How fucking entitled are you that you think you shouldn't have to wade through 20 pages of dumb shit.

Now tell me how you feel about almonds?

4-6 weeks right now. After the holidays I would say 3-4 weeks.

I think concern may be premature, but Biden did say he intended to implement the tougher de minimus rules before the end of the year. Hopefully this isn't that. Please let us know if you see movement.

Think he remembers saying that? Lol

No, Proteins bind to PVDF so you'd lose peptide., PES has very low protein binding properties.

13mm has a holdup volume under .02ml, or 2 units on an insulin syringe vs .08ml for 25mm. 13mm can filter around 10ml, while 25mm is good for up to 100ml.

Makes sense, i always run PVDF for AAS oils.


Do you know if PVDF hydrophobic vs hydrophilic matters for filtering AAS oils. I've seen both kinds.

I was on track for 2-3 week delivery International to USA until this custom's bullshit happened.

That's me who is replying now on whatsapp.

My assistants are asleep. It's late night now.

Well fuck. That totally ruins my fantasy about the rep typing in thigh highs and a lace bra.

I mean... Being a member since 2016 and still haven't figured out that this forum has a homebrew section.

That does not necessarily ruin your fantasy.

Either will work, but hydrophobic allows for faster filtration.

PTFE or NYLON is best for AAS... PVDF will work but marginal with higher BB content. Best to use ptfe. There is a few charts floating around for membrane compatibility.. somewhere...

Thread 'Filter membrane compatability chart'

I found this very helpful

Take away-

Nylon and PTFE are compatible with ba/bb


Pvdf states "No Compatibility Data Currently Available" for BB

Well it’s on hold for now. This elevator music sucks

What's the difference between PES and PVDF for filtration? They both work?

Yes, make sure the PVDF is hydrophilic for peptides.

Can you reply to my order? Going on 3 days now.

@Ghoul do your AI image magic and make his fantasy true.

I have 4 different shipments hung up at different stages. At this point I’m thinking January for most of them.

I just messaged on WhatsApp, order placed and payment sent/confirmed all within 10 minutes.

Nice. I'm still waiting for a response since Sunday

I think your WhatsApp has to be messed up. I really don’t know. I’ve never waited more than 10 hours on a response back from WhatsApp.

For emails, all the tuesday emails during China working hours got a reply, we only have emails left from about 12 hours or so, so pratically no one gets a slower reply than 24 hours using sigma@sigma email.

Whatsapp we have a larger delay, I have replied to all whatsapps sent earlier than 48 hours ago. I also found some unreplied whatsapps due to some chat history deleted, only few ones and I took care of them. I also sent plenty of tracking numbers for the ones who request them.

BUT you need to know that if you send again a new whatsapp message actually it gets you on top in whatsapp, like if you sent a new message, so you are considered a 18th dec order.

And please stick to the ordering form, avoid useless chat to optimize the processing time.
