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

Couldn’t resist and ordered HGH from the promo - price was just too damn tasty. No idea why though, considering there’s already 2000+iu chilling in my fridge like it’s a hormone apocalypse bunker.
it’s hard to resist. i have PTSD from not hitting QSC’s final promo with all i could beg borrow or steal for. every time i see an SSA promo, i feel a lot of pressure to get something.

Micli is solid, ain’t she.
 
Saw a janoshik on TR60 that was taken by a user and not "eve@sigmaaudley". Been searching like crazy but cant find it now. The senders name was something like "six thirty" iirc... anyone have this one saved? Or another client test?
 
Yes, agree.

It seems silly how everyone is so fixated on “purity” but in reality purity is a subjective target that is changed based on the identity of the impurity (“excipient” vs not)

Just tell us what is in there and how much of each. Of course, that might require more work by the lab and thus money
You underestimate the difference between:
a) confirm the peptide id, figure out the amount and normalize the purity
and
b) id and quantify everything in the sample

It's roughly 10 fold or more.

And if you want to ID even traces ( like those antimicrobials present in TRACE amount that get caught only because they are very UV responsive ), get ready for another bump in the cost.


Half the labs around fuck up just IDing the known peptide if the client intentionally mislabels it and people still use them.
 
@janoshik is it possible to make an order to figure out what these other excipients are as being discussed above? Are they typically automatically removed from purity calculations?

All this talk has me interested now on quality and what else is contained in the lyophilized content besides the actual peptide that is being purchased. Thanks.
If we figure out the excipient or are VERY confident (but not 100%) on the excipient, we remove them.

Normalisation purity assessment is based on the fact you can only compare SIMILAR compounds, eg. peptides and proteins and their impurities, because they share common denominators.

A trace amount of something can end up having more signal than tremendous amount of this or that peptide, so the entire point of that procedure is all sorts of screwed up.
 
I know Jano will give a more detailed answer, but understand when analyzing a peptide you have to specify what it is. That's because the detection "window" is narrow so you need to know what you're looking for in advance. Anything outside that range goes undetected.

It's only when an excipient just happens to be detectable within that window that it can be seen, identified, and removed from purity calculations.

You really can't search for "all possible excipients" using any reasonable testing method. You could request "test for m-cresol" or whatever.
We run screening methods, so a lot of stuff does get detected, but man, having to deal with random chemicals added etc if a brutal pain.
 
Can someone tell me what guaiacol smells like?
It’s really hard to describe. It’s a strong petrochemical odor. As soon as you stick the needle in the vial the odor escapes. When you inject it you taste it in your mouth. In high quantities you can smell it a good distance from the person injecting it. It’s not pleasant

might have been mine
