most melanotan/melanotan2 avialable over the internet is made in china. re packed or re labled and sold on.
there is some melanotan2 available which is made in the usa, which imo is alot better, after using both types, from several different suppliers.
chinese manufactured hormones/pepetides/drugs, are at best a gamble. as most are shipped unlabled, and with no form of lab report. they are however 90% of the time alot cheaper than those manufactured in the more developed countries. buying from these sources is sometimes a risky business though, and i would advise anyone who does venture down this route, to use a supplier someone who you know has already used with no problems.
i myself have been using mt2 for a very long time now, and have reported no long term use side effects as of yet. almost everyone will expieriance the nausia/headaches/and errections to some degree. but it all depends on the user. i have never experianced flushing of the face/hyperpigmentation/freckles/moles/white patches/dizzyness/itching or lethargy. but as stated in partyboys article, these side affects are widley reported.
lots of info available on the melanotan formums
