PhalloFILL® Acid Girth Enhancement

Using the PhalloFILL® protocol, patients have reported increases in penile girth ranging from approximately 1/4 to 1/3 of an inch per session. Over multiple sessions some patients have shared that their overall girth increased by 1 to 1 1/2 inches or more, depending on individual goals and anatomy. after multiple sessions depending on goals. PhalloFILL® does not change penis length. The number of units administered varies based on anatomy and provider discretion.

Key averages to consider:

• The average flaccid penis girth is 3.5–4 inches. Many men wish to reach 5–6 inches flaccid.
• The average erect penis length is 5.5 inches (PhalloFILL® does not change length).
• The average erect penis girth is 5 inches. Many men aim for 6+ inches.

On average, 18–30 units may be administered over 3–6 sessions depending on anatomy and provider discretion.

No. Some before-and-after photos may give the impression of added length, often because the penis appears fuller when flaccid after the procedure.

PhalloFILL® is designed specifically for girth enhancement along the shaft, not lengthening. While filler can be injected into the glans (head), the structured PhalloFILL® protocol focuses on the shaft where the procedure is intended to add girth. Individual experiences and outcomes may vary.

Other methods, such as traction devices or surgeries, are sometimes used by people seeking length changes. Traction devices involve wearing a device over time that applies gentle stretching. Surgical approaches exist, but they are separate from the PhalloFILL® protocol. PhalloFILL® focuses solely on customizable girth enhancement using reversible products, with procedures tailored to each individual’s goals.

After a PhalloFILL® procedure, most people follow the guidance provided by their trained provider to help support the treatment process. Many patients are given a compression wrap or similar support bandage as part of their post-procedure routine.

Providers typically recommend avoiding sexual activity or self-pleasuring for about 7–10 days, though exact instructions can vary depending on the provider, individual prefernces, and patient anatomy. Following your provider’s guidance can help you feel more confident that your procedure is progressing smoothly.

Some people notice minor temporary changes in appearance, particularly when the penis is flaccid. These variations are a normal part of the process, and additional sessions or adjustments may be considered to meet individual aesthetic goals.

The PhalloFILL® protocol involves the careful application of hyaluronic acid filler along the shaft of the penis. The placement is designed to be symmetrical and can be adjusted based on individual preferences and goals.

After the procedure, the penis is fitted with post-care bandaging to help support the area and guide the settling of the filler. Treatments are customizable, and additional sessions can be scheduled if desired.

Because PhalloFILL® uses hyaluronic acid based filler, it offers flexibility in adjusting or modifying the appearance over time. Patients may choose to maintain, refresh, or adjust their results through future sessions as part of a fully customizable approach.

Patients who have undergone the PhalloFILL® procedure report varying levels of filler retention over time, with many noting noticeable results for 3–4 years or longer. Routine maintenance sessions, typically involving 2–6 units every 12–18 months, may be scheduled for those who wish to refresh or adjust their appearance.

The PhalloFILL® protocol is highly customizable, allowing providers to tailor treatment plans to each patient’s individual goals. Sessions involve multiple injections, with the option to adjust or remove filler if desired.

Because each patient’s anatomy and preferences are unique, experiences with filler retention and results may vary. Some patients choose follow-up sessions as part of their ongoing enhancement plan, while others may be satisfied with their initial treatments for longer.

PhalloFILL® providers work closely with patients to ensure that each session aligns with their personal goals, offering flexibility and control over the overall enhancement experience.

Filler longevity can be influenced by many factors, including how the body processes it over time. Areas with greater blood flow or lymphatic activity often show different patterns of metabolization than areas with less activity. The PhalloFILL® protocol was developed with this in mind, placing filler between two layers of natural connective tissue (fascia) along the shaft. Patients have reported that this location appears to provide results that feel more durable for them compared to filler placed in other regions of the body.

The PhalloFILL® protocol is offered in units of filler, with package options designed to suit different preferences:

• Single session (4–6 units): $2,800–$4,350
• 10-unit package: $5,500–$6,250 (typically completed over 2 sessions)
• 20-unit package: $9,900–$10,900 (typically completed over 3–4 sessions)

Pricing is determined by provider location. Financing options may be available.
