Sigma Audley Inc. - Your source for peptides, ancillaries, AAS, and more!

If you transfer vials, you should refilter.
You can get one of these seals (Tho I've not tried)

I've been waiting for these to come in stock for months now, no luck. Couldn't find them anywhere else, either.

Edit: looks like they're available in a few places now, but in rolls of 1000.
 
No, I'm talking about domestic oil from a very trusted source who over fills his vials so the stoppers are in contact with the oil, and in turn benzyl benzoate, which is a bad idea for long term storage. I typically don't mess with CN oils, personally
Wiser man than I. I couldn't resist the cheap prices. But there in the long term stash and I'll use the domestic stuff while I can.

Now you have me wanting to make sure I don't have any over filled. Thanks for the heads up.

The prices are definitely difficult to pass up. I did get about 30 test E vials from a Chinese supplier, but those are backups to my backups lol. As for the over filled vials, I've only found one of the four domestic sources I've bought from to have this "issue". The rest have plenty of clearance. I've purchased a bunch of vials with PTFE stoppers, which are highly chemically resistant, and plan to transfer everything over to those. The "how" is what I'm trying to figure out now. Trying to do everything possible to make these oils last as long as is possible. MCT oil (fully saturated means much lower oxidation risk), PTFE stoppers, filled as much as possible without stopper contact (less air=less oxidation), stored in a cool place with minimal temperature fluctuations and zero light.

Sounds like a good move. I'd hate down the road to find out the stash I have needs to be tossed out for some reason.
 
Received my HGH order - 24iu green tops from the June promo. Today I’m finishing my Lobster HGH, and tomorrow I’ll start the SSA batch. I’m honestly curious to see how clean it is, since a lot of people say some weird stuff floats around in it after mixing with bac water.
Please update once you know anything- good or bad. I have had my eye on this for a while
 
So transferring oils from one vial to another, assuming both are sealed and sterile, and a sterile process is used, should not affect long term storage shelf life? My concern is the same as the post you were replying to here, that by piercing the stopper, it somehow starts some countdown timer. I imagine this belief assumes sterility is compromised by this by either the introduction of bacteria or by a compromised stopper seal? I plan to use a thinner gauge needle to insure that the stopper reseals itself fully, so instead of an 18g maybe a 23g. Would a filter be necessary, or only needed if there is some assumed contaminant already present?

The idea is that pharma is perfectly, 100% sterile after terminal sterilization. Any compromise of the vial could introduce bacteria that could, over time multiply to the point of causing an infection. They don't want a vial pierced and reused months later.

Sterile filtration isn't 100% effective. As a practical matter what really protects against a vial becoming overrun with bacteria is the bacteriostatic environment created by benzyl alcohol. Just use proper aseptic technique. Sterilize the stopper, use a sterile syringe, and the amount of bacteria you'd introduce into a new sterile vial is inconsequential and not going to overcome the bacteriostatic environment, A good quality stopper fully heals, but to be extra certain, there's a sterile vial sealing sticker you can use to ensure the stopper is fully sealed.

Edit: I see you found the sticker.

I have heard similar comments regarding chinese oils in general. Some people claim there may be contaminants and the cheap vials they use can be problematic. I did not want to filter and buy new vials if at all possible, but the oil is cheap enough to make it worth it I guess. I just wonder how filtering affects the shelf life. I haven't filtered oil in the past, but I know once the vial is pinned, the shelf life decreases
Oil is filtered into sterile vials dude....

That's part of the sterilization process.

I'm currently trying to source those adhesive vial stopper seals in a quantity less than 1000 pieces as I don't feel like spending nearly $200 on them, but I'm OCD enough to order them if that's all I end up being able to find. I like to stack as many controllable variables in my favor as I possibly can.

If those Chinese oils have EO (which is likely the case), it is likely they will not last as long as the other oils you have. EO has a much shorter shelf life, same for GSO.

How is this done for pharmaceutical peps that can't handle heat? Gamma radiation?
 
I know, which is why I dont understand why chinese oil would not be filtered to the same standards as domestic sources

Money talks.
See the difference in prices.
That being said, even large India pharma like Sun Pharma may not be any better than China lol

Never used this place but low quantities here:

By this logic Chinese UGL is even higher quality than pharma.

After all, unlike regulated, routinely inspected pharma companies staffed by professionals and subject to being held legally responsible when something goes wrong, Chinese UGL has never once failed an inspection, been subject to a recall, or sued by someone hurt by their product....

Dont filter it then lol.

They won't be cutting corners. It will be fine, why would they ever do that?
I understand what you're saying, and the same with cheap vials. I'd rather be safe than sorry and the oil is cheap enough that it is still worth it. Someone else brought up EO, which I read about in the homebrew threads but still dont know what it is. I haven't ever tried chinese oils and want to know, it makes sense that they would cut corners. It also has me thinking because the raw shortage that domestic sources are just buying chinese oil, filtering it and then reselling it in new vials

I definitely would not say that.
Some of these pharmaceutical companies are so large that they probably can afford not to care about alot of these regulations. A fine is just a slap on the wrist. In the article i linked, they've had lapses going back 20 years and are still occurring. Not all pharma products are equal.

I'm just saying to not blindly put faith just because it is "pharma quality". Also one of the reasons i switched alot of my medications to US pharma (but yet it still comes from India lol). I'm hoping the products go through stricter inspections, but who knows?
