Some people say that china don't have GH purity over 98%,I want to say that is ridiculous ,here take a look, my client's testing report at Janoshik: HGH API 99.1% purity .
MESO-Rx
Anabolic Steroids
HGH purity over 99.1%

you can get any purity you want from the manufactures in china but sources are too cheap to pay for the 99%

Starting purity is important, but meaningless when nothing is done to protect it. When the wrong PH quickly degrades it because there's no buffer to control it once reconstituted, along with random amounts of (usually crap) BAC used to reconstitute it, it may as well be 80%.
Pharma doesn't add all these extra excipients to the same active ingredient because they like to waste money,
Notice all the good brands keep PH of multi dose products (vs immediate use) in a fairly narrow range of 6.8-7.5? Outside of that range HGH falls apart fast. When was the last time anyone checked what they had in their vial of UGL HGH?

I like that Table. Nice.

Looks like a ph of 6.25-6.5 using a citrate buffer provides the greatest stability of rHGH.
But considering so many current formulations are using phosphate, I'd want to know why before saying citrate is better for sure. Seems the crappy brands use citrate.

What is your excipient recipe for this tested vial?

except gh, only mannitol and glycine

No ph buffer or modifier? What are the details on your water sourced as solvent? From my current researching these all affect pH and possible formation of aggregates and its efficacy post reconstitution.
Purity is only a part of the efficacy equation.

We used to have ph buffer or modifier but not at the moment.
We use the ultra clean water for lab use ,over the demand than medical using.
We have years of experience in gh vials production, and then decide that.Still not bad customers feedback. Easier ingredients mean less potential harm .

I do get a laugh out of the tired trope where Chinese products are regarded as second-rate. YES, they can be - when the objective is to produce MASS quantities of something for a high volume market. This happens to be a good fit for Chinese manufacturers and producers because China's population is exorbitant, lending itself to a labor-intensive competitive advantage.
But do people not recognize that Chinese kids are doing calculus in the American equivalent of 7th grade, or - ever been to a casino? See the massive wads of cash Chinese tourists are waving around?
The Chinese are capable of anything they put their minds to. They're ingenious just as the Yankees and Dutch and Germans, etc.
This was but to belabor my point that, yeah, QSC produces reference grade rhGH, among other highly pure chemical products, basically.

I think that is the reason why Meso Forum is the best place to talk about bodybuilding items. Because here always some big dogs with deeply thinking about things. They maybe not talking too much, but they always there and show up on sometimes.
Because of these smart persons, people in this forum can use the cheapest price buy the best quality products, except the Chinese producers, nobody in the world can provide them in such a good quality and low price. For example like Ozempic(semaglutide) and Mounjaro(tirzepatide) ,what price and quantity they provide you?Of course, they are famous brands, but semaglutide and tirzepatide has already exist for a long while.
I have to say QSC is a very competitive company, but hope they don't sell that low prices, make business so hard and boring .
