Is it normal for a rat to feel like its twenty bucks better about a half hour after its dose of igf? My rat was given its dose, started doing his exercises and was feeling like it was just another day, when like third exercise, the rat seemed to just wake up, and seemed just ready for it. then, the second dose of the experiment, same thing. I would brush off the first, bit the second time was even more seemingly clear. have any of you researchers out there experienced this?
