Trusted By Over 100,000 Men

After my 1st week of pumping coming out of the shower... my wife said, "it looks so defined....like if you've been working it out." Then at the beginning of my 3rd week my wife said, "there's a big bulge through your pants... pull it out." As i did she couldn't keep her hands off it... squeezed it, and kept repeating... "it looks so muscular, so healthy, so thick... keep it up!" If this happened only after a couple of weeks of pumping I can't wait to see in a couple of months. I want to thank Dr. Kaplan and his team for investing in men.

I get so turned when I see my husband after he uses the pump - I looooove to feel how hard and big he is in my hands! We use the pump all the time.

Christina, 48 years old, CT

I’ve never had any issues with my guy but I’m all about improving and staying as healthy as possible in all ways! I started off with a length of 8.5 inches long and 6 inches in girth. I am now 8.7 inches long and 6.3 in girth... I love the feeling when pumping and after with all the extra blood in my penis and balls. The biggest change I have notice is that throughout the day I’m much bigger just hanging around.... I need to buy bigger pants to fit my growing guy!

Sam, 44 years old, Dallas, TX

I am just starting week 7 of my pumping with the whopper and already I have gained more than half an inch of penis girth, .4 inches of head girth, and .2 inches of penis length. I am more than satisfied with the whopper and will continue to use it happily use it so that I can see more gains in my penis so that I can continue to give future partners the height of their pleasure that is possible.....

How to Use Your Pump


Lubricate the bottom of the cylinder and the base of the penis with Dr. Joel Kaplan's Pumper's Lube.

Pump your penis and scrotum while flaccid.

Pump up your erect penis. As you pump, you will immediately see your erection start to grow.

Pump the penis head with the Head Enlarger (optional).

For best results, secure Dr. Joel Kaplan’s Leather Strap around your penis and scrotum for 30 minutes after your pump session. This keeps the penis engorged with blood, expanding your blood vessels. This FREE-GIFT is included with your purchase!

How it Works

Dr. Joel Kaplan’s Dual Cylinder Enlargement Protocol

Dr. Joel Kaplan developed a 2-Phase Enlargement Program that exercises the penis in 2 different ways. This will lead to bigger, harder, and longer lasting erections.

Erection Expansion

Dr. Joel Kaplan’s exercise targets the erectile tissue located in the penis shaft. Using slight vacuum pressure, the pump draws blood-flow into the penis, expanding your erection. This expansion in turn creates micro-tears in the erectile tissue, facilitating new cell growth to repair and rebuild. This process both rejuvenates and increases the size of the penis.

Phase 2: Stimulate the Buried Shaft

About 30% of the penis is located inside the body. Dr. Joel Kaplan developed a 2nd cylinder that fits over the penis and scrotum to stimulate the buried shaft of the penis. This exercise additionally tugs on the suspensory ligament located behind the penis, elongating the penis even in a flaccid state.

Proven Results

The National Institutes of Health library has accumulated volumes of evidence about Vacuum Erection Devices (VED - also known as penis pumps) and their positive effects on penis length, thickness, and erection quality.

The Results are Extraordinary!

Vacuum erection devices have indeed shown promise in not only increasing subjective length... VED use can thus promote corporal expansion...

Frequently Asked Questions


Most men prefer the Automatic Pump because it is a Hands-Free pumping experience, making penis pumping convenient, easy and pleasurable. The Automatic Pump pumps for you - it detects if the pressure changes, and will adjust the pressure to the preset you choose. However, it has a soft humming sound - our customers say it has a similar sound level as a microwave or strong fan. If discretion is the priority - choose the Manual Pump - it is completely silent, ensuring 100% privacy.

Average reported gains are 1-3 inches in length and up to 25% in thickness after 10-12 months of following Dr. Joel Kaplan’s pumping guidelines.

You will see results after the very first time you use it. You’ll get a bigger erection every time you pump. After a few weeks of consistent pumping, you will start to maintain those results permanently. Most men achieve maximum size after 10-12 months of consistent pumping.

Yes, consistent use of the pump will permanently increase the size of your natural erection.

For best results, we recommend following one of two exercise programs that is included with Dr. Joel Kaplan pump systems every other day for about 20 minutes.

Yes, you can have sex after using the pump, your erection will be bigger and harder. To maximize growth, we recommend that you do not have sex after you pump for 2 hours.

Absolutely! Your pump includes KaplanCare™, our warranty, support, and education program. Contact us, either online or by phone, with any question you have.

Your privacy is very important to us. We send all shipments in a plain shipping box with no special markings.

We have customers of all ages from 18 - 90 years old who use our penis pumps for penis enlargement, reverse penile shrinkage due to age, erectile function, Peyronie's disease, and masturbation.

Penis pumping is a safe and pleasurable method for male enhancement. The suction creates a pleasurable tension around your penis. Some men use penis pumps for masturbation because it feels so good. If you encounter any pain or discomfort, just decrease the pressure. Penis pumping should be a comfortable and enjoyable experience.

Both water pumps and air pumps use vacuum pressure to bring blood-flow into the penis. However, water pumps can only be used in the shower. This becomes inconvenient if you want to use a pump before sex, or if you want to watch porn online while you pump. Most importantly, it is not safe to pump without a pressure gauge. Water pumps do not come with a pressure gauge - it's like driving a car without a speedometer! Most men over-pump and hurt themselves because they don't know how much pressure is inside the pump! Never buy a pump without a pressure gauge.
