Sorry but StressZyme does not have live bacteria or Bio-spira in it. Only Bio-spira is live bacteria and must be kept refrigerated. It is the only product that produces an instant cycle that I am aware of that is available in the States at the present. There may be another but where it is available I am not sure of. Someone posted about one that she used but I do not know where she is located if in the States or out. It is used the same as Bio-spira though.
StressZyme is a compound that is supposed to relieve stress in fish not cycle the tank. The only ways to cycle the tanks are to go through the cycle process as described in the
nitrogen cycle article at the beginning of the homepage:
http://www.fishlore.com/NitrogenCycle.htm (either with fish or without) or with the Bio-spira product.
Cycle and other products that say they will cycle your filter with "live bacteria" that are kept on shelves and not refrigerated contain an entirely different strain of bacteria and are not stable and are basically useless and a waste of money.
Pet store employees that try to sell such products to you with the promise of a quick cycle are only interested in making a sale and do not care if your tank cycles or not. Do not trust what they tell you.
It is true that the use of gravel or a piece of filter media or an old filter pad from a cycled tank will help to cycle a new filter very quickly in about a week to ten days. Even transferring a large piece of decoration from the cycled tank for a couple of weeks will help. Anything that the bacteria has grown on will help to speed up the process but not be an instant cycle.
