Chris same thing happens to me, but I used to take mine PWO, and then eat my post workout meal. I had to eat a banana or drink fruit juice with the IGF and that solved it for me. As for your bs dropping at the start of your routine, I will assume you feel, shakey, and weak. You make take that as a sign of a bs prob, but I am wondering if its something else, or even a bp drop. Hmmm, I am a little stumped here. Truthfully, my advice is, if this is actually going to wreak havoc with your bs, and if its going to cause you worry, get anxiety and/or lose confidence in the product, than dont do it for a while. It wont make or break you one way or another. Also with all the compounds that you ran till the nationals, its still early for complete cleanout, and that every system is operating 100% full capacity on its own. I will think about this some more......
