ndriol comes under the names Androxon, Understor and Restinsol. Andriol is an oral steroid and it`s presented in little, oval-shaped, red capsules. An oil, which contains the testosterone, is inside of these capsules. Andriol is a unique steroid in that it is not an alpha alkylated 17 steroid. The only bad thing about this base is that it only allows the testosterone to remain active in the system for several hours. Thus frequent administration of the capsules is necessary. Aromatization is minimal with this agent.
