if they were so righteous, they would not be putting this out there and selling it to begin with. They would rather profit very well knowing that their product could cause health problems and are protecting themselves with "transparency". If anything this makes me trust them less for other products.

It doesn't have to be a gamble, that's why COAs, reputation matter, and these forums exist. Same backwards logic with people that still buy bunk brands after several negative reports. If people keep buying regardless of the trash they sell, no pressure to produce higher quality products.

Ahh ok.. must not of went through the whole process yet. Hopefully soon.
Thanks for the info

You’ll find out after first shot. Goodluck

I don't know anything about this stuff but I wonder if its possible that the 11% be denatured gh.

Good question to ask before using it, and I'll give you the honest breakdown of what that missing percentage could actually be because it's a real consideration, not a trivial one.
First, the framing: when GH purity testing (like Janoshik) comes back at, say, 89% or 92%, that number tells you how much of the lyophilized powder is actual growth hormone. What the testing does NOT tell you is what the remaining percentage is and that's the crux of your question. The third-party test measures the GH content; it doesn't identify the rest. So you're right to wonder what fills that gap.
What the remaining percentage could be, roughly from most benign to most concerning:
The benign stuff (best case): A lot of the non GH content in a legitimate vial is supposed to be there the excipients and or binders that stabilize the lyophilized powder. Things like mannitol (a sugar alcohol used as a bulking agent and stabilizer), glycine, sucrose, or sodium phosphate buffers. These are normal pharmaceutical fillers, harmless, and present in real pharmaceutical GH too. So some of that missing percentage is just standard stabilizers, which is fine. Your "baking soda?" instinct is in the right ballpark some of it is inert filler type material that does no harm.
The "doing nothing but wasting your money" stuff: Degraded or denatured GH growth hormone that broke down from heat and handling and is no longer biologically active. It's not necessarily harmful, but it's not working either, so you're getting less real GH than even the purity number suggests if some of the "GH" has denatured. This is why cloudy reconstituted solution is a throw-it-away sign denatured protein.
The genuinely concerning stuff (why low purity matters): This is where your instinct to be cautious is right. The non GH fraction in underground generics can contain:
• Other peptides entirely the vial might be cut with cheaper peptides, or contain growth hormone secretagogues (GHRP-2/6) relabeled or mixed in, which cause their own effects (hunger, prolactin, cortisol elevation, water retention). You'd think you're getting pure GH and actually be getting something that behaves differently.
• Diuretics some generics have been found to contain small amounts of a diuretic (like furosemide), which masks the water retention GH causes, making the product seem "cleaner" or higher quality than it is. You'd be unknowingly taking a diuretic.
• Anti-diuretic compounds the opposite, making you retain water and bloat, which an inexperienced user might misread as "potent GH" when it's actually just water and rising blood pressure.
• Bacterial contamination this is the real safety concern. If the vial lost its vacuum (someone took the manufacturer's top off and put a fancy branded top on, which breaks the seal), bacteria or endotoxins can get in. Injecting bacterial contamination is how you get injection site infections, abscesses, or systemic reactions. This isn't theoretical it's the actual risk with improperly handled underground vials.
• Dimers and aggregates GH molecules that have clumped together (dimerized or aggregated), which can be immunogenic your body can mount an immune response against them, which is both a health risk and can reduce the GH's effectiveness as your body produces antibodies. Aggregated protein is one of the more concerning impurities because of the immune reaction potential.
• Endotoxins bacterial breakdown products that can cause fever, inflammation, and systemic reactions even if there's no live bacteria.
So to directly answer your question: the 11% could be anything from harmless mannitol filler (best case) to bacterial contamination, relabeled peptides, diuretics, or immunogenic aggregates (worst case) and the purity test does NOT tell you which. That's exactly why low purity is a red flag: it's not that the missing percentage is definitely dangerous, it's that you don't know what it is, and the range of possibilities includes genuinely harmful things. The uncertainty is the problem.
Now, the practical guidance, because you said you're stocking up on GH and about to use it:
Purity threshold: The general rule people use is that 95%+ is good, and below 90% is where you should be cautious not because 89% GH is inherently dangerous, but because a larger unknown fraction means more room for the concerning stuff. So your instinct to stay away from sub 90% is reasonable.
But purity alone isn't the whole safety picture and this is important for what you're doing. A vial can test at decent purity for GH content and still be contaminated, because the purity test measures GH percentage, not sterility or what the binders are. So you need more than just the purity number:
• Check the vacuum. A real vial holds a vacuum. If it's got a fancy branded top but no vacuum when you reconstitute, the seal was broken and contamination risk is high that's a throw-away sign regardless of purity.
• Check clarity after reconstitution. Cloudy means it’s denatured or contaminated just bin it. Clear is what you want.
• Test it. Since you're stocking up, sending samples to Janoshik for purity testing is worth it but understand it tells you GH content, not what the rest is or whether it's sterile.
• Test the dose cautiously. Before going to full doses, inject 1 to 2 IU and watch for an adverse reaction injection site redness, pain, swelling, feeling unwell. Do that for a few days with a new batch before trusting it. That's your real-world contamination/reaction check.
The honest bottom line for you: the missing percentage in low-purity GH ranges from harmless filler to genuinely dangerous contaminants (bacteria, endotoxins, immunogenic aggregates, relabeled peptides, diuretics), and the purity test can't tell you which so the danger isn't certain, it's unknown, and that uncertainty is exactly why low purity is a legitimate concern. Since you're picking up GH based on price, be careful that you're not optimizing for cheap at the cost of quality underdosed or contaminated GH is no bargain. Stick to 95%+ purity where you can, check the vacuum and clarity on every vial, test the dose of new batches before trusting them, and send samples for testing given you're stocking up. The "is it baking soda or something harmful" question is exactly the right one and the answer is "could be either, you can't tell from the purity number alone, so treat unknown filler as a risk rather than assuming it's harmless." Don't inject anything cloudy or from a vial that lost its vacuum, regardless of what the purity test said.
