From my limited knowledge the pens have a longer shelf life and can stand temperature changes better than vials. So it eliminates the worry of the GH being ruined if shipped to hotter states. Even though the powder is not reconstituted it CAN be damaged by drastic changes in temperatures. Example: you get HgH from an international source, which even these domestic guys do, before it gets shipped to you maybe it’s from china or Taiwan or Mexico and it’s hot AF there and you’re in Michigan in the winter time the GH could be damaged lose potency or whatever.

The pens don’t have that issue, why? I have no idea but that’s what my research found. Pens also have the BAC water right in there so you just push it and bam it’s reconstituted. Then you can treat the pen like a regular vial and draw out of the tiny little rubber hole and pre-fill slin pins if you choose or just keep drawing out of the pen.

I live in the dirty south where I was worried about this problem so I did some research.
