So im on my 4th cycle now, and i loaded up 2 cc`s of test into my syringe, picked a spot on my quad where i normally inject, pinned, then aspirated. I saw no blood and continued on and put the whole 2 CCs in. Now from this UGL brand of Test i normally get bad PIP, but this time i didn't. Immediately after injecting the full 2 cc`s i felt like my lungs were filling with a gallon of water, and i had a chest pain similar to a heart attack, also i was getting dizzy etc. Its been 12 hours since the inject, still no soreness on the site of injection. All the symptoms went away besides when i take a really deep breath i have a slight pain and the urge to cough. Other than that im doing fine and just got back from the gym actually. Any idea why im having that problem when i take a deep breath? Im pretty sure i injected into a vein, i used a 25g 1 1/2in needle.
