The vial arrived sealed with the batch printed on it. I looked it up in the registry before opening it and the PDF was right there.
The 10 mg came as a compact cake at the bottom, not loose powder. Reconstituted clean with the bacteriostatic water.
Third order already. Last time I got five at once and it came out way cheaper, so that's how I'm ordering from now on.
I emailed asking for my batch's certificate and they sent the PDF the same day. Wasn't expecting an answer that fast.
