Anadrol-50 can be prescribed for severe anemias--the problem is the price and very few insurance plans will cover it. I don't prescribe it any more, for I have had to entertain calls from pharmacists asking me to explain why I chose it over Test or Deca or Oxandrin.
Oxandrin is now the most prescribed AAS, and it is used for Involuntary Weight Loss--because of HIV/AIDS; trauma. never had a pharmacy question this script; again, it is expensive, and not many insurance companies will cover it.
Test cyp prescriptions are never a problem. Enanthate and Prop are problems, for they are rarely prescribed and therefore, they are usually not on the shelves. Many pharmacies will not special-order unless they get a huge order, and the customer prepays.
Deca is available and is prescribed for Involuntary Weight Loss as well. It is about three times more expensive than Test, but much cheaper than the others above. Again, most insurance companies won't pay for Deca.
Winstrol is available in 2mg tabs at the pharmacy--this is USELESS, so i don't prescribe it.
So, Test cyp and either arimidex/femara/aromasin is the way to go with pharmacies and insurance companies. If the insurance company isn't involved, then paying retail prices will get you all of the above. Just my $0.02
