Just got back from Mexico...purchased 8 5mg bottles of Humatrope. Here are my questions...how long should 8 5mg bottles last? Homie I bought from says 3 mos...but I find that hard to believe. Second...how much dilution do I add? I heard that I should only add 2 ml of the dilution water. I should put the mixed solution in the rest of the dilution water? I am very confused. This stuff is super expensive and I would rather not mess up the dilution...any information would be greatly appreciated. Thanks
