Im not a biologist but I'm B&C for many years now.
All I know is that with enanthate I get random gyno flare up , my libido is worse on enanthate and in general I don't feel that good as I do on cypionate.
It wasn't always like that first years enanthate worked good I suppose but after a while all this problems appeared.
I was trying to find the reason a changed ai dosing , my ai from arimidex to aromasin I tried more frequent injections but nothing.
Then I changed to sustanon and things was more unstable.
I thought about cypionate but I thought bullshit isn't gonna make a difference it's the same as enanthate, I thought that I was burned out due to steroid abuse etc but finally I tried cypionate and all those problems was solved surprisingly they solved pretty fast too!!
All this on TRT settings not on a blast I had staple variables. Maybe about my body chemistry idk but cypionate works greatly for me and I won't go Back to enanthate.
I know those are not scientific proofs but if I feel better on cypionate then I take it.
