you can get 5mg and 10mg they have BD stamped on them, usually means british dispensary, they also have a funny snake wrapped round a dagger or something like that stamped on the other side, if its a pentagon shape then its 5mg british dispensary, if its 10mg square shape then its british dragon. both are pink, both are good. never heard of a 45mg, either its fake or youve been misinformed.
