I've used alot of both and I like test eth dived in 2 weekly shots, your sus250 is a combo of 4 test esters that have differnt lenths of time they work and lots of people love it for once a week however it always causes me and others I know a fairly painful spot at the injection site, on me that would be my thighs, after my sus 250 shot my thigh would be so sore I couldnt work them very much and with 2 + ML I could barely walk for about 4 days.
