Is the Janoshik screening for contamination worth it ?

1x GCMS/LCMS screening for contamination x 170 USD = 170 USD

What exactly does this test, if purity is over 99% does it test the remaining % or ?

I like to see everything as a risk potential; with these peptide orders the risk is mainly that you get something less pure or even something different. Contamination is very rare, and I understood that Jano implied it's not needed, but the risk is never 0.

From seeing his interviews I am focusing on maintaining sterility of an opened vial from the first use. From what I've learned here on the filtering topics I am also filtering everything.

screening for contamination and endotoxin came back fine on the SSA rt30 but sterility failed

STG mods say it's normal and just filter.

I don't care too much about purity unless it's degradingly rapidly... There's a link somewhere on this forum that name brand only has to be 97%. Purity to me is more like a benchmark saying they're trying.

A bunch have failed sterility, the smart thing to do is just filter it every time. A filter is like $1, an extra $1 per vial won't kill anyone.

The important part of testing for me is mass. So many come overfilled, I see 10-20% pretty regularly and we've had cases where it was almost double. I'd be pretty miserable if my dose was double what I expected.

It was 41% underfilled at 17mg with sterility fail.

contaminants, endotoxin, purity, heavy metals all came back fine.

Purity testing over 99% says nothing about contaminants, sterility, etc. The vast majority of material in the vial is excipients and not the API we care about. It's just about how degraded or not the API is.

Something might fall behind a shelf in a hot warehouse and get discovered years later and be 85% purity, but that won't say it's any more or less likely to be contaminated than something that is 99.93%

My guess would be they messed up and sent you overfilled 15's (I'm assuming this is tirz?) since that's also a standard size. Sterility fails aren't uncommon, most don't even check for it. I'd want a replacement of refund for the underfilling though.

there was another random test from finrick yesterday at 16.8. RT30 728D is 15mg mislabeled.

728W tested at 33mg and 38mg, 2 samples each.

No replacement from SSA
