✅ Medically reviewed | Updated July 2026

You have read the reviews, watched a few videos, and now one question keeps circling back: how long does the P Shot actually last? It is the single most googled question about this treatment, yet most clinic websites answer it in a single vague line — “results vary” — and move on. That is not good enough when you are deciding whether to spend over a thousand pounds on a procedure.

This guide breaks down P Shot results duration properly. You will learn what happens week by week, which factors speed up or shorten your results, and the maintenance habits that genuinely make a difference. We also cover real appointment details, pricing, and what happens inside a London clinic room, so you finish this article with answers rather than more questions.

What Is the P-Shot? A Quick Refresher

The P-Shot, also called the Priapus Shot, uses platelet-rich plasma drawn from your own blood. A clinician spins the blood in a centrifuge, separates the platelet-rich layer, and injects it into penile tissue using fine needles.

Doctors do not add synthetic drugs or foreign material at any stage. Your body does the healing; the treatment simply directs it. The growth factors inside PRP stimulate new blood vessels, support nerve repair, and encourage collagen production in the tissue that fills with blood during an erection.

This mechanism explains why the P-Shot appeals to men who cannot tolerate PDE5 inhibitors like Viagra, or who simply prefer a natural, drug-free approach to intimate health.

P Shot Results Duration — What Really Happens

Most competitor articles skip straight from “the injection” to “the results,” ignoring the timeline in between. Here is the realistic breakdown.

Week 1 to 2: The Settling Phase

Your tissue settles during these first two weeks. Some men notice a mild increase in sensitivity almost immediately, though visible changes remain minimal at this stage. Doctors advise abstaining from sexual activity for four to five days so the treated area can recover properly.

Week 4: The First Signs

By week four, many patients report firmer morning erections and improved sensitivity. The angiogenic process — new blood vessel formation — is actively underway beneath the surface. This is often the point where patients start believing the treatment is working.

Weeks 8 to 12: Peak Results

This window typically produces the clearest P shot before and after changes. Erection quality, firmness, and sensitivity improvements become most noticeable here. Men with Peronei’s disease sometimes notice reduced curvature or discomfort during this phase too.

12 Months and Beyond: Sustained Results

On average, results last 12 months or longer, though individual timelines vary based on age, circulation, and lifestyle. Many patients choose an annual maintenance session to keep their results consistent rather than waiting for a noticeable decline.

Factors That Influence How Long P-Shot Results Last

No two men experience identical P Shot results duration, and understanding why helps you set realistic expectations.

Age and Baseline Vascular Health

Younger men with good circulation typically retain results longer than older men with existing vascular conditions such as diabetes or high blood pressure. Age does not disqualify anyone from treatment, but it does shape the timeline.

Lifestyle Habits

Smoking, excessive alcohol consumption, and a sedentary lifestyle restrict blood flow and can shorten how long p shot benefits last. Men who exercise regularly and manage their cardiovascular health tend to hold onto results for longer.

The Underlying Condition Being Treated

Erectile dysfunction linked purely to vascular causes tends to respond more consistently than cases involving significant psychological or hormonal factors. Peyronie’s disease and lichen sclerosus cases follow their own separate timelines, since the treatment targets scar tissue and inflammation rather than blood flow alone.

Practitioner Skill and PRP Processing Quality

This is the factor competitor sites almost never mention. The concentration of platelets in your PRP directly affects how long the growth factors keep working. A dual-spin centrifuge protocol produces a noticeably higher platelet yield than a standard single-spin method, which is one reason injection technique and lab quality matter as much as the treatment itself.

Maintenance Tips to Extend Your P Shot Results

Duration is not fixed. A few practical habits genuinely help you get more mileage from your Priapus shot.

Book an Annual Top-Up Session

Since results average around 12 months, scheduling a follow-up session before symptoms return keeps your progress steady rather than starting from scratch each time.

Protect Your Vascular Health

Reducing alcohol intake, quitting smoking, and staying active all support the blood vessel growth that the treatment relies on. These habits cost nothing and extend results for free.

Consider Combining with Shockwave Therapy

Low-intensity shockwave therapy enhances cellular uptake and supports additional blood vessel formation when paired with PRP in the same appointment. This combination is often recommended where vascular factors play a significant role in erectile dysfunction.

Use a Vacuum Device During Early Healing

Where clinically appropriate, a medical-grade vacuum device supports blood flow to the treated area during the early weeks. This small addition to your aftercare routine can support better long-term outcomes.

P Shot Before and After: What to Realistically Expect

Photos online rarely tell the full story. Genuine p-shot before and after outcomes develop gradually over eight to twelve weeks, not overnight. Reported improvements include firmer erections, increased sensitivity, better morning erections, and — for some patients — reduced Peyronie’s curvature.

Results are not guaranteed and vary between individuals. Any responsible clinic will tell you this honestly rather than promising universal outcomes.

How Much Does the Priapus Shot Cost in London?

Pricing transparency is another area where many competitor pages fall short, often listing costs as “price on consultation” with no real figure. At Dr SNA Clinic, the standard P-Shot starts from £1,250, using a dual-spin PRP protocol. An enhanced package combining the P-Shot with shockwave therapy is priced from £1,350.

Every package includes a consultation, dual-spin PRP processing, topical numbing or a nerve block, injections performed personally by the treating doctor, and both a six-week and twelve-week follow-up. 0% finance is available for patients who prefer to spread the cost.

If male enlargement injections cost in the UK is something you are researching alongside duration, it helps to compare total value — consultation, follow-ups, and aftercare included — rather than the headline price alone.

Your P-Shot Appointment — What to Expect

A full P-Shot appointment takes between 30 and 45 minutes from start to finish. Here is the general flow patients experience:

Preparation (10 minutes): A topical numbing cream takes effect, or a nerve block is offered for patients with a lower pain threshold.
Blood draw (5 minutes): A small, routine blood sample is taken from your arm.
PRP processing (15 minutes): The sample goes into a medical-grade centrifuge using a dual-spin protocol.
Injection (10 minutes): The clinician administers fine-needle injections into precise treatment sites.
Aftercare: Doctors provide guidance on activity, and a vacuum device may be recommended for home use.

Most patients return to normal daily activity, including driving and desk work, the same day. Doctors generally advise avoiding sexual activity for four to five days afterward.

For men researching P shot london options, appointments are available at 48 Wimpole Street, Marylebone, London W1G 8SF, with clinic hours running 10:00 to 18:00 UK time.

Is the P-Shot Right for You?

The treatment suits men experiencing mild to moderate erectile dysfunction, particularly where vascular factors play a role, as well as men managing Peronei’s disease, reduced sensitivity, or premature ejaculation with a physical component.

It is not suitable for patients with active infections, bleeding disorders, uncontrolled anticoagulant use, or those currently undergoing pelvic cancer treatment. A face-to-face consultation remains the only reliable way to confirm suitability, since medical history varies so much between individuals.

Dr SNA Clinic in London conducts every consultation and injection personally, rather than delegating the procedure to junior staff — a detail worth checking wherever you choose to book, since injection precision directly affects your results.

If you would like to see the procedure explained in more depth, the P-Shot treatment and pricing page walks through the full process, and the clinic’s YouTube channel includes patient interviews and a doctor-led explanation of the procedure worth watching before your consultation.

Frequently Asked Questions

Does the P-Shot hurt?

Most patients describe mild pressure rather than pain, thanks to topical numbing cream. A nerve block is available for those with a lower pain threshold.

How soon will I notice results?

Early changes often appear around week four, with the clearest improvements typically emerging between weeks eight and twelve.

Can I combine the P-Shot with other treatments?

Yes. Shockwave therapy is commonly combined with the P-Shot to further support blood vessel formation, particularly where vascular causes are significant.

How often should I repeat the treatment?

Many patients choose an annual maintenance session, though your practitioner will advise based on your six and twelve-week follow-up reviews.

Is one session enough?

A single session helps many patients, but your consultation will determine whether your specific condition benefits from a second treatment or a maintenance protocol.

Final Thoughts

P Shot results duration depends on far more than a single average figure — it depends on your age, vascular health, lifestyle, and the quality of the PRP itself. Understanding this timeline helps you set realistic expectations and get genuine value from the treatment rather than being surprised when results shift over time.
