I did a small order with matrix for the TC Premium. All I have to say is OMG, dealing with him compared to the Chinese vendors in this board was refreshing. I've never delt with Stan or any other domestic here.
The package arrived in a small USPS flate rate box. Vials were vacuumed packed, wrapped with paper and put in the box.
Vials were shipped the same day as the payment was made and arrived in 2 days.
Since this is for trt, I haven't pinned it yet but I really hope this premium (enhanced testing) line catches on!
Those of us who made it out of our parents basement will happily pay the small additional cost for the additional piece of mind.
