Andriol is one of the few new steroids developed in recent years.

Andriol is a revolutionary steroid, because next to the methyltestosterone, is the only effective oral testosterone preparation. Testosterone alone loses efficiency in the oral form, because it is absorbed by the portal vein and immediately inactivated by the liver. The active substance testosterone undecanoate contained in the andriol is absorbed from the intestine into the lymphatic system, without having passed through the liver. This fact causes its efficiency even with the oral application. Liver function is not affected. Testosterone undecanoate is fatty acid ester - natural androgenic testosterone and it change in the body into dihydrotestosterone - metabolite of testosterone. Due to this fact there is a minimum aromatase with andriol (a very small part of the active substance can be converted into estrogen, since the dihydrotestosterone do not aromatase, only during the long-term use of high doses. Andriol has only low inhibitory effect on the hypothalamus, thus affecting the secretion of LHRH (luteinizing hormone Releasing hormone) completely negligible.
Testosterone undecanoate is in the body very quickly absorbed and expelled in the urine. Capsules are effective only for a few hours. Women should forget to use andriol, because even in this preparation (like testosterone) are androgenic component strongly represented. The potential adverse consequences of the use of andriol can be high blood pressure, fluid retention, acne, excessive sexual stimulation and women could have virilization symptoms. Andriol should be stored in a cool environment (6-15 ° c), preferably in the refrigerator. Capsules show a very low resistance to heat, and exposing to the sunlight can cause damage.
