Filtering finished oils

One question about filtering finished oil

As many guys suggest me to filter Chinese steroid oil (thanks for advice)
I'm planning to filter my wwb finished oils

when I filter it with PDFE filter syringe
Could it lower the steroid content dosage in my oil ???

Wow, so even major pharmaceuticals?

Does anyone in the US make raws/test, etc?

Maybe all of this will cultivate domestic production.

Pfizer makes API's in Michigan. Not sure if thats where compounding pharmacy get there test or not. It looks like they make raws of TNE, Cyp, Prop, U, and interestingly Tren Ace.

So i have been filtering a few vials from UGL, i noticed that the residue from the UGLs spread out in a different way than the sterile vials i am filtering the test E into. I am using Ks Tek from amazon so they may be trash tbh.

Vial on left is unfiltered and right is filtered. You can tell see what i mean with the residue/drops left behind. I am just curious if some of the glass vials are coated with something?

Looks like I can get a 100ml Ks-Tek sterile vial in a couple days. While it won't hold all 140ml for each batch it will have to do. I can pull evenly (~7ml) out of the 14 vials to get as close to 100ml as possible and draw from there or I can just do 10 vials. Any suggestions on what everyone would like to see?

@Primal_Pharma I will follow up when I have everything transferred and ready to send out. I will document my process too.

Wouldn't use.


Are they clean and...

KS tek was not recommended. Above is a linked post discussing it. Not sure if it’s causing your issue though.

These are the 2 vials that are recommended for use on this board.

UPS rated ALK vials
FluroTec coated stoppers
Better than the below, but expired.

20mm, 10ml and 30ml Non-Sterile, Empty, Clear Glass Vials with FluroTec™ barrier film, EXPIRED

Non-sterile 20mm, 10ml and 30ml FluroTec™vials are expired and are no longer considered sterile. These are for use with procedures that do not require the vial to be sterile.

UPS Rated UltraSpec vials
PTFE stoppers

Ultra Spec 10ML Clear Sealed Sterile Glass Vials, Qty 1

Ultra Spec Sterile Clear Sealed Glass Vials - 10ML (20mm Neck) made of SCHOTT FIOLAX® glass tubing. In order to receive vials in sealed shrink wrap boxes, please order in multiples of 25.

I haven't seen any comparison so Im posting mine.

Review for the 30ml vials
ALK vials does seem to be of better quality.
Its a tiny bit wider and little longer. It can probably hold an extra 1ml or more vs the UltraSpec vials.

The FluroTec stoppers are significantly tougher than the PTFE ones. It is significantly harder to pierce which is making me think twice to use with insulin syringes.

Other vials
MedLabSupply also sells ALK sterile vials, however these are neither FluroTec or PTFE coated and so i do not recommend.

KS-TEK was one of the first vials i used, the quality of both the stoppers and glass are poor, i also no longer recommend them.

The ALK vials day they are not longer sterile. Do you think they will need to be sterilized or are they still good to go? I just purchased 25 ALK new vials, but that cost over $100

Posting this in the homebrew forum because it feels more relevant to homebrewing than peptides, given that most people aren't transferring peptides to 10 mL vials.

I recently reconstituted some HGH from the same kit I've been using for a month, but this time I tried to be more efficient and instead of transferring to individually wrapped, sterile 3mL cartridges, I used these "sterile" 10mL vials: Amazon.com

After transferring, the HGH appears to have come out of solution and just rests at the bottom of the vial. No improvement from letting it sit overnight, swirling / shaking it, or even adding more BAC water to bring the concentration down from 13.33 IU / mL to 6.67 IU / mL. Hospira BAC water was used.

I just tested it again and reconstituted more vials from the same batch with the same BAC water, and they're perfectly clear. In the picture below, the two vials on the left are the newly reconsituted ones, the third vial is the 6.67 IU / mL vial that has been shaken to show the dispersed cloudiness, and the one on the right is a 13.33 IU / mL vial that has been sitting undisturbed for a while, where you can see all of the powder resting at the bottom.

Lesson learned: don't buy medical equipment on amazon.

The first link?
Because they are expired, they can no longer claim to be sterile.
They are good to go.

Non-expired ones will cost like 4-5x more.

If the gear is crashed, absolutely.

If a solution (visible clear liquid), absolutely not.

Make sure the gear is dissolved before filtering.
