I did a lot of research and found that most people reconstitute their igf with aa instead of bac water. The pain that comes with that injection is unbelievable. I do it bilaterally after lifting im. I've also tried sub q once and had serious inflammation for a month. My question is...is there anyone with any knowledge on if using acetic acid is better and the pain is normal or is bac water ok? Thanks for your time fellas.
