Baby Chee, sorry, I was a bit fast with that response.
Not storing cultures, lipases, rennet etc in the fridge or if freeze dried powders, in the freezer, is a reasonable mistake when first starting out, I've made way more/worse
So since you ordered, how long has it (they?) been sitting at room temperature and what is your room temperature?
They are shipped without refrigeration, so they don't have non-refrigerated "half life" of days, that said, more experienced people than me should be able to tell how degraded they are and how much extra you should add to compensate.
