I have never tried the Humatrope, but have taken the Nutropin AQ for 5 months or so at a time (ie: when the cash is available...or i would continue year round). The Nutopin AQ comes reconstituted, 2ml vial, 10mg vial. I shot 1.5 iu (pull stopper back to 10 mark) upon waking and 1.5 iu post workout late afternoon/early evening. I love it, hands get thick feel real solid, body temp gets elevated, very vascular, felt like my sex drive went up...so i can't say anything but phenominal with the Nutropin AQ. I believe Humatrope is just as awesome....EINSTEIN is who i listen to, hopefully he posts. Later dude.
