I just started using serostim after about a month of Nutropin. My question is does it sting/burn anyone else when injecting? Because the Nutropin did not but the serostim w/sterile water does. I got it from a pretty reliable source, with prescription stickers on it and all. I checked the lot #'s on Serono's statement on fakes and they did not match any of mine. I did not think it was supposed to sting like that. Any insight is appreciated.
