ITS YOUR GEAR DUDE...
I have never used synovex, but I have used fina. It sounds to me like you tried to make your gear stonger than the kit was designed for (fitting 304mg in 2cc). What I read on this matter is you are getting too much BA in one area. You are actually damaging your muscle fibers by doing this. if you really want to do the test, either get yourself a new synovex kit and convert it to the correct mg/ml dosage, or get some new gear all together.
I would give your legs time to recover before I stated this new cycle too. but that is just my opinion. I've only done 1 cycle myself. So take it for what its worth.
Also, I wanted to add that test with no ester is supposed to be somewhat painful anyway (from what I hear).
Did I read in this thread you are working out after you inject? THAT IS NOT A GOOD THING TO DO. I did mine before bed time. be gentle with the muscle that you just put 2cc of oil in. it needs time to absorb that stuff.
