Before you even read any of this, you need to know exactly where you stand. Don't use rough guesses or ego measurements here, this is data and global / regional percentiles.
If you don't know your exact bone-pressed and non-bone-pressed measurements, or what percentile you actually fall into globally, stop coping and go find out right now. You can't track your growth if you don't have an accurate baseline.
The Origin
I’ll be straight up about why I started this years ago. It comes down to mostly these three things:
I read a lot of adult manhwas and stories. The main characters almost always have the exact same stat line: handsome, rich, dangerous, and packing a massive dick. I just decided I wanted that exact stat line in real life, as much as I could.
I’m 5’9 barefoot. Good for a Filipino, but I don't like getting mogged by foreigners. You can’t change your height, so I made the conscious decision to max out everything else to compensate for it, most especially my dick.
Let’s not lie to ourselves. The urge to dominate and out-size the next guy is hardwired into every man's brain. So yes, self-explanatory.
How I Found It
I was bored with nothing else to do, late into December of 2021. Cebu was still recovering from the recent Typhoon Odette that hit, most of Cebu was still not powered, but at this exact time we were.
Anyways, as I said- I was bored and I had just finished reading another adult manhwa with the same exact bullshit oversized character always in manhwas. So because of that, I decided to search for actual ways to enhance naturally and ended up on Reddit. It started at r/AJelqForYou, but minutes later I found r/gettingbigger, and the rest is history.
NOTE: I didn't stop naturally growing till I was around 19. So for the first 2 years of coming to light on this knowledge I didn't take any routines seriously, just on and off. So I don't really count any growth from the first 2 years. The last 2 years of the past 4 years is what counts. The starting 70th percentile measurement is from 2024.
The Proof
Before we get into the anatomy and the actual routines, let's look at the clinical data.
This isn't just theory. An actual study was conducted by a doctor tracking participants over a 6-month period using these methods. Across the board, the average growth for participants in just half a year was:

Anyways, here is exactly how it works.
The Basic Anatomy & Why It Works
Let's keep this simple. I’m not going to bore you with a medical textbook, but you need to know what you are actually working with so you don't just pull on your dick blindly.
Your dick is basically made of two main parts that actually matter for this:
Inside your dick, there are two main chambers. Think of them like long, hollow sponges. When you get hard, these sponges fill up with blood. The bigger the sponges, the thicker you get. This is what dictates your Girth.
This is the most important part. The sponges are wrapped inside a super tough, fibrous sleeve called the Tunica. Think of it like a thick leather tube. It doesn't matter how much blood pumps into your sponges, if that leather tube doesn't stretch, your dick stops growing. The Tunica dictates your absolute maximum Length and Girth.
Why It Actually Works (The Science)
This isn't magic, and it’s not some scam pill. It’s basic human biology. It technically works almost exactly the same way bodybuilding works, or how indigenous tribes stretch their earlobes and necks with rings over time.
Here is the exact mechanical process:
- Plastic Deformation (Creep): When you apply consistent, targeted tension (pulling for length) or pressure (clamping/pumping for girth) to the Tunica, you force it past its normal elastic limit. You are essentially creating micro-tears in that tough leather casing.
- Cellular Division: Once you create that mechanical stress, your body goes into repair mode. It sends new cells to heal the micro-tears, building the casing back slightly longer and thicker than it was before to handle the new stress.
- Smooth Muscle Expansion: At the same time, the sponges inside are forced to adapt. They stretch out and grow more smooth muscle to fill the newly expanded casing, allowing them to hold way more blood.
You break the casing down with calculated tension, the body rebuilds it bigger, and your maximum capacity expands. That’s it. That’s the entire secret.
The Routines (Length & Girth)
I’m going to keep this part incredibly compact. I don't use devices, and I didn't drop hundreds of dollars on equipment to hit the 99th percentile.
If you want to spend money on traction devices, extenders, or pumps because you think they are faster or more effective, you can go do your own research on the subreddit. I kept my routine purely manual. It costs zero dollars, you just need your own hands and daily consistency.
This one guide covers everything you need for both Length and Girth manuals, with pictures. Read it, study it, and execute it:
Personally though, for length all I did and still do is straight down an hour a day. Just wanted to do something simple and convenient.
The Ultimate Cheat Code
(FAT LOSS. NOT WEIGHT LOSS.)
If you take only one thing away from this entire site, then let it be this: Focus on FAT LOSS, not weight loss.
Every guy has a fat pad at the base of his pelvis. Depending on your body composition, you could literally be hiding a massive % of your usable dick underneath a mound of pelvic fat that you didn't even know existed.
This is even more critical for us FILIPINOS. Genetically, Southeast Asians and Austronesians are highly predisposed to "localized fat accumulation." What that means is, our bodies specifically prioritize storing fat directly in the lower belly and abdomen. You could have skinny arms, a slim face, and look totally normal in a shirt, but still have an inch or more of your dick buried under that localized lower belly fat.
I’m speaking from direct experience here. Trimming down from 80kg to 67.5kg over just a few months with pure diet made me lose a significant amount of weight FAST, but I was lacking the protein in my diet to sustain any muscles - so a large portion of the weight that came off was from my muscles. I figured this out cause my fat pad barely moved, and my lower belly still had a lot of fat around it.
At 67.5kg I started switching my diet to high protein low calorie, like literally 1000 caloric deficit with 100g+ of protein to force target fat, I consistently measured my waist and checking my fat pad measurements to know I was actually losing fat this time. And yes, eventually it started to shave away mm by mm. I'm not really able to exert myself at the moment so that's why this is all purely diet. If you can work out, it'll be much easier and faster to lose fat paired with a good diet.
The trick isn't killing yourself with cardio, I stripped that weight off entirely through pure, absolute dietary discipline while remaining physically inactive. You cannot out-train a fat pad; you have to starve the fat out through strict diet.
Drop the lower belly fat, and you instantly unlock whatever length is currently hiding in your pelvis.
