Jubei, sust for me has less acne, less water bloat than cyp or enant. Although, I prefer enantate over cyp for the same reasons. I like prop (which is why I like sust), but just prop SEEMS (subjectively) to give me less gains than the longer esters (maybe the longer esters just build up a higher blood level more effectively, I don't know.) I know guys say, "Oh! just do enantate and prop." Sure . . . and tell me again how that's easier than sust? Plus, I seem to pay 10-16$ for 200mg test whether prop, enan, cyp, or sust -- so where is this supposed cost difference? Sust has always been cheap, far cheaper than prop, and only slightly more expensive than cyp or enan jugs. Also, sust is human grade, except for schering, all these other esters are UG labs or vet grade. Sust is good
