Since I know Primal values the improvement process, here you go. Pharma vs Primal
Pharma vial cap and crimp comparison. Ran an alcohol wipe over the top of both vials. Wiping the Primal cap ain't much fun. Plus the aluminum shell is not tightened properly. End of the world? No.
You can see how the aluminum bridges on a legit cap tear away leaving no snag points. Compare to a cheap China cap that doesnt tear away properly leaving raised bridges that trap fibers (from alcohol wipe) on the top of the vial. Also notice the crimp quality on both vial caps.

Yep that 13 ct/unit West Pharma vial cap makes a difference. Why create any issue that interferes with user wiping the tops of their vials before injection?
