hey, i'm from singapore. i've been trying to find out the legal issues regarding aas in my own country more out of curiosity and if something unfortunate were to happen to me.
safe to say from my findings, aas is not regulated under the singapore narcotics. they are more concerned with finding other hard drugs like coccaine, heroin, marijuana, the normal drugs you'd expect. however, thats not to say its not regulated here. aas is actually classified under the poisons act. to give you an idea what that means, yohimbine is also under this act. thus, this puts the regulation of aas under the Health Science Authority of singapore. under this act, importation of aas is illegal and the storage, distribution and importation with intent to SELL is an offence.
so with as much as i can gather at the moment, its ok to possess as long as its a personal stash. i could be wrong though so take it for what its worth. you should visit
www.hsa.gov.sg
but in the local scene, its not that hard to acquire it if you want. and we dont have steroid busts or stuff happening here.
