Sorry for delayed reply. I asked our technologist to provide me the technical background & test results and was waiting till I get them to furnish my explanation with proofs. All this chemical things... It is a bit difficult again, I try to transmit this Info how I understood it in simple words.
I start from afar. Human growth hormone (HGH) is a polypeptide hormone. There are differents isoforms of HGH. The human body has 5 genes responsible for production of HGH by our body. They all are located in the 17th chromosome. But they are responsible for production of different types (isoforms) of HGH. The main isoform is a "full-value" growth hormone consisting of 191 amino-acid residues. It has the molecular weight 22127 amu (22 kDA). (This value is very important, because we use it in our tests to find proper raw materials. I explain later). It is synthesized and secreted by the anterior pituatary gland. However, for example one of the genes is responsible for producing another isoform of HGH by a women placenta as example. And this growth hormone is chemically different, another isoform. Generally in our blood stream can be found several types of HGH (at least 5 isoforms). However only one of them is a full-value HGH with 191 amino-acid residues. Its chemical formula is C990 H1532 N262 O300 S7. And this form is the main form which can be found in our blood. The second isoform which can be found in blood has molecular weight of only 20 kDA. In this form are missing amino-acid residues from 32 to 46, that is why the molecular weight is less. There are also shorter forms of HGH with less molecular value. You will see in the attached file the description of each isoform, the number of residues and molecular weights of each isoform.
By the way, I am sure you heard about different peptides which become popular now, they are a part of this complex structure, for example HGH Fragment 176-191, which consist only of indicated residues.
So...
cbass00, while replying your question I say you are right, the most sources sell crap and you will see it in the results attached. Lot of manufacturers buy raw materials and sell HGH under their own brand. At this the most factories producing HGH are located in China. This is the same situation as with sport nutrition. There are only several factories, which produce raw materials for BCAA, different acids, etc. And they all are in China. Most of brands buy the powder, add aromatics and resell the products under their own brand.
Well, if you ask me, whether we produce HGH ourselves or use "chinese crap", I reply that we do not produce HGH ourselves and buy raws from Chinese manufacturers.
BUT: what we buy is for sure not crap. We tested lot of raw material manufacturers and the results are attached. Last time we had kind of a "call for tenders" between HGH manufacturers in the beginning 2014. Our employee made anonymous small orders at the main manufacturers available in China and we tested the samples. By the way, we included into the tests also the most famous brands of growth hormone Kingtropin and Jintropin, which were bought anonymously from resellers. These are samples Nr. 4,11 and 12 in our tests. These were samples bought not as raw material, but as final products, in packages, at retail price, etc. As you will be able too see both of them did not consist any HGH at all... Famous brand means not always quality guarantee as you can see. I guess that were fakes, because we bought them not directly from manufacturers, but anonymously at resellers. Other samples we bought as raw material directly from manufacturers, had HGH, but not all of them as well. Sample 2 and sample 5 were not HGH. Only 7 of 12 tested powders were HGH.
However, this is not the end of the story. As you can see in results, 3 of 7 HGH samples had not the "full-value" HGH with 191 amino-acid recidues and molecular weight 22 kDA, but that were "cut" isoforms of HGH with the molecular weight about 17 kDA and only 153 amino acid residues. Lot of manufacturers produce not full-value HGH and sell it as a growth hormone. Only 4 of 12 examined samples had real full-valued HGH with 191 residues.
This is also not the end of the story... the quality can be good, but there is also the question about the weight content of HGH. We took the same amount of the powder from each sample and performed the tests and found out that samples have different amount of HGH itself. You can see the values in mg in the file attached.
Conclusion:
When we chose suppliers of raw materials for HGH we:
1. Work only with suppliers offering the full-value HGH with 191 amino-acid residues. This is very important for the efficiency of HGH. I just provide the first scientific article I found to this topic:
Code:
http://www.ncbi.nlm.nih.gov/pubmed/11720906
You can read there one simple sentence: The 20 kDa form has been reported to have
weaker diabetogenic and lipolytic actions than the 22 kDa form. And the shorter form are even weaker.
2. In addition to the that we control also the weight content of HGH in the powder.
Guys you can see, that we totally examined the samples and used several testing methods: electron spectroscopy, mass spectrometry and PAGE (polyacrylamide gel electrophoresis). So we are absolutely sure in the results.
If you buy our HGH you can be sure that this is full-value HGH and each vial has the manifested 10 IU.
p.s. Probably someone will ask, why the test result is so old. I reply. As I said, it was the last result when we organized a "call for tenders" and chose one of several raws suppliers. We chose one supplier and now there is no need to check other suppliers. We buy big batches of raws from this only supplier, perform the chromatographic analysis of each new raws batch we buy and this is enough. Since 2014 this supplier offers and provides us raws of enough high quality and we know to value stable partnership relations and provided high product quality.
I hope herewith I thoroughly replied the question about our HGH.
I can not attach the file. cause it exceeds the allowed size. Here is the link:

And one more thing: i translated this file today into English, so I hope it will be enough clear for you, whatever some mistakes in the terminology, etc. are possible.
