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.

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

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

And from 11.5 cm MSEG to 12.25 cm MSEG.
Clamping, pumping, gua sha scraping, massage gun, almost every day. Occasionally using penis master pro extender for 1 hour.
Ever since I added clamping to my routine my gains became easier to come.
Last time of any PE activity was 2 days ago.
In reality the 1st measurement is the wrongly performed one
The 1st part of 1 picture is my initial measurement in October.
2nd measurement is for easier comparison with the first. 3rd is the correct measurement.
I don't like the vacuum cups.
I also use an IR heat lamp.
Thank you! I raise my hat for your gains too, those are a lot more impressive! Let's keep growing our dicks

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

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!
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.
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.
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.
All of my length gains have been from extending/hanging. I do pump as well though.
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).
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 the penimaster and I think I’ve gained half an inch in about 1 month
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

Currently 7.44 BPEL
Already gained .20/inch in a little over a month by hanging at only 6lbs x 2-4 hours, then 3lbs in ADS for 4-6 hours, then pumping for 30-40min from 5-10inHG daily.
Phallosan forte ADS
Penimaster Pro
LeLuv pump
Today is day 59. For pumping today is day 30.
This was for about 2 years. Then i stopped again for about 2 years. Gains stayed this time.
That took me from 7.1-7.44 in about 60 days.
Got it back by wearing the Phallosan forte ADS
phallosan forte, penimaster, and jelqing for about 3 months and got up to 7.2bpel
Now I’m up to hanging 6lbs x 6hours. Phallosan forte or Penimaster proADS when possible. 10min recovery pumping in the morning, 30min hard pumping at night.
JP90 newbie routine for about 6 months. Went from about 6bpel to 7bpel Stopped for about 4 years. Lost the inch.

Our product assessment uses the sources below. Seller claims about gains or safety are not substituted for GainAtlas’s community data.
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.
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.
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.
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.
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.
