Vials with poor vacuum
-
When I first started ordering peptides directly from China, they all seem to have strong vacuum. I just ordered five kits of wolverine and one out of every three seem to have weak vacuum or no vacuum. Is this affecting the product, is this something I should demand a refund for?

Action depends on your personal risk assessment.
My opinion is…Low vacuum proceed with caution and be sure to filter. No vacuum is a red flag
and do not use. If you bought dark grey good luck requesting a refund without paid testing backing up your request. The worst they can do is say no and not sell to you again. -

@RVZO I've had that experience with Wolverine too recently from multiple US resellers with full breadth COAs from from Vanguard.
I observed how the product reconstituted and later if it had any issues during research but it stayed clear all throughout and without research issues so I didn't bother with refund.

Honestly, I've been through a lot of vials and maybe experienced a vial with no vacuum like 3 times. At that time, I just toss it and request a refund / consider it as a lost. Rather be safe than sorry is how I see it.

@PeppersUnboxed I reached out to the vendor after this discussion. They said their vials can have both positive and negative pressure and it's not a sign of quality or lack of it. FWIW it's from a reputed vendor and with Vanguard COAs, but I know there are people on this forum who strongly feel against trusting any vendor or any COA except their own.
UPDATE: the vendor offered to replace my remaining vials on their own with their latest batch vials. The vendor is of course none other than Peptidology!
Some stateside lyophilizers use nitrogen for sealing than vacuum and those vials don't have vacuum. I used a few like those. So I don't feel strongly about tossing them.
I had no vacuum pull experience from 2 different vendors' Wolverine blend.
