boxcar23 gained 24 cubic inches. He was in his late 70’s during his gainer period here, and was an active poster, giving many details about his routine and theory about growth. He was not very sure of his erect starting size but he estimated it at 5” x 4.5”. He finished at 7.75” x 7.25” which is a gain of 2.75” length and 2.75” girth. It’s likely he did most of his PE from about June 2001 through March 2003. It’s possible he tried some PE as early as 1993. He hasn’t been around for a few years now.
Boxcar23 was a general pediatrician for his occupation, so he contributed some good info into the theory of cell growth in the penis, penile health theories, understanding of kegels, penile nerves, as well some good stories about turning heads in the medical community when he “proved” to them with definitive evidence that PE is real. As a physician he believed that age was a factor in his gains, citing lower elasticity in the tissues.
It seems he enjoyed his increased flaccid size more than erect size (in my 70’s I bet I will too) and went to the nude beaches in Jamaica. A lot of the measurements he quotes vary between flaccid and erect, and between whether they are immediately post-workout or not. So when reading through his individual posts, it’s not always clear on his growth progression. I would like to think as a man of science though, that his overall gains are quoted in the same state as they were initially measured.
He started out for the first couple months with half an hour jelqing and stretching daily, and then added in a Bib hanger and uli’s and squeezes for the next 6 months. There is a lot of variation in the measurements he posts during this period, but one thing is for sure, he gained length and girth very fast over the first 6-8 months using these exercises. His flaccid length started in the range of 3” x 3” to 5” x 3” and quickly went up to the 5” x 5” to 7” x 6” range. He attributes most of the gains to the hanging during this period
After about a year of that he updated his routine to 20 minutes of hanging (about 15-20 lbs BTC) followed by 20 minutes pumping at high pressure (10-20 inHg – important: he did not feel pain at this pressure while most people would) with 3-4 jelq sessions of about 100 jelqs each between about 5 minute pump sets, as I read it. Then he finished with 20 minutes of slower high force jelqing.
His rest schedule and overall time for each session was about a hour per day, 5 days a week. He estimated on average he did 500 jelqs per day.
His growth theory advocated using higher forces, but he also says that he didn’t feel pain, or that he felt a “pleasurable pain” so he was using that as an indicator of acceptable forces. He thought it was very important to use an overhand jelq grip and start the jelq as close as possible to the pubic bone. He has one post “Mouse under the Rug” where he outlines an interesting technique of kegeling and manually “pinching” off the bulbous area of the penis below the balls. Apparently he was able to get good girth expansion in this way, including a girth workout for the “internal” penis that is surrounded by the scrotum and usually so difficult to work.
Mouse under the rug
All in all, boxcar23 had some amazing gains, and contributed a lot of good info on how he thought those gains happened from a medical standpoint. There is considerable variation in his measurements, but that is expected at the age of 79. His age probably played a role in his success as well, but he attributes most of his gains to his early hanging, and then his jelqing/stretching through his career, and finally adding pumping about halfway through.
If you want to read some more details about his routine and size progression, do a search on the threads that he specifically started. He made a thread every once and a while with updates on his gains and routine.
