yep, i've used the 900 iu pen and there's always a little left.
thanks that makes me feel better.
If you dialed 150 and you have 300, you should still see some liquid because you only have used less than 1/2. From what I have been told, even though you have a vial of 300IU, they usually put more in there. I would guess that it actually has 325-350 IU in there. The bad thing is that you do not know how much extra they put in there. :)
I don't have a vial that I put in the pen. The pen is already pre-loaded. I just dial 150 on a 300iu pen and then I pushed the button and it did the clicking but I still see clear liquid (not at the end of the needle) but in the bottom of the pen.
I was waiting for someone to post to help you. I am not sure what you are talking about. I also use a pen, but with follistim. They are supposed to be the same thing. I leave the vial in my pen, have not seen much of it since I pierced it the first time. Are you asking if you should see clear liquid at the tip of the needle? If so, I don't ever see any liquid. I just trust that the pen administered the correct amount that I dialed in. If it did not register correctly, I would imagine you would not be able to push the button in and it would remain at the same amount that you requested.
