This is an interesting protocol. I have not seen this one before. I’ve seen things that are similar but at higher doses like 2-3iu insulin. No I don't think you will have a problem with 1iu especially if you are eating food around that time. If you were taking more I might be concerned. As for my thoughts on the program, I think that breaking several iu of gh up into 1iu shots is over kill. I do there there is going to be benefit to splitting a dose for fat loss but I wouldn't do more than a couple shots a day of gh if Im only taking 5iu total. Really, thats not what the top level guys are doing, meaning it isn’t necessary.
