Kigtropin comes as a freeze dried white powder – 10 x 10 IU (3.3 mg) vials per box. Like several others it started as a made up brand name which became popular due to good reviews in the bodybuilding community. It is manufactured by an unknown Chinese lab – which seems to be a common practice some Chinese companies use to avoid the HGH legality issues.
Positive forum reviews outweigh the negatives by 8:2 which would indicate that Kigtropin is a solid HGH of high quality.
Some users have reported painful red welts around injection spot which would indicate low purity and higher levels of bacterial residue. The cause of red welts might also be a 192 amino acid sequence HGH mimic – which produces similar results as real HGH but comes with a dangerous immune reaction side effect.
Kigtropin is most likely produced by a proper Chinese GMP Lab who due to legality status of somatropin chose to not make themselves known and are rather pursuing the black market route. Due to the nature of black market, anyone with an interest can counterfeit/copy their HGH of questionable origin and sell it as Kigtropin. Quality thus depends on the trustworthiness of the source.
