no clue bro, but i doubt it was legit igf-1. people were claiming they felt gains off follistatin and that shit was god knows what in a bottle but certainly not follistatin. i really have no clue about the gains people get from running bunk peptides, i just contribute it to the other gear people run and then the placebo effect from thinking the peptides are actually working and then people consequently training harder.
i don't know about the customs of other countries, sorry. all i know is australia is the absolute worst when it comes to customs and as a result it inflates the hell out of prices in australia.
also, like i said before, i wouldn't even run it even if it was legit. i think it's a waste of money, honestly. systemic igf-1 levels are more associated with physical maturation of bone and body structure, and it actually inhibits local igf-1 production at the cellular level which is one of the primary causes of muscle fiber hypertrophy and hyperplasia. i wouldn't use it, shit, i am worried enough about my big ass nose growing from just using hgh and insulin together i don't want my igf-1 levels going higher.
