Testosterone is a naturally produced steroid from the androgen group and is found in vertebrates, birds, reptiles and mammals. In mammals, testosterone is made in the testis of males and the ovaries of women, although small amounts are produced by the adrenal glands. It’s an anabolic steroid and a critical part of the sex drive in men. Testosterone plays an amazing part in the development and overall health of the male reproductive system as well as important roles in the areas of increased muscle and bone mass, body hair growth, osteoporosis prevention and much more! As we age, men are unable to produce the amounts of testosterone needed to maintain muscle mass, strong healthy bones, increased sex drive and much more! A high quality sublingual like this one from DesBio can help to resolve some if not all of these issues. Directions: Take 1 - 10 drops under the tongue, 3 times daily or as otherwise directed by a healthcare professional.
