Source hierarchy
Primary
When available, Glone prefers official product labeling, FDA materials, trial publications, and directly attributable public references.
Method
Method notes describe the exact transformation used in the calculator, such as unit normalization, interpolation, or modeled schedule generation.
Limits
Where a tool uses assumptions instead of direct label language, that assumption is stated on the page rather than implied as medical truth.
Calculation families
Dose and units
Dose conversion tools use explicit arithmetic such as mg/mL normalization, U-100 syringe math, pen-volume assumptions, and vial transition continuity.
Nutrition and wellness
Protein, water, fiber, and ideal-weight tools use published formula families or clearly bounded heuristic ranges intended for routine planning, not diagnosis.
Planning and modeling
Cost, timeline, missed-dose, titration, and plotter tools may interpolate trial curves or apply schedule rules, so their results are framed as estimates.
What is direct math vs modeled output
Direct-math tools use deterministic formulas. If you enter the same inputs, the result is exact within the rounding rule documented on the page.
Modeled tools use embedded curves, population averages, pharmacokinetic assumptions, or label-based branching. Those outputs are useful for planning, but they are not individualized predictions.
Sensitive tools receive stronger disclaimers and visible source-review framing so the page itself communicates the difference between a formula and an estimate.
Implementation notes
Public tool pages are statically rendered for search, while the calculator UI runs as a client island. Canonical URLs stay clean even when a calculator restores state from query parameters.
The calculation layer is stored separately from page components so formulas, validation rules, and optional share-state logic can be tested independently from presentation.
Query-state support is only used where it materially improves sharing or repeatability, such as the GLP-1 plotter. It does not change the page’s canonical metadata.
How to read tool results
Treat low-risk conversion results as arithmetic assistance, not prescribing authority. Treat modeled planning outputs as orientation aids with explicit limitations.
If a tool result conflicts with product labeling, your prescription, or clinician instructions, the label and your clinician should win.
