Endotoxin Warning

Same, I just use it for finding tests, or at least trying to.

Same

May I ask - why do you think that is? The way the site is organized on TG? Or is search not good enough? Not enough vendors? People not helpful?

I thought that they were very proactive in managing vendors. Seems like they mediate disagreements with vendors and kick them out if they don't behave. Don't know how true or useful that is.

Just curious.

Well, they don't sell anything, so they don't have any vendors. They might recommend them, but I looked once, and only saw one I used, and I use a bunch of good ones. Likely a good place to learn about stuff and crypto. Test results only like @sheilarae74 confirmed.

I’m fairly certain FSD is their backup brand

Perhaps that's why their T30 has high endo as well? Obviously not as bad as 1360/vial.. but still.

 

[Wellwell]

Are we still seeing high endo for t30 being sold from other vendors? Looks like I may need to wait on my T30 purchase.

Not recently that I have seen. Possibly but has not been reported?

This is why I purchase from US peptide companies that do 3rd party sterility/purity testing and include testing for endotoxins and metals. I'm willing to pay more for peace of mind.

I don't trust the 'US companies'. They don't manufacture it, they buy the same grey market and then, hopefully, maybe, test. Or not -- their customers have no recourse.

Everything I get I test on my own. This way I know exactly what I have received and who tested it. I do not do sterility on lyophilized powder since it is pointless, but HPLC and, LC-MS, and Endo is on the list. Costs more, but, for me, I will have a peace of mind so long as the lab results I see are from a trusted source.

 

[zkprv]

Can a sample pass sterility testing, but fail endotoxin testing? Or vice versa?

Sterility testing on lyophilized powder is largely low-yield and often pointless --the powder is very low in live bacteria since the drying process removes water; some spores might survive, so while the risk is not zero it should be relatively low. Also, sterility testing takes about two weeks of incubation for both aerobic and anaerobic bacteria and is sample-specific. Endotoxins, being dead bacterial fragments, are a whole different story...

Thanks for sharing, and also for that risk calculator on your signature! Haven't seen that before and it is very helpful.

Can you clarify what you mean? I think you are saying that lyophilized powder will have little to no live bacteria. Does this mean it will always pass the sterility test? Is that test useless then?

What does that mean for the endotoxin test? You just said that's a "whole different story".

I was surprised when I first discovered "testing" centered around mass and purity in most discussions. Mass and purity should be the bare minimal IMO.
My understanding is M&P testing has only become common over the last year or 2 and yet even today vendors cheat the system by using forged or out of date M&P COA's and offer no guarantees on sterility or endo contents.

Nah, M&P has been the standard for a long time. What changed about 2 years ago was the expected M&P for refund. It was once as low as 95%, the community drove it to 99% for GLPS.

Thank you, hopefully the community can drive them to cover endos next.

Just to add that QST has the same possible batch and cap color which is lilac. Batch is QST R30 25Ja01 lilac cap. It's not unheard of that all the lilac caps come from the same source, as we've seen before. FSD COA attached.

Do not do a group buy. That involves trusting someone! group testing can be done in a way that you are never just bestowing trust.

I found a lot of helpful guides in stairway to gray

I did group TESTING before and that was fine but my current ( first and only ) GB has me swearing to never do it again. Too frickin' long of a wait. 🤨 Now I'll just have to be happy if it shows.
( and I used to think CN shipping was long! 🙄 )

I've been in several GBs and I'm always happy when it shows up 😀 I like the testing and the prices are usually pretty cheap, but I only use them to fill in gaps and add to existing inventory. I've waited as long as 4 months and as short as 3 weeks. You never know.

Yeah. I’m doing more research in that area now. And I’m not entirely sure. That GBs are bad. They just require a lot more trust the. Doing group testing.

I may have done things differently if I had one. Differently.

I may need to update my post to reflect that change in opinion.

FSD, TFC, QST... sounds like the dirty dozen crew living up to their name. /SMH

Andys and jeep too. That 536 or whatever isnt too bad if ur taking 10mg dose youre injecting a third of that. Im 100kg so theory is under 500 a pin is ok....or divide by 30 and thats the endos per mg.
