I have a few of the millipore sterocups 1000ml packed up.. i used a couple of them when I first started and I think they were the reason some of my gear come out cloudy, but i can say for certain. ... I figure i may use them for things with lower bb % like Test E and EQ. It is hard to find PTFE sterile bottle top filters... KS-TEK said they would nake some but it would be a coupke of months out.. that was about 2 months ago i never checked back with them. I've just been usung syringe filters and vialing everything up as I make it. I was doing bottletop filter and syringe filter but after I did some sterility testing both ways I found it to be unnecessary...
Alibaba 24x 250ml ptfe bottle top filter 75$ or 24x 500ml 95$ :)
 
I regret having to publicly criticize QSC, but I'm starting to feel deceived by their actions.

I ordered during the Black Friday promotion and paid promptly. However, communication issues arose as Tracy (WhatsApp) and Tracy (email) appeared to be different people. I had originally ordered through Tracy (email) but requested bank details from Tracy (WhatsApp).

There was complete silence from November 30th to December 14th. Between December 16-18th, I was informed that tracking would be available soon. I thanked them and inquired about the tracking on December 25th. On December 26th, I received a message stating that QSC was having issues with their bank account and I should check if my money had been returned, which it hadn't.

For 32 days, I've essentially been strung along, only to find out that my eagerly anticipated order won't be shipped. I'm now told to expect a refund in 2-4 weeks.

This experience has been frustrating and disappointing, especially given QSC's reputation in the industry. The lack of clear communication, extended periods of silence, and the eventual cancellation of the order without proper explanation have left me feeling misled and undervalued as a customer. I expected better from a company of QSC's caliber and hope they will address these issues to prevent similar situations in the future.
Something similar has been done to me. From when I made the payment until they verified the payment, not that the money had not arrived in their possession, 9 days passed. With Yura in 2 days it was enough to verify the payment. Both cases were transfers and from the same bank account. and then it took 10 days to send the drugs, etc.

Well then just use yura to get your supplies from.
 
That's what u was thinking. And if they say they are out.. persistently send another right away!

Exactly what I would do. This stuff's getting scarce. It could go out of stock before the first person gets a reply as to whether it's time to order or not.

I actually emailed a few days ago and they were willing to sell me a kit of the primo200. I backed out since I didn’t need a whole kit and 1-2 vials for $300 was a bit steep. Point being, if you place an order you’ll probably get it.
