I feel very strange for a day or so following injection into the thigh it seems to hit me too fast or something even when i take arimidex i get very spaced out. Then after a couple of days i feel great even with no anti estro. tied in to fatty area and it was better; is this ok.
Yes it's no problem. I've been injecting there for several years.
Read the protocol for injections sticky!
You could have injected into a vein. That can also create a tickling sensation in the lungs, making you cough and other sensations.
Have you considered injecting more frequently?
Or maybe, you are hitting the trough from your previous injection and don't feel good until the next injection starts kicking in...
