Somatropin vs somatotropin

[Conrad1980]

I have looked at hgh from china.
one type is called somatotropin
cas 9002-61-3 and the other somatropin cas no 12629-01-5

Somatropin is what I have heard of and is probably what is common.
somatropin is recombinant hgh. rhGH
What does it mean that it is
recombinant.
What is the difference between these substances?

Pretty much all of your pharma GH will be somatropin as far as I know. I believe the cadaver produced GH was halted in the late '80s.

Notice I'm not saying the Chinese somatropin is pharma.
Most Chinese GH is referred to as generic GH, but the contents may vary greatly.
There's good and bad "generic" GH, so be very thorough in your research.

The fda.gov website gives about he best definition.

Recombinant human growth hormone is a protein that is manufactured to be nearly identical to the main form of the naturally occurring human growth hormone. This hormone can stimulate tissue growth, linear growth (height), and protein, carbohydrate, lipid, and mineral metabolism.

Edit: There's a difference in the number of amino acids. I never can recall the number without, but I believe all pharma is 191aa.

Google will help you out there.

[Conrad1980]

Yes. 191aa is pharma, while 192aa is produced cheaply in China.
They have added 1 extra amino acid to make it easier to produce. The effect decreases and the side effects increase.
I'll have a good look.

I can't afford real Hgh and it's usually fake from China too.
I don't trust hgh until I join myself and get it from the pharmacy.

Also, some people react poorly to the 192aa.
