Nice, I have not used this brand of IGF but it looks very promising, since it comes from the same company as Hyge's. Most of the IGF around now days is generic and various companies are selling different quality product, so this is probably one of the best choices for someone that wants to make sure they are getting REAL IGF. Assuming that you are going to split these vials up into at least 2 days, I would opt to use acetic acid. If you were to use bac water, it would break down faster, and just me personally, I would want to make 100% sure that I got the full punch out of each shot.
