With a serostim kit, the concentration will depend on how much of the sterile water you use to reconstitute with. I believe each vial contains 6 mg or roughly 18 ius of gh (remember we're talking weight - not volume here). So if you inject 3 cc's (perhaps a bit much) of the sterile water into the vial to reconstitute then you've got approx. 6 iu's per cc. Knowing this you can use the volume indicators on your syringe to administer (1/2 cc or 50 units to administer 3 iu's in this case).
A couple things to keep in mind.
1. Serostim comes with sterile water. Unless you plan on using an entire vial (18ius) at once then throw the water out and get some bacteriostatic water to reconstitute with. GH reconstitued this way can stay good in the fridge for a week or two whereas if you use the sterile water, any gh not used within 24 hours should be discarded (18 iu is a lot for one administration not to mention hell expensive).
2. If I were you I'd stay away from Serostim unless you got it from a Pharmacy ( and maybe even then ). There's way too much fake stuff out there - read my post in the "more fake serostim" thread where I give links to the proof.
