As u can see each "vial" contains "10" IU and the whole box would therefore have 100IU. Often these "Kits" are available for anywhere between $100-$200, for 100IU, sure.
This same amount varies in price of anywhere between $8-15 /IU for pharm grade depending upon vendor such as UGL vs a local pharmacy. Rhetorically, why is it I don't believe an ill defined UGL in someones garage which normally produces AAS can make rGH and price the product at as low as ONE TENTH the pharm grade cost?
The only Gh which approximates "kit" packaging that I've aware of is Norditropin, which IF SPECIFIED is available in a three pack SYRINGE SET. Fact is, probably 80-90% of existing GH manufacturers have converted to, and are packaging, a self enclosed syringe delivery system.
Why? As a primary means of deterring counterfeiting, (characteristically the syringes are mechanically embossed using proprietary equipment) notable exception, Chinese rHGH, what a surprise, NOT!
However, if your referring to "kits" being the GH products forwarded for formal lab analysis, admittedly I'm not familiar with aspect of GH testing.
