Not approved in the US. It is a long acting testosterone injection that can be effective for 8-12 weeks. It costs about $150 per shot in Mexico so expect higher prices in the US
Testosterone undecanoate injections are known as the brand name Nebido around the world. In the United States it will be called Aveed. Aveed is currently under review for approval by the FDA. This ester may stay longer in your system so that less frequent injections may be needed. The injection is usually given once every 10 to 14 weeks, though the frequency will depend on your individual testosterone levels. After your first injection you may be asked to come back for another injection at week six. For use in the United States, the company claims that only five injections a year are needed (compared to 48 injections per year for a 100 mg per week regimen). In other countries, a large injection dose of 1000 mg are allowed. The FDA did not allow the manufacturer to use this dose in studies done in this country due to fears of side effects.
In an open-label study which enrolled 130 hypogonadal men with blood total testosterone levels below 300 ng/dL at study entry, Aveed was dosed as an intramuscular injection (750 mg) at baseline, at week four, and then every 10 weeks throughout the remainder of the 21-month study. Approximately 70 percent of patients completed all injections and 94 percent of them had total testosterone from 300 to 1,000 nanograms/ml through the entire study.
After Nebido was approved in Europe a small number of European patients experienced respiratory symptoms immediately following an intramuscular injection of 1000 mg in a 4 cc injection volume, (versus the 750 mg, 3 cc injection volume used in the United States). The makers of Nebidobelieve, and the FDA concurs, that the reaction is likely the result of a small amount of the oily solution immediately entering the vascular system from the injection site. This known yet uncommon complication of oil-based depot injections may be related to inappropriate injection technique or site.
The problem is characterized by short-term reactions involving an urge to cough or a shortness of breath. In some rare cases the reaction had been classified as serious or the patient had experienced other symptoms such as dizziness, flushing or fainting. In U.S. clinical trials of Nebido 750 mg (3 cc injection volume), the proposed dose in the U.S., there was a single, mild, non-serious case of oil-based coughing.
The U.S. manufacturer, Endo Pharmaceuticals, is gathering data to address concerns about the respiratory symptoms. It is not known how much longer it will take the get this product approved in the United States as of June 2010. And even if it gets approved, it may not be widely available for people to buy through private health insurance if the company decides to price it as high as gels.
