The idea is that at individual scales the additional load is ignorable, but at mass scraper levels it adds up and makes scraping much more expensive

The LIP is dynamically set by transferrin/TfR1 uptake (iron import), ferritin (safe storage via H-chain ferroxidase activity), NCOA4-mediated ferritinophagy (ferritin degradation releasing Fe), heme turnover by HO-1 (which can paradoxically raise LIP if not matched by storage/export) and mitochondriallysosomal exchange routes that shuttle iron for heme/FeS biogenesis
They are deducted from a range of glutathione, which was prepared with the same conditions as dosage did
You are not alone, and the story is more complicated than testosterone simply being the villain
