If BA is an issue, cutting w b12 didn't help much, had to cut w sterile oil/cottonseed oil and bake it. this reminds me, a while back, i made a mistake of doing T400 by Denkall, that **** was probably one of the most painful shots ever. Cutting with Test is also an option, however, personally i wouldnt cut w Prop, Sust or Suspension, as they tend to sting.
I agree w crazyfool, when i was overseas, i did the Zambons Winny's, 2 shots IM then chug one down orally, just because after a few weeks of ED shots you start to feel like a pin cushion, guess i did it for convenience and comfort factor.
Gd luck bro!
