I work out, too. When you are 20 years old, you won't have a high level of competition. If your level is not very high and your training intensity is not very strong, I suggest you not to use testosterone products first, because there will be some dependence. This medicine has a certain effect in terms of action. I don't know if you have sex. If the testosterone content is low after sexual life, taking this medicine will really recover faster, but after all, it is a medicine and there must be side effects!
In short, I suggest that you don't train too hard. If you don't have sex, don't take it first Just drink some protein powder. After all, 20 is still young!
