Looks like I misspoke, I thought my baseline was lower than it was, 86 was the baseline and you see the jumps over time (just logged in to see the exact dates and numbers)
Dosage of gh was anywhere from 2iu to 4iu, maybe 4iu on the April test? Not sure. The GH Im pretty sure was legit the 133 was on a source we all know and the second was GH from another source well known on forums.
AAS at the time was never than 400mg at any point (usually test./tren, just test, or test/anadrol).
Diet was always about 3k calories, maintaining my weight (so never a huge defecit or surplus). Gh was always taken in the AM prior to fasted cardio, at times split between AM before fasted cardio and then the rest of my daily total PM before bed.
You're likely just relatively GH insensitive. This is not cause for alarm, you do deviate from the mean of the normal distribution of IGF-1 serum levels, but that's OK.
Circulating GH-binding protein (cGHBP) levels, I would think yours are fairly low, are generally reflective of GH receptor sensitivity as GHBP is derived from GH receptors, basically they are cleaved off from the GH receptor at the cell membrane [1].
"At low GH concentrations, when GH receptors are in excess of free GH, a comparable response to a given amount of GH is expected in all subjects, whereas at a higher GH concentration, the response becomes correlated to the expression of the GH receptors (by levels of cGHBP)" [1].
As we know, at your normal levels of GH and IGF-1, you're healthy. That's what matters, not some arbitrary range. But GHBP levels are the greatest contributor to the wide variations in individual response to GH.
You do not need an endo to get your IGF-1 levels up. Hell, IGF-1 is not something you want chronically elevated unless you are banging hGH and YOLOing like some.
Basically, this just comports with wide interindividual variation, and your observation that you may just be a "poor converter."
