Filter into a vial that complies with FDA particulate standards,

Considering how cheap relatively powerful microscopes are, it would a fairly cheap endeavor to filter a few vials from the major providers on MESO and optically observe the oils as well as anything filtered out, no? Is this something worthwhile to do or am I just missing the boat. @Ghoul @readalot

The fact that the photo you posted is only 60X kind of blows my mind, I could easily gather the materials to do that and then some.

Both brands that are sold at medlabsupply (ultra spec and alk) meet the fda code usp788 for particulate matter.. in case anyone was wondering..

This is so cool. Did they use QSC gear? Cause I can't figure out why it's in the thread.

Ultimate Warrior the goat BTW

I dunno....maaaybe we could ask them.

My bad for derailing this well-composed, organized thought process that is QSC.

I'm a little bitch. I'll try hard not to insert pointless comments in here going forward (or will I?).

 

[Dirthand]

While people are on the subject t I had some PTFE syring filters that I have use the Before before but the other day I tried to use some because my regukar brand was out.. they turned the gear I was using very cloudy.. I stopped immediately and just filtered the gear with a bottle top into a media bottle.. crystal clear.. then I refiktered unto sterile vials when the other filters came in. The bad ones were brand
Biomed
I normally use brand
Pekybio
Just thought id throw that info out there for you guys.. both I get from Amazon
I have never used the cell treatment brand but I beleive they are suppose to be a good brand

There are multiple people complaining about your lab. Is it my fault for posting in multiple threads (multiple people complaining)

Post in thread 'Fake HCG from QSC?'

Dec 31, 2024

I recently got 3,500IU HCG vials from QSC that failed the pregnancy test. I first put about 350IU on one diluted with water, then after that I did over 1,000IU on a new test with less water for a higher concentration. Both returned negative.

Am I doing something wrong or should I conclude QSC gave me fake HCG?

Wondering was there ever any conclusion to this thread like did you ever get your QSC HCG tested from Janoshik?

I'm an old time body builder now on TRT for over 20yrs and been literally using HCG for close to 40yrs. I recently grabbed some of that QSC HCG and I can tell...

Yea those aren't sterile. Sterile ones are individually boxed. I use some on Amazon but they're green and individually packaged

Cant a person just sterilize them?

 

[Ghoul]

FYI, I don’t think those are sterile.

Sterile filters are always individually packaged.

This is another decent brand, and you should pick yourself up some 13mm .22um PES filters for your peptides. Not just for particulates, but to reduce the number of aggregates to prevent immunogenicity and minimize the risk of, god forbid, hitting the "peptide horror lottery" of a self replicating misfolded protein from lodging in your brain and saddling your relatives with a drooling version of yourself with a destroyed mind.

I have read someone say that you can run a little BA through a filter and sterilize them... but i have no idea if that would work. However why.. i mean i try and be frugal myself but we are talking about one of the most important factors tors of gear...(sterility) so spare no expense in that department is my opinion..

 

[mikeh1998]

FYI, I don’t think those are sterile.

Seriously asking, does it truly matter if the syringe filter itself is sterile?

On one end of the filter you connect it to the syringe tip containing non-sterile fluid.

On the other end you have a sterile needle poking into the vial's rubber stopper.

So long as the fluid goes through the filter and into the needle wouldn't it be guaranteed that everything flowing in the vial is sterile?

I have never used a syringe filter so IDK.

Thanks, I actually have the pekybio filters for the primo. Don’t remember what brand I got for the HGH, but they are sterile. Forgot why I decided not to get cobetter, but might get some next go around.
