My brother has decided to run a cycle of Sustanon and deca. Thats all the info he gave me. I assume he is taking Sustanon 250 and Deca-Durabolin. I did a little research and it seems that they arent the harshest ones out there but from our conversations he has no clue what post cycle therapy is and i dont think he plans on running one. I personally recommend a PCT for any steroid regardless of toxicity but how bad are these two stacked? How hard should i push PCT on him?
