Oral Steroids are considered to be those types of steroids that are administrated orally. Orals are very popular among bodybuilders and athletes due to the fact that being in a pill form, they are very easy to be taken and more specifically to be ingested.
When using oral steroids the risk of infection is minimized because one does not need any auxiliary equipment or any precautions for keeping sterile the whole process of injection. Oral steroids are fast-acting and provide fast results, thus they are preferred by users that expect quick results.
Orals are considered very hard to liver, especially those oral steroids that are 17-alpha alkylated, so many experienced steroids users prefer to take them in combination with injectable steroids. The 17 alkylation is added to improve the bioavailability of oral steroids. Without this chemical alteration, drugs may not be able to survive the first-pass metabolism of the liver, and thus may not be able to exert anabolic effects.
It is highly recommended to take post cycle therapy after stacking with orals, in order to rehabilitate the damaged liver.
