@Ghoul would never try to discount
@janoshik testing. Or would he?
Here are just a few of his posts about Jano.
Jano's testing doesn't detect structure for proper folding. Pharma uses a bioassay after HPLC on every batch to check for proper binding to verify proper structure, but there are other methods.
There's a lot more to efficacy than a simple measurement of the active ingredient.
Clowns are all about "the science" unless that science comes from somewhere other than Jano's HPLC machine.
Just preempting the nonsensical distortion of Jano's results we may hear, that there's no longer a justification to call out vendors for vials without vacuum, because "it doesn't hurt anything, Jano proved it.".
Though especially for rHGH, because it's exceptionally complex, it applies to all peptides. The way in which these are being tested doesn't capture the way these compounds degrade.
The stuff that reconstitutes cloudy, ie aggregates, still ends up with 96%+ purity on Jano tests.
Jano's testing leaves a lot to be desired in terms of detecting what constitutes degradation.
There's more to it than just purity.
No one can answer this question without testing that goes beyond what Jano does,
These claims are based on a flawed testing methodology that doesn't measure the loss of stability, backed up by "feels" that "prove" if it has any effect, it's "fine".
I recently read a study that measured degeneration the way Jano did in the studies used to claim Tirzapatide is impervious. When they corrected the error, purity went from approx 95% to 65%.
The very basic testing that Jano does for these small private groups does not overturn the facts that thousands of scientists who develop and work with peptides every day have established over 60 years.
Flawed tests. You don't see what's not being measured. There is no testing of aggregation or the amount of active ingredient lost as a result. Jano's basic testing is not overturning what the rest of science has long established as fact.
It's you who presumes every batch of UGL Tirz has the same stability, or that Jano's basic $200 test disproves the science established by hundreds of the world's top chemists.
You realize Jano is running a small analysis lab. He's awesome and a great asset to the community. But he's not a biochemist, pharmaceutical engineer or medical researcher. In other words, being able to analyze a sample doesn't make him an authority in all things pharma.
