I buy peptides from China. I've seen oils and hgh in vendor catalogs for extremely attractive prices, but I don't have the balls to import a scheduled substance. At least peptides still fall into that "for research purposes only" gray area of deniability... for now (hence the ever growing stash in my freezer).
Look at example 2 though.... with respect to calculating threshold pyrogenic limits using non intrathecal administration of b12 @1000mcg/ml concentration and a 14.3mcg/kg recommended dose from the product information. It takes into account both concentration and recommended dosage to establish the limitSorry let me clarify.
The info is pulled from the FDA:
It refers to exposure in a 1 hr period, and the safe limit in humans is 5 EU per kg of body weight. Suppose your tirz dose is 15mg, you'd be tripling that limit when you do your weekly bolus shot (since that would be half the vial which contains a total of 2300 therefore 1150 in that one shot).
I got the 350 safe limit using 5 EU/kg for an "average" person around 150 - 170 lbs. A bigger dude could handle slightly more, but not by much.
The one hour window bit admittedly confuses me a little, as I understand endotoxins can also build up in your system with repeated exposure.
I hope I'm explaining this in a way that makes sense?

. Or Van...tell me what I'm missing please. Lol.
I guess that's the way to calculate a safe dose if you know the EU/mcg in the substance being administered: take the EU/mcg number and the safe dose is whatever keeps you below that 5 EU/kg threshold.Look at example 2 though.... with respect to calculating threshold pyrogenic limits using non intrathecal administration of b12 @1000mcg/ml concentration and a 14.3mcg/kg recommended dose from the product information. It takes into account both concentration and recommended dosage to establish the limit
So then Assuming the 5EU/kg threshold pyrogenic limit (TPL) established for such a parenteral administration, it yields a 350EU/ml limit that the product b12 can safely contain.
to calculate the TPL for other substances administered in a similar fashion, you would have to apply both the dosing of the substance and it's concentration to the equation to yield proper TPL, no? Similar to what's shown in example 2.
I know my math has been know to not math at the best of times....so would the real math-ers...please stand up... you know who you are
The reference to per hour goes above my head as well in how it is being used. I could take a stab but I feel it would be wildly incorrect. I was brave enough to take a gamble on the above, but not that.
Idk, now i'm paranoid... don't want to mistakenly buy from this source. unless i didnt read enough ...any other info would be great for some of us that doesn't know which to avoid... tyvm
I'm not looking to fear-monger here. According to jano, this is the first peptide test which has ever failed for endotoxins. The vendor probably doesn't matter a whole lot. There are a handful of major labs producing peptides in China, and the vendors are just middle-men. It remains to be seen if this tirz was tainted at the lab, or during processing/packaging by the vendor. We'll have our answer if other vendors start popping for endo as well.
