Aye, I’d agree with this lad. He’s not wrong.
Jano can correct me if I’m off, but from what I understand, his tests focus purely on the protein profile, meaning what proteins are actually present in the vial, and how much of it is active, properly folded HGH.
You’re getting key info like:
- Purity % — how much of the protein content is genuine 22 kDa HGH. Usually around 90 to 99 percent in good batches.
- Dimers % — how much is clumped together, which sure can lead to immune response if it's insanely high. *
- Fragments % — bits of broken or degraded HGH. Useless, really.
- IU (International Units) — a measure of how biologically active the batch is, regardless of total weight.
What he doesn’t test for are things like mannitol, glycine, salts and so on, the non-protein stabilisers. Those won’t show up in the report because they’re not proteins. Doesn’t mean they’re not in there, just that they’re not relevant to that specific kind of testing.
He also doesn’t routinely check for sterility or endotoxins, but there’s a reason for that, and it’s not negligence. Proper sterility testing takes two weeks, under controlled lab conditions, and it’s expensive. Same goes for endotoxin tests like LAL or rFC, you’d need specialised gear, and it’s usually done by pharma companies as part of full QA protocols. Not something most third-party labs can afford to run on every batch.
So instead, Jano focuses on what he
can measure with high accuracy, fast turnaround, and low risk: protein structure, activity, and purity.
And if something’s wrong, like foreign proteins, high dimer levels, or degraded fragments, it’ll show. He flags unknown bands in the protein gel, and purity drops like a stone. You can’t hide garbage protein from that sort of test.
Long story short, if his report says 96% purity, 0% dimer, and high IU, it’s clean. If something dodgy’s in there, it won’t stay hidden.
*dimmers: Small amounts of dimers (1–5%) are common even in pharma and usually harmless.
It's my view the immune system only tends to react if you’re injecting large amounts of misfolded or foreign protein repeatedly, and yes, HGH is taken daily, but that’s not a problem unless the product is badly made.
The fear around dimers has been blown out of proportion by some (pharma or overly cautious users), though it’s not completely baseless in extreme cases.
