How to Use This Calculator
- Enter body weight: Input your research subject's body weight in kilograms (kg) or pounds (lb). The calculator converts automatically.
- Enter dose per kg (or flat dose): Input the protocol dose in mcg/kg if weight-based, or toggle to flat dose and enter the total mcg per injection directly.
- Set injection frequency: Choose how many injections per day (1, 2, or 3) to calculate total daily dose.
- Enter cycle length: Input the total number of days in the research cycle to calculate total peptide needed and vials required.
- Enter vial size: Input the vial size in mg. The calculator returns exact vials needed, rounding up to ensure you have enough.
Example Calculation
A researcher is running a 28-day Ipamorelin protocol at 200 mcg per injection, twice daily. They have 5 mg vials.
| Variable | Value |
|---|---|
| Dose per injection | 200 mcg |
| Injections per day | 2 |
| Total daily dose | 400 mcg/day |
| Cycle length | 28 days |
| Total peptide needed | 400 × 28 = 11,200 mcg |
| Vial size | 5 mg = 5,000 mcg |
| Vials required | 11,200 ÷ 5,000 = 2.24 → 3 vials |
Weight-Based Dosing Reference
Common research protocols expressed as mcg/kg, converted to absolute doses for three reference body weights:
| Protocol dose | 60 kg | 75 kg | 90 kg |
|---|---|---|---|
| 5 mcg/kg | 300 mcg | 375 mcg | 450 mcg |
| 10 mcg/kg | 600 mcg | 750 mcg | 900 mcg |
| 15 mcg/kg | 900 mcg | 1,125 mcg | 1,350 mcg |
| 20 mcg/kg | 1,200 mcg | 1,500 mcg | 1,800 mcg |
