I was found with low testoterone levels have bern taking testostetone injections every 2 weeks for 3 months then once a month is this bad for health?

See endocrinologist: Low testosterone is overly diagnosed in the US because of all the commercials on TV. Most men on testosterone should not be on it. The longer you stay on it, the more your body becomes dependent on it. You need to find out if you really should be on it at all. You need more than a low testosterone to diagnose hypogonadism. There may be a higher risk of heart attacks and strokes while on it.

Depends: How low is low? What symptoms did/do you have? Was your level checked at least twice in the morning? Were your levels really low or just low normal? Remember that we're here to treat you, not your numbers. Injecting once weekly is old school. You run risk of excess levels & resultant side effects. We recommend weekly injections of smaller doses to minimize ups & downs. Close monitoring is required
