nope, none lol, i dont fuck with anything else, i stick to Lr3 IGF-1 , but i have used almost every peptide imaginable as of a few years back, and nothing compares to igf-1 , though there are some new things out or more readily available anyhow, that i havent tried and might like to, but over all, IGF, and Propionate is all i need for the most part
