Just like physiological gynecomastia, the incidence of idiopathic gynecomastia has also been increasing dramatically over the years. Although science hasn’t found a definite causal link with gynecomastia, it’s blindingly obvious to anyone who’s willing to do a bit of research, that rates of gynecomastia are increasing for the same reason rates of breast cancer are increasing in both men and women, and the same reason rates of obesity, prostate cancer, various other cancers, endocrine disorders like thyroid disease, diabetes and huge hosts of other diseases have been increasing in the last few decades.
A lot of it really depends on the amount of caffeine in the drink. If you read my comments below, you’ll see how much caffeine it takes to increase your cortisol by 30%. You have to remember that supplement companies, in general, don’t care about your health or even your performance. What they care about is that you “feel” something when using their product and therefore you “believe” it’s doing some good so that you come back and buy their product again and again. That’s not to say that caffeine doesn’t have performance benefits because the literature is very clear that it does, but it’s a double-edged sword. So you have to weigh the pros and the cons with it and decide for yourself if it’s worth it based on your own individual performance and body transformation goals.
