I'm coming back from a bad back injury where i tore some back muscles. I was thinking about doing a cycle of the peptide tb-500 to help recover. I was wondering if anyone knows the difference between that and corticosteroids? Im still new to all this and they sound similar. I got really bad side effects from prednisone like bad anxiety and depression. I obviously dont want to go through the same thing with TB-500. If anyone who has taken a cycle of this coul list any side effects i would appreciate it. Also was wondering if pct is needed after doing a cycle of TB-500? Im pretty sure you dont but I'd rather be safe and ask.
