The P-Shot is an experimental PRP injection, not an FDA-approved ED cure. Here is what the trials actually show, what the guidelines say, and what should come first.
That does not mean it can never help anyone. It means the honest claim is “unproven,” and before an experimental injection, the more important step is finding out why you have ED in the first place, because it is often an early warning of a treatable heart or hormone problem. We offer the P-Shot at Solcara, and we will tell you the truth about it.
- The P-Shot is a PRP injection into the penis, marketed for erectile dysfunction, Peyronie's disease, and sexual enhancement. It is not FDA-approved for any of these uses.[1][2]
- The evidence is mixed and comes from small, short trials. The most rigorous US placebo-controlled trial (61 men) found PRP no better than a saline injection at 6 months.[3]
- An earlier placebo-controlled trial (60 men) was positive, with more men reaching a meaningful improvement on PRP than placebo, but it followed men for only 6 months.[5]
- The AUA (2018) calls PRP for ED experimental and says it should not be offered outside an IRB-approved research protocol; the SMSNA (2021) agrees it should be reserved for clinical trials, not routine practice.[1][2]
- Penile PRP appears well tolerated in short studies (mild soreness, bruising), but long-term safety is not established.[4]
- ED is frequently an early sign of cardiovascular disease or low testosterone, so a proper workup and proven treatments usually come first.[1]
What the P-Shot actually is
The P-Shot, sometimes called the Priapus Shot, takes platelet-rich plasma concentrated from a sample of your own blood and injects it into the penis, marketed to improve erections, treat curvature from Peyronie's disease, and enhance sensation. Using your own platelets sounds elegant and low-risk, and the short-term safety record is reasonable. The mechanism is plausible, which is exactly why the marketing is persuasive. Plausible is not the same as proven, and this is where the evidence gets uncomfortable for the industry.
Start with the regulatory status, because a sales page will blur it. No PRP product is FDA-approved or FDA-cleared to treat erectile dysfunction, Peyronie's disease, or for sexual enhancement. The only FDA clearances for PRP preparation systems cover the device that separates the plasma, for handling in the operating room, not any treatment claim.[1] So any clinic describing the P-Shot as an “FDA-approved procedure” is misstating the facts. The honest framing is that this is an off-label, experimental use of PRP.
Hear from Ashley
A short introduction from Ashley Harwyn, PA-C on what the P-Shot is, who asks about it, and how we approach it honestly in Mount Pleasant and Charleston.
What the evidence on PRP for erectile dysfunction really shows
Here is the part most pages leave out, and it is the section worth reading twice. There are two good placebo-controlled trials of PRP for ED, and they disagree with each other, which by itself tells you the treatment is not settled science.
The most rigorous and most recent is a US trial of 61 men with mild to moderate ED, randomized to PRP or a sham injection. At 6 months, erectile-function scores improved in both groups by a nearly identical amount, with no statistically significant difference between them, and the authors concluded that PRP does not appear effective for ED, at least on its own.[3] In plain terms, the men who got a placebo injection did just as well as the men who got PRP.
The earlier trial, of 60 men, was more encouraging: more men in the PRP group reached a meaningful improvement in erectile function than in the placebo group at 6 months.[5] It is a real result and worth knowing. It is also a single small study with only 6 months of follow-up, and it used a low threshold for what counted as improvement. When you put the two trials side by side, the honest summary is that the benefit is uncertain, the durability is unknown, and the best-designed trial was negative. Anyone promising you reliable results is going well past the data.
That penile PRP is generally well tolerated in short trials (mild soreness or bruising), and that one 60-man trial found more men reaching a meaningful improvement with PRP than placebo at 6 months.
That the P-Shot reliably treats ED. The most rigorous US placebo-controlled trial found it no better than a saline injection, no PRP product is FDA-approved for ED, and the AUA and SMSNA both call it experimental.
The P-Shot compared with proven ED treatments
With the evidence laid out, the P-Shot lines up against the established options on what matters most: whether it is proven, whether it is FDA-approved, and what role it realistically plays. The table below compares them honestly.
| Option | Evidence and approval | Honest role |
|---|---|---|
| P-Shot (PRP injection) | Mixed trials, best one negative; not FDA-approved; AUA and SMSNA call it experimental | Unproven; research-grade, realistic expectations only |
| PDE5 inhibitors (sildenafil, tadalafil) | Strong evidence, FDA-approved, first-line | The proven starting point for most men |
| Injections, vacuum devices, implants | Established, effective options for men who need more | Proven escalation when pills are not enough |
Six things to weigh
Tick the ones that describe you. The more you tick, the more a real workup or a proven treatment should come before any experimental injection.
Two things stand out when you read it honestly. First, the most proven and least expensive options are the FDA-approved ones, not the P-Shot. Second, none of this matters until someone has looked at why you have ED, because that is where a real evaluation starts and where the most important findings often turn up.
What the guidelines say, and treating the real cause
This is the part a clinic selling injections has no incentive to tell you. Both major professional bodies have looked directly at PRP for ED and reached the same conclusion. The American Urological Association states that PRP therapy should be considered experimental and should not be offered to men with ED unless it is given within an IRB-approved research protocol.[1] The Sexual Medicine Society of North America, reviewing PRP, shockwave, and stem-cell therapies together, concluded that these treatments are experimental and should be reserved for clinical trials and not offered in routine clinical practice.[2]
Just as important is what ED often signals. Erectile dysfunction is frequently an early sign of cardiovascular disease, and it is commonly linked to low testosterone, diabetes, medication side effects, and sleep or mental-health issues. A proper evaluation, including the right laboratory work and a review of your hormones, can catch a problem that matters far more than any injection, and often points to a treatment that actually works. Treating the cause beats treating the marketing category.
Considering the P-Shot for ED in Charleston? Erectile dysfunction is often an early sign of a heart or hormone problem, so a real workup comes before any injection. Call 843-981-0870 and we will check the things that matter first, then talk honestly about your options.
How we approach the P-Shot in Mount Pleasant and Charleston
If you are weighing the P-Shot, the smartest first move is not choosing an injection, it is getting an honest evaluation. A good clinic examines you, checks your cardiovascular risk and hormones, offers the proven treatment if one fits, and only then discusses experimental options, with the real evidence on the table.
At Solcara Health, that is the order we work in. We see patients at two locations: the Mount Pleasant office at 496 Bramson Ct, convenient to Old Village, I'On, Park West, and Daniel Island, and The Longevity Club downtown at 163 Rutledge Ave, in the Charleston medical district near MUSC. Ashley Harwyn, PA-C is board certified through the American Academy of Anti-Aging Medicine, and she will tell you plainly where the evidence is thin. If a proven treatment fits, we start there. If you still want the P-Shot with realistic expectations fully explained, we will discuss it honestly as the experimental option it is, not as a guaranteed cure. The women's counterpart, the O-Shot, is explained with the same candor.
