As men, we feel the need to take care of business, including what goes on in the bedroom. We will do what’s needed to get an edge on optimizing sexual performance. That edge is BOCOX ™ at Activation Clinic in Honolulu.

BOCOX ™is a fast, simple, non-surgical procedure that maximizes blood flow to the shaft of the penis, whether it is erect or at rest. In other words, if you’re a “GROW-er,” it will help make you a “SHOW-er.”  Many BOCOX ™ patients have impressive results with regard to aesthetics, as well as to erectile function, including a longer, wider flaccid (at rest) penis and firmer, stronger, longer erections.  All of the BOCOX ™ benefits make a powerful difference in your performance and confidence in the locker room and especially in the bedroom.

What is BOCOX™?


BOCOX™ is a no downtime, non-surgical, male enhancement procedure that could increase the length and girth of the flaccid penis. BOCOX™ treatment takes less than 30 minutes and is virtually painless.

BOCOX™ helps the penis remain at full length and reduces size loss due to shrinkage (Hyperactive Penile Retraction Reflex). BOCOX™ has also been shown to improve erectile quality, decrease premature ejaculation, and boost confidence!

The BOCOX™ Procedure


The BOCOX™ procedure is based entirely on sound medical principles. BOCOX™ utilizes the well-known and researched neuromodulator Botox®.

Botox® has been used for decades successfully to smooth wrinkles and fine lines and has a very high safety profile. The BOCOX™ procedure simply harnesses the same technology successfully used for cosmetic procedures, to increase blood flow to the penis. Botox® enhances male sexual function by relaxing the smooth muscles that control blood flow through the blood vessels of the penis.  When the smooth muscle relaxes, the blood vessels increase in diameter, and more blood flows into the penis—causing improved erection as well as increased length and/or girth at rest.

After receiving BOCOX™ at Activation Clinic in Honolulu, patients have reported reliable improvement in blood flow to the penis, resulting in harder, longer-lasting erections, as well as a longer and/or wider flaccid (at rest) penis.



Dr. Cho at Activation Clinic is the only doctor in Hawaii who is trained and certified to administer BOCOX™ treatments. The procedure is in-office and takes approximately 30 minutes.

Topical anesthesia (numbing cream) will be used to numb the penile tissue. Dr. Cho will then inject Botox® into the corpus cavernosum, the spongy erectile tissue of the penis.  With topical anesthesia, patients usually experience minimal discomfort during the injections.

For many patients, results consistently improve with continued treatment and can be optimized with other treatments and therapies such as the GAINSWave® or the P-shot™.

The Benefits of BOCOX™

BOCOX™ boasts a range of benefits in penile health, function, and appearance with minimal procedural discomfort, minimal side effects, and virtually no post-treatment downtime. BOCOX™ is safe and effective as an alternative or complement to GAINSWave® or the P-shot™, with a majority of patients experiencing:

  • Increased blood flow
  • Increased penile length and girth in flaccid state (at rest)
  • Reduced occurrence of premature ejaculation
  • Healthier penile tissue
  • Firmer erections
  • Improved self-esteem and confidence


Will BOCOX™ make my penis bigger?

Studies have shown that BOCOX™ can improve the length and girth of your penis. However, this result is not the primary function of the treatment and does not happen for everyone.

With that being said, many men see an increase in the size of their flaccid penis after a BOCOX™ treatment, as well as an overall reduction of a typical penis retraction associated with ‘shrinkage’.

Penises tend to look smaller when flaccid because the internal tissues of the penis retract back into the pelvic cavity. But this is even more noticeable for men with “hyperactive retraction reflex.” Men suffering from this experience excessive shrinkage of their penis and sometimes even complete retraction.

Although BOCOX™ is not targeted primarily at those wanting to increase the length and girth of their penis, many men have opted for this revolutionary treatment to increase their penis size.
