About the Procedure

What Is Upsize™?

Upsize™ is a physician-performed penis enlargement procedure using hyaluronic acid dermal filler. The in-office treatment takes under an hour, requires no surgery or implants, and involves minimal downtime. Individual results vary.

Unlike pills, pumps, or surgical penis enlargement with weeks of recovery, the Upsize™ penis filler procedure delivers immediate, visible results you can see before leaving the office.

Plus Firm-X™ — Penile Neuromodulator

Firm-X™ is Upsize™'s penile neuromodulator procedure — a single in-office injection that improves erectile firmness and increases flaccid hang for about 6 months per treatment. Takes about 20 minutes, no downtime, often performed in the same visit as the Upsize™ filler procedure.

Fat Transfer vs. HA Fillers for Penis Enhancement: Complete Comparison

A detailed comparison of fat transfer versus hyaluronic acid fillers for penile girth enhancement—examining results, longevity, complications, and which approach produces better outcomes. Fat transfer (also called lipofilling or fat grafting) and hyaluronic acid fillers represent two fundamentally different approaches to penis girth enhancement. Both add volume beneath the penile skin, but they use different materials and produce different results.

Firm-X: How Penile Botox Improves Size, Firmness & Performance

Every man has experienced it: the penis that shrinks dramatically in response to cold water, stress, anxiety, or simply without apparent reason. This retraction is controlled by the dartos muscle—smooth muscle tissue in the penile shaft and scrotum that contracts involuntarily.

Combining Firm-X with the Upsize Procedure: Why Patients Do Both

Understanding why many patients achieve optimal results by combining girth enhancement with neuromodulator treatment—and how these procedures complement each other. The Upsize Procedure and Firm-X treatment address different aspects of penile enhancement. Upsize adds actual girth through hyaluronic acid filler.
