Jintropin 191 amino acid and Kexing 192?

[mick-G]

GENESCIENCE JINTROPIN

Jintropin is the most popular rHGH sold in China. According to IMS, an internationally recognized marketing firm, Jintropin is the absolute market leader in China with just over 75% market share.

Jintropin and Lily's Humatrope use a technology called secretion technology which will produce a 191 amino acid sequence growth hormone, with much less E.coli protein contamination and not any side effects associated with injection, such as red painful welts. This technology also has the advantage that growth hormone produced using secretion technology is very stable; it can be stable at 37C or 98 degrees for about 30 days. While growth hormone with192 amino acid sequence is only stable at room temperature for just a few days.

KEXING FITROPIN

To manufacture their rHGH, Fitropin, Kexing is using a technology called inclusion body technology, which can only produce a 192 amino acid growth hormone, very similar to Genentech's old growth hormone, Protropin. Growth hormone produced by inclusion body technology is very easily contaminated by the E.coli protein used to express the HGH. A very common side effect of this contamination lack of product potency due to degradation of the HGH and painful welts at the injection site.

Kexing's growth hormone's first amino acid is Met, while Jintropin and Lily's Humatrope's first amino acid is Phe (which is identical to natural growth hormone produced in your body). Because Kexing's first amino acid is Met, this indicates clearly that Kexing's growth hormone must have 192 amino acids with met being the extra amino acid.

PLEASE NOTE: all the rHGH manufacturers in China, (Kexing, Anke, United) except for GeneScience use the inclusion body technology.

This is correct info...most studies are done many years ago about the 192 amino acids...almost everyone that I come accross who is or was on Kexing says its very good HGH and would def. do it again....it also claims that Kexing is 99.9% pure form of GH...

i have read somewhere that kexing is no good since it is 192 and will cause u probs in the future

Like what????

This is what the artical is saying. Basicly the inclusion body technology that produces the 192 amino acid sequence, alows more contamination of the E.coli bacteria which leads to painfull welts at injection sites and the degradation or lack of potency of HGH. It is also less stable at room temperature, only lasting a few days. Whereas the Jintropin and Humatrope has a stability of around 30 days at room temp. and uses the secretion method which yelds the 191 amino sequence and less chance of e. coli contamination. Although, i have heard of good results with the Kexing, i personally wouldn't what the risk of contamination.

as fat as i remember it was like health prob since the extra 1 amino is not good, i 'am trying to find the link for it for u can read it, it was on a different board, let me find it

Guys, the 192 studies were done long ago and with HGH that was not as pure as we have today. Yes Kexing is 192 but it’s not in an impure form as the old ones. Its 99% pure. There is a test which shows Kexing and Jintropin purity and Kexing shows up bit more pure.

Anyways….The 192 amino acid theories is that it will produce GH antibodies and after you discontinue its usage the antibodies will still remain and work against your natural GH production. But then again these are old studies with old HGH and only small % of people could develop antibodies.

Also, this is the first I hear of Jintropin being kept in room temperature for 30 days and still being able to keep same strength. It even states on its packaging its stable in room temperature for up to 7 days.

So which is better I see people liking both with Jin as the overall fav amoungst GH users!!!!!!!

Re: Jintropin 191 amino acid and Kexing 192?

At this time its a personal choice.....they are both good....

Re: Jintropin 191 amino acid and Kexing 192?

I hear they are both good. This article is just disturbing. Jintropin is the most widely used gh.

my friend did kexing and didnlt like it coz gave him the bloat and gen lei is better, i personnally like 191 , since i have done ELILLY the 191 and like it a lot

Re: Jintropin 191 amino acid and Kexing 192?

I hear good and bad about kexing for me I'd go with jino's. I hear there's another brand from China Progenis Genitropin but I don't know if it's 191 or 192

I have been contacted by someone informing me the original post is most likely completely INCORRECT, I'm waiting to hear from a kexing rep and I will post the info

Re: Jintropin 191 amino acid and Kexing 192?

I hope so bro. This artical is just kind of disturbing. I would think that the Kexing rep would be bias though.

I'm almost certain the one above was written by a jino rep and or supplier
