I used GH for 12 months several years back and normally purchased the JIntropin from Gensci which came in the square box at 100iu. I also did some of the Kefei as it was cheaper.

I am preparing to obtain 8-10 kits for my wife and myself and there is a substantial price difference between the KeFei {30% cheaper} than the GenSci JIntropin. It's been so long now that I can't remember any difference between the two except that MAYBE I did not have as much arthritis / cramping in the hands with the KeFei as the Gensci. That may have been because I changed to the KeFei 7-8 months after using GenSci.

For someone who has done both, what is your reccomendation? Spend the extra $1,000 on 9 kits for the Gensci or stick with the KeFei?

Thanks,

Farrar
