I just watched this video of a guy who claims he lost his gyno using nothing but turmeric powder and water. I figured it might inspire you to start using turmeric, you can check it out here:
Here are the key messages:
He uses turmeric powder + black pepper + water
He uses just 3 twists of his pepper grinder. A small amount of black pepper enhances the bioavailability of curcumin, the main active component of turmeric.
He followed the treatment religiously for 2 months
It's important to use any natural method like this daily for at least 2 months before you can expect to see results. Most people give up after trying something for just a few days.
After he stopped using turmeric, his gyno and puffy nipples never came back, even when he gained weight!
This can happen for you too, if the initial environmental factor that caused your gyno is no longer there.
Be warned with turmeric powders though, many have been found to contain lead and other contaminants that can make your man boobs worse. It's much better to take fresh turmeric root, which looks like an orange version of ginger. You can simply grate it into water and drink it.
Do it for 2 months straight, and see how you get on.
