P Shot London vs Viagra – Which Works Better and Lasts Longer?
Mark is 52. He runs his own business, stays active, and by most measures is in good health. But for the past two years, he has quietly struggled with erectile dysfunction. His GP prescribed sildenafil — the generic form of Viagra — and it worked, up to a point. He hated planning around it. He disliked the headaches. And he wanted a solution that did not come in a foil blister pack he kept hidden in his desk drawer.
After researching his options, Mark came across the P Shot. He had never heard of it before. Within six months, he no longer needed the tablets.
His story is not unusual. Across the UK, more men are weighing up oral medication against injectable treatments for erectile dysfunction. This article examines both options objectively — what they are, how they work, what the evidence suggests, and which might be more suitable for different individuals.
What Is Viagra and How Does It Work?
Viagra — or sildenafil, its generic name — belongs to a class of drugs called PDE5 inhibitors. It works by relaxing the smooth muscle in the walls of blood vessels inside the penis. This increases blood flow during sexual arousal and helps produce an erection.
The NHS lists sildenafil as a first-line treatment for erectile dysfunction. NICE (the National Institute for Health and Care Excellence) includes it in its clinical guidelines for managing ED, and it is available on NHS prescription in most circumstances.
Sildenafil is effective. Large-scale clinical trials show it works in around 70% of men with erectile dysfunction. It is well-researched, affordable, and widely prescribed. For many men, it does exactly what it is supposed to do.
But it has clear limitations.
The Limitations of Oral ED Medication
Viagra is not a treatment. It is a temporary aid. Take the tablet, wait 30 to 60 minutes, use it within a four-hour window. Miss the timing and the opportunity passes. Take it after a heavy meal and absorption slows. Drink too much alcohol and it becomes unreliable.
Common side effects include headaches, facial flushing, indigestion, and nasal congestion. Less common but more serious effects include a sudden drop in blood pressure, particularly when combined with nitrate medications used for heart conditions. Men on certain cardiac drugs cannot take PDE5 inhibitors at all.
There is also the psychological dimension. Erectile dysfunction is often tied to anxiety. Relying on a tablet — and the precise timing it demands — can reinforce rather than reduce performance pressure.
And critically, sildenafil does nothing to address the underlying causes of erectile dysfunction. It manages the symptom. It does not improve penile tissue health, stimulate new blood vessel growth, or restore natural function. When the tablet wears off, nothing has changed.
What Is the P Shot?
The P Shot — short for Priapus Shot — is a non-surgical treatment that uses platelet-rich plasma (PRP) derived from the patient’s own blood. It is injected directly into specific areas of the penis using a fine needle.
The procedure follows a straightforward process. A small amount of blood is drawn, typically from the arm. That blood is spun in a centrifuge to separate the plasma from red blood cells. The resulting PRP is rich in growth factors — naturally occurring proteins that play a role in tissue repair and regeneration. This concentrated plasma is then injected into the penile tissue.
The goal is not to create an immediate chemical response the way Viagra does. The P Shot works by stimulating the body’s own repair mechanisms. Growth factors from PRP encourage the formation of new blood vessels (a process called angiogenesis) and promote the regeneration of smooth muscle tissue. Over weeks and months, this can improve the underlying vascular health of the penis.
The treatment takes roughly 45 minutes from start to finish. A topical anaesthetic is applied beforehand, so discomfort is minimal. There is no general anaesthetic, no incision, and no significant downtime.
P Shot London: What the Evidence Says
The scientific literature on PRP for erectile dysfunction is growing. A 2021 systematic review published in Sexual Medicine Reviews examined multiple studies on PRP for ED and found evidence of improvements in erectile function scores, particularly in men with mild to moderate dysfunction. The researchers concluded that PRP showed promise as a regenerative option, though they called for larger randomised controlled trials.
A 2020 study in Andrology found that PRP injection led to statistically significant improvements in the International Index of Erectile Function (IIEF) scores in men who had not responded adequately to oral medication. This is important: the P Shot may offer benefit precisely in the group that finds Viagra insufficient or unsuitable.
Research published by institutions including the Cleveland Clinic and various European urology departments has also noted improvements in penile sensitivity, sexual confidence, and In some cases, modest gains in girth due to tissue regeneration. These changes are not cosmetic additions — they reflect genuine tissue-level improvement.
The evidence base is not yet as deep as that for sildenafil, which has decades of large-scale trial data behind it. But the trajectory is positive, and the mechanism is well understood from PRP’s established use in orthopaedics, dermatology, and wound healing.
How Does P Shot Treatment Compare to Viagra in Practice?
The honest answer is that they do different things.
Viagra produces a reliable, predictable effect on demand. If you need a result tonight, sildenafil is still the most dependable option for most men.
The P Shot does not produce an immediate effect after a single session. Most men notice gradual improvements over four to twelve weeks. Some report meaningful changes after a second or third treatment. The improvement, when it comes, reflects an actual change in tissue and vascular function — not a pharmacological override of the body’s current state.
This distinction matters. Men who respond well to the P Shot often report:
- Erections that feel more natural and less dependent on planning
- Improved sensitivity
- Greater confidence in sexual situations
- Reduced reliance on, or complete discontinuation of, oral medication
For men with vascular or neurological causes of erectile dysfunction, the P Shot addresses the root issue rather than masking it. For men whose ED is entirely psychological in origin, the results may be less predictable.
Who Is a Good Candidate for the Priapus Shot?
The P Shot tends to produce the best outcomes in men who:
- Have mild to moderate erectile dysfunction with a vascular component
- Find oral medication unreliable, inconvenient, or poorly tolerated
- Cannot take PDE5 inhibitors due to cardiac medication or other contraindications
- Want to reduce or stop their dependence on tablets
- Are interested in a longer-term approach rather than an on-demand fix
Men with severe erectile dysfunction linked to significant nerve damage — such as after radical prostatectomy — may see more limited results, though some studies have shown benefit even in this group.
A full medical consultation is essential before any P Shot treatment. Erectile dysfunction can be an early sign of cardiovascular disease, diabetes, or hormonal imbalance. Any reputable clinic will ensure these are properly assessed first.
Priapus Shot Price and Cost Considerations in the UK
The priapus shot price in the UK varies depending on the provider, the number of sessions, and whether additional treatments such as low-intensity shockwave therapy are included in a combination protocol.
In London, a single P Shot session typically ranges from £1500 to £2,500. Clinics offering male enlargement injections cost UK-wide vary considerably, so it pays to compare experience, qualifications, and what is included in the price.
Sildenafil on prescription costs very little — sometimes as little as £1.50 per tablet on the NHS. The financial comparison is stark. But Viagra is a recurring cost with no endpoint. Men who use the tablet regularly for years spend more over time than a course of PRP treatment. And Viagra does not improve the underlying condition.
What to Expect: P Shot Before and After
P shot before and after outcomes vary between individuals, but the pattern reported most consistently includes improved erectile firmness, increased sensitivity, and a reduction in the time needed to achieve an erection. Some men also note an improvement in the quality of their orgasms.
In terms of size, P shot before and after comparisons sometimes show modest gains in girth as new tissue develops. These changes are not dramatic and should not be the primary reason for choosing the treatment. The main therapeutic goal is improved erectile function and sexual health.
Realistic expectations matter. The P Shot is not a guaranteed cure, and results depend on individual biology, the severity of the underlying condition, and general health. Most practitioners recommend a course of two to three treatments for optimal results, spaced several weeks apart.
Is the P Shot Safe?
Because the treatment uses the patient’s own blood, the risk of allergic reaction or immune rejection is effectively zero. There is no foreign substance being introduced to the body.
The most common side effects are mild and temporary: slight bruising or swelling at the injection site, occasional tenderness lasting a few days. Serious complications are rare when the procedure is performed by a qualified medical professional in a clinical setting.
This is why practitioner qualification matters significantly when seeking P Shot London treatment. PRP therapy requires proper blood handling, sterile technique, and an understanding of penile anatomy. This is not a treatment to seek from a non-medical aesthetics provider.
At pshots.co.uk, treatments are led by Dr Syed Nadeem Abbas — MBBS, MRCS (RCS Edinburgh), MRCGP, and MSc in Aesthetic Plastic Surgery with Distinction from Queen Mary University London, with clinical training at Cambridge, Oxford, and the Royal London Hospital — operating from a Harley Street clinic.
Combining Treatments: A Note on Protocols
Some clinics now use the P Shot in combination with low-intensity extracorporeal shockwave therapy (Li-ESWT) or vacuum erection devices as part of a broader penile rejuvenation protocol. Early data suggest that combination approaches may outperform either treatment used in isolation.
The penile injection growth seen with PRP may also be enhanced when the treatment is paired with appropriate lifestyle changes — addressing weight, blood pressure, smoking, and alcohol intake. Erectile function is closely linked to cardiovascular health. No injection or tablet compensates fully for poor vascular health upstream.
The Verdict: Which Works Better?
Viagra works faster and more predictably in the short term. For men who need reliable, on-demand support, it remains a highly effective option and carries decades of clinical backing.
The P Shot works differently. It does not produce an immediate pharmaceutical effect. It works by improving tissue health over time. Men who want to address the underlying issue — not just manage the symptom — and who commit to a gradual process gain something from the P Shot that Viagra cannot: it improves natural function and sustains it without continued medication.
They are not mutually exclusive. Some men use oral medication during the weeks following a P Shot session, then find they need it less or not at all as the tissue-level improvements take hold.
The right choice depends on the individual — their health history, their goals, how their current treatment is working, and what they want from their sexual health long-term.
A Final Thought
NHS estimates show erectile dysfunction affects roughly one in five men in the UK, and experts believe the true figure runs higher because men rarely seek help. The conversation around treatment is slowly becoming more open, and the options available have expanded meaningfully in recent years.
Viagra was a revolution when it arrived. PRP therapy may represent the next step — a move from symptom management to genuine regeneration.
So the question worth asking is this: are you looking for a tablet that helps tonight, or a treatment that might mean you no longer need the tablet at all?
