P (Priapus Shot)

What Does the P Shot Actually Do? A Plain-English Explanation

Nobody talks about it. That is the honest truth. Men discuss back pain, knee injuries, and cholesterol levels without hesitation. Erectile health? That stays private — even when it quietly affects daily life, relationships, and self-confidence.

James was 44 when he first heard the phrase “P shot” from a colleague. The conversation lasted thirty seconds. Nobody followed up. He spent the next three months researching it alone, sifting through contradictory claims and confusing medical jargon.

He deserved better information. So do you. This article cuts through the noise and explains, in plain English, exactly what the P shot is and what the science actually says.

What Is the P Shot?

The P shot — short for the Priapus shot — is a medical treatment for men. It uses the patient’s own blood to create a substance called platelet-rich plasma, or PRP. That PRP gets injected directly into specific areas of the penis.

The name comes from Priapus, the Greek god associated with male fertility. The treatment itself was developed in the United States and has since gained significant interest across the UK and Europe.

The priapus shot does not use synthetic chemicals. It does not involve surgery. The entire process relies on growth factors found naturally in your own blood.

How Does the P Shot Actually Work?

To understand the p shot treatment, you first need to understand PRP.

What Is PRP?

Your blood contains red cells, white cells, platelets, and plasma. Platelets carry growth factors — tiny proteins that repair tissue and stimulate new cell growth. PRP is simply plasma with a concentrated amount of those platelets.

To make PRP, a small amount of blood gets drawn from your arm. A machine called a centrifuge spins it at high speed. This separates the components. The platelet-rich layer gets collected and prepared for injection.

Where Does the Injection Go?

The p injection targets two main areas: the corpus cavernosum (the spongy tissue that fills with blood during an erection) and the glans (the tip of the penis). A numbing cream gets applied beforehand. Most men report little to no discomfort during the procedure.

The whole appointment typically takes under an hour.

What Does the P Shot Claim to Do?

Claims vary across clinics and websites. It is important to separate what the evidence supports from what remains under investigation.

The p shot aims to:

Improve blood flow to penile tissue
Stimulate the growth of new blood vessels
Encourage collagen production
Support nerve sensitivity
Potentially improve erectile function

Some practitioners and patients also report changes in penile size after treatment. This is where the term male enlargement injections enters the conversation. However, it is important to approach size-related claims with realistic expectations. Results vary significantly between individuals.

What Does the Evidence Say?

The NHS does not currently offer the P shot as a standard treatment. NICE (the National Institute for Health and Care Excellence) has not issued formal guidance specifically on PRP for erectile dysfunction at the time of writing. That does not mean the treatment lacks evidence — it means the research is still developing.

Several peer-reviewed studies have explored PRP for erectile dysfunction. A 2020 study published in Sexual Medicine Reviews reviewed the existing clinical data. Researchers found that PRP showed promising early results for men with mild to moderate erectile dysfunction. However, larger randomised controlled trials are still needed to confirm long-term outcomes.

For men exploring options beyond standard medication such as sildenafil (Viagra) or tadalafil (Cialis), the p shot offers a different mechanism of action. It targets tissue repair rather than simply increasing blood flow in the short term.

Who Might Benefit from the P Shot?

The p shot is not suitable for everyone. However, certain groups of men tend to explore it most often.

Men with Erectile Dysfunction

Erectile dysfunction affects around 52% of men between the ages of 40 and 70 to some degree, according to established research. For men who have not responded well to oral medications, or who prefer a non-pharmaceutical approach, the priapus shot presents an alternative worth discussing with a qualified clinician.

Men Recovering from Prostate Surgery

Some men experience erectile difficulties following prostate cancer treatment. Early research suggests PRP may support tissue recovery in this group, though this remains an area of ongoing investigation.

Men Seeking Sensitivity Improvements

Reduced penile sensitivity can affect sexual satisfaction. Some men report improved sensitivity following p shot treatment. Again, individual results vary.

What to Expect: P Shot Before and After

Understanding the realistic p shot before and after picture helps set the right expectations.

Before the procedure: A consultation takes place first. Medical history gets reviewed. Blood pressure and general health are assessed. The clinician explains the process in full.

During the procedure: Blood is drawn. PRP is prepared. The penis receives a topical anaesthetic. The injections follow — typically taking just a few minutes.

After the procedure: Mild swelling or bruising may occur. Most men return to normal activities the same day. Sexual activity is usually advised to resume after 24 to 48 hours.

In the weeks that follow: PRP works gradually. Growth factors stimulate tissue changes over time. Most practitioners suggest allowing four to twelve weeks before assessing results. Some men choose a second treatment to enhance outcomes.

The p-shot before and after experience differs between patients. Some report noticeable improvements in erection quality within weeks. Others notice more subtle changes over a longer period.

Is the P Shot Worth the Price?

That depends on what you are comparing it to. Oral medication for erectile dysfunction costs relatively little per dose. Surgery costs a great deal more. The P shot sits somewhere between the two — in both price and level of intervention.

Across the UK, most men pay between £800 and £2,000 per session. In London, particularly at specialist clinics in areas like Harley Street, prices lean toward the higher end. That is not unusual for any specialist private medical treatment in central London.

Priapus shot pricing should always be transparent. A reputable clinic will tell you upfront what the fee covers — consultation, blood draw, PRP preparation, the injection, and follow-up appointments. Watch out for headline prices that exclude key elements.

Male enlargement injections cost more when paired with additional treatments. Some men choose to combine the P shot with shockwave therapy, which adds to the total but may improve overall outcomes.

Above all, do not let price be the only factor. The qualifications of the person holding the needle matter far more than saving a few hundred pounds.

Is the P Shot Safe?

Because the P shot uses your own blood, the risk of allergic reaction is extremely low. There is no foreign substance introduced into the body.

Common side effects include temporary swelling, mild bruising, and minor discomfort at the injection site. Serious complications are rare but can include infection if the procedure is not performed under proper sterile conditions.

Choosing a medically qualified practitioner matters enormously. The procedure should only take place in a regulated clinical environment — not a beauty salon or non-medical setting.

What Makes a Good P Shot Clinic?

Not all providers are equal. When looking for p shot London options, consider the following.

The practitioner should hold recognised medical qualifications. They should complete a full medical consultation before the procedure. The clinic should use medical-grade PRP preparation equipment. Aftercare and follow-up should be included in the service.

At drsnaclinic.com, Dr Syed Nadeem Abbas (MBBS, MRCS RCS Edinburgh, MRCGP, MSc Aesthetic Plastic Surgery with Distinction — Queen Mary University London) leads all treatments from the clinic’s Harley Street base. His background spans training at Cambridge, Oxford, and the Royal London Hospital, which positions him to assess each patient’s suitability thoroughly and advise on realistic outcomes.

The P Shot vs Other Treatments

How does penile injection growth therapy compare to other options?

Oral medications such as sildenafil work by increasing blood flow temporarily. They do not repair underlying tissue damage. The P shot targets the tissue itself.

Penile pumps create a vacuum to draw blood into the penis. They can be effective but require use before each sexual encounter.

Penile implants involve surgery. They carry surgical risks and a longer recovery period. Most men explore all non-surgical options first.

Shockwave therapy is another non-invasive option that uses sound waves to stimulate blood vessel growth. Some clinics combine shockwave therapy with the priapus shot for a more comprehensive approach.

Common Questions Men Ask

Does the P shot make the penis bigger?

Some men report a modest increase in size, particularly in girth. However, the primary purpose of the priapus shot is functional improvement — better erections, improved sensitivity, enhanced blood flow. It is not a guaranteed enlargement treatment.

How many sessions do I need?

Many practitioners recommend starting with one session and reviewing after eight to twelve weeks. A second session may follow depending on the outcome.

Is it available on the NHS?

Not currently. The P shot falls outside standard NHS provision. It is available through private clinics across the UK, including several in London.

How long do results last?

Results typically last between twelve and eighteen months. Some men return annually for a maintenance session.

Summary

The P shot is a legitimate medical procedure with a growing body of evidence behind it. It is not a miracle cure. It will not work identically for every man. However, for men dealing with erectile dysfunction, reduced sensitivity, or post-surgical recovery, it offers a non-surgical option grounded in the body’s own biology.

The key is finding a qualified medical professional who takes time to assess your situation, explain the process clearly, and set honest expectations about what the treatment can realistically achieve.

Marcus, the man at the start of this article, eventually booked a consultation. He did not walk away with a guaranteed outcome. He walked away with clarity — a full understanding of what the treatment involved, what it might do, and what it would not do. That, in itself, made all the difference.
