Its super easy to reconstitute. You take a 100iu slin pin and draw to the 8 with Bacteriostatic Water. Swab the top of the vial of course. Then hold the plunger firmly upon entering the vial. If not the pressure inside the vial will pull the water from the pin into the vial forcefully, possibly damaging your HGH. Now angle the pin towards the side of the inside of the vial and SLOWLY inject the water into the vial. Then gently swirl the water around, DO NOT SHAKE IT!!! Refrigerate immediately. You now have 8iu's of HGH ready to inject. You inject it (Sub Q) into the fat on your stomach above the navel area. The same as you would HCG or Slin. You can also inject on the fatty part of your thighs. I'd start @ 2iu's a day for a couple weeks and then slowly ramp it up week by week until you get to your desired dose. Hope this helps.
