DP-4000 is manufactured by CTC Company. This US-based company has been in business for over 45 years and is specializing in designing penis enlargement products.
CTC Company currently has four different products on their website, DP-4000 being the latest pump.
Air pumps like DP-4000 can yield up to 1.5 inches growth within the initial 1-3 months of usage. It is carefully designed to provide controlled pulsation in order to allow the penis to expand and stretch to its maximum capacity.
DP-4000 produces an erotic sensation to the user as a training to avoid premature ejaculation, thus leading to a stronger stamina. Its changing vacuum environment promotes better blood circulation. This makes it easier for the body to supply more blood to the penis. As a result, the user will be able to maintain a harder erection.
This pump allows vacuum levels from 1 Hg. to 15 Hg, including 10 vacuum presets. The product has a 1-year warranty and the company provides free lifetime software updates.
DP-4000 can be described as an old product when compared to similar electronic air pumps that have just been released recently. This product requires the user to connect it directly to the computer in order to manipulate the settings of the machine. The last software update for this product was in 2012 so it could be outdated.

I have multiple manual pumps at home. But DP-4000 beats them all. Getting my own machine is like taking the plunge. It is pricey, but when I got my hands on it, I was able to tell myself “I wish I had gotten this sooner”.
Not recommended for someone who plans on using it while traveling, though. It is smaller than expected but still, it would be a hassle when you have to explain to the security what that device is for.
I am using a MAC, so I had to download a virtual machine to run a windows program. It’s not very convenient but I am glad the program was set up quickly.
Compared with a manual pump, I would always choose my DP-4000. The fact that you can program your pumping session is enough to choose it over a manual pump.
I have my DP-4000 since 2012. For 5 years, I gained 1.5 inches from regularly using this product. It took me about 2 years to create the pattern that I stick with until now. It takes trial and error to set up what pattern suits you.
That can be hard for some, but if you are as determined as I am you will be able to find the perfect pump that suits your lifestyle.
It’s funny how this product is so noisy I could actually wake the neighbors when doing it during the night. Now my sessions depend on when my neighbor is awake or asleep. I decided getting some soundproofing ideas just to be able to enhance my size. I am still about to find out whether this product works for me.
This product is very powerful that you can easily have a doughnut. I was using it for almost 3 weeks already when I figured maybe I could try to see my limit. I guess I pumped for too long using a high pressure.
I was so shocked that my penis got swollen so easily. I was traumatized at first, so I stopped using this for a while. I started a new session with it again just recently and only used the low pressure.
I have been trying to gain for about a decade now, and I can say that I have tried all the other cheap alternatives out there. DP-4000 poses a risk because of its huge price. But the cheap ones don’t really work well for me. This automatic pump is not very tedious to use. It is noisy but worth it.
The complete system includes the following items:
The pump is currently available for purchase on their official website, eBay, and Alibaba for 469.00 USD each.
CTC does not specify any money back guarantee, but their eBay store states that they do not accept returns.
DP-4000 proved effective for some men. However, because it is expensive, outdated and uses old technology, we recommend using other option for pumping. See our article for a complete list of recommended pumping tools.
The following are old reviews for DP-4000.
I have my own DP-4000 but I can’t get to set it up in my laptop, although I was able to get it working using my old computer from before. I can’t figure it out, but I can’t access it using any laptop.
I am able to see the program from the software, and it seems fine from the laptop, but only the machine doesn’t seem to be able to read the program when connected to a laptop. This is still not fixed and the customer support is not very helpful with this.
If you have the money to buy a product that is worth it, I’d say go with DP-4000. It works, and I gained about 2” in girth and length after using it for 2 years now.
Aside from pumping, I also have Jelqing and stretching routines. You get what the website promises – it is automatic, with programmable pressure and timing. I use it all night in low pressure. During the day-time, I have a short routine for using it in high pressure.
I have been trying to hide doing my PE’s from my wife but it is impossible when I am using DP-4000. It is just too noisy that I can’t do it whenever she is around.
I bought a manual pump to replace it and now I am back on track. It’s just a waste seeing it lying around and not being used.
