This wasn't what I was referring to. I was referring to the large group testing..thanksWe know the stinging is not because of lower purity or lower sterility so not sure how much help are those tests in identifying the root cause. Unless someone from Amopure provides a definite answer, we are just guessing here.
Obvious not conclusive but I’m pretty sure I’ve seen users on this forum claim stinging from T10, T15, and T30 but haven’t seen anything solid on T60 or any R.Wanted to see if stinging / burning is limited to T10, T15, T30 and R10 or has anyone seen any reports, here or in other forums, about it also impacting the T60 batch from Amopure?
There’s two folks with late August purchase of R10 (my RS being one) in another thread both experiencing same sting.Obvious not conclusive but I’m pretty sure I’ve seen users on this forum claim stinging from T10, T15, and T30 but haven’t seen anything solid on T60 or any R.
Reta thread has similar reports on stinging.Obvious not conclusive but I’m pretty sure I’ve seen users on this forum claim stinging from T10, T15, and T30 but haven’t seen anything solid on T60 or any R.
Not sure why you are saying we know this is not because of lower sterility, since (as we have discussed to exhaustion in other forums) there really is no good test for sterility / contamination. I think someone else's comment implied a freshly mixed vial should be sterile / uncontaminated, but bac water does not kill existing bacteria, it only slows the growth.We know the stinging is not because of lower purity or lower sterility so not sure how much help are those tests in identifying the root cause.

You are correct that there is no great test for sterility as most people think. But the right way to frame it is that it's unlikely a sterility issue because that isn't how they manifest. The mere presence of bacteria doesn't present as burning, that comes from the body's antibody response.Not sure why you are saying we know this is not because of lower sterility, since (as we have discussed to exhaustion in other forums) there really is no good test for sterility / contamination.

This is why I think people are way too focused on sterility, and some are even spreading unfounded claims that Amo has sterility issues. A sterility problem would cause after-the-fact injection site infections, not instant burning. This issue is more likely an irritant leftover from the manufacturing process.You are correct that there is no great test for sterility as most people think.

I agree that if it was a sterility issue, there would be longer lasting symptoms and no one seems to be reporting that, although I don't agree it wouldn't also cause an immediate response as the body goes to work fighting off invaders.You are correct that there is no great test for sterility as most people think.

sterility testing is done on agar on min. 2 different mediums, and as someone who did grow 'shrooms I know that any contamination will be 100% visible on agar after 1 week+I seriously doubt the sterility testing being done right now will show anything either.
agree + the most possibly the filler issueI'll bet there's a residual from manufacture that is causing it.
I have a Labor Day sale batch of T30 sitting in my freezer right now. I don't need it at the moment so I'm playing a wait and see game for this group test that's happening and if there are any more reports of stinging. Like you said, nobody has complained about an injection site infection, which really should put the sterility concerns to reststerility testing is done on agar on min. 2 different mediums, and as someone who did grow 'shrooms I know that any contamination will be 100% visible on agar after 1 week+
but we know it is not sterility issue for sure, because if it is, there will be no stinging during the injection, but there will be injection site reaction later - swelling, redness and itchiness
agree + the most possibly the filler issue
+ ph I saw somewhere someone did already and it was OK
just lets hope the issue is resolved already, I would like to read some reviews about the new batch or the replacement batch
Hi, I'm new and have been asking around specifically about GCMS testing for residual solvents vs HPLC testing for purity, and so far I can't find any examples of test results for residual solvents.the stinging is an ongoing issue for which we still don't have an answer, but their test results starting to come back, with first published today for Tirz30 tested as 31mg and 99.6% pure
the stinging must be something related to their filler
if it was a microbial contaminant you'd likely already have seen the ill effects (infections aren't subtle). I'd be much more concerned about toxic residual solvents from the manufacturing process that weren't effectively filtered outI’ve seen reports of stinging from June, July and August orders and from before and after they started vacuum sealing.
I would feel a lot better if we can figure out the source (likely ph or filament… but could be something more serious like sterility)
Do you know if these tests include GCMS testing for residual solvents? I've just confirmed the Jano offers this testing, but I can't find any examples of test resultsI don’t think they have fixed it since people are still experiencing the stinging/burning after they initially stated they fixed it (it’s why they went to vacuum sealed vials).
Has anyone tried to push the issue with them at all to see if they have an answer as to the why?
There is a big test of T30/T60 that includes sterility testing so hopefully it rules it out..
Next is to figure out the ph of the stinging vials (only seen ph for one non stinging vial that was slightly acidic). And even then if the ph is too high or too low is this actually going to hurt the RS or is it just a minor discomfort when injecting?
There are test to check the fillament used too that might be helpful to do….
Only tests I've seen have been for peptide purity/quantity and a few for sterility. Nobody has looked for other things that I know of.Do you know if these tests include GCMS testing for residual solvents?

There have been numerous tests done, including for TFA which is the "evil solvent" everybody panics about, along with heavy metals, endotoxins, and countless other concerns and the end result is always the same: nothing to worry about.Hi, I'm new and have been asking around specifically about GCMS testing for residual solvents vs HPLC testing for purity, and so far I can't find any examples of test results for residual solvents.
The solvents used in solid-phase peptide synthesis are often really, really, really toxic, even in small amounts, and this would be my biggest concern. Do you know if these groups are testing for harmful contaminants or just testing for the amount of tirz in a vial?
I can testify to this. Brand Oz pen had stinging & bruising occasionally over 9mo using. So did c. Pharmacy version sema. And C. Pharmacy tirz.How much hay needs to be made of this? You start googling around and find stories of Ozempic, Wegovy, Zepbound and such stinging on injection as well. You gonna get a refund from them too?
Has this ever been verified? It can be really hard sometimes to sort through educated best guesses based on logic and the very limited info available and actual verified facts in the grey market peptide world. This statement about the source of grey market raws is one thing I've seen come up multiple times, and seems like a very reasonable possibility, but like so many thing in the grey market peptide world, it would likely be impossible to verify, so i had always thought this fell into the first category. But if you have something that does verify this, it would be great to share.Remember that the 2-3 companies synthesizing the raw peptides in China are part of larger legit pharmaceutical manufacturers that have to meet many standards including the purification process post-synthesis.
Only amount and purity are tested, there are many posted examples of COAs in this forumHi, I'm new and have been asking around specifically about GCMS testing for residual solvents vs HPLC testing for purity, and so far I can't find any examples of test results for residual solvents.

the peptide manufacture process is nothing like cooking meth in your basement, so yeah, logically there are not many actual raws manufacturersHas this ever been verified?

My replacement batch of t10 is also stinging a bit….I messaged them the other day after I bought some t, they said the stinging was an isolated issue and to rest assured.
I received Semaglutide from Amopure 2 weeks ago without Mannitol. It hurts as much as GHK-Cu to inject. It is awful. I also find that an identical quantity to that from Sigma is far less effective. But overall the stinging is really, really bad.
Sucks - there is a test being run on Amo’s sema so hopefully we can confirm purity
Which weight vials did you get? Also you can contact Amo and they will replace them.I received Semaglutide from Amopure 2 weeks ago without Mannitol. It hurts as much as GHK-Cu to inject.

It did only the first pinning of T60. I am thinking that the next one that I mix I will let sit a few days before use. I’m wondering if it just needed time to dissolve fully.Wanted to see if stinging / burning is limited to T10, T15, T30 and R10 or has anyone seen any reports, here or in other forums, about it also impacting the T60 batch from Amopure?
How far in advance of pinning did you mix and when did you order? Curious if mine is from the same batch.My L60 works like a charm. No food noise almost immediately. No burn , no reaction whatsoever. Will definitely buy again.
