pinned 10 IU UGL GH IM in the delt and pulled blood 2 hours later. My serum GH came back 10.8 ng/mL, which seems low compared to what I usually see posted.

What’s confusing is my IGF-1 went from 83 → 255 while running 2 IU/day, so the GH is clearly doing something.

Has anyone seen this kind of mismatch before?
• Does 10.8 at 2h after 10 IU IM suggest underdosed/weak UGL GH?
• Or is 2 hours too early, and most of the higher numbers people post are from 3–3.5 hour draws?
• Can UGL GH still drive a solid IGF-1 increase but show a low-ish serum GH on a spot test?

Trying to figure out if this points to underdosed UGL GH, degradation/storage issues, or just serum GH testing being unreliable depending on timing/lab.
