I am abut to use a new TDS Test Base(Source from another board) is transdermal and it has good reviews from many guys on that board, these are meant for 4 to 6 week cycles and get in and out of the system real fast, absortion is 60% worst case scenario. Have done the injections I want to do something different this time, I am a little skeptical but I will give it a try.
Test Base is way more efficient than 4AD.
