Also under the brand names Androxon, Understor and Restinsol. Andriol is a revolutionary steroid because, besides methyltestosterone, it is the only effective oral testosterone compound. Testosterone itself cannot be taken orally and is deactivated by the liver. Andriol aromatizes only minimally, meaning that only a very small part of the substance can be converted into estrogen. The users of Andriol therefore do not experience feminization symptoms such as gynecomastia or increased body fat Andriol comes in 40 mg capsules . This is an oral steroid and it’s presented in 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 Andriol is a natural ester added to a synthetic derivative which will not change liver enzymes. No testicular shrinkage, no reduction in spermatogenesis will occur with reasonable dosages.
