Quick answer: The P-Shot (Priapus Shot) is a treatment that uses your own platelet-rich plasma (PRP), injected into the penis, with the aim of improving erectile function. The evidence is mixed. Some small studies show promise, but at least one placebo-controlled trial found no significant benefit. It should never replace seeing a GP.

If you’re looking into the P-Shot in the UK, you probably want the honest picture. Does it actually work for erectile dysfunction (ED)? What does the science really say? And is it worth your money?

This guide gives you a calm, clear answer. We’ll explain what the P-Shot is, how it works, and what the research shows, good and bad. We’ll also be straight about what it cannot do.

Most importantly, we’ll explain why anyone with ED should speak to a GP first. ED can be an early warning sign of serious health problems, and that matters more than any single treatment.

What is the P-Shot?

The P-Shot, also called the Priapus Shot, is a non-surgical treatment for erectile dysfunction and other intimate health concerns. It uses platelet-rich plasma (PRP) taken from your own blood.

PRP is used across medicine, from sports injuries to skin treatments. The idea is that platelets contain growth factors that may help repair and regenerate tissue.

When applied to the penis, the aim is to support blood flow, sensation, and firmer erections. Because the P-Shot uses your own blood, it’s often described as a natural treatment.

That said, “natural” doesn’t automatically mean “proven.” As you’ll see below, the evidence for the P-Shot is still developing.

How does the P-Shot work?

The P-Shot for erectile dysfunction follows a simple, three-step process. It usually takes around 30 minutes.

1. Blood is drawn. A small blood sample is taken from your arm, much like a routine blood test.

2. The blood is spun. The sample is placed in a centrifuge, which spins fast to separate the platelet-rich plasma from the rest of the blood.

3. The PRP is injected. The concentrated PRP is then injected into specific areas of the penis, using topical or local anaesthetic to keep you comfortable.

The theory is that the growth factors in PRP encourage new tissue and new blood vessels to form. This process is sometimes called neovascularisation.

Downtime is minimal. Most men return to normal activity straight away. Some notice temporary swelling or light bruising for a day or two.

At ErectiFill, a first course of the P-Shot usually involves two sessions about one month apart, followed by a top-up every 12 to 18 months. You can learn more about our P-Shot treatment and discuss whether it suits you.

Does the P-Shot work for ED? An honest look at the evidence

Here’s the part that matters most, and where honesty counts.

The P-Shot is a relatively new treatment, and the research is limited. The overall picture is genuinely mixed.

Some small studies show positive signs. A number of early, small-scale studies have reported improvements in erectile function after PRP injections. These findings are encouraging, but small studies have limits. Without a placebo group, it’s hard to know how much of the benefit is real and how much is the placebo effect.

A stronger study found no clear benefit. A placebo-controlled trial involving more than 60 men compared PRP injections against a placebo. It found no statistically significant difference between the two groups. In plain English, the men who received PRP did not clearly do better than those who received a dummy treatment.

Placebo-controlled trials are considered a higher standard of evidence, because they help rule out the placebo effect. So this result is important, and we won’t pretend otherwise.

What this means for you. The P-Shot may help some men, but the science does not currently prove it cures or reliably treats ED. Anyone who promises guaranteed results is overstating what the evidence can support.

If you’re weighing up a PRP injection for erectile dysfunction, go in with realistic expectations. Treat it as an option that some men find helpful, not a certain fix.

What the P-Shot cannot do

Being clear about limits is just as important as listing benefits.

The P-Shot does not increase penis size. If you see claims that PRP injections make the penis permanently bigger, be cautious. The evidence does not support that.

The P-Shot is also not a substitute for medical care. It doesn’t treat the underlying health conditions that often cause ED, which brings us to the most important point in this article.

When to see a GP about erectile dysfunction

If you have ED, please see a GP before anything else. This isn’t a formality. It could protect your long-term health.

ED is not only a bedroom problem. It can be an early warning sign of serious conditions, including:

• Cardiovascular disease. The blood vessels in the penis are small. They can show problems with blood flow before symptoms appear elsewhere, sometimes years before a heart attack or stroke.

• Diabetes. ED is a common early symptom of type 2 diabetes, which can damage nerves and blood vessels.

• High blood pressure and hormonal imbalances. Both can contribute to ED and both need proper medical assessment.

There are psychological causes too, such as stress, anxiety, depression, and relationship worries. A GP can help you separate physical causes from psychological ones.

A GP can check your blood pressure, run blood tests, review your medications, and refer you if needed. In short, they treat the whole picture, not just the symptom. No cosmetic or intimate-health treatment should ever come before that check.

Where the P-Shot fits: the ErectiFill Magnum XL Package

If you’ve seen a GP and you’re exploring intimate-health treatments, the P-Shot may form part of a broader plan rather than a standalone fix.

At ErectiFill, the P-Shot is included in the ErectiFill Magnum XL Package. This combination treatment brings together three procedures in one appointment:

• Penis filler (ErectiFill Exclusive) to add erect and non-erect girth and non-erect length using hyaluronic acid-based dermal filler.

• The P-Shot (Priapus Shot®) using your own PRP, with the aim of supporting blood flow and sensation.

• Bocox®, targeted botulinum toxin injections designed to relax smooth muscle tissue and support blood flow.

The package is non-surgical, minimally invasive, and carried out by experienced doctors. Bought separately, the three treatments would cost £3,149. As a package, it’s £2,750, saving £399.

Results vary from person to person. The filler produces an immediate visual change, while any benefit from the P-Shot and Bocox® tends to develop over the following weeks. As always, a doctor can give you honest, personalised advice on whether this is right for you.

Frequently asked questions

Does the P-Shot cure erectile dysfunction?

No. The P-Shot does not cure ED. The evidence is mixed, and a placebo-controlled trial of more than 60 men found no significant difference versus a placebo. Some men report improvements, but results cannot be guaranteed. Always see a GP first, as ED can signal cardiovascular disease or diabetes.

How much does the P-Shot cost in the UK?

At ErectiFill, the P-Shot is £999 for a single session or £1,800 for two sessions. It is also included in the Magnum XL Package at £2,750, which combines the P-Shot with penis filler and Bocox®. A consultation with a GMC-registered doctor can help you decide what suits you.

Is the P-Shot safe?

The P-Shot uses your own platelet-rich plasma, so the risk of reaction is low. Side effects are usually mild, such as temporary swelling or bruising for one to two days. All ErectiFill treatments are carried out by qualified doctors. A consultation will assess whether it’s suitable for you.

Does the P-Shot increase penis size?

No. The P-Shot does not reliably increase penis size, and you should be cautious of any claim that it does. Its aim is to support erectile function and sensation using PRP. If added size is your goal, discuss other options, such as penis filler, with a doctor first.

How long does it take to recover after the P-Shot?

Recovery is quick. The procedure takes around 30 minutes, and most men return to normal activity straight away. Some experience mild swelling or bruising for a day or two. Any benefit to erectile function tends to develop gradually over the following weeks.
