It's a shame. Every peptide supplier has seemingly had this issue at one time, fixed it, and didn't have it happen again.
This was brought up here months ago when a customer asked what to do with his rHGH vial lacking vacuum, and after suggesting filtering it to remove the potential bacterial contamination and aggregates that oxygen exposure can cause, an army of shills. one in particular, started a war insisting that a) it wasn't happening and b) if it did happen, oxygen exposure didn't matter (complete bullshit).
Lobster might have fixed this issue once and for all had it not been for the encouragement of the ass kissers reflexively defending their preferred (cheapest at the time) vendor, instead of acknowledging lack of vacuum was an issue, taking care of the customer, fixing the process, and moving on.
So here we are again. Another in the long line of customers finding they have vials without vacuum.
Only this time, unlike the previous customers who were bullied into silence, a replacement is offered without hesitation.
Why replace it if lack of vacuum isn't a quality problem? Because it is. It always has been. But the shills have largely moved on to the new low price leader, and so finally it's being taken seriously, 6 months too late.
