The key to success with GH is the duration of use, not the number of iu's per day. I can't tell how the hell you are calculating your conversions, but the answer above is correct.
One thing is clear, though. You are using 6iu a day, ED. This is probably too much per day and your cycle will be too short.
Most of the research, and my personal experience, says that you need 6 to 8 weeks to see good results, and 12 to 16 weeks, even at a lower dosage to achieve maximum benefits. I think that you will find you need 3 or more kits.
And most researchers also agree that high doses per day of hGH results in waste because the body's natural defense mechanisms negate the effects of high doses. Those who lack these defense mechanisms have acromeglia........giantism.
I have used as much as 12iu a day in the last 4 weeks of a 12 week cycle of GH, pyramided up from 6iu. I saw no better results than on a 16 week cycle at 4.5iu throughout...........oh, maybe a little leaner, but not enough to justify the expense.
You need to experiment with several cycles of different dose to find what works for you......everyone is different. I'm going to go year round at 2.5iu a day and see what I get. My friend who does this looks great.
BTW, iu's measure mass, not volume, so insulin iu's are not the same as GH iu's.....but no GH dart exists, so we make do with insulin darts and do a little math. But no matter what, a 6mg. Serostim vial will yield 18iu's........it doesn't make any difference how much dilutent you add.
