Where can i buy melanotan???

This is easier then you think.
best and cheapest is to buy directly from the peptide factories in china, like GLS china.
You can also buy from a reseller on the net. But guess what, all the resellers buy their melanotan also from the peptide factories in china.
do a google search and you will find plenty of peptide factories in china.
aks for a high purity (at least 99.3%) and ask for the GMP production certificate..!
