Lab vs Lab, We tested 5 Labs using the same Kit.

@hectoraponte Unc Wang only does limited runs of 10 bottles at a time...or i bought a sticker maker.
Thank you randy!

@beachfun We have a second kit of this we are using for some other degridation tests. Lio'd on a windowsill, in the fridge and in the glove box of my truck. Check back in 3 months.

I just watched a video that said the true way to test if a product is what it actually is sold as is to have it tested with Liquid Chromatography-Mass Spectrometer (LC-MS) to actually tell if it actually the correct peptide. I thought that is what a purity test covered, but looking at this image above, I guess I am wrong.
What vendors are tested like that and what testing labs are actually using this? I see Freedom might be, if I am reading that right.
I apologies in advance, new to COA process and trying to learn more on it.

@randy Do you think kits are ever mixed?
I have the mind set that it’s just business and people in china are doing the right thing… I still pin it anyway@jimmy4407th what do you mean, mixed?

@jimmy4407th what do you mean, mixed?
@Randy I should have clarified. Different patches in one kit.

So how do you determine your mass to use if it varies from different vendor?
I recently had GHK-CU 50mg order. The vendor COA (Jano) had two vials. 54.84 and 55.22. The second party vendor paid COA (Jano) came back at 54.83, 52.31, and 53.24. Close to the first but just a slightly lower average. The 3rd party COA (Trustpointe) came back a fair amount lower at 51.280 and 50.735. Are you still taking an average of all vials to use as your vial's mass for reconstituion? -

This is exactly why I do not use the “test” among for my calculations when reconing it.
Had an entire kit tested using multiple labs and they all varied. Some came in at 18.xx and others came in at 20.xx.. I think one might have even came back 22.xx, can’t remember exactly.
I just use the label amount (int my case 20m)) unless it comes back a lot lower, like the SS-31 from a group buy that came back at 40mg. In that case, I use the 40mg -

Since we never know exactly how much is in any individual vial, it will never be exact. I had just figured the dose would be a little strong or a little weak depending on the actual content in a particular vial. But the more I kept reading, the more I saw people stating they use the average since it may make a big difference in some peptides. But the average varying so much in different tests throws a big wrench in the theory of using the average as a standard.

@Nuncles
Exactly. I bought 20 Kits of Reta 20mg. 15 are for me and 5 for a friend. The 4 or 5 labs came back with different values. So how can you possibly use the average? I also noticed a trend with the labs. Most of the time they seem to be consistent with the difference between them.
So what labs results do you use to average them for dose? Unless you have a true manufacturer that intentionally overfills (I believe Lobster does this), you really can’t average them unless they are way off. I had MOTS-C that tested 49mg (labeled 40mg), I might do it with that big of a variation, but not with a 20mg that tests at 21.xx by one lab because it could test different by another.
Some labs seem to be off more times than not.
And what if you are averaging 22.3, 22.6, & 22.1 for reta 20mg because say iLS came up with those numbers. Then you have a problem and you “feel” like it isn’t really as strong as the Reta you got from a different vendor before. But your previous vendors test results tested at 18.59 & 18.78 and you averaged those numbers. And you “felt” like the Vendors Reta was better or “stronger” it simply could be that it really was 20mg but the way that lab tests come up with lower numbers. -
@Commander I won't lie I sort of have been doing this, since I got mine tested and sometimes came above and sometimes came below. Curious are most people just going with what label they bought instead of the COA?

@islander671 For me depends on the lab. So if it's Janoshik, I trust the numbers, and a vendor like Nexaph is testing 3 vials for ID, Purity, and Content If they're all different, like NAD+ 490, 525, 519, I just use 500. But like on Reta 24, when all 3 are above 28. something, I use 28. I just reconstituted these, so I had the numbers handy. Its a little different if they test one vial. The other thing is I find that the larger numbers have larger variations, like NAD+.

I don't see reta on their website, will they be selling or sold reta? New to this world, and this is seems to be a signal of who to trust in a world that seems really hard to find a trustworthy provider.
Eli Lilly has went after a lot of vendors for using the name "retatrutide" so all have slightly different naming conventions. You may see it at GLP-3 or GLP-3R or "Triple agonist" or some variation of their own names. Southern Aminos has it as SA-3R. Most will have a 3 and R in there somewhere for Reta just like Tirzepatide will probably have a 2 and T in their names.
