From the last 20 years, it was invented in the 80s, and from the 90s people started using different products that came, and they went. We started using aspirin for anyone at the end we stopped because it was s good for nothing. Corticoids – it is all for nothing. DHEA supplements are good for nothing. Ubiquinol now is good for nothing. Don’t forget, it’s not a matter of nutrition, our latest diet is much more than we need, your grandparents had a lot of children, and their diet was far worse than yours. In Africa, they have a lot of children, in Bolivia, they have lots of children, and their diet is a disaster. Please, have a common diet, use a normal diet, be secure to have a healthy diet, but don’t think that there are products that you can add to get results. Melatonin is good for nothing or Curcuma, some articles are saying that it is good for semen, do you really think so? Please, don’t buy what people want to sell to you.
