If you are referring to coming off of a heavy androgenic compound and bridging to a mild anabolic.....I would go with winny, var, primo; that is what Im about to do here shortly.
wouldn't a low dose of test be the BEST bridge.. i mean.. anything else is just going to suppress test.. by low dose i mean like 100mg a week.. or possibly less.. nothing to cause major gains.. and along with HCG.. you can do this pretty effectively.. i think using primo or var for a bridge would just keep you shut down and is gonna hurt you in the long run... just my 2 cents..
