I dont understand why my Test is wearing off all the time

[GettinBigAintEZ]

I got some Test E from a trusted source of one brand & two vials, it hits me good after 3 weeks, gain 15 lbs in 4 and a half weeks. Then wears off. I am on my second vial by then and figure the second is a fake. So I start over and use a different brand, a really QUALITY(*wink*) Mexican Veternarian brand. It hits me after 2 weeks because I front loaded and i gain another 2-3 lbs and im back in the ball game, but by the 5th week its worn off too.

Everything changes a few weeks in, libido dies, acne wears off and voice isnt as deep along with energy loss.

I honestly dont understand this and its devestating me. I thought maybe second time around it was because of the 100 degree weather i was storing it in but ive been told heat doesnt affect my test E

I would be DEEPLY indebted to anyone who can get to the bottom of this. I dont understand this at all. I have researched this so thoroughly that I know more about steroids than I do about what im studying at university.

Steroids work for like 2 weeks and then die. TWICE
