I see noone wants to asnwer your question here. Use 191, has to do with the number of amino acids. Do a search in the steroid forum under 191 and or 192 and you will get a lot of info with brands being named. US scripted gh - growth hormone (somatropin) - should all be 191. Jins, Ansonome, Hyg's and many others all 191, would go that route it you are going overseas. Blue top generics good to go too. Do the Plat search. Good luck. I'm over at AF, and just was looking in here and have seen noone answering you.
