CockTox at Vesper MedSpa on Broadway St typically lasts about three to four months. Most men start noticing changes within 7 to 10 days, the full effect settles in around the two-week mark, and the clinic recommends maintenance sessions to keep results going. Everyone responds a little differently, so think of those numbers as a realistic range rather than a promise.
If you are weighing CockTox in Chicago, the question of how long it lasts usually comes right after "does it work?" and right before "how do I fit this into my life?" This guide walks through the whole timeline, from the first 48 hours to the point where it is time to rebook, so you can plan with clear expectations.
CockTox is the popular nickname for penile botulinum toxin injections. At Vesper, the treatment is listed as P-Tox, and the clinic names Botox as the product used. The clinic describes P-Tox as a wellness treatment that relaxes erectile tissue to support blood flow. Vesper offers it for men concerned about erection quality, including some men who do not qualify for oral ED medications.
It is worth knowing where the science stands. Botulinum toxin is approved for a list of cosmetic and medical uses, and penile injection is not on that list, which makes it an off-label use (MedlinePlus). Researchers have studied intracavernosal botulinum toxin, particularly for men who did not respond well to standard ED medication, and a 2026 umbrella review is now grading how strong that evidence really is. In plain terms, the treatment is promising, still being studied, and best approached with realistic goals.
According to Vesper's P-Tox treatment details, results typically last 3 to 4 months. That range reflects how botulinum toxin behaves anywhere in the body. The toxin quiets nerve signals to the targeted muscle for a period of time, and the body gradually restores those signals. When that happens, the effect fades.
Fading tends to be gradual, not sudden. Most men describe it less like a light switching off and more like a dimmer slowly turning down over a few weeks.
The appointment itself is short. Vesper lists a session time of about 20 to 30 minutes, performed in a private clinical setting. Most men go back to regular activities the same day, which is part of why the treatment appeals to people with full calendars.
The one firm pause is intimacy. Vesper advises waiting 24 to 48 hours before sexual activity. Mild tenderness or a small bruise at the injection points can happen, and those reactions usually settle on their own. If anything feels more intense than mild soreness, call the clinic rather than waiting it out.
Here is the general rhythm, based on the clinic's published timeline:
Two weeks matters for planning. If you are booking around a trip, a milestone, or an anniversary, schedule at least two weeks ahead so you are not judging results too early.
Once the effect has settled, months two and three are usually the steady stretch. This is when you can best judge whether the treatment is meeting your goals and whether a follow-up makes sense.
Toward the end of month three and into month four, gradual fading is common. Some men notice it a bit earlier, others a bit later. Keeping a few simple notes on when you first noticed changes and when they started to soften can make your next consultation far more productive.
Two men can receive the same treatment and describe different experiences. A few factors help explain why:
Because results last a few months, CockTox works best when you treat it as a routine rather than a one-off. That idea lands differently depending on how you live.
If your weeks run on back-to-back meetings in the Loop or River North, the easiest approach is to book your next visit before you leave the current one. A target around the three-month mark gives you a buffer before fading becomes noticeable. Vesper is open until 7 PM most weekdays, so an after-work appointment on Broadway St is realistic even on a heavy day.
Some clients care less about squeezing in a visit and more about the whole experience feeling effortless. Vesper notes an exclusive concierge service, and asking about it at your consultation is a smart way to keep maintenance private and low-effort. Lining up visits with other treatments you already get can also cut down on extra trips.
You do not have to commit to a year of appointments upfront. Many men do one round, live with the results through the full three to four months, and then decide. That is a reasonable way to find out what the treatment actually does for you.
Some issues are worth raising during your consultation:
None of this is meant to scare you off. It simply means CockTox works best as part of a full picture of your health, not a stand-alone fix.
CockTox may be a fit if you are an adult man who wants extra support for erection quality, understands that the effect is temporary, and is comfortable with a treatment whose evidence is still developing. It may not be the right first step if you have not yet had a medical evaluation for new ED symptoms, if you are hoping for permanent change, or if your main goal is a larger size.
A private consultation at Vesper is where those details get sorted out, including your health history, your goals, and whether a related option like Scrotox is relevant to what you are hoping to change.
Usually not. Most men notice a gradual softening of the effect toward the end of the three to four month window rather than an abrupt drop. Tracking when you first noticed changes helps you time your next visit.
Retreatment timing is a clinical decision, and spacing matters with any botulinum toxin product. If you feel results are fading early, talk with your Vesper provider instead of rushing to rebook. They can review your response and recommend appropriate timing.
No. CockTox, listed as P-Tox at Vesper, targets the penis and is offered for erection quality and blood flow concerns. Scrotox treats the scrotum and is aimed at a smoother appearance, comfort in tight clothing, and temperature regulation. Some men do both, but they solve different problems.
Only if you want to keep the effect. Botulinum toxin is temporary by nature, so stopping simply means the effect fades as it normally would. Many men see it as an ongoing wellness routine, and others use it for a set period and then reassess.
Yes. Vesper is located at 3916 N. Broadway St in Northalsted, an easy trip from Lakeview, Andersonville, and Lincoln Park, with weekday hours running into the early evening. Appointments take place in a private clinical setting, and you can ask about concierge options when you book.
The best CockTox experience is the one you have planned for. Expect first changes in about a week, full results around two weeks, and a three to four month run before it is time to decide on maintenance. Add realistic goals and an honest health conversation, and you will know exactly what you are signing up for.
