I'll post the results tomorrow

is the Jintropin the Hong Kong pharmacy one or black market one? I've tested recently the Jintropin 4IU from Hong Kong pharmacy, very high purity.

SDS PAGE


Light Gray Top: noticed some vials in the kits are loose, powder chunk loose.
Some are solid 'cake' tested both. The loose vial would be slightly cloudy. Both took a while to go clear.
Jintropin from the same GH supplier.
Jintropin issue: when I grabbed another vial yesterday to test it from same kit I had opened I noticed one beige brown powder. Upon recon, very yellow. Tested both.
Blue Top from GC
Homer Kahn's Dark Gray
Chinese hospital GH (8iu on the box) from GC
If we look at the SDS-PAGE we first see the red arrows those indicate impurities.

In lane 1 we see a Hygetropin that was used as Reference Standard
The Hygetropin has some small impurity bands this time, because of the rethaw of single use reference aliquots I made using a fresh vial. So every time you freeze and thaw you lose potency from degradation. not bad though I’d say. The intensity of the bands are different, that’s concentration. The Hygetropin gives a fat band just like the GH in 6 and 7. The Blue Top in lane 4 shows the smallest band and is probably around 4 iu.

In lane 2 and 3 we see the Jintropin they are underdosed not 10iu, and YELLOW ???
In lane 4 the Blue Top strongly underdosed, around 4 iu. As I have posted earlier you can buy GH in China at 4/6/8 and 10 iu, many guys in China AND in Europe will try to sell a 4 iu vial as a 10 iu vial. It looks that happened here.

In lane 6 and 7 we see the Dark Grey and the Chinese Pharma GH they show fat bands and seem to be properly dosed, both have impurities from lower molecular weight then the 22 kDa rhGH

The Light Grey Top vials in lane 8 and 9 show HIGHER molecular weight bands then the GH, that can´t be degraded proteins, because those are from lower molecular weight. These Light Grey tops contain Gh and other unknown proteins

The Dark Grey Top and the Light Grey Top come from the same supplier yet the Dark Grey is pretty good and Light Grey isn’t. I doubt that Light Gray Top is from same factory, that would make no sense. Those band patterns are like 'finger prints' they should be the same but they are not.
At Wong ..dunno which Hong Kong Pharma this one is. Hope you like the result.

What is GC? GenSci? We tested Jintropin Hong Kong straight from pharmacy with receipt and tested 8IU and very pure. I've seen a bunch of yellow jintropin, is fake definitely not real and causes bad knot under the skin after injection will stay there for weeks at least, no red skin reaction though but bad anyway.

GC is the seller of the vials.But you know as well as I do that almost all products are counterfeited, and most probably we just analysed a counterfeit.
