I have been taking yellow top hgh for 1 week at 2iu a day 5 on/2 off. on the second week I got my hands on some green tops and upped the dose to 3 iu. ed. on the second day, a red welt appeared the size of a silver dollar at the first injection site. a day later, another welt showed up on the second site. they dont itch (as I read in other posts) but the are a little sore. This morning I switched back to the yellow tops so Ill see tomorrow if theres a welt there too. Could it be from the different brand? or from upping the dose? for anyone that has have these, will it go away? will they stop? any and all info would be greatly appericiated.
