Do they really satisfy are research needs?

I know for research purposes we can get almost every powder available (e.g. testosterone all esters, trenbolone, clenbuterol, femera)
yet are research needs aren't statisfied seeing that some real popular medicines aren't available ---> Or are they?

Anyone ever came across one of these (for research purposes!):

3,5-diiodo-L-thyronine (T2) powder
Orlistat (Xenical) powder
Liothyronine Sodium (T3) powder
Phosphatidylcholine (Lipostabil) powder
4chloro1dehydro17alphamethyltest (Oral Turinabol) powder
Isotretoin (Accutane) powder
Ethylestrenol (Nitrotain) powder
Ketotifen powder

Just curious one how the world supplies are scientific needs

i have seen a couple of those, but please don't pm me asking where i've seen them, i forgot where and i don't keep records of anything

It's just amazing how underground labs have acces to these raw compunds and we don't.
