P-Thick™
Natural girth enhancement
using your own biology
A non-surgical penile girth enhancement treatment using DermaPRP — a thermally processed form of your own platelet-rich plasma engineered to behave like a soft tissue filler, without synthetic materials.
P-Thick sits between two categories: it delivers immediate results like a filler, but uses entirely autologous material like a regenerative treatment. Understanding that distinction — including its limitations — is essential before choosing this option.
Overview
What is P-Thick (DermaPRP)?
P-Thick uses a specialized form of PRP known as DermaPRP — processed to behave more like a soft tissue filler than a standard PRP injection. Through a controlled heating and cooling method, the plasma proteins are denatured and thickened into a gel-like consistency that can provide immediate volumizing effect when injected under the skin of the penis.
The result is a material that shares properties with both regenerative PRP and volume-based fillers — but is made entirely from your own blood, carrying no risk of allergic reaction and introducing no synthetic substances.
It is important to understand that the thermal processing which gives P-Thick its filler-like consistency also reduces its regenerative biological activity compared to standard PRP. P-Thick is best understood as a natural filler — not a regenerative treatment.
Standard PRP is liquid in consistency and works primarily through biological signaling — growth factors stimulate tissue repair, blood vessel formation, and cellular regeneration over weeks to months.
DermaPRP is thermally modified into a gel-like consistency. This makes it suitable for immediate volumizing, but the heating process reduces the concentration of active growth factors — meaning less regenerative benefit.
Think of the difference this way: standard PRP heals and improves tissue. DermaPRP fills and adds volume — using autologous material.
Procedure
How P-Thick is prepared and administered
The procedure involves four distinct steps, from blood draw to injection. The entire process is performed in-office in a single session.
Blood collection and PRP isolation
A blood sample is drawn and spun in a centrifuge to concentrate the platelets and growth factors into platelet-rich plasma — the same starting point as any PRP procedure.
Thermal processing — the “hot and cold” method
The PRP is exposed to controlled heating and cooling cycles. This process denatures and thickens the plasma proteins, transforming the liquid PRP into a gel-like, filler-consistency substance.
This step is what gives P-Thick its immediate volumizing effect — and is also what reduces its regenerative biological activity compared to unprocessed PRP.
Blending with unprocessed PRP
The thermally processed gel is combined with a portion of unprocessed PRP. This blend helps preserve some biological activity in the final injectable product while maintaining the filler-like consistency.
Injection and shaping
The DermaPRP material is injected beneath the skin of the penis in a controlled pattern designed to create even, natural-looking girth enhancement. Provider technique and experience significantly influence distribution and final result.
Because results are not reversible, even placement and proper technique are critical. Discuss your provider’s specific experience with DermaPRP before proceeding.
Honest assessment
Advantages and limitations
P-Thick has a genuinely distinctive profile — but understanding both sides is essential for making an informed decision.
Critical consideration
Reversibility — the most important difference to understand
The reversibility question is the single most important factor distinguishing P-Thick from synthetic HA fillers. Every patient should understand this clearly before choosing either option.
Not reversible once injected
The thermally processed PRP material cannot be dissolved. If results are uneven, asymmetrical, or not as expected, correction options are extremely limited.
The material must naturally reabsorb over time — typically 9–12 months. During that period, adjustments cannot be made the way they can with HA fillers.
This makes provider skill, technique, and experience especially critical. It also means patients must have realistic, well-discussed expectations before treatment.
Reversible with hyaluronidase
Hyaluronic acid fillers can be dissolved using an enzyme called hyaluronidase. This allows providers to correct overcorrection, asymmetry, or patient dissatisfaction relatively quickly.
This reversibility is a significant safety advantage of HA fillers over DermaPRP — particularly for first-time patients who are uncertain about their expected outcome.
HA fillers are synthetic, carry a small allergy risk, and do not have the autologous advantage of P-Thick — but the ability to reverse them provides an important safety net.
How it compares
P-Thick vs. alternatives
| Feature | P-Thick (DermaPRP) | Standard PRP (P-Shot) | HA Fillers |
|---|---|---|---|
| Material | Your own PRP (processed) | Your own PRP (unprocessed) | Synthetic hyaluronic acid |
| Consistency | Gel-like (filler) | Liquid | Gel |
| Results onset | Immediate | Gradual (weeks–months) | Immediate |
| Primary goal | Girth enhancement | Function & regeneration | Girth enhancement |
| Reversible | No | No (reabsorbs naturally) | Yes — hyaluronidase |
| Longevity | ~9–12 months | Variable | 12–24 months |
| Regenerative effect | Limited (thermal processing reduces activity) | Higher | None |
| Allergy risk | None (autologous) | None (autologous) | Small risk |
Is it right for you?
Who is a good candidate for P-Thick
Want immediate girth enhancement — not gradual results over months
Prefer a natural, autologous alternative to synthetic HA fillers
Are not primarily seeking length improvement (P-Thick addresses girth only)
Understand and accept that results are temporary and require maintenance
Have had a thorough consultation and understand the irreversibility of the material
Want to combine girth enhancement with P-Long for both dimensions (P-Max)
Common questions
Frequently asked questions
How is P-Thick different from a P-Shot?
The P-Shot uses standard liquid PRP for regenerative purposes — improving erectile function, sensitivity, and tissue health over time. P-Thick uses thermally processed PRP (DermaPRP) to create immediate volume and girth. They use the same starting material but are processed differently and achieve fundamentally different outcomes.
Why can’t P-Thick be reversed?
HA fillers can be dissolved because hyaluronidase — an enzyme — specifically breaks down hyaluronic acid. There is no equivalent enzyme that dissolves thermally processed plasma proteins. The DermaPRP material must naturally reabsorb through the body’s normal processes over approximately 9–12 months. This is why provider technique and pre-treatment consultation are especially important.
How much girth increase can I expect?
Results depend on the volume of material used, injection technique, and individual tissue response. Discuss specific expectations directly with your provider before treatment — they can give you a realistic assessment based on your anatomy and their clinical experience with the procedure.
Is P-Thick the same as P-Max?
No. P-Thick is the girth enhancement component. P-Max is a combination protocol developed by Prestige Medical Group that integrates P-Long (for length) with P-Thick (for girth) into a single comprehensive program. If you want both length and girth improvement, P-Max may be worth discussing with your provider.
What is the downtime after P-Thick?
Most men return to normal daily activities the same day. Some temporary swelling, mild bruising, or irregularities in distribution are possible during the initial healing period. Sexual activity is typically restricted for a short period after treatment — your provider will give specific guidance.
Can P-Thick be combined with shockwave therapy or TRT?
Yes. P-Thick is commonly combined with shockwave therapy to support vascular health alongside girth enhancement, and with hormonal optimization (TRT) as part of a broader sexual health plan. Combination approaches are best planned with a provider who can assess your full health picture.
