I'm 100% behind cutting out the middle man. However, I do not believe there currently is a safe and reliable way to do so. The primary function the middle man serves is to hold the factory (or factory reseller) accountable. Good middlemen/sources test each batch, and with popular sources, many customers do their own independent bloodwork and testing. The factory/reseller knows this and is therefore far less likely to send our middleman/source bunk shit.
When you place an order directly from a factory rep/reseller (lets be honest, they're 99% resellers), what means do you have to hold them accountable? Are you going to get each order tested? That defeats the cost-savings (and then some). Perhaps you get bloodwork covered by insurance and that shows that it's bunk. How will you remedy the situation? Give the reseller a bad review on alibaba? Send them a harshly-worded email? They most likely won't give a shit.
Or lets say you get bloodwork done after your first order and it looks great! Awesome! How can you know the next order won't be mannitol?
I'm in no way trying to discourage anyone from finding a reliable source direct in China who sells for a reasonable price, but for right now, I'm willing to pay the up-charge to dramatically increase my chances of receiving legit GH.
