reason is...
that you buy it from the doctor that scripts it for you and he will charge you an arm and a leg for it and he will make a ton of money on you. At least that is how my friend gets it. he gets the script from the Doc. and the Doc also sells him the HGH. But the plus to all that is that the doc. will also script him, test, arimidex, and anavar, and anadrol, clomid, nolva...(anything legal to buy with a script)
