in my opinion eq is eq is eq..
go with the 50mg Eq, these days the 100mg and 200mg Eq's on a mg per mg basis are more expensive than the 50mg versions, and since you wont need much then the volume of injection as well as frequency wont be that high so a 200mg eq has no advantage over a 50mg eq for you, unless the price is the same on a mg per mg basis...
get the cheapest per mg you can find...nowadays you will find 100 people who will tell you 100 different favorite brands, so as to what brand, that can be argued over and over again.
BTW
eq made me VERY hungry and also made a female i know VERY hungry as well. but the pumps are crazy. how many mg a week you inted to do? 75-100mg or so??
