So I have some testostorone and some deca sittinng at home and they both expire the 1st month of 2016. I am certainly debaing weather I should just do test only or Deca since I already have it. I have been off cycle for about 8 months and the last time I used deca was over a year ago. Will I see a much bigger difference in gains if I use the deca vs test only and how bad is deca for you as it goes in the body. Keep in mind I also have caber in hand and aromasin,hcg. plus clomid for the end.
