There must be different charts for cyclists and normal people
When I had problems with Low test I bought testosterone boosters. It helped me a lot.
According to https://naturaltestosteronepills.com:
"Testosterone boosters are a class of herbal supplements aimed at naturally increasing your testosterone levels. They can work by directly increasing testosterone or by inhibiting hormones responsible for converting testosterone to estrogen. Either way, in the end, these supplements are meant to help you recover faster and build bigger, stronger muscles."
