This is a trt/mens health forum. If I understand you correctly and by course you mean cycle as in steroids we do not give advice on testosterone/aas use regarding cycling or blasting/cruising. There are many other steroid forums who will be more than glad to answer your questions. If you are suffering from low t or hormonal issues or are on trt and looking for advice/guidance or anything related to mens overall health than there are many on that would be more than willing to help you.
