Bionabol is the trade name for methandrostenolone manufactured by Balkanpharma in Bulgaria. Bionabol was discontinued in 2005 and is no longer in production. Bionabol was not renewed with the Bulgarian Ministry of Health for production, therefore the last batches of Bionabol were made in 2005 with a 2009 expiration date. Bionabol is methandrostenolone which is the generic name for dianabol, the most popular oral steroid in the history of oral steroids. Dianabol was originally manufactured in 1955 in the United States by Ciba Pharmaceuticals. Bionabol is a derivative of testosterone, but altered for a more anabolic effect with less androgenic side effects, as well as being able to be taken orally. Average dose for athletes using Bionabol range from as low as 10mg per day, all the way up to 100mg per day or more for adventurous athletes. With Bionabol, more is not necessarily better. Side effects increase dramatically with increased dosage, which include and are not limited to: water retention, liver toxicity, acne, aggression, and increased blood pressure. Bionabol is best when used in conjunction with injectable steroids such as deca-durabolin and testosterone. Duration of cycle is generally 6 weeks or less to minimize the side effects and damage to the liver. Best results will come from low dosage cycles for longer periods of time instead of the usual recommended high dosage short term cycle to "jump start" your cycle until injectable steroids accumulate and begin working in your system. For instance, Bionabol could be taken at a dose of 10-20mg for an 8-10 week cycle in a very safe manner for more permanent gains, instead of the usual 50-60mg per day for 4 week cycle, which leaves the user with nothing more than massive water retention that quickly subsides upon cessation of the product.
