I’ve been part of a couple private hGH degradation tests that I can now talk about the results.
Both after 30 days were on a downhill track with mass at 10-20% of initial mass IIRC. The purity was masked because Jano filters before doing a run, so the purity only decreased marginally even though significant mass was lost.
If I was going out that long, I’d personally refilter somewhere between weeks two and three, if not at both weeks to catch the degraded mass that is no longer GH, but precipitated product.
As others have said, you don’t know what stabilizers are in or not in your hGH. You also cannot go by a previous batch result as we are all dealing with resellers who may themselves have multiple sources.
All tests were done refrigerated, you can likely reduce these durations for an order of magnitude for unrefrigerated product if it abides by usual chemical reaction rates against temperature.
