I see everyone posting labs on there gh, and people freak out it is important to note that we are all different and we all test differently, with me and my husband running the same gear my labs would say the gear is bad, his labs would say its good, and I run more, so I did some research and found this info, maybe it can help someone answer some ???? A normal range for human growth hormone levels is difficult to define because of the normal physiological fluctuations in HGH concentration. In most adult subjects at rest, after an overnight fast, the HGH level in serum is 7 ng/ml or less. Age, sex, lifestyle, can all make this number vary. Changes in HGH levels in response to various stimuli gives a more accurate assessment of pituitary dysfunction.
