inch (2.5 cm) from the traction device alone.
93 patients over 12 weeks. Traction group gained an average of 0.7 inches (1.8 cm) in stretched penile length. Results were dose-dependent — more hours per day produced greater gains.
23 subjects showed flaccid length increase from 3.5 to 4.1 inches (8.8 to 10.5 cm) over 3 months. Stretched length increased from 4.5 to 5.2 inches. Results were statistically significant (P < 0.05).
Patients using a traction device 4–6 hours daily showed a mean increase of 0.5 inches (1.3 cm) in flaccid length. Results persisted 6 months after discontinuation.
110 men randomized in a controlled trial. 94% of the traction group achieved measurable length increases (avg 0.6 inches). 77% saw improved curvature.
Foundational study showed average growth of ~0.2 inches per month in erection over 3–6 months. Length increases were proportional to daily wear time.

Frequently Asked Questions
Everything you need to know before ordering.
Yes. The medical-grade silicone band and protective cushion are designed for extended wear. Most users report comfortable use within the first few days. Start with shorter sessions (2–3 hours) and build up as your body adapts.
Completely discreet. All orders ship in plain, unmarked packaging with no indication of the contents. The return address shows our corporate name only. US orders ship free within 1 business day.
We offer a 30-day money-back guarantee. If you're not satisfied, return the device within 30 days for a refund.
Clinical studies show gains starting at just 2–3 hours per day. More hours produce faster results — up to 8 hours maximum. Many users wear it while working from home, watching TV, or during daily activities. Even 2–3 hours produces measurable results over time.
Yes. The Gontero study (BJUI, 2009) specifically measured results 6 months after patients stopped using the device — gains were maintained with no regression. The device stimulates new cell growth through mechanotransduction, a permanent biological change.
Absolutely. Traction therapy can be combined with vacuum pumps, supplements, or other treatments. The hypogonadism study showed that combining traction with hormonal therapy produced even greater results (2.5 inches total gain). Consult your healthcare provider for personalized guidance.
Most users notice changes within 4–8 weeks. Clinical studies measured significant gains at the 3-month mark (avg +0.7 inches flaccid). Maximum results are typically seen at 4–6 months. The key is consistency.

SIMPLE SETUP
How to Use AndroDeep
Four simple steps — most users are comfortable within the first few days.
Measure & Calculate
Measure your erect length, subtract 1.5 inches. That's your starting device size. The device ships at a 3-inch baseline.
Add Extension Rods
Use the included 1.5 in, 0.75 in, 0.2 in, and 0.1 in rods to dial in your exact personal size. Snap the upper support back into place.
Fit Comfortably
Apply the protective cushion, slide through the base ring, and secure comfortably with the medical-grade silicone support band. Lock into the fasteners.
Wear & Progress
Start with 2–3 hours daily and build up gradually. Add extension rods every 5 days as you adapt. Remove every 2 hours for a brief rest.
Most users report comfortable all-day wear within the first week. The progressive sizing system lets you start easy and build up at your own pace.
ADAPTATION SCHEDULE
Progressive Adaptation Protocol
Results are dose-dependent — more hours per day produces greater gains. Follow this schedule to build up safely and comfortably.
| Period | Device Size | Daily Duration |
|---|---|---|
| Days 1–5 | Initial personal size | Up to 3 hours (2-hour intervals) |
| Days 6–10 | Add one 0.2-inch rod | Up to 6 hours (2-hour intervals) |
| Days 11–15 | Add another 0.2-inch rod | Up to 8 hours (2-hour intervals) |
| Day 15+ | Continue adding rods as tolerated | Up to 8 hours daily (max) |
Working from home? 4–6 hours during your workday.
Office job? 2–3 hours in the evening.
Weekends? Extended sessions while relaxing at home.
