No lab reports exsist on their "Primo" but I'd sure like to see it. I only get my Primo from one guy that gets Scherring Primo 1ml vials from Turkey. I know they're legit b/c a lab test on it was recently posted.
Until there is a lab report verifying the legitimacy of Sydgroup's Primo I wouldn't touch it with a 10-ft pole. Look at BDL and RSOC as examples of that.
There is only ONE manufacturer of Primo I trust and that's Scherring. The only problem is Scherring discontinued its Primo a while back but there are legit Scherring Primo amps out there mainly in Turkey. It's very hard to find on the black market and it's not cheap.
