no its not faked alot because its a lower costing steroid meant more for animals than human still good stuff. it is ruffer like the pains your getting now adays stuff can be faked down to the T. But in your case its more unlikely to be faked not saying they dont, still fa*gots out there who cant get a job and rather rip people off. But if the area turns real red and starts forming like a pimple and hurts so bad that you can't walk than go see the doc tell him the truth and he'll drain it for you, if you can hobble, your okay, cant walk bad like pirate said what gauge is it try another spot injection not on the glutes to see if you get the same result (pain wise),make sure you use different length and gauge depending on site you inject at and that'll definitely narrow down if you got abcess or just pain from oil.
