Just wondering if anyone else has experienced this. I gave myself my first low dose Estradiol Valerate today in the vastus lateralus, and I noticed that as soon as the injection was finished and I pulled out, I felt a slight head rush that lasted less than a minute. Everything went as it was supposed to, aspiration, placement etc., so what I'm thinking is that it was one of two things: because it was my first one at my home I probably built up a bit of mental hype about the whole matter and it was just adreneline. Second, many many years ago in my using life I used meth constantly by way of syringe, so it may have just been that playing out of the mental scenario my brain was expecting. Once it was over I never felt anything again, so I dont believe that it could have been placed in between muscles. I had settled on the 23g x 1" and my legs are kind of skinny so there is no doubt all went welll. Just curious, thanks. Dani
