high mg

i see some vendors on other site sell 1000mg EQ and 1500EQ/tren blend.... is this for real and wouldn't it be very painful?

i see mutagenic and hulk body that have this high mg gear and i just wonder is this stuff legit and doesnt it hurt like hell? i seen these places that have test p that was like 250-300mg? oouch that shit has got to hurt. or these ones that are 1000-1500mgs? if that can be made without...
