Since 192 amino acids hGH is less stable than 191,I've heard some person talking about that fitropin/Kexin is 192 or Jino 191,Now I don't know who are right.
Fitro is 192 aminos and jin is 191. The first amino in fitro is met, which shows that it has a 192 amino profile. It is less stable than jin and also much more susceptible to e coli.
