igf blood test

I just finished a Tesamorelin cycle and my peak IGF-1 levels were 480. I did not test baseline, and I am curious of when I should go back to the lab to see where I stand naturally. Thanks!

I ran 1 vial of blacks or 15iu per day for 12 days and I was taking godtropin prior to blacks. Batch #32 It seems that high doses of HGH could have diminishing returns in terms of IGF levels. Honestly I actually have a poor muscle building genetics and my natty testosterone and IGF levels...
