The shot you're talking about is progesterone, sold under the trade name "Regumate". I agree with the more training suggestion for a few reasons. The biggest being that it is very expensive and others being that I just don't think that you should play around with hormones, even though the drug is completely safe. Hormones have lots and lots of functions in the body and I just don't like the idea of using them as a substitute for training.
If she really is that night and day, let me ask you a couple of questions- has she always been like this or is it a change? Would you say she acts like a "stallion" or just a cranky mare. There could be more at play here- namely a hormone secreting tumor on the ovary (don't worry, almost always benign) which causes changes in mares. The bottom line is that hormone injections are either a short cut for good training or masking a health condition that needs to be addressed. If she has always been this way, then maybe try some suppliments like Mare Magic, which we have had good success with. Everyone is entitled to their opinion, I just feel that throwing drugs at behavior problems isn't always the best solution, though it DOES work.
