Stress Zyme....useless or helpful?

[EVP]

Do you guys think this product or ones like it are completely useless or do they help strengthen BB?

I've considered it to be useless, as are most similar products. Even something like Bio Spira which some people swear by, and I've had no problem with, is something I still view with a distrusting eye

Useless IMO...
