Ah, I see what you mean. I wonder how much of an increase you'll see on your next lab results. Although, I've read that sometimes IGF-1 lab values on bloodwork can be an unreliable indicator of GH potency. Something about blood levels only reflecting unbound, circulating IGF-1, and not IGF-1 that is actively bound to cells. Don't quote me on that, though, because I admittedly don't know much about this, so this could be wildly inaccurate.
Is this your first run of GH, and do you plan on increasing your dosage? I've read about the neuropathy-like symptoms from GH that some experience (allegedly from water retention / swelling compressing nerves). I plan on starting at 2iu/day and slowly titrating up to maybe 4iu - 5iu per day, depending on symptoms/tolerance/results.
