In my opinion, the best product for testosterone supplementation is testosterone-based products. A testosterone supplement has a low concentration of testosterone and high levels of estrogen and estrogen-like steroids (estradiol and progestin) and their metabolites, all of which are involved in male sex characteristics. For example, men who have low levels of testosterone have reduced sex drive, acne, high cholesterol, diabetes, and hypertension. In addition, there is a substantial risk of cancer. It is recommended that men take testosterone supplements for up to six months, but a more accurate period of testosterone supplementation is 12 months.
Most of the testosterone-based products have low concentrations of testosterone, so you should test out the products on a testosterone blood test before starting to take them. I recommend a test every 2-3 weeks and then you can proceed to the rest of the articles on this site.
Some testosterone supplements have more estrogen than testosterone and can cause negative effects on your body. A male who has very low testosterone levels, for example, may have an increase in prostate cancer and some of the symptoms of prostate cancer are: weight gain, fatigue, muscle loss, hair loss, or loss of facial hair. These can be dangerous if you have been taking testosterone.
