Upsize is a medical practice revolutionizing men’s wellness through safe, non-surgical penile enhancement.
About us
Upsize LLC is a pioneering medical practice at the forefront of men’s health, specializing in non-surgical penis enlargement. Founded in 2023 by Dr. Joel Pash and Dr. Jack Friedlander, the company has quickly grown from its California roots to a team of 20 physician afilliates as of April 2025. Headquartered in Roseville, CA, Upsize delivers a safe, minimally invasive solution for men seeking penile enhancement.
The UpsizeTM Procedure uses a proprietary dermal filler technique that increases penile girth by approximately 1–1.5 inches per session (results lasting around two years). Unlike surgical alternatives, this in-office procedure avoids general anesthesia and lengthy recovery, making it a trusted choice for over 1,200 clients to date. Upsize is uniquely positioned in the rapidly expanding men’s health and wellness market, offering a credible medical service in a space that has historically lacked safe options.

From Friendship to Innovation
The two doctors were introduced by Dr. Friedlander’s brother – a longtime friend of Dr. Pash – and they quickly realized they shared a common goal: to develop a safe, effective method for male enhancement that would give men more confidence without the perils of surgery. In 2023, they teamed up to launch Upsize LLC, blending Dr. Pash’s expertise in injectables with Dr. Friedlander’s surgical insight to create a new kind of men’s health clinic.
This vision has guided Upsize from day one. What started as an idea between two friends (and now business partners) has rapidly grown into a multi-city practice setting a new standard in male enhancement.

Upsize’s core offering is a groundbreaking non-surgical enlargement procedure refined over the course of 1,000+ treatments. The technique centers on a proprietary hyaluronic acid dermal filler formula and injection method that the co-founders created and perfected through extensive experience. Over time, they have innovated a special micro-cannula injection approach, virtually eliminating the issue of filler migration (a common complication in other filler techniques) and ensuring smooth, uniform results. The procedure is performed under local anesthetic and typically takes under an hour, with minimal downtime – patients often return to normal activities the same day.
Why choose Us
The filler adds substantial girth instantly – most patients see around a 1-inch or more increase in circumference before leaving the clinic. In some cases, a modest length increase is also noted. Results are long-lasting (up to ~2 years) yet adjustable with touch-up treatments over time.
Upsize’s unique technique ensures even distribution of the filler for a natural appearance without lumps. This approach, exclusive to Upsize, prevents filler migration and other issues that have plagued earlier enlargement methods. The result is a smooth enhancement that feels and looks natural.
The procedure uses FDA-approved dermal fillers off label, that have been widely used in cosmetic medicine for decades, ensuring a strong safety record. Because there’s no surgery, patients avoid the significant risks associated with implants or ligament-cutting operations (such as infections, scarring, or loss of function). Upsize’s doctors are all specially trained in this technique, and the practice reports extremely high satisfaction rates and no serious complications to date.
Unlike surgical approaches, the Upsize procedure requires no general anesthesia or sedation – only a local numbing. Patients typically resume normal daily activities immediately or within hours of treatment, a major convenience factor.
Upsize’s unique story and breakthrough procedure have garnered significant media attention, reflecting a broader public interest in male enhancement trends. The practice and its founders have been featured in numerous media outlets and interviews, helping to demystify the topic of penis enlargement and highlight Upsize’s safe approach:
Upsize was profiled in an in-depth article on the rise of men seeking non-surgical enhancements (sfstandard.com). The piece noted that in just two years, Dr. Pash alone had performed around 600 enlargement procedures in the Bay Area, and it described Upsize as a “nationwide penile enlargement” provider headquartered in Sacramento. The article highlighted how patients opt for Upsize’s injections to achieve noticeable size increases (about 1 to 1.5 inches in girth) without surgery, and it positioned the company at the cutting edge of a new biohacking-driven trend in Silicon Valley. (See: “Junk science: Why Bay Area men are using Botox to enlarge their penises,” SF Standard.)
Dr. Pash has been a guest on over 15 podcasts and YouTube interview shows, where he shares medical insights and addresses common questions about the procedure. For example, he appeared on the Finding Genius Podcast to do a deep dive into the science and outcomes of penile filler treatments. He has also been interviewed on shows like “The Joel Evan Podcast”, “The Optimal Life” and “The Victory Men’s Health Show“, discussing the Upsize procedure and debunking myths around male enhancement. These media appearances have helped educate the public and normalize the conversation around men’s sexual health.
In addition to the above, Upsize has been featured in lifestyle and health publications and various online health blogs and even on unconventional platforms (the co-founders did an interview on the irRational Moms podcast, showcasing the widespread curiosity about their work). The practice’s rapid rise has also drawn interest from industry observers, noting Upsize as a promising startup in the sexual wellness space. Public curiosity remains high, as evidenced by thousands of views on YouTube interviews and a steady influx of inquiries from potential patients every week.
