Way less sides with test e than cyp? odd?

I was running test cyp which is all I have ever used mostly because it has always yield good gains...the only problem I have ever had with it is that I bloat like crazy and am very prone to gyno so I use letro at 1.25mg every mon and fri which works well for me! Well I ran out of cyp and all my guy had was eth...didnt think anything of it so I grabed enth thinking it would be the same but It seems much milder when it come to sides atleast on my body???? I have not taken any letro in a week due to the fact that I just have not felt bloated or gyno coming on? same dose 750mg.

Anyone have the same experience?

p.s I know letro is strong so dont post telling me somthing I already know...a-dex didnt do shit for me even at 1mg a day so that is why I use letro.

Are they both HG?
I'm thinking that at least one is just dosed incorrectly.
