Nitrotain is the paste form
Nandoral is the tablet form

Ask your vet about it, as they will be able to get it for you.

I dont know dosage but on Nitrotain i give mine ''a matchstick head'' worth (altho the recommended dosage is .13ml) i have ha no issues at all regarding them coming on season. And so im told with the tablets, its usually 1 or 2 per night in the dinner.

After a bitch of mine was on Nitrotain, and went off BADLY. Dropped form, lost her usual spastic attitude and clearly hated everything i took her off the hormone an she came back to her normal self. Suits some bitches, some hate it so dont be disheartened if your girls drop any form.
