I would like to start by saying I HATE THAT CRAP.. ok now I´ll answer.
Yes I was fairly sick for about 2 weeks, flu like stuff, little fever, sweating at night a bit, ohh and a huge ass lump in my quad that made it nearly impossible to walk.....
Mix with EQ or Deca and shoot it in your glute. If you shoot it up in any other part of your body, you will be very sorry.
I was on that horrid shit for about a month and the gains were not enough to make it worth while. I made ok gains but with my normal sust I do better plus it doesn´t cause 1/10th of the pain I had when I was shooting that test400 garbage in my leg.
Use what you have of it and never buy it again is my suggestion. It just flat out is not worth it and I highly doubt there is 400 worth of test in each shot.
