There way too many fake IGF-1 peptides on the market these days. In the best of the cases you will get a bunk product that will give no results. In the worst of the cases, you will get IGF laced with some PH's that will cause a lot of side effects. The best alternative would be MK-677 nutrobal - it will give a very good boost in IGF1 levels.
As for the bromo, it is oldschool, and was used back in the days when no alternatives were available. However, now that Caber is there, I don't see reasons good enough to use bromo.
