Just received my sample* vial from MD. I've always tried to avoid Fuerza because I haven't heard good things about them, but now I'll give them a go.
This vial will be Mass Spec'ed as soon as my buddy is back to his position. Meanwhile (and mainly because I have some faith in MD), I'll start pinning it in addition to my ongoing Test E cycle to see how I feel on it.

* On MD's end, this was just a normal order of 1 vial. So this was not sent to me by MD for testing purposes.
