does anyone know/use the research chemical pct you can buy over the net?? are they just as effective.? they come in liquid form and they're alot cheaper then the regular aas sources.. ive got some nolva and clomid from one vendor and just started taking it.. my source was totally out of nolva and clomid so i took a chance and bought some.. i also noticed they carry liquid clenbuteral and was a little interested in that.. please let me know if you have some info
