What Is The P-Shot®? Does It Actually Work?

The P-Shot®, also known as the Priapus Shot, is a medical procedure that involves injecting platelet-rich plasma (PRP) into the penis. The goal of this treatment is to enhance sexual performance, increase penis size, and treat erectile dysfunction (ED). But does it actually work? Let’s take a closer look at the science behind the P-Shot®.

The procedure provides improvements in sexual performance to men, especially if you’ve lost penis function because of prostate cancer, have an enlarged prostate, after having surgery, as a side effect of a prescription drug, or from diabetes.

How does it work?

Is a non-surgical, minimally invasive procedure that involves drawing a small amount of blood from the patient’s arm. The blood is then spun in a centrifuge to separate the platelets, which contain growth factors, from the rest of the blood components. The resulting PRP is then injected into specific areas of the penis.

The growth factors in the PRP are believed to stimulate the growth of new blood vessels and tissue in the penis, leading to improved sexual function and potentially increased penis size.

How Long Does the P-Shot® Last?

Platelet rich plasma will begin to kick in and start working at about 2-3 weeks after the injection and then gradual improvements should occur up to 3-4 months later. Every case of erectile dysfunction is different so responses vary.

Does It Actually Work?


While there are many anecdotal reports of the P-Shot® improving sexual function and penis size, the scientific evidence is limited. There have been a few small studies on the effectiveness of PRP injections for ED, with mixed results.

One study published in the Journal of Sexual Medicine in 2017 found that PRP injections improved erectile function in men with ED who had not responded to other treatments. However, another study published in the same journal in 2018 found no significant improvement in erectile function after PRP injections.

As for claims of increased penis size, there is little scientific evidence to support these claims. While PRP injections may lead to some temporary swelling or inflammation, there is no evidence that they actually increase penis size in the long term.

It’s also worth noting that the P-Shot® is not a cure for ED or other underlying medical conditions that may be contributing to sexual dysfunction. It’s important for patients to work with a qualified healthcare provider to address any underlying medical issues and determine the best treatment approach.

How much does It Increase Size?

While the injection of platelet-rich plasma into the penis may lead to some temporary swelling or inflammation, there is no evidence that it can lead to a permanent increase in penis size. The P-Shot® is primarily marketed as a treatment for sexual dysfunction, including erectile dysfunction (ED), and may improve sexual function in some men.

However, it’s important for patients to approach this treatment with realistic expectations and work with a qualified healthcare provider to determine the best course of action for their individual needs.

Who is it made for?

P-Shot® is primarily made for men

The P-Shot® is primarily made for men who are experiencing sexual dysfunction, such as erectile dysfunction (ED), premature ejaculation, or a decrease in sexual desire. It may also be of interest to men who are seeking non-surgical options to improve sexual performance or potentially increase penis size. However, it’s important to note that the P-Shot® is not a one-size-fits-all solution and may not be appropriate for everyone. Patients should discuss their individual medical history and concerns with a qualified healthcare provider to determine if this treatment is right for them.

It combats erectile dysfunction due to:
  • Prostate issues
  • Prescription drug side effects
  • Hypertension
  • Diabetes

Are there any risks or side effects?

Like any medical procedure, the P-Shot® does come with some risks and potential side effects. These may include pain, swelling, bruising, and infection at the injection site. There is also a risk of priapism, a prolonged erection that can be painful and requires medical attention.

Patients should only undergo the P-Shot® or any medical procedure under the supervision of a qualified healthcare provider who can provide appropriate follow-up care.


In conclusion, while the P-Shot® may show promise for improving sexual function and treating ED, the scientific evidence is limited and more research is needed. Patients should approach this treatment with caution and work with a qualified healthcare provider to determine the best course of action for their individual needs.
