I have not used the sources you mention but they may both be real and they may both be fake. Fake is a word usually misused. The vast majority on the market is real 191 its just copied. So the questions are this; Did your product get underdosed, 1 mg that claims to be 3 or more. What is the purity level in terms of percentage of strands meeting the standard of 191. Is your product mixed with hcg or peptides or is it all hcg or peptides? Lastly and least common, is it just an unknown powder all together. A lot of homework is needed and the way you do that is to find actual people that have used the source that know 191 through experience and can confirm the source to be quality. I sent you a pm with a source I have used since switching sources for 5 weeks or so. At this time I give the source 5 stars for customer service and 3 stars for quality since it is early. Given the carpal tunnel signs increasing I fully expect to rank the quality at least a 4 but I just need a little time. It is definitely 191 and relatively strong, just how strong and pure will take time and testing....you'r on the right track researching and asking questions, there is a ton of crap in the HGH world. If you happen to be a milliionaire and can afford 100 bucks a day or more I can get you an Eli Lilly source! lol

I use the one labelled .com.cn at the moment, it is very potent, My understanding is that .com.cn and .com are both legit good quality GH, i do not know about pro.com but pretty much all Hyges are real GH , I have never heard of Hyges that do not work, some are fakes made by other GH companies to cash in on the name and some are made by Dr Lins new company but they are all decent GH just some better than others.
