Like thats key, measuring things
Current research has delineated several pivotal axes in ferroptosis regulation: iron homeostasis modulation (e.g., NCOA4/TfR pathway), antioxidant defense (System xc /GPX4 axis), and lipid remodeling (ACSL4/ALOX15 pathway)
The 10 ng/mL of IGF-1 remarkably increased collagen production, while the 10 and 20 ng/mL of IGF-1 treatment did not significantly increase collagen production compared to the untreated cells (Musson et al., 2017)
They work best when combined with balanced eating, movement, and consistent use
Each of these could contribute to slower absorption and less visible effects, so its possible that you may need a higher dosage than someone who exercises often, doesnt smoke, and drinks little or even not at all
