I have doing research for over 5 years now on the exact science of gynecomastia.
When we eat food this food is transported to our bodies cells to replace the old cells. The old cells are transported out of the body via the adrenal system and lymphatic system. The spleen pumps by pressure of breathing or muscle contractions, as it doesn't have a pump it relies on motion. Without motion the lymph fluid slows to a halt.
Another system responsible for removing the old cells and removing them from the body is the Adrenal System. Which is either or skin via sweat or urination kidneys/ bladder/ etc.
So when someone has gynecomastia its actually an accumulation of dead cells which can't be removed from the body either by lack of sweat or other underlying infectious diseases.
One main point to getting these cells removed or why they aren't moving is because they may be in use by some time of "bad" micro organism which lives in dead cells and causes them to expand.
There are a number of ways to reduce and truly get rid of these excessively bloated lymph nodes. Because inside these lymph nodes is a continuous battle of our immune system fighting and attempting to remove the cells from the body. As I mentioned before there are numberous reasons as to what is occuring but one thing is for sure. Our bodies or all warm blooded mammals on this planet in fact, have what's called "phagocytes". These "phagocytes" are the process of our immune system fighting consuming/ eliminating/ and annihilating these "bad" micro organisms. Our "Phagocytes" can consume and eliminate even the toughest micro organisms including "Toxoplasma Gondii" from being around cats. The "Toxoplasma Gondii" and "Malaria" for instance live in our cells and breed in our cells. They both create cysts which mimic lymph nodes to protect them selves from our immune system. A cysts in our body can be felt if large enough and may harbor well over a billion micro parasites.
Here's a neat video showing our "Beastly Tough As Nails" "Phagocyte" tearing up several Toxoplasma critters which come from cats.
Anyway so with processes in mind like "Phagocytosis" as well as other processes like "Apoptosis" among others. The process of eliminating the cause directly without Medications and other things. Another MicroBiological study I read clarified "Androgen" hormones reduce the amount of "Phagocytes" in our blood. Rather than reducing them, the phagocyte has an androgen receptor that will causes androgen hormones to bind to them deactivating them. This is important for a women to have a successful egg development etc for life.
So one more thing to think about is "Phagocytosis" requires the use of "Reactive Oxygen Species" because these "Reactive Oxygen Species" kill/ consume/ eliminate "bad" micro organisms. Reactive oxygen species in Biology and Science just a simple "water" molecule and an "oxygen" molecule which when bound scientifically create "h2o2". Water in itself has no combustible attributes, yet once the "oxygen" is bound to "water" the molecule now becomes combustible.
Now we know how powerful "h2o2" is because it's being used by our bodies immune system already. In fact all warm blooded mammals as well as many other species phlyums have the presence of "reactive oxygen species" to aid in proper ideal health and well being. Reactive Oxygen Species and Phagocytosis are two that work together and without one the process cannot complete in an ideal manor.
Basically now I'm to the point. From what we understand now about the science of why Gynecomastia is really just Lymphodema/ Lymphoma.
How do we get rid of Gynecomastia?
Since there are minimal studies and most it all relies on our Pharmaceutical Companies who do what better than anything else they do? MAKE MONEY.
Here's something about "Reactive Oxygen Species".
With use of Reactive Oxygen Species and Phagocytosis these two will work together to even kill so-called "healthy" human cells which are actually infected with a micro organism parasite. When that happens the cell may appear healthy but once that cells reaches our tissues it doesn't do us any good. But rather does us harm, so it must be killed and carried out as waste via the lymph system/ adrenal system (Sweat, Urine).
So we know we have gynecomastia and why isn't it going away? It's a number of things but the primary things are lack of significant sweat activity in the area. As well as too much "Sugar" in the blood which gets carried to the congested area and "Feeds" the organisms that reside in the area.
That explains why when you drink soda and sugary drinks the gynecomastia tissue swells. If you were to go a month without soda and ultra sugary drinks and only organic juices smoothies, NO TAP WATER, and only drinking Distilled water. The tissue swelling goes down completely! That tells us we know what we need to avoid to keep swelling down. At that point its important to lose weight, and with my experience I had to stop eating meat and go vegan. Weight loss came automatically. I'm not telling anyone to go vegan but this is something to consider. This guy in this video is not me and I'm not a "vegan douche" like this guy. I say do what makes you happy and if meat makes you happy then I'm not going to tell you to do anything you don't want to. http://www.youtube.com/watch?v=XUCTfSKtRms
Anyway in regards to reactive oxygen species, I was thinking of what would really work! A true solution but needs to be precisely safely and carefully! Gynecomastia as we know doesn't go away no matter what we do for no matter how many years.
Injecting Reactive Oxygen Species into the Gynecomastia tissue
1) syringe (ultra clean and made sure to be 100% sterile).
2) clean site with 91% alcohol and let dry.
3) feel where the tissues is most dense.
4) inject an ULTRA tiny amount of the tissue. We are talking 0.050cc of h2o2.
This is only experimental but science explains it all and it's just like supplementing h2o2 directly at the site of where it's needed most. This way our phagocytes don't need to kill or consume the devastated bloated lymphodes/ but rather it can easily send them off to the adrenals to leave our body! In short time literally it should all be completely gone. As long as your exercising stimulating your lymph flow and injecting very tiny amount of h2o2 in the site.
I'm not trolling or anything just sharing my knowledge and experience.
