EC50 determination is reliable Scenario B: 85% pure IGF-1 LR3 stock (1 mg/mL) At a nominal concentration of 100 ng/mL in assay, actual IGF-1 LR3 = ~85 ng/mL Remaining ~15 ng/mL consists of potentially inhibitory, partially active, or bioactive contaminant species Dose-response curve is shifted
In controlled studies with GHRH analogs, glucose uptake was preserved as long as IGF-1 stayed within the age-normal range
Haematological malignancies, liver cancers, and some solid tumours may elevate B12 through increased binding protein production or release from damaged tissue, though most elevated B12 cases have non-malignant causes
This composition enables it to perform efficiently in various bodily functions, including DNA synthesis and repair, metabolism of toxins and carcinogens, and enhancement of the immune system's response to infection
