How to read these numbers

Each figure uses one selected change per account and dimension. The archive contains gains/success posts; it cannot estimate typical buyer outcomes or success rates. Reports cover the device family, not a verified effect of a particular model. Length and girth may come from different accounts and periods.

Every usable sample is shown. One account is an individual change; two to four is a small sample. Five does not establish reliability. Missing measurements are not zero gain. Method and device groups overlap.

Length range: 0.00 in to 1.30 in.Girth range: 0.25 in to 0.30 in.Full methodology

Filter by recorded routine

Routine labels describe what the author recorded. Sole-use reports are still self-reports and do not establish causation. Missing routine details remain unknown.

How long did these accounts report?

1.5 months median elapsed period · timing available for 2 of 7 accounts.

Reported periods: 1.0–2.0 months.

The timing subset may differ from the full gain sample. These are reported periods, not a timetable for your results.

Calendar rates and calculation detail

Median individual rate: 0.37 in/month across 2 timed accounts. Each change is divided by its own elapsed period. Breaks, temporary changes and consistency are not controlled. Do not extrapolate this into future gains.

PeniMaster at a glance

  • Rod and belt options
  • Weight configuration
  • Different attachments

Keep in mind: PRO Basic is an attachment, not a complete traction setup. Confirm whether your package includes the rod or belt system you intend to use.

Compare the models
Know what you’re buying

Choose the configuration, not just “PRO”.

PRO Basic is the attachment system. Rod and belt packages pair it with different traction components. Classic is separately named, and the weight expander belongs to hanging.

Rod configuration

PeniMaster PRO rod system

The PRO attachment paired with the rod expander. The official shop identifies the complete system as item PMP-002.

Before buyingCheck the complete system, not replacement rods.

I waited until they healed and resumed training. Then 2 weeks later I had another blister and had to stop again. I believe it happened around 5 times and still I gained 2 cm. Maybe those stops for blister recovery worked as decons. Extender is similar to Apex but generic from China. They name it Size Master. But Apex is safer.

Well, really, the first half-inch was accomplished just by learning how to do a bone-pressed measurement. But the rest was genuine gains, and my wife complimented me several times!
Recorded report · Author comment
I listed my starting length as 5.5, as I had always thought of myself as that, or a little less. But my first bone-pressed measurement was a little over 6", almost 6.1, so I really only think I gained 1.3". Newbie gains, although pretty impressive to me.
Recorded report · Author comment
Yes. The only rest days I take are when the petechial hemorrhaging builds up, after a few days of pumping. I sometimes get a little edema that goes away in an hour or two, but the darkening skin that Hinkle talks about is the little hemorrhages adding up, and eventually I give them a day off to heal.
Recorded report · Author comment
I set out to wrap a small heating pad around my penis for 10 minutes or so, but I must admit to sometimes forgetting to do this. I understand it is better for the ligaments, and I am almost certain that I am looking at ligament gains so far. My only real warmup is 30 seconds of "helicopter" before manual stretches.

I've gained 0.8" in 11 months of work - tons of people have gained 1.5 - 2 inches over the course of several years.
Recorded report · Author comment
All of my length gains have been from extending/hanging. I do pump as well though.
Recorded report · Author comment
I fucked up massively and bought the Size Genetics and then the PenimasterPro - huge waste of money. I've managed to make it work pretty well tho by modding the PenimasterPro with higher tension springs (up to 6lbs). If I could start over, I'd go straight for an Apex, or BestExtender, or HogStretcher (basically any extender capable of delivering high tension).
Recorded report · Author comment
The only thing I can suggest is getting an erection before you apply the vacuum cup - your glans will pack the chamber more fully when you're erect and this might reduce slippage as the cup has more to grip onto. I've never hung more than 4.5lbs with the Penimaster though, so I'm not too sure.

I have a bathmate in my closet since 2 years ago, I don’t use it because I’ve read bad things about it, like men that have had terrible injuries, and others eho had lost their erection function, so Im only using the penimaster extender, I think I will use the bathmate but very moderate, like 2 - 3 days a week and for less that 10 minutes each sesion

Before you check out

  • Confirm the exact model, selected size and included components.
  • Check the final total, destination country and current return conditions with the seller.
  • PRO Basic is the attachment. Check which traction components are included.
  • The weight expander is a hanging configuration; use its separate guide.
  • The manufacturer’s US listing specifies use under medical advice. Check the conditions for your market.

Questions behind the search

Before you decide

Are these PeniMaster PRO results?

They are the accepted PeniMaster family reports. Some source records name PRO, but the displayed group has not been independently split into PRO-only, Classic-only or configuration-specific outcomes. Read each report’s recorded device names and routine.

Is PeniMaster PRO Basic a complete extender?

Basic is the attachment portion of the modular PRO system. Check for the rod, belt or other traction component in the package. An attachment or replacement-part listing is not the same purchase as a complete system.

What is the difference between PRO and Classic?

The manufacturer lists Classic separately from the modular PRO range. The PRO rod and belt systems use the PRO attachment. Do not substitute Classic parts, specifications or reported outcomes for a PRO configuration without checking compatibility.

Where does the PeniMaster weight expander fit?

It is a hanging configuration, with a separate product guide linked below. This page does not relabel the brand-wide reports as rod-only, belt-only or weight-expander results.

Is PeniMaster better than PHALLOSAN forte?

The archive cannot establish that comparison. The people, routines, measurements and periods differ. Compare package contents and practical configurations in the Phallosan guide rather than treating differences in means as a product ranking.
