| Dosing | Clinical doses of every active on the label | Trace amounts, there to be listed rather than to work |
| Manufacturing | Produced to Good Manufacturing Practice standards | Standards vary, rarely stated |
| Fillers | Formulated without unnecessary fillers | Bulking agents padding the scoop |
| Shipping | Free on US orders over $199, tracked | Shipping added at the last step |
