The supplement you are referring to is completly different from TESTOSTERONE CYPIONATE which is an injectable AS. What you are referring to is a pro-hormone, and the injectable is an AS. As for injecting 1-AD, why would you want to. And they tried an injectable form of 1-test, but it caused a horrid burning sensation at the injection site. My suggestion to you would be to try a 1-testosterone-17-ß-undecanoate such as 1-TU because it has the same delivery system as Andriol, and is the only delivery system that has been tested and approved to be effective. The other delivery forms may be just as, or more, effective, but have never been tested, so my advice would be to stick with what has been proven to work. I would also choose this over the 1-AD, as it still has to be converted once in the body. If it is just going to be converted to 1-test anyway, why not just take 1-test?
