If you’ve ever Googled “do penile injections increase size,” you’re not alone. More men than ever are exploring aesthetic and sexual wellness treatments.
Concerns about penis size are common and often motivate men to seek information about penile injections and other enhancement options.
You may have heard claims about enhancement, girth, and the “real way to increase your size,” and want clarity.
You want facts and to know what works, what’s hype, and whether stepping into a clinic like InjectCo is worth your time. Let’s break down what penile injections really do and whether they live up to the promise.
Before anything, let’s clear this up: Penile injections are a broad term. There are several distinct approaches available, each designed to address a different goal in men’s sexual wellness and performance.
These are considered medical procedures and fall under the broader category of penile enhancement procedures. Here’s what we offer at InjectCo:
Penile enhancement procedures can also include options like autologous fat injection and surgical treatment, but InjectCo focuses on minimally invasive medical procedures.
Based on these options, it’s easy to understand that not all penile injections are meant to increase size. Some are performance-oriented, others cosmetic.
If you’re unsure which treatment fits your goals, schedule a discreet consultation with our licensed provider. It is important to consult a qualified healthcare professional before choosing any penile enhancement procedure.
Now that you understand the different types of penile injections, the next step is knowing how they actually work inside your body. Each method targets a unique aspect of sexual health (whether it’s blood flow, volume, or performance) to deliver visible and functional results.
Each kind works in its own way:
The science may differ from one treatment to another, but the goal remains the same: achieving real, noticeable results.
So now let’s get down to the question we get asked about the most during consultations: do penile injections actually increase size, or do they simply enhance how your body performs and appears?
To answer this, it helps to separate perception from measurable change. While many men notice improvements in fullness or firmness, true anatomical growth depends on the treatment type and how your body responds.
Improvements in penile appearance and sexual performance are often reported, but true enhancement results depend on individual male anatomy and overall men’s health.
Psychological factors, such as small penis syndrome and penile dysmorphophobic disorder, can also shape patient expectations and satisfaction with sexual function. Here’s what the science and our clinical experience actually show:
Most non-surgical injections, like the P-Shot (a PRP or platelet-rich plasma injection for the penis), don’t make the penis or the erect penis much longer.
Numerous credible sources assert that the P-Shot “lacks scientific evidence” for size enhancement.
PRP may help with circulation or erectile function, but it doesn’t always work as promised to make things longer. A review of PRP for erectile dysfunction indicated that while there are encouraging functional outcomes, alterations in penile size remain unsubstantiated.
The hard truth is that injections alone won’t guarantee a measurable increase in penis length. Penis enlargement surgery is one way to make your penis longer permanently, but it has more risks than other ways to do it without surgery.
Penile girth enhancement is the primary goal of these procedures for male patients, aiming to increase penile girth through minimally invasive techniques.
Studies evaluating the efficacy and safety of injectable fillers, such as hyaluronic acid injections, have shown that men can achieve measurable increases in penile circumference or diameter.
However, these studies also note the potential for skin irregularities, such as bumps or uneven texture, and other serious complications, especially if non-medical substances are used.
For example, one systematic review reported that HA injections significantly enhanced girth, and patient satisfaction also improved. In one series, flaccid girth increased by about 2.5 cm (range 1.5 – 4 cm) and the effect lasted roughly 9-24 months.
Injectable fillers like hyaluronic acid are often compared to injected fat as alternative methods for penile girth enhancement.
While injected fat involves transferring fat from other body areas, it may result in uneven distribution, resorption, or irregular shapes, whereas injectable fillers generally offer more predictable results but still carry risks of skin irregularities and other complications.
That said, the gain in girth comes from added volume under the skin (the filler material), not from natural tissue growth. Maintenance and realistic expectations remain critical: this is thicker girth, not longer length, and not necessarily permanent.
So the truth is this: penile injections can modestly improve girth but don’t permanently increase length.
Filler-based enhancement results for girth typically last 12–24 months, depending on the product and your body’s metabolism. PRP enhancement results vary more in longevity.
While some men see improvement in function or firmness, consistent evidence of size change or long-term data is limited.
Most procedures offer minimal downtime, allowing patients to return to normal activities quickly. So if you want to maintain your appearance, plan on touch-up or maintenance sessions.
Not every man is an ideal candidate for penile injections, which are procedures within the field of sexual medicine and may be considered for men experiencing sexual dysfunction. That’s exactly why an expert consultation with a healthcare professional matters. These treatments work best for those who understand what they can and can’t achieve.
You’re a good candidate if:
You’re not an ideal candidate if you expect major, permanent length gain, have active infections, bleeding disorders, or take medications that increase injection risks.
Every treatment begins with a thorough medical assessment by a healthcare professional to ensure your plan is safe, customized, and aligned with your goals.
Once you’ve decided to move forward, knowing what the treatment experience looks like can help ease any hesitation. Most patients are surprised by how quick and comfortable the process actually is.
Here’s what will happen from beginning to end, so you can go in with confidence and knowledge.
Schedule a confidential consultation to see what outcome you can expect.
Penile injections are minimally invasive, provide visible girth results, and offer functional benefits without the high risks of surgery.
Penile augmentation and penile enhancement procedures include a range of options, from injections to surgery, allowing men to choose the approach that best fits their goals and comfort level.
On the other hand, surgical procedures may offer greater gains but come with higher complication rates and a longer downtime.
Your other options include the use of certain devices and traction therapy that can support small improvements but require consistent use. Shockwave therapy is another non-invasive option that can treat erectile dysfunction and improve penile tissue health.
Lastly, oral medications help with erectile function, not size. This is mostly why many men choose InjectCo’s medically guided approach for confidence-boosting results without the risks of invasive surgery.
Transparency is key when it comes to penile injections. Patients deserve to understand not just the price, but the value behind each option.
InjectCo’s PRP (P-Shot) treatment starts at $1,700. This fee covers consultation, preparation, and injection performed by a licensed provider.
For girth enhancement, pricing depends on the type and quantity of filler used. PRP injections start at $799 but offer better structure, smoother results, and longer-lasting effects, often requiring fewer touch-ups over time.
Some patients choose to combine PRP with filler for enhanced aesthetic and functional results. Combination sessions naturally increase the overall cost, but they also provide a more comprehensive approach to both appearance and performance.
After a consultation, each patient receives a personalized quote detailing the full breakdown of treatment and follow-up recommendations.
Because filler gradually metabolizes, maintenance every 12 to 24 months is recommended to preserve results. During these visits, InjectCo’s licensed injectors assess outcomes, adjust treatment plans, and ensure continued safety and satisfaction.
When you ask if penile injections increase size, the truthful answer is that they can improve girth but not permanently increase length. The results depend on your goals, anatomy, and the expertise of your provider.
InjectCo offers honest, medically backed solutions that help patients look and feel their best. Penile injections may be the safest and most effective way for men who want to increase their girth and performance to get a bigger penis.

Q: Do penile injections make you bigger for good?
A: No. The results of girth last for about 12 to 24 months. There is no consistent data to support PRP’s effects on length.
Q: How long do fillers for the penis last?
A: Most hyaluronic acid fillers last between one and two years, but this depends on the type of filler and how fast your body breaks it down.
Q: Is the P-Shot worth it for performance and problems with getting an erection?
A: There is evidence that PRP may help with erectile function, but it has not been shown to permanently increase size.
Q: Do penile injections hurt?
A: You might feel some pain, but numbing makes it less so. InjectCo gives you local anaesthesia to make sure you’re comfortable.
Q: How long does it take to recover after treatment?
