Erectile dysfunction affects millions of men across the UK, yet most never talk about it openly — not to their GP, not to their partner, and certainly not to a friend over a pint. That silence keeps men stuck in a cycle of frustration, damaged confidence, and treatments that barely scratch the surface. If you have tried pills that worked for a while and then stopped, or if you simply want something that actually addresses the problem rather than masking it for four to six hours, you are probably already researching what else exists. Two names come up again and again: the P shot treatment and shockwave therapy. Both are non-surgical.

Both are drug-free. Both target the vascular root of ED rather than the symptoms. But they work in entirely different ways — and choosing the wrong one could mean wasting time and money on a treatment that was never the right fit for your situation. This article breaks down exactly how each option works, who benefits most, what results look like over time, and how combining them could outperform either treatment alone. Everything you read here draws directly from verified clinical information published by Dr SNA Clinic London, a CQC-regulated practice on Wimpole Street, Marylebone, led by GMC-registered physician Dr Syed Nadeem Abbas.

What Is the P-Shot (Priapus Shot) and How Does It Work?

The Priapus shot — commonly written as the P shot or P-shot — uses platelet-rich plasma (PRP) drawn from your own blood. Dr Abbas draws a small blood sample from your arm, places it in a medical-grade centrifuge, and processes it using a dual-spin protocol that concentrates platelets to a significantly higher level than standard single-spin methods. He then injects the concentrated plasma directly into penile tissue using ultra-fine needles.

The Biology Behind the P Injection

The growth factors inside PRP trigger a biological chain reaction. Your body starts forming new capillary networks — a process called angiogenesis — which delivers more oxygenated blood to the erectile chambers. Simultaneously, PRP supports nerve fibre renewal (neurogenesis) and stimulates collagen and elastin production inside the corpora cavernosa. The result, in suitable candidates, is improved firmness, better sensitivity, and stronger sustained erections.

This is precisely why men searching for penile injection growth outcomes tend to respond well to the priapus shot: it works at a tissue level, not just a surface level.

What Is Shockwave Therapy and How Does It Differ?

Low-intensity shockwave therapy (LI-ESWT) delivers acoustic sound waves through the skin into penile tissue. Those waves create micro-trauma at a cellular level, which prompts the body to send healing signals and form new blood vessels. Like PRP, shockwave therapy targets the vascular component of ED. Unlike the p-shot, it introduces no biological material — it simply stimulates your tissue mechanically.

Key Differences at a Glance

Shockwave therapy typically requires multiple sessions (often six or more), whereas a single p-shot session can produce meaningful results. Shockwave results can last up to two years in some patients; P shot before and after data suggests the Priapus shot sustains results for 12 months or longer on average. Shockwave therapy costs around £500 per session in the UK. The Priapus shot price at Dr SNA Clinic starts from £1,250 for a standard session.

Who Responds Best to the P-Shot vs Shockwave Therapy?

This is where most comparison articles fall short. They list features without addressing patient fit. Dr Abbas explains it clearly at consultation — and it is worth understanding before you book anything.

Ideal Candidates for the Priapus Shot

Men with mild to moderate vascular-related erectile dysfunction tend to respond most consistently to P shot treatment. The penis shot also suits men who have had limited success with PDE5 inhibitors (Viagra or Cialis) or who prefer to avoid long-term pharmaceutical dependence. It works well for patients managing Peronei’s disease, reduced sensation, or post-surgical changes following prostate treatment.

If you are looking at male enlargement injections cost UK and wondering whether the priapus shot qualifies, the answer is yes — PRP stimulates tissue quality and blood flow in the treated area, and some patients experience improvements in girth as collagen production increases. Results, however, vary between individuals, and Dr Abbas discusses this candidly at consultation.

When Shockwave Alone May Suit You Better

Shockwave therapy suits men who respond well to mechanical stimulation and prefer a non-injection approach. It requires no needles, no blood draw, and no biological processing. For milder presentations of ED where the vascular issue is relatively contained, shockwave alone can produce solid results — particularly when patients commit to the full course of sessions.

Why Combining Both Treatments Delivers Stronger Outcomes

Dr SNA Clinic London offers an Enhanced P-Shot + Shockwave package at £1,350, combining both treatments in a single appointment. This is not simply a bundle for value — there is a clinical rationale behind it.

The Synergistic Effect

Shockwave therapy primes penile tissue by creating micro-stimulation that increases cellular uptake. When Dr Abbas then administers the P-shot, the growth factors have a more receptive environment to act within. New blood vessel formation accelerates, nerve signals strengthen faster, and tissue repair begins earlier. Verified patient reviews on Google and Trustpilot describe the combined treatment as the turning point after years of frustration.

The P-shot before and after experience for combined treatment patients shows faster onset of results and greater improvements in erection quality compared to either treatment in isolation. Dr Abbas holds a 4.9-star rating across verified patient reviews — a reflection of both clinical outcomes and the honest approach he takes at every consultation.

Pricing, Timing, and What Each Appointment Involves

Understanding what you actually pay for — and what the appointment looks like — removes much of the anxiety men feel before booking.

Standard P-Shot: £1,250

Dr SNA Clinic delivers the standard P-shot for £1,250 (reduced from £1,550). This includes dual-spin PRP processing, topical numbing or a penile nerve block based on your preference, injections performed personally by Dr Abbas, and both a six-week and twelve-week follow-up consultation. There are no hidden charges.

Enhanced P-Shot + Shockwave: £1,350

The enhanced package combines the full p-shot protocol with low-intensity shockwave therapy in the same appointment. The cost is £1,350 (reduced from £1,750). Dr SNA Clinic considers this the most recommended option where vascular factors contribute significantly to ED.

What Happens During the Appointment

Dr Abbas draws a small blood sample from your arm. He processes it on-site using a medical-grade centrifuge for approximately 15 minutes. He then extracts the concentrated plasma and administers it via ultra-fine needles — typically four to five placements — into targeted penile tissue. The full appointment runs 30 to 40 minutes. Most men return to normal daily activity, including driving and desk-based work, immediately afterwards. Dr Abbas advises abstaining from sexual activity for four to five days to allow the treated tissue to settle.

What Do P-Shot Before and After Results Actually Look Like?

The timeline matters because men often expect immediate changes. The p-shot works gradually, which reflects how biological repair actually functions.

Week 1–2: The Settling Phase

The treated area settles. Some patients notice a mild increase in sensitivity. Most men see no visible signs that a procedure took place.

Around Week 4: First Changes Emerge

Many patients report stronger morning erections and noticeably increased sensitivity. The angiogenic process actively progresses. Dr Abbas reviews progress at the six-week follow-up.

Weeks 8–12: Peak Results

This is when the most significant p-shot before and after changes become apparent. Patients report stronger erections, improved firmness, heightened sensation, and greater confidence. Men with Peyronie’s disease may notice reduced curvature or discomfort during this period.

Beyond 12 Months

Results persist for 12 months or longer on average. Many men choose an annual maintenance session to sustain their outcomes. Visit the official Dr SNA Clinic website to read verified patient accounts from men who completed the full treatment journey.

Why Choose Dr SNA Clinic for Your P-Shot in London?

Not every clinic offering a Priapus shot London delivers the same standard of care. The difference lies in the physician, the protocol, and the clinical environment.

Dr Syed Nadeem Abbas holds an MBBS, MRCSEd, and an MSc in Aesthetic Plastic Surgery with Distinction from Queen Mary University of London. He built six years of clinical experience in Trauma and Orthopaedics at NHS hospitals including Cambridge and Oxford. He holds specialist P-Shot certification from the American Cellular Medical Association — one of a small number of UK-based physicians with formal accreditation in this specific procedure.

Every P shot UK patient at Dr SNA Clinic receives treatment from Dr Abbas personally. He does not delegate the procedure to nurses or junior practitioners. He uses a dual-spin centrifuge protocol that produces a higher platelet concentration than standard methods. The clinic operates under CQC regulation and holds full medical indemnity insurance.

0% finance is available for patients who prefer to spread the cost. There is no obligation to proceed at consultation.

Which Should You Choose?

If your ED has a vascular component — and most cases do — both treatments work by addressing blood flow at a tissue level. Shockwave alone suits patients who prefer a no-injection approach and can commit to multiple sessions. The Priapus shot suits men who want a single comprehensive regenerative session using their own biology. For the strongest outcomes, the Enhanced P-Shot + Shockwave package combines the mechanisms of both in one appointment for £1,350.

The honest answer always depends on your specific clinical picture. Book a confidential consultation with Dr Abbas to get a frank, evidence-based assessment of which path suits you.

Final Thought

Erectile dysfunction is not a character flaw. It is a clinical condition with real, treatable causes — and in 2025, men have better options than ever before. The conversation no longer has to end at a pill that works for a few hours and leaves the underlying problem completely untouched.

The P-shot and shockwave therapy both represent a genuine shift in how medicine approaches male sexual health. They work with your body rather than against it. They address physiology rather than masking symptoms. And for the right patient, they deliver results that last — not four to six hours, but twelve months or more.

The key word, of course, is “right patient.” That is not a disclaimer designed to soften expectations. It is simply the honest reality of regenerative medicine. Dr Abbas says it plainly at every consultation: if the P shot treatment not the correct option for your situation, he will tell you so. No pressure, no hard sell.
