Look through the Source Review Section.
That should help to narrow it down.
There are reviews by alot of members....................... JP
P.S.
I would Disregard the Reviews from what I call the 1-Post Wonders.
Guys who come just to leave a review or 2, and then Never Heard from again.
So Pay Attention to their Post Count and their Join Date.
What did you bought from them? I have bought MK-677 from ProvenPeptides, they are unique, just send my 2 bottles of MK within 2 working days.
5 star for you and for ProvenPeptides team.
Maybe this is a total noob question, but I've been through there, and aren't all those reviews from like 1-2 years ago. I don't know if the shops reviewed there are still legit in 2017
