HCG degradation testing after 30, 45, 60 days

Is there a way that we can test/confirm that QSC's HCG is recombinant?

@janoshik can you chime in on whether there's a way to confirm with >95% certainty whether a vial of HCG is recombinant or not?
There's certainly a way but I don't know it... However, I feel we might be past the point when recombinant is cheaper and that's pretty bulletproof indicator for what manufacturers are going to use.

I want mine to come from urine, or I'm not interested. Same with my GH, I get better pumps and vascularity when I know that a corpse was sliced open for my sake to extract its pituitary gland.
 
We have 2 data points:


Sample...Manufacturer....Excipients.....Reconstitution....30-day degradation
1................Liska.................?................Sterile water.............18.1%
2................QSC..................?.................BAC water................0.9%


Now the question is: Does the BAC water lead to reduced degradation, or the presence of (PH-stabilizing) excipients that may or may not be in the QSC product?

For those who think it's the BAC water: What's the mechanism here? The BAC water prevents the growth of airborne bacteria that otherwise would eat up the peptide hormone? @janoshik, what's your preferred explanation?

I believe the bacteriostatic water reduce degradation, because the product do not have any pH-stabilizing excipients. Only mannitol filler.

There is actually one more data point from this study I mentioned earlier: The influence of different excipients and storage procedures on hCG (human Corionic Gonadotropin) as evidenced by spectrophotometry - Nature Precedings

Sample...Manufacturer........Excipients........Reconstitution....30-day degrad.
1................Liska.....................?..................Sterile water.............18.1%
2................QSC......................?...................BAC water................0.9%
3................Pharma.......phosphoric acid.....Sterile water.............~0%
......................................&sodium hydroxide.........................................
......................................&Mannitol.......................................................

I honestly don't know, but my wild guess would be living organism induced degradation - while usually insignificant, with Hcg dosed in microgram range it could have more impact relatively.

Surprising results in the full text even though it is not relating to BAC water. Zero degradation between 4 and 25ºC. If this is accurate, then traveling with HCG would be MUCH easier.
