I’m not convinced even an inch in length is possible for most people, although I think for some it may be possible over a long period of time. I researched PE for months and found the evidence accross all PE forums to be very unconvincing. I do not think any girth gains are possible outside of EQ gains and swelling. You will have people tell you otherwise, but track their old posts. Most will have started with ED, young enough for late stage puberty, lose all girth gains over an extended break, have big claims but no pictures to document their progress, sell sone type of PE related equipment, claim they didn’t take accurate or any starting meaurements, ect.
Jelqing distened my dorsal vein in only 4 sessions at moderate grip and 10 minutes maximum duration. I stopped early and have no significant loss on function, but my vein has not fully returned to normal. Just realize their are risks and others have been hurt doing proper technique.
I bought a pump because there are studies that show they are relatively safe when used with caution. However, no real length or girth gains occurred in either study. Wikipedia takes a quote out of context from a study that used pumps to straighten the penis curvature due to peyronie’s disease making it sound like the pump actually lengthened the penis. When you actually dowload the study from a journal database and read it the researchers clearly state that the increase in length was due to and only correlated to the straightening of the curve. If you unbend a curved rod and measure it with a ruler at it’s furthest displacement you would expect the rod to measure longer without ever growing simply because you straightened it. This study used a protocol similar to avocets routine; two 10 minute pumping sessions everyday, but still had no gains in girth and only straightened the penis. Haven’t used my pump and I don’t plan on it because when unbiased researchers used it the same way we do, they saw no results. I plan on selling it.
