Have been asked what type of injectable testosterones are available? Most patients get cypionate or enanthate and last from 1-2 weeks. Undeconate (Aveed) lasts about 10 weeks. Many are unaware of propionate which can be given 2-3 times a week. It is partly because it is harder to obtain propionate these days.
