I shot my eq the other day for the second time, and I have had the same stinging sensation - even though it was mixed with equal parts Tren and Prop - as the first time. I know its not the Prop or Tren, because they are both homebrew and previously tested. Is this just a higher BA content talking? The stinging sensation is not just upon injection . . . it persists for hours afterward. I no longer feel it tonight (the next day). Just curious. BTW, my EQ is SL 250, if that sheds any light.
