If you cant and dont want to get any more than the one bottle you could always use it LOW dose to see if it helps with any joint pains. Your 47 so your probably have at least one or two by now. lol

Also as said. NO nolva, it will hinder gains and could drop your E2 to much causing other problems such as ED. Your on TRT so there is no need for PCT. Keep the nolva just in case you do start to get gyno but get some Adex to use on cycle to help make sure you dont. Before using the nolva for any reason do a lot of research so you know how to use it properly so you dont get E2 rebound or crush your E2.

Best thing would be to just put them away for now. Keep lifting for a while and learning then try to get another couple of bottles of Deca for later. For your first cycle you should just double your TRT and call it good. Honestly you will get good results if you are ready and your diet is in check. No need to add Deca or anything until cycle 3.
