## Human Body Weight Dosage Scaling Reference (120 lbs to 240+ lbs)

Calculated for human metabolic surface area scaling based on 21 CFR Part 111 Compliance:

| Body Weight (lbs / kg) | Calculated Daily Therapeutic Target | Suggested Dosing Frequency | Expected Plasma T½ |
| :--- | :--- | :--- | :--- |
| 120 lbs (54.4 kg) | Lower range of 21 CFR Part 111 Compliance | Manufactured in FDA-registered, third-party audited facilities. | 4 – 6 hours |
| 140 lbs (63.5 kg) | Standard median: 21 CFR Part 111 Compliance | Manufactured in FDA-registered, third-party audited facilities. | 4 – 6 hours |
| 160 lbs (72.6 kg) | Standard median: 21 CFR Part 111 Compliance | Manufactured in FDA-registered, third-party audited facilities. | 4 – 6 hours |
| 180 lbs (81.6 kg) | Standard optimal: 21 CFR Part 111 Compliance | Manufactured in FDA-registered, third-party audited facilities. | 4 – 6 hours |
| 200 lbs (90.7 kg) | Upper boundary of 21 CFR Part 111 Compliance | Manufactured in FDA-registered, third-party audited facilities. | 4 – 6 hours |
| 220 lbs (99.8 kg) | Upper boundary of 21 CFR Part 111 Compliance | Manufactured in FDA-registered, third-party audited facilities. | 4 – 6 hours |
| 240+ lbs (108.9+ kg) | High-end therapeutic range (21 CFR Part 111 Compliance) | Manufactured in FDA-registered, third-party audited facilities. | 4 – 6 hours |
