Ok i got my gh kits lilly humatrope 24mg (72ius) cartridges. It comes with 3ml of diluting solution. In the instruction manual it says that it has a self life of 28 days once it mixed should i use the diluting solution that came with it or should i use bacteriostatic water and should i mix the same amount of bacteriostatic water (3ml) like the diluting solution that came with it. Do you think that the bacteriostatic water will give the gh a longer self life (28days) than the diluting solution that came with the gh ?
