estosterone replacement therapy (TRT) is available in several forms including skin gel, shots, long-acting pellets, patches and pills. Testosterone can be injected directly into the muscles, or implanted as pellets in the soft tissues, or taken orally in the form of pills. However, these can have negative effects on the liver.
Other side effects of TRT include acne (pimples), breast swelling or soreness, swelling of the feet or ankles, decrease in the size of testicles, and infertility.
Apart from external TRT, there are supplements, commonly known as natural testosterone boosters, which can enhance your testosterone endogenously. Increased level of testosterone in the body can lead to increased lean mass, reduced body fat, and more strength. Hence, it is safer to use natural testosterone boosters as they essentially have many of the same benefits as Androgenic Anabolic Steroids (AAS) use or TRT without the negative side effects.
