they're fine. They have decent prices, they are international so stuff passes through borders and customs. Though they say they accept WU and MG, I'd bet they make you do their wire transfer method. But maybe I'm wrong and they are taking WU/MG again. They will deliver though. Could take anywhere from 2-6 weeks, but you'll get it if customs doesn't.
International sources are usually cheaper, but a lot of guys go with domestic due to not having to risk having a pack seized and possibly getting your address on a list. Though their HGH is higher than a domestic source I know of!
