Bio-identical Testosterone Pellets contain the pure hormone, testosterone, that is dissolved and absorbed directly from the pellet into the blood stream. The testosterone is not immediately converted to the byproducts (Estrone/DHT), which can cause prostate swelling, hair loss, belly fat and a requirement for more and more testosterone. Other forms of testosterone are delivered in a form that causes blood levels to rise and fall drastically between dosing. Pellets are dosed two to three times a year which allows blood levels to remain quite stable.
